What’s the best tourist SIM card for Japan (2024 guide)

By: Author Kris

Posted on Last updated: August 18, 2024

If you’re headed to Japan and want to stay connected while exploring, we’ve got you covered with the top tourist SIM cards. No need to worry about losing touch with your loved ones or missing out on those Insta-worthy moments.

We’ve spent a lot of time in Japan and traveled all over the country. The first trips we would very often come across a “Handy” phone in our hotel room – a phone we could use throughout our stay. But those days are long gone now.

Nowadays, if you want to stay connected, you better have a local SIM card if you don’t want to rely on public hotspots. And trust me, from experience, we can assure you that a local SIM card is still highly recommended.

There are several spots offering free internet, mainly in the larger cities, and handy apps to connect to WiFi hotspots for free. We share more information on this app in this article. Still, there are still plenty of places that require a data subscription for internet usage.

Whether you prefer the convenience of ordering physical SIMs online and picking them up at the airport or exploring the innovative world of eSIMs, there are numerous ways to ensure you stay connected on your journey.

Japan Tourist SIM cards – The top choices

In this article, we discuss no less than 30 different Japan tourist SIM cards.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

We discuss all the details of the SIM cards further down in this article but here are our top choices:

For the occasional data user

Most SIM cards offer unlimited data but all providers have implemented a fair usage policy. If you consume more than what is covered by the fair usage policy your data speed will be reduced. Sakura Mobile cannot share the exact details of the fair usage policy, therefor we recommend them for occasional use. Their prices are very competitive but they cannot be used for video streaming or as a hot spot for your laptop.

If you just want to make sure that you can fall back on your data plan if you need it but you already know that you will only have to use it occasionally, these are your best options.

Short stays

At JPY ¥4,000 for 8 days the SIM cards provided by Sakura Mobile are reliable and very cheap. 

The SIM card offers unlimited high-speed data at 4G or 3G speeds.  You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country.

Thanks to the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there. If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible (see our FAQ below) with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

Longer stays

If you are 2 of 3 weeks in japan.

For stays of 2 or 3 weeks , you’re in most cases also best off 16 or 21-day cards of Sakura Mobile that can be found on Klook.  At JPY ¥6,000 and JPY ¥6,500 they are the cheapest options that can be found for these durations.

Both SIMs offer unlimited high-speed data at 4G or 3G speeds.  4G is offered in major cities while the 3G is applicable in more rural areas. You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country. It has a coverage of over 99%.

Once you have read through the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there.

If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

If you are longer than 24 days in Japan

If you will be in Japan longer than 24 days the 30-day card of Simcard GEEK that costs JPY ¥4,980 is a good buy.  The card comes with 7GB of high-speed data which should be sufficient to cover your needs.  This SIM card also connects to the NTT Docomo network which is generally recognized as Japan’s best network.

Simcard GEEK has a fair usage policy of 3GB/day.

For the heavy data user

If you want to be online the whole day,  enjoy streaming music, or watch YouTube videos, you’re better off with the below SIM cards.  This may also be the case for those who will be sharing your data plan with friends or family members, maybe by means of a mobile WiFi device.

These SIMs also have a fair usage policy. In this case, however, you know the details of the policy and can therefore pay attention to it so that you are not faced with surprises.

Mobal offers SIM cards for 8 or 16 days with an unlimited data plan .  The cards have a fair usage policy which limits high-speed data to 3GB per day. 3GB is quite a lot, it will allow you to browse the internet for 36 hours, stream 600 songs, or watch 6 hours of standard definition video. 

Consuming this amount of data in one day would probably mean that not much time is left to see the many stunning sights Japan has to offer.

Mobal has a SIM with an unlimited data plan for 31 days.   This card has a fair usage policy which limits high-speed data to 3GB per day. 3GB is a lot, in the previous paragraph we gave a small overview of what exactly you can do before you reach this threshold. 

If you go out and discover the city you will probably never consume that much data in one day and if you stay in your hotel you can use the WiFi provided by the hotel.

Sakura Mobile

Sakura Mobile is a reputable Japanese company that specializes in providing wireless services for visitors to Japan. They offer a range of affordable solutions to keep you connected throughout your stay.

They offer English support. Our support question was answered quickly, correctly, and in clearly understandable English.

One standout feature of Sakura Mobile is its compatibility insurance option. For an additional fee of 500 JPY, you can add this insurance to your purchase if you’re unsure whether their SIM will work with your device. This provides peace of mind and ensures that you’ll be able to stay connected without any hiccups.

In the unlikely event that you do encounter connectivity issues, Sakura Mobile offers a solution to those who took the insurance option – an upgrade to a Pocket Wi-Fi device at no extra cost. Alternatively, if you prefer, they can also provide a refund.

You have multiple options when it comes to ordering Sakura Mobile SIMs. You can either purchase them through Klook or directly on their corporate website . While the widest range of options is available on their own site, it’s worth noting that Klook offers certain exclusives not found on the corporate website.

On the other hand, when ordering directly, you can choose from more pick-up locations or have the SIM shipped to any address within Japan, including hotels.

Size : Multi-size SIM cards. Normal, Nano or Micro sim.

Network :  NTT Docomo (3G & 4G)

Shipping :  When you order through Klook the SIM can be collected at Terminal 3 (the International terminal) of Haneda International Airport or Terminal 1 and 2 of Narita International Airport. There is also a pick-up location in the arrival lobby of the Kansai airport.

If you order direct you can have the SIM delivered to hotels and Airbnb’s or collect it at the airport (Haneda, Narita, Kansai, Chubu, New Chitose) or at the office in Shinjuku.

Activation : No activation is required for these SIM cards. They’re ready to use. You just need to insert the SIM and set the APN.  You can download a document that explains how to do this.

Available direct :

Available through Klook :

Japan SIM cards with pick-up abroad (via Klook)

Here are a few extra options for those who live in Thailand, Malaysia, Hong Kong, Vietnam or India.

The below providers offer SIM cards that are either shipped to your home or that can be collected at your airport of departure.

Personally I would prefer to pick-up my SIM in Japan.  This has the advantage that somebody can assist you with setting it up and in the unlikely event that it doesn’t work, you would be able to look for an alternative or arrange a refund on the spot.

A pick-up abroad might, however, be a convenient option if you don’t want to lose time collecting your SIM upon arrival.

Buying a SIM card in Japan

Don’t worry if you’re already in Japan when you’re reading this. 

It’s also possible to buy a tourist SIM card in BIC Camera and Yodobashi Camera stores as well as at Narita and Haneda airports. 

You can even order one online and pick it up in several locations in downtown Tokyo, Kyoto, Osaka as well as other cities.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport terminal 3 (see here and here ).  The sales points from the operators will likely be able to better assist you and give you advice while the stores from BIC camera will likely be cheaper.

In the cities

Another option to buy a SIM card in Japan would be to head to one of the BIC Camera or Yodobashi Camera stores in the cities. 

They sell various prepaid SIM cards for Japan tourists.  Usually, someone will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they would at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is. But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

Finding these stores is easy.  Your hotel should be able to tell you the nearest one or you can use Google Maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend.  It is a fun experience during which you can marvel at all the electronic gadgets that are for sale.

But maybe you prefer to compare the various options from the comfort of your hotel room.  This is possible as well. 

You can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

They have a very informative website and offer English support in case you have any additional questions. 

Japan eSIMs

Good news if you have a modern phone that supports embedded SIMs (eSIMs). You no longer have to worry about fiddling with your phone to replace the SIM card. All you have to do is click a link or scan a QR code.

Your SIM can stay in your device and you can switch between your own cellular plan and the Japanese plan. Super convenient and super easy.

Four providers offer eSIMs :

Simcard GEEK

Airalo esims.

Frewie offers 2 eSIMS for use in Japan. When ordering a Frewie eSIM through Klook you will get a confirmation mail with a QR code to activate your eSIM. The mail is sent within 24 hours of your purchase.

The Frewie eSIM is a data-roaming SIM that connects to the Docomo network in Japan. It’s not a native Docomo eSIM, you will need to activate data roaming for it to work. Because it uses roaming it can be somewhat slower than the above eSIM options from Simcard GEEK.

One SIM works only in Japan, the other works in Japan & South Korea. Both are data only. The data package varies with the duration of the SIM.

Japan SIM card for longer stays

For a short stay, you’re best off with a prepaid SIM card but if you’re staying in Japan for several months you could consider an unlimited long-term plan.  

Japanese providers are known to have a lot of red tape.   

A contract with them usually requires a lot of paperwork and a commitment of 2 years. For some, you even need to have a residence visa and/or a Japanese bank account.

Two providers offer long-term SIM plans :

Mobal offers an alternative to the red tape. 

Their long-term plan comes with no minimum duration, no activation, and no termination fee. 

The customer service team speaks English, is super-responsive, and you can easily order the SIM card online.

Shipping :  Shipping is always free but not available to all countries.  If shipping is not available to your country you can simply collect your sim for free, at one of the many pick-up locations.  There are locations at the airports and in Tokyo, Osaka, Kyoto and other major cities across Japan.

Shipping of voice+text sims requires that a copy of your ID is sent to Mobal at the time of your order.

Activation : To activate your SIM follow the activation instructions provided with your sim.  During business hours the activation should be processed within 2 hours.

FAQ About Tourist SIM Cards for Japan

Will your phone work in japan .

Before you buy a SIM you need to be sure that your phone is compatible with Japan’s telecom network. It needs to be able to operate on one of the bands used by the telecom operators in Japan. 

Check the technical specs of your phone to see what bands are supported and see if there’s a match with the bands that the operators are using. We’ve listed all of them in the following section.

Your phone will also need to be unlocked.

If you don’t want to do this manually you can find pages online ( like this page ) where you can select your phone and the network operator to verify if they’re compatible.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. Rakuten Mobile used to be a virtual operator but started building out its own network a few years ago. Today it covers about 94% of the population.

All other operators are virtual and use one of the existing networks. The tourist SIM cards we discussed in this article all work on either the Softbank or NTT Docomo network.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second although they are not far behind. Both these networks cover 99% of Japan (population-based).

These are the bands used by the Japanese operators:

Rakuten Mobile

Pocket WiFi device vs Tourist SIM card

One big perk of using a pocket WiFi device is that you can stay connected without having to mess with your phone.

No need to worry about changing your settings. Just remember to turn off your data connection to avoid those annoying roaming fees. With your SIM card still in the phone, you can stay connected with friends, family, work buddies, and anyone else who has your number just like you’re back at home.

If you want people to be able to contact you anytime, a pocket WiFi device is a great option.

Another advantage of pocket WiFi devices is that they let you connect multiple users at once (usually up to 10!).

Batteries of pocket WiFi devices usually last no more than a day. This is probably the biggest disadvantage. It is one more device that you need to charge on a daily basis.

Interested in Pocket WiFi devices?

See which ones you can rent in Japan . Or if you are going to use this often, you can buy your own device , just like us.

Which size of SIM card do you need

SIM cards have become increasingly smaller over the years. First, we had the standard SIM, then the Micro SIM and nowadays almost all modern phones use a Nano-SIM

Usually, providers use multi-size (3-in-1) SIM cards that are compatible with all phones.  Others only offer 2-in-1 (Micro and Nano) which means they will still be compatible with most current models. 

The technical specs of your phone will show what SIM you need.

In some cases, you will need to specify the requested SIM size with your order.

Free WiFi in Japan

You can easily find free WiFi at many places in Japan. Coffee shops like Starbucks, metro stations in all major cities, and JR train stations offer this convenient service.

Connecting to public WiFi networks was a pain the first time we were in Japan. Not only did we, have to do it over and over again. We also couldn’t get the connection to work for half of the time.

But now there’s a great app called Japan WiFi Auto-Connect that takes care of all the hassle for you. It automatically connects your phone to selected public WiFi hotspots. Only the trusted ones managed by reliable companies or authorities are used by the app for security reasons.

The app worked perfectly for 90% of the time during our last trips. Whenever we walked into a metro station or train station the phone usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple and makes free WiFi much more reliable for foreigners.

Still, I suggest not depending on free WiFi entirely, just like we don’t. As you move away from the big cities, finding reliable Wi-Fi spots becomes harder.

And even in the major cities, I find it super handy to have internet access all the time so I can look up stuff whenever something pops into my head – not just when I stumble upon a hotspot.

It’s a matter of convenience, but SIM cards are so cheap that I think it’s worth it.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There’re many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

The Best Way to Stay Connected in Japan

July 12, 2024 by Robert Schrader Leave a Comment

When it comes to getting a SIM card for foreigners in Japan, the topic has become both simpler and more complicated over the years. On the plus side, it’s not impossible, as it was 10 years ago when I first visited Japan.

If anything, there are too many options today. Do you order one in advance, or simply pick it up when you arrive? There are even SIM card vending machines, though these have their own risks—who do you call if it doesn’t work? Then, of course, you can always go the old “pocket WiFi” route.

Spoiler alert: I personally think the most foolproof way to stay connected in Japan buy a Japan eSIM from Holafly before you even board your flight. I’ll explain over the course of the next few paragraphs why I believe this to be the case.

The Complicated History of Japan SIM Card for Foreigners

When I was on the cusp of arriving in Japan for the first time in 2014, I was flummoxed. I’d Googled “SIM in Japan for foreigners”—and I was not happy with what I saw. Due to antiquated laws (which I’d later find out are extremely common in supposedly modern Japan), nonresident foreigners were legally prohibited from buying SIM cards. There were other ways to stay connected, but none were especially attractive.

Thankfully, as the Olympics approached and Japan’s tourism industry ballooned both in size and importance, the country’s legislature repealed most of these laws. Suddenly, you could not only buy a SIM upon landing—you were bombarded with options for doing so. This reality is part of why I’ve created the guide below. If you give me just a few minutes of your time, I’ll give you a complete run-down of all your options.

How to Get a Japanese SIM Card (or Stay Connected if You Don’t)

Buy an esim before you travel.

If you’ve bought almost any cell phone in the past few years, it’s eSIM compatible. This means that in order to use your phone with a different calling or data plan, you simply need to download some code on it (this is essentially what’s meant by “eSIM”) and you’ll be ready to go. When you buy your eSIM, you’ll need to choose a package based both on the number of days you’ll need it, as well as how much data you expect to use.

TIP: If you use my link to buy a Japan eSIM from Holafly , you’ll get an exclusive 5% discount off your entire order!

Get a physical SIM upon arrival

Whether because your phone isn’t eSIM compatible, or just because you’re a bit old school, another SIM card in Japan for foreigners is a physical SIM card. Desks selling these operate in the Arrivals areas of all major airports in Japan; in some cases, you can even find a SIM card vending machine. Your SIM card will allow your phone to work with popular Japanese mobile networks like Softbank and docomo. 

(Or a pocket WiFi)

Pocket WiFi units were the most common way of staying connected in Japan before it was legal for foreigners to buy SIM cards. They’re still useful these days in some cases. For example, if you’re traveling with a group (especially with small children) and want a single “hub” for everyone to stay connected, without having to download multiple eSIMs or buy many physical SIM cards.

Roam using your home carrier

Is it cheaper to buy a SIM card in Japan than to use your home country’s cell phone plan? Well, that depends. Probably not, if you have a globally-focused cell provider like Google Fi. Even if you use a mainstream company (such as AT&T or Verizon in the US), you’ll need to verify whether there’s a fixed-rate “international data pass” you can avail. If not, roaming charges may be much higher (and accumulate much faster) than you expect.

Get by using WiFi and your sense of direction

If you’re just completely opposed to buying a SIM card in Japan, you aren’t without options. WiFi in Japan is extremely widespread—in hotels and on bullet trains, and even in many cafes and restaurants and on buses, subways and local trains. On the other hand, if you don’t speak at least some Japanese, this can be a risky option in more rural places where locals don’t speak any English.

What If I Forget to Buy my eSIM Before I Get to Japan?

Now, don’t be fooled: Although pre-purchasing an eSIM is the best Japanese SIM card strategy for foreigners, you aren’t S.O.L. if you arrive at Haneda or Narita airports without one:

• If you’ve verified that your device is eSIM compatible, connect to the airport’s free WiFi network and use it to access the Holafly website . You can buy your SIM card and install it while you wait in the immigration queue!
• If you don’t have an eSIM-compatible device, not to worry. You can visit a desk or a vending machine to purchase a physical SIM, or you can go super old-school and rent a pocket WiFi.

See? The topic of SIM card for foreigners in Japan actually isn’t all that confusing to understand, at least not in 2024 as compared to 2014.

Other FAQ About SIM Cards in Japan

Can foreigners get a sim card in japan.

When it comes to how to get a SIM card for Japan, it’s surprisingly easy. Foreigners can either install an eSIM before they travel to Japan, or purchase a physical SIM card upon arrival. Alternatively, groups of travelers may choose to share a pocket WiFi, rather than buying individual SIMs.

Is it worth getting a SIM card in Japan?

It is 100% worth getting a SIM card in Japan. While public WiFi is fast and widely available in Japan, there’s value to having a guaranteed connection everywhere you go. It’s especially helpful if you wish to travel off-the-beaten-path in Japan , where having access to Google Maps (and Google Translate!) is indispensable.

Do American SIM cards work in Japan?

If you still feel intimidated after learning how to buy a SIM card in Japan, you can probably just use your US cell phone plan while traveling in Japan. However, I recommend contacting your mobile provider before you travel to verify rates. You don’t want to come home and get a surprise bill for several hundreds of dollars!

The Bottom Line

When it comes to SIM cards for foreigners in Japan, the best course of action in 2024 is to order a Japan eSIM from Holafly before you travel. This way, you can be connected the moment you land; you also don’t have to worry about any extra hardware, be that a tiny SIM card or a bulky pocket WiFi unit. Of course, there are some cases where this doesn’t make sense, whether you have an old phone or you simply have an excellent home country phone plan you’re sure will work in Japan.

Japan SIM Cards: Your Must-Read Guide to Staying Connected in Japan

Plus, the 10 reasons why a Japan SIM Card is your best option!

If you're going to Japan & want to stay connected you'll need to make a decision: Japan SIM Cards, Wi-Fi routers, Roaming & Free Wi-Fi are all options to keep you connected in theory - but which option is best for you and do you really need a SIM Card for Japan? We've done the hard work for you with an ABC Guide on how to get connected in Japan, including some common misconceptions...

A. Free Wi-Fi is not a thing!

Japan has a reputation for being super-advanced but in some areas change has been slow. Surprisingly, free internet is almost impossible to find throughout Japan - even in Tokyo. Most Wi-Fi hotspots are not free & require you to register each use. The free ones aren't exactly free either as they're in cafes & restaurants - so you'll need to pay for food or drinks to connect. If you plan to be on the move rule this option out!

B. Renting a Wi-Fi Router may not make sense!

If you plan a very short stay and are happy to pay daily rental fees, then a Wi-Fi router may be your best option. Remember though that you'll have the hassle of keeping an extra device charged and returning your rental kit to the airport at the end of your trip. An easier and more economical alternative is to buy a data-only SIM. Unlimited Data SIMs are available from 8 to 31 days duration (see: www.mobal.com ) giving you the option to use the SIM in your own device and dispose of it at the end of your trip. You can even use tethering too to connect other devices. Get your SIM delivered to you before you travel so that you can Instagram from the plane on touchdown - or pick-up from the airport when you arrive.

C. Roaming is tricky.

Most cellular providers offer roaming in Japan, but beware - just using your phone for even a short period can result in returning home to bill shock! Some providers such as T-Mobile USA appear to offer great deals with unlimited data in Japan for no extra charge. Note though that data speeds are heavily throttled so this may restrict how you use your phone.

The advice is when in Rome... Get a local Japan SIM and avail of high-speed data and cheap calls if needed. The Japan Unlimited SIM from Mobal gives you data, voice & text with a minimum of 7GB of 4G LTE data per month (larger plans available if needed). If you use more than your high speed data allowance, your data will slow down, but the amount you can use is unlimited - plus, you can buy more high speed data if you need it. You get to control how much data you use, so you'll never return home to bill shock and you'll never run out of data either.

10 Reasons Why a Japan SIM Card is your Best Option

Until recently buying a Japan SIM card for your smartphone was simply not an option for overseas visitors - unless you wanted to sign-up to a complicated 2-year contract with huge fees payable if you left Japan early.

Luckily you can now get a no-contract voice & data SIM as well as prepaid data SIMs - all with English customer service, free incoming calls & free domestic calls on the same network*.

Order online from Mobal and you can choose to have your Japan SIM Card delivered in advance or collect from main airports & cities in Japan on arrival.

If you're still not convinced here's 10 more reasons why you absolutely need a SIM Card for your phone when in Japan!

1. Google Maps

2. phone numbers have status.

Japan is slow to change - think fax machines, single-glazed windows & CDs (yes, really!). If you plan to live in Japan a phone number is a must - you need one to get a job, rent an apartment, open a bank account, ship/receive a package - you basically need a phone number to do just about anything!

For visitors booking hotels and restaurants, a Japanese phone number can often be more acceptable than your credit card, so consider the advantages of a voice and data SIM over a data-only SIM.

3. Shopping Online?

Planning to avail of free delivery to your address when in Japan. Great deals are available from electronics stores such as Bic Camera or clothing outlets like Muji but guess what you need to avail of delivery? A Japanese phone number!

4. Uber/Japan Taxi

If you find yourself out at night (a spontaneous Karaoke night perhaps!) you'll quickly discover public transport isn't 24 hour. If you need an English-speaking driver Uber is useful and Uber taxis don't charge a late-night surcharge - great for getting back home from wherever you are.

5. Eating In is the New Eating Out

Want to order takeout to your room - all from the comfort of your phone? You definitely need a SIM and you may even need a phone number. We recommend you go for the Mayo-Jaga pizza (potato & baked mayonnaise on a tomato base)!

6. Google Translate

Whether it's deciphering zany pizza menus for home delivery or communicating with the locals you will definitely make use of this app. As it doesn't work on batteries we definitely recommend you get a SIM card ;-)

7. Social Media

Being in Japan means lots of photos. Lots of photos means lots of sharing online. Make sure your family and friends are as jealous as possible of your adventures in Japan by keeping them updated through social media! Plus, with average commute times in Japan over an hour you'll end up browsing or wanting to!

8. Music/Podcast/Shazam

Walking through the streets of Japan and hear a song that catches your ear? Don't worry about having to figure out the Japanese to type in lyrics to Google - just use Shazam to find out and discover many new Japanese songs!

9. 4G or LTE speeds

As long as you're on a Japanese network and not an MVNO SIM you'll get the same data speeds as Japanese people do. It's fast as you might expect. Mobal's Japan Unlimited SIM is the only voice & data SIM available to everyone that uses the Softbank network - if you want quality this gets our vote.

10. Emergencies

With extreme weather events & earthquakes a part of daily life having a voice SIM with SMS capability doesn't just mean your analog friends can keep in contact from overseas, it also means you'll receive early warning alerts & updates.

Finally, here are 10 reasons why you should choose Mobal...

• Mobal have been trusted by international travelers for over 30 years.
• You get always on data - Data is totally unlimited, so you'll never run out.

SIM Cards in Japan: Top 7 Services for Travelers in 2024

Stay connected in Japan by using a SIM card! We introduce 7 Japanese SIM cards ideal for short stays along with information on eSIM and the pros and cons of using a SIM card compared to portable Wi-Fi routers.

Mitoyo, Kagawa, Japan

Stay Connected in Japan

There are several ways to access the Internet in Japan. The most inexpensive method would be to use free Wi-Fi, although its availability is limited and can expose users to vulnerabilities.

A SIM card for travelers or portable Wi-Fi router comes in handy in these situations. While the latter can handle a large amount of data, carrying the device around may require some effort.

Alternatively, a SIM card may only handle a little data and is more complicated to set up than a portable Wi-Fi. But it is far easier to carry and cheaper than a router.

This article features seven SIM cards that will support your short-term trip to Japan. We've also included information on eSIM services and inexpensive portable Wi-Fi routers that are an alternative to SIM cards.

Those planning a long-term stay in Japan should check out this MATCHA article .

Ninja WiFi offers three types of SIM card plans:

Nippon SIM for Japan is provided by DHA Corporation and is available on Amazon.

A 30-day plan with 3GB data costs 1,980 yen. There are other plans with a wide variety of duration and data.

Since the capacity is small, this card is suitable for those who don't use much data and looking to buy a cheap SIM card.

5. IIJmio Travel SIM

Picture courtesy of IIJmio Travel SIM

Those planning to purchase a SIM card during their trip should look for IIJmio Travel SIM . It is sold at major electronics stores in most large cities, such as Bic Camera, Yodobashi Camera, and Kojima .

This is an open-priced item with costs varying by store. As of August 2024, a 30-day card with 3GB data is sold for 2,480 yen at Bic Camera.

IIJmio is a low-cost SIM service provider that is well-known in Japan.

6. SIM Cards Offered by Klook

Residents of southeastern or eastern Asian countries should check Klook , an experience booking site.

Klook also sells various SIM cards that are suitable for a trip to Japan. Most of them can be sent to various Asian countries, so please take a look!

7. SIM Cards at Airports

If you forget to purchase a SIM card in your home country, don't worry! In recent years, major Japanese airports are provided with SIM card vending machines.

For example, a 5-day SIM card with unlimited data* is sold for about 3,000 yen at vending machines in Narita Airport. Recently, eSIM  with 50GB of data for 8 days are also being sold for 4000 yen.

Please check the official website for additional details. 

*The internet speed is get slowly when you use a lot of data amount in a few days.

eSIM: An Alternative to Physical SIM Cards

One of the concerns about using a SIM card is the risk of losing the SIM card when replacing it. After all, SIM cards are very small, measuring only 1 to 3 millimeters in size.

Recently, eSIM has been trending because it can be used without replacing the physical SIM card. In the U.S., the iPhone 14 series designed for eSIM use was released in 2022, and other carriers are expected to follow.

Companies in Japan are also offering this service.

As mentioned above, mobal provides this service for 1,920 yen and up (8 days with 1GB data). The price at Sakura Mobile is 3,350 yen for 10 days with 5GB of data. Nippon SIM for Japan also offers eSIM.

If you're using a smartphone that supports eSIM, please check out these other companies as well.

Low-Cost Portable Wi-Fi Routers

In most cases, a portable Wi-Fi router handling a large quantity of data will be more expensive than a SIM card. However, this is not always the case.

For instance, Ninja WiFi router costs 770 yen/day with 3 GB/day. Furthermore, there is a 20％ discount via MATCHA and costs 3,080 yen for 5 days , which is a similar fee to SIM cards.

While it may be burdensome to carry a router, it allows multiple devices to access the Internet with no need to change SIM cards.

Please consider these facts when considering a portable Wi-Fi router.

FAQs about SIM Cards in Japan

Q1. is a voice sim or data-only sim a better choice.

Voice SIM comes with a Japanese telephone number while data-only SIM does not.

With WhatsApp, Messenger, and LINE becoming popular messaging apps, some may wonder why you need a Japanese phone number if you're not a resident.

But a phone number has its advantages. Firstly, users can phone the police or fire department when trouble occurs. Emergency calls can be made in other languages besides Japanese, so this is a major feature.

To apply for various services in Japan, such as the popular electronic payment app Pay Pay, users must register a phone number.

Those who are interested should check mobal, which handles Voice SIM cards suitable for short-term trips.

Q2. What does "unlimited data" mean?

In regards to data traffic, some SIM cards offer "unlimited" data usage.

Most of these types will easily handle 2 to 3 GB per day. However, exceeding this capacity will cause the speed to be reduced. While Internet accessibility remains, the flow of data will be considerably slower.

Q3. Can I change the SIM card of my smartphone?

If your smartphone is SIM-locked, the answer is no. While there are SIM-free phones in most Asian countries, some Japanese and American phones are locked.

There is a way to open these types of phones. Ask your carrier for information on how to unlock your smartphone.

Additionally, please note that some SIM cards may not be compatible with certain smartphone models. There is a compatibility list on the official websites of SIM card providers, so be sure to take a look!

Q4. How should I handle my original SIM card?

If you are going to change the SIM card in your home country, store the original in a dust-free place.

Those who plan to replace the card in Japan should bring a SIM card case. It can be purchased on Amazon and other retailers.

When traveling abroad, get a policy from one of the  best travel insurance companies . You can get a  5% discount   on Heymondo , the only insurance that pays medical bills upfront for you, HERE!

If you want to have mobile data during your trip, consider getting a SIM card for Japan . There are several cards to choose from depending on the purpose of your trip, so I’ll share my top recommendations as well as their pros and cons.

I’ll tell you upfront that we use the Holafly eSIM card whenever we travel abroad, and the company even has eSIMs for Japan . We’ve never had a problem using Holafly, and what I like most about these digital cards is that they’re super easy to install and activate. Plus, the plans come with unlimited data for Japan , so we never have to worry about how much we’re using. You can even get a discount on Holafly for being a Capture the Atlas reader; just use our link.

5% OFF your international eSIM card

That said, if you prefer a physical SIM card for Japan or your phone isn’t compatible with eSIM technology , you can still get internet for travel . In this case, I recommend the Japanese SIM cards from SimOptions , which you can order online and have delivered to your home. Just be sure to order it in advance so you can install it before leaving for your trip.

There are other SIM card plans for Japan , so in this guide, I’ll share the best ones, where to buy them, and some tips for finding the most suitable options for your trip.

How do Japanese SIM cards work?

First of all, you should be aware that it’s against the law for tourists to have a phone number from Japan . In other words, you can’t get a SIM card in Japan that includes phone calls.

Fortunately, you can still get travel Internet in Japan thanks to Japanese data SIM cards that allow you to access the Web. In this way, you can make calls and send messages through a mobile app like Messenger, WhatsApp, or Skype.

When you’re choosing a travel SIM for Japan , always check your device’s compatibility and mobile network first. You don’t want to spend money on a card only to find out once you’re in Japan that you can’t use it with your phone.

If you decide to go with the Holafly eSIM for Japan , I recommend checking your device’s compatibility here . For local Japanese SIM cards , you can check this on the retailer’s website or at the storefront.

Japanese SIM card price comparison

I’m going to share the best SIM cards for Japan , but first, here is a brief overview of my top picks. This way, you can quickly compare the most important stats like price, duration, and amount of data.

You’ll see that Holafly offers the best deal for both short-term and long-term trips. Not only is Holafly affordable, but its cards come with unlimited data, so you can enjoy the Internet without worrying about your data usage. The digital SIM card is delivered via email, so you can purchase it before your trip or when you’re already in Japan.

Of course, I know that some people prefer a physical card, so I’ve included several Japanese SIM cards that you can insert directly into your device. The cheapest option is the Rakuten Mobile SIM, which you can buy from a local store in Japan. The downside of getting this card is that you’ll have to locate a store that sells Rakuten Mobile, and the live customer support is in Japanese, so if you have any issues, it could be hard to find a solution.

Personally, I prefer paying a little more for the eSIM from Holafly since the company offers live chat in English. When I need a physical SIM card, I go with SimOptions because I can order it before my trip, install it, and fix any issues I may have prior to landing in Japan.

What is the best SIM card for Japan?

For us, the best SIM card for traveling to Japan is the Holafly eSIM . It arrives by email as soon as we purchase it, so we can buy it whenever we want, plus it offers high-speed unlimited data.

I’ll tell you more about Holafly as well as the other top SIM cards for Japan below so you can make the best choice for your trip and preferences.

1. Holafly eSIM, the best SIM card for Japan with unlimited data

The Holafly eSIM for Japan is a digital SIM, so after you order your card , you’ll get an email with a QR code that you can scan to start accessing the Internet. This is ideal if your phone doesn’t have a dual card slot, or you are already abroad and need a SIM card.

Keep in mind that to scan the QR code, you’ll need to print it out or send it to your travel companion so you can scan it off their device. Also, I recommend checking your phone’s compatibility here before purchasing the international eSIM .

Looking at the Japanese eSIM card plans for Holafly, you’ll notice that each one includes unlimited data. The shorter-term plans are a bit more expensive compared to other local cards, but Holafly is more convenient, and you can snag a discount on your Holafly purchase by using our link.

2. SimOptions, another one of the best SIM cards for Japan

Another one of the best data SIM cards for Japan is the physical one from SimOptions . I like using SimOptions because I can order the SIM card ahead of time and sort out any issues before my trip. It takes 1-3 business days for the card to arrive at your home, so make sure you order it in advance.

Something else I like about using SimOptions is that I don’t have to waste time and go searching for a local SIM card in Japan once I land. Instead, I can connect to the Internet right away and enjoy the rest of my trip. Also, if your device has a dual SIM card slot, you can simply insert the Japanese SIM card without having to remove your regular card.

SimOptions offers customer support by email and live chat in English, and there are different plans to choose from depending on the length of your trip. The plans have varying amounts of data, so here is a breakdown of the prices:

3. SoftBank SIM, another Japanese SIM card with data

The Japanese SIM card from Softbank is a physical SIM from one of the largest and most prominent communications companies in the country. It’s super popular, so you’ll be able to find it at official retailers, shopping malls, and even supermarkets.

Softbank has 400,000 Wi-Fi points throughout Japan, so you can access the network during your trip for free. Keep in mind that, if you use up the first megabyte of your plan, you can only recharge the card for 14 days afterward. I don’t really see the point of this, but it’s something to consider if you’re using data to work remotely.

Another disadvantage of this card is that you only get 500 MB for 31 days. This is equivalent to about two or three days of navigation, so it’s not a lot of mobile data.

Even so, this is a common prepaid SIM card for Japan , so if you decide to get it, you can purchase it online. You’ll have to register on the website by uploading a photo of your passport and providing some basic personal information.

4. IIJmio, an alternative SIM card for Japan

IIJmio is another option to consider if you’re looking for a local Japanese SIM card . It offers basic mobile data plans for 30 days, and while you’ll only get a few gigabytes, it should be enough for occasional Internet use and Google Maps.

One drawback of this card is that once the data is used up, you can’t recharge it. Rather, you’ll have to buy another prepaid Japanese SIM card . On the other hand, IIJmio offers customer support in Japanese and English, and you’ll receive an origami set with instructions as a gift with your purchase.

5. B-mobile, a popular Japanese SIM card for tourists

If you want to buy a Japanese SIM card online , check out B-mobile . With this service, you can order a SIM online, then pick it up once you land at the airport in Japan. B-mobile can even deliver the card to your hotel.

Regarding its mobile data and network, B-mobile has great coverage throughout the country, so it’s quite convenient for traveling tourists. Also, if you need to extend the duration of your plan or add more data, you can do so without having to buy another SIM card.

Overall, this is a flexible option, although you should keep in mind that B-mobile’s SIM card plans for Japan last from 10 to 20 days and don’t offer unlimited data. So, I only recommend B-mobile if you’re traveling short-term and don’t need too much mobile data.

6. Rakuten Mobile, a good Japanese SIM card for travel

Rakuten Mobile is another company with local SIM cards in Japan . Its 30-day plans offer basic, moderate, and unlimited data consumption, so you should find an option that suits you.

In fact, if you plan on spending a month in Japan, Rakuten Mobile is the cheapest Japanese SIM card , particularly for unlimited data. However, the Internet speed isn’t super strong, so that’s something to consider.

You can buy this SIM card in Japanese shopping malls, as well as in many stores and the airport. Activating it is simple since you just have to insert the SIM into your device to connect to the Internet. Your purchase also includes a free Rakuten Mobile email domain (@rakumail.jp).

7. Sakura Mobile, another SIM card in Japan with unlimited data

The last Japanese SIM card that I recommend is the Sakura Mobile card. This local SIM offers some of the cheapest data plans in the country, and it has customer support in English. Overall, it’s a simple and practical option for those looking for a physical SIM card.

Another benefit of Sakura Mobile is that you can order your card online and pick it up at the airport once you land in Japan. If you’re already in the country, you can purchase it at any official Sakura Mobile store. The only potential issues are that you must unlock your device and check its compatibility with the network here .

Where to buy a SIM card for Japan

Depending on which option you choose, you can buy a Japanese SIM card from the U.S. or from Japan. Personally, I prefer buying mine before the trip, so I feel fully prepared, but there is nothing wrong with purchasing a local SIM at a store or airport in Japan.

Again, we always buy the Holafly eSIM in advance through its website . Then, all we have to do is open our email and scan the QR code. When we need a physical SIM, we order it online through SimOptions, allowing 1-3 business days for it to arrive at our home.

Both of these SIM cards for Japan are easy to install and will allow you to travel with total peace of mind, and with support in your language.

Buy a SIM card in Japan upon arrival

Don’t worry if you’re already traveling or have landed in Japan. You can still get an eSIM for Japan with Holafly , although I recommend checking your device’s compatibility here first. There is also the option of getting a local Japanese SIM card , like the ones I mentioned above. You can find them at several stores, supermarkets, train stations, and airports in Japan.

Just remember that if you opt for a local SIM card, you’ll have to locate a store or retailer, which could take some time. Also, depending on the company, customer support may only be available in Japanese.

Most local cards don’t have unlimited data, so if this is something that’s important to you, I highly recommend getting the Holafly eSIM . Holafly’s Japanese plans range from short-term visits to stays as long as 90 days, and they all have unlimited high-speed data. The closest local competitor is Rakuten Mobile, which has a 30-day plan, unlimited data options, and good rates. However, some travelers have told us that after a few days, the Internet speed slows down significantly.

How to activate a Japanese SIM card for travel

Activating an eSIM or SIM card for travel to Japan is simple. With the Holafly eSIM , just scan the QR code in your email. You’ll have to print it out or send it to a travel companion to scan it.

Hi Ascen Aynat,

How is the connection in rural areas in Japan? I’ll be traveling to Kyushu, Shikoku and Hokkaido and will do quite a bit of hiking and therefore away from urban areas. And in that respect is one option (holafly versus a simcard bought in Japan) better than the other?

Hi Yolanda, The connection in rural Japan is actually pretty good compared to other countries. In my experience, Holafly has always come through with a stable connection, even when we’re hiking or travelling in remote areas.

I’m going to Japan next week and will be there for 10 days. If I get a SIM card for 30 days, can my wife use the same SIM card when she going to Japan in a week after I get back? Or are the cards dedicated to one cell phone when activated? Thanks, Jason

Hi Jason, It depends on the card since some allow data sharing, while others are only for one specific device. Of course, take into account how much data each card includes since if you share it, you’ll run out of data faster. In other words, it could be more cost-effective to purchase separate SIM cards for Japan.

Japan SIM Cards: Detailed Guide

Traveling to Japan and need mobile data? Getting a Japan SIM card for your trip can provide convenient access to maps, translation, and more. With many options: physical SIMs, eSIMs, and short-term data plans, choosing the right Japan SIM card may feel overwhelming. Read on for a full guide on which Japan SIM card or eSIM to know where to buy, and more tips for saving money on data in Japan.

Table of Contents

I. should i buy a new sim card for my japan trip.

For most travelers, a local Japan SIM card is highly recommended among various mobile internet options in Japan :

• Check how much your home carrier will charge per minute/text/MB of data if you use your regular SIM card in Japan. The rates for roaming in Japan may be very expensive.
• Provide affordable access to essential apps like Google Maps, Uber, transit apps, translations, social media, and calling over data.
• Allow you to create a mobile hotspot. This prevents getting lost and allows information access on the go. Depending on hotels and cafes is risky due to spotty WiFi.
• Useful for independent travelers navigating cities flexibly versus relying on tours.

Even tour groups benefit from looking up info separated from guides. With cheap prepaid options, the convenience of data access outweighs minor setup hassles.

Check that your phone is unlocked and supports Japan's main network bands (700/800/1800/2100MHz) before purchasing a local SIM.

Make sure to obtain a data-only SIM due to regulations for foreigners buying voice SIMs in Japan.

II. Japan SIM Card Types – Which One is the Best for Tourists?

When purchasing a Japan SIM card, you must first decide whether you need a physical SIM or eSIM. Here are the key differences:

• Physical SIM Card: The traditional plastic chip that inserts into your phone. Physical Japan SIM cards can be picked up at stores and airport kiosks in Japan or shipped internationally before your trip.
• eSIM: A digital SIM embedded into your phone. eSIMs are configured through an app by scanning a QR code. eSIMs are convenient since you don’t have to swap out SIM cards, but availability is limited to newer smartphone models.

Most Japan eSIM providers also require installing profiles before departure instead of allowing in-country activation. However, esimjapan.net has rolled out eSIM support in Japan, allowing easy activation after arrival.

Recommendation : If you want internet access, protect your info, and get local call rates in Japan, use a Japan SIM card. But if your device supports eSIM, go for a Japan eSIM for benefits like no roaming charges, convenience, flexibility, seamless connectivity, easy setup, and future-proof travel plans.

III. How Much Data Is Enough for a Prepaid Tourist SIM Card for Japan?

With a Japan SIM card, one of the most important choices is picking the right data amount during your trip length. Here are some general data usage estimates:

• Light usage: 2-3 GB for up to 1 week
• Medium usage: 3-5 GB for 1-2 weeks
• Heavy usage: 5+ GB for 2-3 weeks

Daily use of maps, social media, photos, light browsing, and messaging would use the estimated data. Streaming video uses significantly more. To conserve data, use WiFi when available and turn off auto-play videos/music. Download offline Google Maps and translate phrases beforehand. However, Japan’s top carriers have great coverage across popular areas so don’t stress limits – easily top up 1-2 GB mid-trip if needed.

Tips : Each user will have a different data usage volume. You can check on the data tracking on your device to know how much data you have used in a month to estimate the data volume you need for your trip. 

IV. How Much Does a Japan SIM Card Cost?

Cost for Japan SIM cards depends on the data amount, validity length, and network:

• Data-only SIM Card: Typically 400-800 yen for 1 GB. 2-3 GB for a week costs around 1,500-2,500 yen ($10.08 – 16.80).
• Voice + Data SIM: Starts around 3,000 yen ($20.16) for minimal data and call rates around 20-30 yen/minute. More expensive than data-only.
• Tourist SIM Card: All-inclusive packages with unlimited data, free calls, and mobile WiFi can cost over 5,000 yen ($33.56) for one week. Offers convenience at a premium.

However, you can find even cheaper SIM card deals like 1-2 GB for under 1,000 yen ($6.72) if you look in the right places and don’t need an unlimited tourist bundle. Overall, a Japan SIM card can realistically be purchased for under 2,000 yen ($13.44) per week including delivery fees.

Some SIM card plans from mobile operators and MVNO that you can refer to for your Japan trips:

V. Japan eSIM – Alternative to Physical SIM Cards

eSIM offers travelers to Japan a cost-effective way to stay connected. With price points similar to physical Japanese SIM cards, Japan eSIM plans provide the same functionality without the hassle of swapping cards.

For comparison, pocket WiFi rentals in Japan typically cost 4000+ yen (~US$26) per week – much more expensive than an individual eSIM with US$8 per week for your phone.

Mobile data prices do vary by provider and plan type, so be sure to check updated sources for the most accurate information. However, in general, eSIM is one of the most affordable options.

Get ahead of the game by purchasing a flexible Japan eSIM plan online from esimjapan.net today . Installation is seamless – simply receive the QR code via email and activate it with no SIM switching needed. An eSIM ensures you can explore Japan freely without blowing your budget on international roaming or public WiFi.

VI. Where to Buy a Japan SIM Card?

1. Buy eSIM Online

There are many reputable online retailers where you can buy a Japan eSIM. Here are a few of the most popular options:

• Mobal – Mobal offers a variety of eSIM plans for Japan, including plans with data and voice calls. They also offer a physical eSIM card that you can pick up at a location in Japan if you don’t have an eSIM-compatible device.

Having the eSIM installed before your trip also ensures smooth connectivity on arrival in Japan. Always check your device supports eSIM before purchasing.

2. Buy a Physical Japan SIM Card

For a physical SIM card, some good options to purchase include:

Carrier stores

SoftBank is one of the major mobile carriers in Japan and their tourist SIM cards can be purchased directly at SoftBank stores for 4500 JPY (~$30.20). Stores are located across major cities.

Convenience stores

Major convenience store chains like Lawson, FamilyMart and Seven-Eleven sell SIM cards from carriers like bMobile, IIJmio and Sakura Mobile. Look for the mobile phone recharge section.

Most major international airports like Haneda Airport (Tokyo) and Kansai Airport (Osaka) have kiosks or stores selling SIM cards upon arrival. This is very convenient for travelers.

IX. Tips for Saving Data for Japan SIM Card

To reduce mobile data usage in Japan, follow these tips to use your cell phone in Japan and your local SIM:

• Connect to free WiFi whenever possible: Look for WiFi at your hotel, cafes, restaurants, and other local businesses. Parks, transit hubs, and shopping centers may also offer free public hotspots.
• Download offline Google Maps: Save detailed offline maps of Tokyo, Kyoto, Osaka, etc on Google Maps before your trip. This allows navigation without consuming mobile data.
• Enable Data Saver: Turn on Data Saver mode on Android or Low Data Mode on iPhone to minimize background data usage. Disable auto-playing videos and music as well.
• Message over apps instead of SMS/calls: Apps like WhatsApp, Facebook Messenger, LINE, and WeChat offer free messaging without using cellular minutes or SMS allowance. Make calls over data as well.
• Batch photo uploads: Upload photos and videos when on WiFi instead of over mobile data. Avoid auto-uploading every shot you take immediately.
• Download language packs: Download Japanese language packs for Google Translate and other apps while on WiFi before your trip. Translating on the go uses less data.
• Turn off roaming: Keep roaming disabled so your SIM card isn’t unintentionally using data outside Japan which often incurs expensive fees.

Following these tips will help you maximize the value of your Japan SIM card data allowance during your trip!

Do I need to unlock my phone to use a Japan SIM card?

Yes, your phone needs to be unlocked to insert and use a Japan SIM card. Contact your home carrier to request an unlock before traveling if your phone is currently locked. iPhones purchased directly from Apple are generally unlocked already.

Can I use mobile hotspot with a Japan SIM card?

Yes, you can enable mobile hotspot (tethering) to share your Japan SIM card’s data allowance with other devices like a laptop, tablet, or second phone. This is useful for WiFi on the go. However, beware of additional hotspot fees on some cheaper plans.

Do Japan SIM cards work in other countries?

No, Japan SIM cards only provide service domestically within Japan and don’t offer international roaming. Switch back to your home SIM or get a separate SIM card when traveling outside Japan.

Can I make calls and text with a data SIM?

You can make voice calls over data apps like WhatsApp, Skype, Facebook Messenger instead of regular calling with a data-only SIM card. Texting requires a SMS/call capable SIM card or using data-based messaging apps.

What’s the best Japan SIM card for long-term travel?

For trips over 2-3 weeks, getting a monthly data plan of 10+ GB or unlimited data on a long-term SIM card can provide the best value compared to short-term prepaid SIMs. Many providers offer 1-12 month contracts.

XI. Conclusion

Getting a local Japan SIM card unlocks connectivity convenience and flexibility for tourists. While prepaid SIM card around 2 GB if great for basic usage of short trips, eSIM is very convenient and flexible. With various Japan SIM card options readily available, there’s no reason to visit Japan without the internet in your pocket.

Best Tourist Sim Cards in Japan in 2024

When traveling in Japan, having a sim card is essential for easy navigation and staying connected.

Access to the internet allows you to find the best restaurants, directions to your accommodation, book a taxi, and share memorable photos with your family on the go.

While roaming is an option, the international fees can quickly escalate, so we recommend getting either an eSim or a local sim card to take advantage of local phone rates.

The good news is that obtaining either option in Japan is incredibly simple, but it’s useful to know which one suits your needs best.

This comprehensive guide provides all the information you need to know about purchasing a sim card in Japan, including current pricing and the most suitable sim card for your specific requirements.

Best sim card in japan for tourists.

Due to the high price of physical sim cards in Japan, I highly recommend purchasing an eSim instead. There are various eSim providers available in Japan, however, I recommend the Airalo Moshi Moshi eSim which offers a variety of data packages at various prices (from 627 JPY for 1GB to 3,600 JPY for 20GB). This allows you to select exactly the amount of data and the duration you require for your specific trip.

I consider purchasing an eSim to be much more convenient than buying a physical sim card when visiting Japan. If you must purchase a sim card in person, for example if your mobile device isn’t eSim compatible, then I would recommend any of SoftBank, B Mobile or Mobal. All three operators are fantastic and have near perfect coverage throughout Japan.

Japan Sim Card Prices

A Tourist Sim Card in Japan costs between 1,650 JPY and 16,500 JPY in September 2024, however, the exact price will often depend on the store you visit and the plan you choose.

Alternatively, an eSim in Japan will cost between $4.50 USD and $26 USD. This, again, depends on how much data you require and which eSim provider you choose.

I generally recommend this Airalo plan for most tourists visiting Japan which includes 5GB of data which is valid for 30 days and costs $11.50 USD.

Japan Sim Card Providers

In Japan, there are several main SIM card providers that offer different services and plans to cater to the diverse needs of consumers. One prominent provider is SoftBank, known for its reliable network coverage and wide range of data plans. They offer competitive rates and various add-ons to suit individual preferences. Another popular option is JapanBmobile, which offers flexible plans that include unlimited data and voice calls, making it a convenient choice for travelers and expats. Lastly, there is Mobal, a reputable provider with an emphasis on simplicity. They offer straightforward plans with no hidden fees and provide bilingual customer support. Overall, these three providers are among the leading choices for reliable and convenient SIM card services in Japan.

SoftBank Japan Tourist Sim

SoftBank Japan is a renowned telecommunications company that offers reliable tourist sim cards in Japan. With convenient access to high-speed internet, travelers can easily navigate through Japan’s vibrant cities and explore hidden gems. SoftBank’s sim cards provide unlimited data usage and nationwide coverage, enabling tourists to stay connected with friends and family, use navigation apps, and share memorable moments on social media platforms. These sim cards can be purchased at designated stores or conveniently rented at airports, making them an essential companion for an unforgettable trip in Japan.

SoftBank Japan Japan Tourist Sim Price

The price of a SoftBank Japan tourist sim card in Japan is 1,650 JPY.

The plan offered by SoftBank Japan stores includes 3GB valid for 31 days.

Bmobile Japan Tourist Sim

Bmobile Japan offers convenient and affordable tourist SIM cards for travelers visiting Japan. Their SIM cards provide unlimited 4G/LTE data and coverage across the country, ensuring fast internet access throughout your trip. With easy activation and no need for a Japanese address, Bmobile’s SIM cards are hassle-free and suitable for short-term visitors. Stay connected and navigate with ease using Bmobile Japan’s reliable tourist SIM cards.

Bmobile Japan Japan Tourist Sim Price

The price of a Bmobile Japan tourist sim card in Japan is either 1,980 JPY or 2,970 JPY depending on duration and data required.

The plan offered by Bmobile Japan stores offers 5GB and 7GB data valid for 10 or 21 days.

Mobal Tourist Sim

Mobal is a well-known provider of tourist SIM cards in Japan. Their SIM cards offer reliable and fast internet connection, allowing visitors to stay connected during their travels. With excellent coverage throughout Japan, including major cities and rural areas, Mobal ensures uninterrupted communication. These SIM cards also include generous data allowances for browsing, social media sharing, and streaming.

Mobal Japan Tourist Sim Price

The price of a Mobal tourist sim card in Japan is between 3,990 JPY and 16,500 JPY..

The plan offered by Mobal stores includes Unlimited data valid for 8 to 90 days.

How to Get a Sim Card in Japan

Identify mobile providers: SoftBank Japan, Bmobile Japan and Mobal are your best options in Japan.

Find your nearest store: Locate a store or retailer by searching on Google Maps for your nearest store or asking at your hotel reception. I’ve never had issues finding a store as they can usually be found in major cities, shopping centers, or tourist areas. If possible, I always recommend to to avoid airports and head in to an official store in the city.

Bring the necessary documents: It is always a good idea to carry your passport or identification documents for sim card registration purposes. We’ve found most providers will need to confirm your identity to provide a sim card and it can be a major hassle to head to a store only to have to come back again later with your passport.

Choose your plan: Either request the plan you are after or consult with the staff in the store to select the right plan for you. My recommendations at the beginning of this guide are a good starting point, but the staff will usually be able to suggest the best option.

Pay and activate your card: Pay for the SIM card and plan, and the staff will activate it for you.

Test: It’s always a good idea to check that you can access the internet before you leave the store. I always search for something on Google then refresh my Instagram feed to check it’s working fine.

Where to Get a Sim Card in Japan

At the airport.

Buying a prepaid sim card for Japan at the airport is usually considered the most convenient option for travellers arriving by plane.

However, airport stores selling sim cards are almost guaranteed to charge inflated prices, so if you are a cost-conscious traveller then you should definitely buy your sim card from a store in the city center.

In addition to this, we would argue that buying physical sim cards at all aren’t particularly convenient now that most people use esim compatible phones. If you are looking for the most convenient option, then buying an esim before you arrive or with the airport wifi is much easier and will save you having to queue up or communicate with staff.

If you must purchase a sim card at the airport in Japan then you will be in luck. All major international airports in Japan have stores selling sim cards. Despite the prices being higher than normal, the staff are knowledgable and will be able to get you set up with the correct sim card relatively quickly.

If you want to avoid the inflated sim card prices you’ll find at the airport and your phone isn’t esim compatible, then you’re going to need to head in to a store to buy your sim card.

I recommend visiting one of the official retail stores of the mobile internet operators such as SoftBank Japan, Bmobile Japan and Mobal. Your best option is to enter their names into Google Maps and find the branch closest to your hotel or accommodation. Typically the staff in the official stores in Japan are knowledgable and helpful which means you can ensure you’ll walk away with a functioning sim card.

Despite this, it’s always a good idea to check your internet is working before you leave the store by loading a Google search results page and your preferred social media app. You should also ensure you always bring your passport with you when purchasing a sim card in case they need to register it.

If you like to be prepared and would prefer to arrive in Japan with your sim card all sorted and your phone ready to connect to the internet immediately then you should look into purchasing a sim card online.

The first option is to buy your sim card in advance via SimOptions, which is a company that will prepare and ship a sim card directly to your door. It’s a reliable and effective service, but with the invention of eSims it’s becoming obsolete.

The better option is to purchase an eSim online. We’ve written more on that below!

An eSim is a digital version of a traditional sim card and is most likely the future of connectivity for mobile devices. The convenience of no longer visiting a store, handing over your passport and purchasing a physical sim card is quickly making physical sim cards obsolete in favour of eSims.

We recommend Airalo’s eSim when travelling to Japan. The Airalo Japan eSim offers fast internet speeds, wide coverage and extremely competitive prices making it a far more compelling option than purchasing a physical sim card from any of the local sim card providers.

In order to get set up with an Airalo eSim , all you need to do is visit Airalo here and purchase the eSim online (the $11.50 USD plan is suitable for most travellers). Once you’ve purchased the sim card Airalo will email you instructions and a QR code. Following these instructions should take just a couple of minutes, then you’ll have a sim card in Japan without having to venture outside.

Airalo Japan

Our preferred eSim provider in Japan is Airalo . We used them, alongside a local sim card on another device, for our most recent trip to Japan and found the service to be equal to the local sim card but without the hassle of acquiring a sim card in a store.

Airalo’s Japan eSim uses the AU Japan by KDDI and SoftBank Japan networks to provide data and connect users to the internet. You can expect very good coverage and reliability with the AU Japan by KDDI and SoftBank Japan networksnetwork as they are amongst the best mobile internet operators in Japan.

Here are the plans and prices for Airalo’s Japan eSim:

1GB data valid for 7 days – Price: $4.50 USD 2GB data valid for 15 days – Price: $6.50 USD 3GB data valid for 30 days – Price: $8.50 USD 5GB data valid for 30 days – Price: $11.5 USD 10GB data valid for 30 days – Price: $18 USD 20GB data valid for 30 days – Price: $26 USD

For most travellers we recommend the 5GB data plan for $11.50 USD which is valid for 30 days. Some travellers may prefer a larger plan, whilst travellers visiting for just a couple of days may be fine with a smaller plan.

Holafly Japan

An alternative eSim provider we can recommend is Holafly.

Holafly’s eSim is a suitable option for travellers who require large amounts of data, such as digital nomads and people who work online while they travel. All of Holafly’s Japan eSims offer unlimited data.

Holafly’s Japan eSim uses the KDDInetwork to provide data and connect users to the internet. This network will provide reliable speeds and coverage while in Japan

Here are the plans and prices for Holafly’s Japan eSim:

Unlimited data valid for 5 days – Price: $19 USD Unlimited data valid for 7 days – Price: $27 USD Unlimited data valid for 10 days – Price: $34 USD Unlimited data valid for 15 days – Price: $47 USD Unlimited data valid for 20 days – Price: $54 USD Unlimited data valid for 30 days – Price: $64 USD Unlimited data valid for 60 days – Price: $87 USD

What is an eSim?

The eSIM, or embedded SIM, is a digital replacement for physical SIM cards found in devices like smartphones, tablets, and smartwatches. Unlike traditional SIM cards, the eSIM is built into the device and does not require physical insertion or removal.

Instead, the eSIM is seamlessly integrated within the device’s hardware and can be remotely activated and programmed by a mobile network operator. This allows users to easily switch between different mobile networks or plans without the need to physically swap out SIM cards.

The eSIM technology offers numerous benefits, such as convenience, flexibility, and user-friendliness, particularly for frequent travelers or individuals who regularly switch mobile networks or travel internationally. It eliminates the hassle of purchasing and inserting physical SIM cards, making it more convenient to manage multiple mobile connections on a single device.

To activate an eSIM, users can either scan a QR code provided by their mobile network operator or manually input the activation details. Once activated, the device can connect to the chosen mobile network and access voice, data, and messaging services, just like with a traditional SIM card.

Why Use an eSim?

There are several reasons why using an eSIM can be beneficial. Firstly, it provides convenience by eliminating the need to physically insert or remove a SIM card when switching networks or plans. This is especially useful for frequent travelers who may need to use different SIM cards in different countries.

Secondly, eSIM allows for dual SIM functionality, meaning you can have two active mobile numbers on the same device. This is great for separating personal and work numbers or managing multiple phone lines.

Additionally, eSIMs save space as they are embedded within the device, eliminating the need for a physical SIM card slot. This allows manufacturers to make devices smaller or use the extra space for other components.

Furthermore, eSIMs enable remote provisioning, allowing for activation and management of mobile plans over the air. This means you can switch to a new plan without needing a physical SIM card or visiting a store, offering greater flexibility and convenience.

Lastly, by using an eSIM-compatible device, you ensure future-proofing as more mobile networks and service providers support eSIMs. This allows you to take advantage of new services and offerings as they become available.

Overall, eSIM technology provides flexibility, convenience, and future-proofing for mobile connectivity, making it a compelling choice for many users.

eSim Supported Phones

eSIM technology is becoming increasingly popular and is supported by a growing number of smartphones and other devices. Here are some examples of eSIM-compatible phones:

Apple iPhone series (iPhone 11, iPhone 12, iPhone 13, etc.): Apple was one of the early adopters of eSIM technology and offers support for eSIM on various iPhone models.

Google Pixel series (Pixel 3, Pixel 4, Pixel 5, etc.): Google’s Pixel smartphones also support eSIM functionality, allowing users to activate and use eSIMs.

Samsung Galaxy series (Galaxy S22, Galaxy Note 20, etc.): Many of Samsung’s flagship devices now come with eSIM support, enabling users to utilize eSIM technology.

OnePlus devices (OnePlus 7, OnePlus 8, etc.): OnePlus has included eSIM support in some of its smartphone models, offering users the flexibility of using eSIMs.

Motorola Razr (2020): The latest iteration of the iconic Motorola Razr features eSIM compatibility, enabling users to use eSIMs for cellular connectivity.

These are just a few examples, and the list of eSIM-compatible phones continues to expand as more manufacturers embrace this technology. There’s a very strong chance your phone supports eSims so if you’re unsure we recommend looking it up on our list of eSim supported phones .

How to Use an eSim

Using an eSim is new for many travellers, however, the good news is it’s surprisingly easy to get set up – even for the technologically challenged!

Here’s a general guide on how to use an eSIM:

Check eSIM Compatibility: Ensure that your device supports eSIM functionality. Many newer smartphones, smartwatches, tablets, and other devices are eSIM compatible including all iPhones produced since 2018.

Obtain an eSIM: There are multiple ways to acquire an eSIM. You can purchase an eSIM online from a provider like Airalo (which we recommend) or directly from a mobile network operator. Some devices also allow you to scan a QR code provided by your carrier to download the eSIM profile.

Activate the eSIM: Your eSim provider will send you instructions to activate the sim. This will usually involve scanning a QR code, entering an activation code, or downloading the eSIM profile directly onto your device.

Set up the eSIM: Once activated, your device will guide you through the eSIM setup process. This typically involves selecting the eSIM as your preferred mobile plan, configuring settings like data roaming, and entering any necessary authentication details.

Enjoy the Connection: Once the eSIM is set up, you can use it as you would with a physical SIM card. Make calls, send messages, browse the internet, and use data services as needed. You can also switch between eSIM profiles if you have multiple eSIMs installed on your device.

Japan Here We Come

The Best SIM Cards for travel to Japan

Here we share the best tourist SIM cards to stay connected in Japan.

We have traveled through the country many times. The very first time we often found a “Handy” phone in our hotel room. A telephone that you could use during your stay. But that time is over.

You now have to find a solution yourself if you want to be connected. And that is really recommended. Although there is free internet in quite a few places, and even apps that make it easy to connect to free WiFi hotspots, there are still many places where you will have to have a data subscription if you want to use the internet.

And we always use the internet a lot while in Japan.  We use our smartphones to navigate the vast cities, to find recommended places to eat and cat cafés, and to look up the train and metro schedules.

We also like to browse around the shops where you can find gadgets and care products that we don’t know about. But also there we often have to fall back on our smartphones to discover what it is exactly or how it works.

Roaming tariffs can be insane, they certainly are in our case, and local SIMs aren’t expensive at all.

Below is an overview of the physical SIMs that you can order online and pick up at the airport, eSIMs, and other ways to stay connected in Japan.

We have already used both a physical SIM and an e-SIM, so we also explain how this works.

Don’t worry if you’re reading this article on the day of departure or when you’re already in Japan.  You can also buy a SIM at the airport or in an electronics store in Japan.  I will guide you on how to do this further down in this article.

And, if your phone supports it, you can of course opt for an eSIM at any time.

Regular Japan Traveler SIM vs eSIM

During our first trips we always used a regular SIM that we pre-ordered online and picked up at the airport upon arrival. Very convenient and everything always went very smoothly. Below we explain in more detail how this works.

However, we both recently switched to a cell phone that supports eSIMs and thus we used an eSIM for our last trip.

It was the very first time we used such an eSIM, so we were a little nervous about whether everything would run smoothly and the technology would not let us down.

That stress seemed completely unwarranted. All steps on how to install and activate the SIM were neatly explained.

What’s our verdict?

Both worked equally well when considering connectivity and speed. If your phone supports eSIMs, I would opt for an eSIM for Japan. It offers the advantage that you do not have to change SIM cards and that you can, at all times, easily switch from your regular SIM to the Japan tourist eSIM.

We like the Airalo’s eSIMs for their ease of installation and Mobal eSIMs for Japan for their excellent selection of data packages.

We have a full guide on eSIMs for Japan .

But no problem if your phone does not support eSIMs. There are plenty of alternatives that you can order online and quickly pick up at the airport upon arrival. Below is an overview.

Japan Tourist SIM cards – The top choices

The list of Japan traveler SIM cards seems endless. We found no less than 30 different options when we were looking to buy a SIM for our last trip.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

Below is an overview of our top picks.

Sakura Mobile

Sakura is a Japanese company that offers wireless services for all who are visiting Japan.

Buying a SIM card in Japan

If you’re already in Japan when you’re reading this there’s no need to worry. 

Believe it or not, we arrived unprepared the very first time ourselves. It’s relatively easy to buy a SIM card in Japan. We then bought an IIJmio SIM in a Ydodobashi Camera store.

Here are your options for when you’re in Japan.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport (see here and here ).  You can also find SIM cards in the BlueSky shops .

The sales points from the operators will likely be able to better assist you in English and may give better advice. 

In the cities

Another option to buy a SIM card in Japan is to head to one of the BIC Camera or Yodobashi Camera stores. 

They sell various prepaid SIM cards for Japan tourists.  We used the IIJmio SIM during our very first trip to the country. This SIM comes with a brief explanation of how to install it. You can also find all the settings on their website.

The data limit of 1GB is pretty limited but you can buy coupons to recharge the SIM.

Usually, at least some of the staff will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they do at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is.

But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

There are several Yodobashi and BIC Camera stores. At your hotel they should be able to give directions to the nearest one or you can use Google maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend. They have so many electronic gadgets and gizmos in Japan, all things that you won’t find elsewhere. (I still don’t understand why those luxury toilets can hardly be found anywhere else in the world)

But you can also compare the various options from the comfort of your hotel room and order a SIM online. 

An eSIM is the first thing that comes to mind. You can compare the alternatives, buy the one that suits you and install and activate it. All in a matter of minutes.

If your phone doesn’t support eSIMs you can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

Alternative options to stay connected

You don’t want the hassle of changing SIM cards? No problem, in that case you can opt for one of the following alternatives.

Free WiFi in Japan

A lot of places offer free WiFi. You find it in coffee shops (Starbucks) Metro Stations (Tokyo Metro) and JR train stations.

It used to be quite a hassle to repeatedly connect to these networks but there is now an app, Japan WiFi Auto-Connect , that will automatically connect to certain public WiFi hotspots. For security reasons not to all public WiFi hotspots, but only those managed by trusted corporations or public authorities.

It worked perfect for 90% of the time during our last trips. When I walked into a metro station or train station I was usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple.

Thanks to this app, among other things, it has become much easier to make use of free WiFi hotspots.

During our first trips to Japan, we had to fill out a form each time we wanted to use a hot spot, only to realize that the WiFi didn’t work in the end. Now, free WiFi is much more reliable for foreigners.

However, I recommend not relying solely on it, just as we don’t. Hotspots become scarcer as you leave the major cities. Even in the capital, I find it convenient to have internet access at all times and be able to look something up when it crosses my mind, not just when I’m at a hotspot.

It’s a matter of convenience, but for the small price of a SIM card, I think it’s worth it.

Here’s an overview of the WiFi hotspots in Tokyo .

Pocket WiFi Devices

The main advantage of using a pocket WiFi device is that you don’t need to switch the SIM in your phone. You also don’t need to change any of the settings of your phone. You only need to connect to the WiFi signal broadcasted by your WiFi Device.

Do make sure that your data connection is disabled to avoid any nasty data roaming fees.

And if you’re traveling with your family, or with friends, you can all share the same WiFi signal.

As your SIM remains in your phone this also means that friends, family, work relations, and anybody else who has your phone number can reach you as if you were home.

A disadvantage of a pocket WiFi device is that it is one extra device that you need to carry around and that you will need to charge on a daily basis if you use it frequently.

If your phone supports eSIMs , we think that is the ideal solution. Since we got our new phone, with support for eSIM, we have always opted for an eSIM.

Your regular SIM remains in the phone. You will remain reachable on the known number and you can use data via your local eSIM. So the best of both worlds.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. It used to be a virtual operator but it is now building out its own network. Today it covers about 94% of the population. Their customer relations team only speaks Japanese.

There are several other providers but these typically piggyback on the network of these 3 majors to offer their services.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second, they are not far behind, and they still cover 99% of Japan (population-based).

Au by KDDI is seen as the least reliable network of the major players.  They do well in terms of coverage but their reception is not as good inside buildings or underground due to the frequencies they’re using.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There are many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

Enjoy Japan!

The Best eSIMs for Visiting Japan — Tested and Compared

The eSIM market has exploded in recent years. With so many options out there it can be hard to pick the best one for your trip to Japan. Fear not! We’ve done the legwork for you. From short stays to long and everything in between, here’s some of our picks for Japan eSIM packages, tested and compared.

Best eSIM for light data usage -->

Japan eSIMs tested and compared

First, here’s a summary of what we found when we tested the eSIMs (updated September 2024): If you’re curious, here’s how we tested the Japan eSIMs .

What exactly is an eSIM?

It’s a virtual SIM that you can download and install onto your phone directly, so no more fiddly physical SIM cards. Most phones released since 2019 can use an eSIM, with Apple’s US iPhone 14 and 15 being eSIM only. eSIMs are convenient when you want to change your carrier, such as when abroad, as you can connect to a new provider in seconds without removing your existing physical SIM card.

Japan eSIMs for tourists and short-term visitors

Here’s a quick overview of some of the Japan eSIM options for your trip. This is not an exhaustive list; just an introduction to some of the main players in the market.

Best eSIMs for short trips

These are the providers with a big range of shorter plans:

eSIM Japan: Flexibility from short stays to unlimited data

eSIM Japan has among the most extensive plans for travelers to Japan. Their plans are broken into three basic types: Unlimited data 3–30 days, 5G Unlimited Max 3–15 days, and fixed-data 7–30 day plans. The unlimited data 3–30 day plans have 1GB per day and 2GB per day options, and you can select from nine different trip lengths. All of their plans score fairly highly in terms of affordability and speed.

Installation

When we ordered the 2GB/day Japan Unlimited Pro eSIM, a QR code arrived in our inbox immediately. From purchase to use, it took less than 15 minutes.

The plan begins when you scan the code and install the eSIM. Plans have a set time limit and a data limit (3GB, 5GB, 10GB, or unlimited), so you can choose a plan that works for the length of your trip.

Performance

eSIM Japan is provided by China Mobile Hong Kong but roams to Japan’s KDDI au network (you’ll need to enable roaming to use it). Despite roaming, it was fairly fast, with an average download speed of 38.27Mbps. Websites loaded in a flash, and video calling and streaming were smooth, with no lags.

Note: If you are in Hong Kong or Taiwan, you’ll need to use real-name registration. Otherwise, no signup is required.

World eSIM: Reliable speeds and connectivity

World eSIM is brought to you by Vision Inc. — the folks behind well-known travel Wi-Fi name Ninja Wifi . World eSIM provides three different types of packages – unlimited, fixed, and daily data plans. Unlimited plans range from 5–30 days, daily data plans are 3–15 days, and fixed data plans include 5, 10, and 20GB options. Their eSIMs ranked reasonably high in our speed tests, and their plans are affordable per gigabyte.

Getting our eSIM was straightforward. After signing up on the World eSIM website, we paid and received a QR code instantly in our email. A quick scan, and we were ready to go.

Download speeds averaged 99.15Mbps, and streaming was smooth. During our test, we found that this was one of the best eSIMs for video calling. Overall, it’s a solid choice.

Best eSIMs for long trips

When you want a big range of options for 30-day eSIMs and bigger data caps:

Mobal eSIMs: Big data limits and voice + data plans

Mobal’s short-term data-only plans come in 8-, 16-, and 31-day durations, with data limits ranging from 3–100GB. The short-term voice + data sims are also available for 30, 60, and 90 days, although data limits on these plans are capped at 7GB per calendar month. If you’re after a more long-term voice + data option, plans are also available with monthly fees for 1, 5, 10, or 30GB of data per month (see below). 

Activating the data SIMs takes about 15 minutes. After 5 minutes, we received an email with a link to their service website. This led us to a page where we waited for our eSIM QR code to be ready for another 10 minutes.

In terms of performance, Mobal is about the middle of the pack, at an average of 24.76Mbps. Websites loaded quickly, and video calling was fairly smooth. Overall, it’s a solid, reliable eSIM.

Mobal long-term voice + data eSIM for Japan

There is also a voice + data eSIM , which has an initial fee of ¥ 2,970 . When you activate your eSIM, you’ll need to choose a monthly plan, ranging from 1GB/month for ¥ 1,650 to 30GB/month for ¥ 4,378 . There is no minimum contract period or cancellation fees, making it a viable choice for travelers and residents alike. You get a real Japanese phone number with this eSIM. We tested out the 7GB plan.

Note: Due to regulations in Japan, the voice + data eSIM cannot be emailed to customers; your access code will need to be posted to your residence overseas or otherwise picked up in person in Japan. You must apply in advance, upload an ID document, and wait for a delivery. Once you get your package in the mail, you need to activate your Mobal eSIM on the Mobal website. You’ll enter a 32-digit EID, then wait for Mobal to activate your eSIM and provision your new Japanese phone number. Technical support is available via email and a web form, though most questions can usually be solved by having a peek at Mobal’s FAQs page.

Saily: Excellent value for 20GB

Saily offers straightforward eSIM plans in 7- and 30-day options. The 7-day option offers 1GB of data, while the 30-day options range from 3 to 20GB. Price-wise, the 20GB Saily eSIM for Japan can’t really be beaten. Saily comes from the well-established tech company NordVPN , and uses UK network 1GLOBAL, with local roaming via NTT Docomo.

Our Saily eSIM was ready for download instantly, and activation was foolproof with their dedicated Android/iOS app, which walks you through the set-up process.

Speed-wise, Saily performed well with a strong 5G signal at most of our testing locations; video streaming and calls were flawless.

Ubigi: Fast speeds for long stays

Ubigi is a global eSIM provider currently offering eSIMs for over 200 destinations. A relatively new name in the Japanese eSIM market, they nonetheless have plans to cover most needs. From economical single-day 500MB plans for ¥ 390 to beefy month-long plans with unlimited data for US$ 74.00 , there’s something for all travelers.

Ordering from Ubigi is a snap. Once we paid, a QR code was emailed to us in seconds. One quick scan, and we were ready to go. Like most others on this list, Ubigi works with NTT Docomo for reliable coverage across Japan. The company behind Ubigi is Transatel, which is actually owned by NTT.

We tried the 3GB Ubigi eSIM. In our testing, we experienced average speeds of 73.72Mbps and web pages loaded in a flash. YouTube playback was smooth with no buffering, and our video calls were lag-free. Ubigi’s excellent quality and speed make it a strong contender at this price point.

Airalo: Lightning speeds from a trusted brand

Special offer: Order through our link and get 10% off . The discount is automatically applied at checkout.

If you’re in the market for speed, Airalo isn’t going to play games with you. Airalo eSIMs roam to both KDDI au and SoftBank, two of Japan’s major carriers, offering dependable data on the go. Their Moshi Moshi eSIM line of eSIMs has 7, 15, and 30-day packages. The 7-day package is the bare minimum, with only 1GB of data for US$ 4.50 . The 15-day plan offers 2GB; at the upper end, the 30-day plans come in 3, 5, 10, and 20GB increments. For those of you who burn through your data, that 20GB package will set you back US$ 26.00 .

Getting the Airalo eSIM took no time at all. We signed up for the 2GB/15-day Moshi Moshi eSIM, and after paying, we were immediately taken to a page with our eSIM QR code waiting. We were 100% good to go within 15 minutes. Note that sign-up is required for this eSIM.

When it came to our speed test, this eSIM left all of its competitors in the dust. Our testing had a lightning-fast average download speed of 141.61Mbps. Websites loaded almost instantly, and YouTube videos didn’t stop to buffer once. Even our awkward video calls didn’t make this eSIM break a sweat. If you’re the sort of person who works your data to the bone, Airalo is a good choice.

Best eSIM for light data use

Gigsky japan esim: fast speeds and reliable connectivity.

Best eSIM for families and groups

For sharing data with your travel squad:

Flexiroam Japan eSIM: Great for groups

Flexiroam offers six fixed-data plans and six unlimited data plans across their Japan eSIM range. Fixed data plans include four 30-day eSIMS of various data limits and two shorter 7-and 15-day options. Flexiroam’s unlimited plans are staggered from 5 days up to 30 days. The Japan eSIMS roam to all of Japan’s major networks, and their fixed-data plans offer the option to distribute data to friends and family and roll your data over to additional plans. 

You’ll need to create an account to purchase and install your eSIM. While it’s not a requirement, we found it was easiest to buy through the Flexiroam app. Through the app or the website, you choose your trip destination, usage (fixed or unlimited data), and trip duration, and you’ll be presented with the available options. From there, select the plan you want and enter your payment details.

You’ll receive a QR code and instructions via email to set up your eSIM. You can install your eSIM using the QR code or through the app, but we found the QR code easier. Depending on your phone, you may need to update the APN settings for the eSIM to work. As per the website, the eSIM can take around 15 minutes to connect to a local network for the first time after installation. 

Flexiroam’s website says that it’s eSIMs automatically connect to the strongest signal from the available local operators. While its website doesn’t transparently list its partner networks in Japan, we were able to manually connect to two of Japan’s major network operators (Docomo, NTT, and Softbank) during our tests. In terms of speed, Flexiroam ranked around the middle of the pack during our tests.

Best eSIM for flexible plans

When you want heaps of options for days, data, and top-ups:

Sakura Mobile: Trusted local Japan provider

An established SIM and Wi-Fi provider popular with both short and long-term visitors to Japan, Sakura Mobile also has a line of eSIMs. A big selling point of Sakura’s Travel eSIMs is their flexibility. Short-term eSIMs are available from 1 all the way up to 90 days with a combination of unlimited and fixed-data options. If you’re after a semi-permanent option, Sakura offers long-term data-only and voice + data eSIMs at 5, 25, and 40GB per month.

We tested the 3-day, 3GB data-only eSIM, which cost ¥ 2,750 . There was no option to install it directly through the Sakura Mobile website; the QR code and instructions were emailed to us. The user interface was clunky, but the eSIM was set up in under 15 minutes. We didn’t need to activate roaming to use it.

In terms of performance, Sakura Mobile’s download speeds averaged 84.46Mbps, although they varied significantly across test platforms. Video playback and calling were smooth, though, and we were satisfied with the overall performance.

Jetpac: Good price and performance

Esims with unlimited data.

From the names mentioned above, eSIM Japan, Ubigi, Sakura, World eSIM and Flexiroam, all offer unlimited data plans.

eSIM companies are increasingly offering different types of unlimited plans for heavy data users such as business travelers and remote workers. For a breakdown of some of the unlimited providers out there, see our dedicated comparison of Japan eSIMs with unlimited and nearly unlimited data .

Japan eSIM FAQs

How much data do i need.

Average users in their home country will use around 5GB per week. When you’re at home, though, you’re probably connected to Wi-Fi for most of the day. When traveling, chances are you’re connected to Wi-Fi a lot less. You’re relying on data for things like maps and translation, browsing for things to do and places to go.

500MB – 1GB per day might be enough if you’re just using your data for things like maps and instant messaging while you’re out. But if you’re on your phone during a long Shinkansen trip, using data for work, tethering, or spending a lot of time on social media, you might want to consider the higher end of the spectrum.

If you’re worried about going over your daily data limits, consider downloading offline maps and saving most of your heavy data usage for when you’re on Wi-Fi. Also, consider setting a data warning on your phone. Alternatively, consider plans that offer data top-ups. 

Is my phone eSIM compatible?

This is important to check before handing over your money! While most phones made in the last few years or so will have eSIM functionality, not all phones will be unlocked. If you purchased your phone outright, chances are it’s unlocked. If, on the other hand, your phone came under a contract with a network provider, chances are your phone will be locked by that provider.

Checking whether your phone is unlocked is pretty quick and easy. If you discover that your phone is locked, check with your service provider to see if it’s possible to unlock it before buying an eSIM. Alternatively, if you’re traveling with family or a small group, consider renting a pocket Wi-Fi device to share.

What’s the best eSIM for skiing or snowboarding in Japan?

Two things to consider when on a ski trip in Japan are connectivity and the ability to make emergency calls . If you’re heading to Nagano, Hokkaido, or Niseko, then you’re going to want a service that has reliable connectivity in remote areas.

NTT Docomo is often regarded as the best provider in regional areas because of its overall network coverage — so an eSIM that connects to Docomo’s network would be a good choice when heading to the snow. Secondly. if you prefer not to rely on apps like Skype for emergency voice calls, look for a provider that offers a combined voice + data package, like Mobal . If you’re in an emrgency in Japan, the number to dial is 119.

What’s a Fair Usage Policy?

This is probably something you’ll see pop up quite a bit while researching eSIMs, and it’s worth noting, especially if you’re looking at unlimited data options. Many “unlimited data” plans are actually capped at around 2 to 5GB per day, with speeds throttled after you hit the daily limit.

In slightly rarer cases, providers will offer “truly unlimited” plans with no apparent daily data limits. However, remember that these may ultimately be bound by Japan’s nationwide Fair Usage Policy (FUP). Japan’s FUP basically says that to provide equal internet access to all network users, everyone should use the internet reasonably. If a user is deemed to be using excessive data, networks may implement the FUP and throttle their internet speeds. This means that although you might have purchased a truly unlimited data plan, be careful of using much more than 2 or 3GB per day, as there’s a chance that your speeds will slow to a grinding halt until at least the next day.

Which network offers the best coverage in Japan?

In general, NTT Docomo is said to have the most infrastructure nationally. Still, there isn’t a clear objective winner regarding overall quality between the three primary players, Docomo, AU, and Softbank.

A recent study awarded Docomo the best in general availability, but AU and Softbank both lead in 5G coverage. Similarly, although Docomo is said to have the largest network, it also has the biggest user base. This means that it may be slower in crowded areas but may perform stronger in more rural areas.

Which Japan eSIM is the fastest?

Airalo scored the highest in our speed tests by a solid margin at the time of writing, followed by Ubigi and World eSIM. Airalo runs on both Softbank and KDDI AU networks. Ubigi runs on NTT Docomo and World eSIM runs on Softbank. 

How easy is it to switch between eSIM plans during a trip?

If you have multiple eSIMs already installed, switching between different SIMs is quick and easy. If you’d prefer to keep things simple, some eSIM providers offer regional SIMs that cover multiple countries, such as Japan, Korea, and Taiwan on one SIM. 

Which is better for your Japan trip: An eSIM or a physical SIM card?

Even with more providers arriving on the scene, the options with physical SIMs are still superior to what you can get with eSIMs. For example, only one of the eSIMs listed here includes a Japanese phone number with calling ability (that’s Mobal ).

If you’d like something a little more inconvenient but with better options, check out our guide to prepaid SIM cards for travel to Japan . We also recommend taking a look at mobile Wi-Fi rental for Japan to compare connectivity options.

What’s the difference between international roaming eSIMs and local eSIMs?

Essentially, there are two types of eSIMs — eSIMs provided by foreign companies that roam to the local network, and eSIMs that are native to the country you’re in. Many companies that offer Japanese eSIMs are the former, essentially foreign eSIMs with agreements with local carriers like Docomo or KDDI that allow them to connect to their networks.

In terms of coverage, there aren’t any significant differences — foreign eSIMs will be roaming to the same networks that local providers use. There are some potential downsides to foreign eSIMs, though, including battery drainage caused by roaming, and slower speeds caused by latency. In most cases, these issues won’t be entirely noticeable, but may be things to consider when choosing your eSIM.

How we tested our eSIMs

We regularly test the providers listed above and report the average speeds over time based on all the tests. To perform the tests, we purchase an eSIM from each provider — the same as any customer would, and use the Ookla speed testing app. This app does a standard test to measure upload, download, and latency.

Speed results can vary based on several factors, so to get fair and realistic test results, we do the following:

• For each round of testing, we do tests from 3-5 different locations around the Tokyo greater area
• At each location, we perform the test twice for each provider and use the same model of smartphone
• We do a round of tests every 2-3 months, and so keep an average of the results from each provider over time
• We also do some random spot testing for general usage, e.g., doom scrolling social media, making short video calls to look for lag, etc.

If there are some anomalous results, we may retest the eSIMs on the following day, at a different location in Tokyo, to compare results. For example, on our very first round of testing, Mobal and Sakura Mobile experienced severe throttling on the initial test day. This was because we’d burnt through the daily allowance when figuring out how to do the tests! We could repeat the tests the next day when the allowance had reset.

Some eSIMs had to be run on the same device, meaning that not all tests were simultaneous. Our testing method isn’t perfect, but it does give us a good idea of the different eSIMs’ performance. We excluded some eSIMs from the article where we had concerns about the ordering process, performance, or pricing.

A word on speed tests: We strongly recommend not running speed tests with your eSIM, as they BURN through data. A single test could use 300MB or more!

While we do our best to ensure everything is correct, information is subject to change. Prices are approximate. This post was first published in October 2020 and was last updated by Patrick Balfe in September 2024.

Price Plans

Select Start Date and End Date to see your price options (Prices below do not include tax)

• * Unlimited data plans come with a Fair Usage Policy (FUP) to manage network resources. This means you won't be disconnected based on usage, however, your speed will be limited after using 3 GB of data.

For plans without daily limits (FUP), please check our available Fixed Data Plans .

Unlimited data (FUP*) 5 days

Unlimited data (fup*) 8 days, unlimited data (fup*) 12 days, unlimited data (fup*) 15 days, unlimited data (fup*) 21 days, unlimited data (fup*) 30 days, unlimited data (fup*) 45 days (30 days + 15 days), unlimited data (fup*) 60 days (30 days + 30 days), unlimited data (fup*) 90 days (30 days + 30 days + 30 days).

• * Unlimited data plans come with a Fair Usage Policy (FUP) to manage network resources. This means you won't be disconnected based on usage, however, your speed will be limited after using 2 GB of data.

What can I do in 1 day with FUP?

The high-speed data available is a daily average of around 2 GB for the travel SIM card and 3 GB for eSIMs. If usage exceeds this, speeds may drop to 200 Kbps without notice. To restore speeds, reduce your daily data usage to a few hundred MB for a few days. For typical travel needs, 1 or 2 GB of data per day should be more than sufficient, unless you plan on streaming videos or movies frequently. Note: The TRAVEL SIM card is for travelers and not suitable for extended video streaming, conferencing, or large downloads. For such needs, please contact us about our business plan without FUP.

How to order and activate eSIM

First, book your eSIM by choosing your usage dates in the calendar above.

2. Check e-mail

An e-mail will be sent to you right after your order is completed. Please access the QR code from the link inside the e-mail.

3. Activate

Use QR code and install the eSIM. You will then be able to use it immediately. * The day you install our eSIM will be the day that usage period starts.

2. Shipment

We ship according to your pick up date (usually, it’s 3 days prior pick up date). Your item will be delivered a night before you arrive at your pick up place.

How to activate

A WiFi connection is required when activating your eSIM.

Reviews from customers

To manage network resources, unlimited data plans are managed by a Fair Usage Policy (FUP). In wireless internet services, unlimited data means you will not be disconnected based on your usage or the amount of data transferred.

We do our best to provide our customers with large amounts of data that they can comfortably use while in Japan. However, depending on the carrier’s decision, the overuse of mobile communication will affect the usage of other customers and may be deemed as irregular usage.

The FUP (fair usage policy) is as below.

Travel sim (esim).

The high-speed data available per day is 3GB. Please be aware that if the daily usage reaches the amount above, the speed gets dropped to 200Kbps (maximum) without advance notice. The data connection speed is reset every midnight. Therefore, you can use a high-speed internet connection from the next day even after you experience a slow data connection by FUP.

Travel SIM (Physical SIM)

The high-speed data available is daily average of around 2GB. Please note well that if the daily average usage is above this amount for the past few days, the speed may drop to 200Kbps (maximum) without advance notice. Once it is restricted, you have to lower the daily usage to a few hundred MB for a few days for the speed to recover again.

The TRAVEL SIM (eSIM and Physical SIM card) is designed to be used by travelers and do not support long-term video streaming, video-conferencing/calling for extended periods of time, or downloading large amounts of data. If you plan on using for such purposes, please contact us , we would like to offer you our business plan (without FUP).

Please install the eSIM profile after you arrive in Japan. We sometimes see occasional errors when the eSIM is installed outside of Japan. Also, please note that the day you install our eSIM will be the day that rental period starts.

• If you purchase the eSIM before you arrive in Japan, then we will recommend you to install the eSIM on the day of arrival, as this will be the 1st day of the 10 days period.
• If you purchase the eSIM when you are in Japan, you can install it anytime depending on your needs, and that day will be the 1st day of the 10 days period.
• * e.g. Installing the eSIM at 00:00 on January 1 means you can use the eSIM until 23:59 on January 10.
• * e.g. Installing the eSIM at 23:59 on January 1 means you can use the eSIM until 23:59 on January 10.

Important information regarding the eSIM installation.

• You will need a stable internet/WiFi connection when installing the eSIM profile.
• The eSIM can only be installed once. Please DO NOT delete/remove your eSIM from your device after the successful installation.

No, you cannot make direct phone calls or send SMS text messages. Our travel eSIM plans provide data only. Telephone services such as Texts (SMS) and calls are not possible using a Data-only eSIM.

However, you can use internet connection-based calls and messages (i.g. WhatsApp, Messenger, Instagram, LINE, etc.) Or, if you are using an iPhone, you should be able to use iMessage and Facetime. If you would like to have a Japanese phone number, you may consider our Voice+Data SIM / eSIM, which will allow you to make / receive voice call as well as SMS.

A Tokyo Travel Guide

How To Get A Prepaid Voice/Data SIM In Japan for Visitors

Visitors to Japan can purchase and use prepaid voice and data SIM cards in Japan. Here are all the details you need to do so.

The Takeaway

• Note: b Mobile has stopped selling their PAY G SIM. So, for now, we recommend getting a regular data-only SIM without voice. For full details, visit our How To Buy A SIM Card In Tokyo page
• b-mobile offers a prepaid voice/data SIM for visitors to Japan.
• The SIM is called the PAYG SIM.
• You can order it online and have it delivered to your hotel in Japan OR
• You can purchase it at Yodobashi Camera shops in Japan.
• After purchase, you must submit scans of your passport photo page, proof of address and your entry stamp to Japan in order to use the SIM.
• The PAYG SIM offers 3GB of data, 60 minutes of calls and is valid for one week.
• You can also purchase a Japan SIM card online to pick up on arrival at Narita, Haneda or Osaka airports.

The Details

• Until recently, it was impossible for visitors to Japan to purchase prepaid voice SIM cards. The best way for visitors to get their own phone number was to rent a phone or use their own phone and risk exorbitant roaming charges.
• This situation changed in 2014 when b-mobile introduced the PAYG SIM prepaid voice/data SIM card. It’s a bit fiddly to purchase and use, but if you’re determined, see below for full details. If not, skip to the end of this page for links to my pages on prepaid data-only SIM cards, and pocket wifi or cellphone rental in Japan.

Check Hotel Availability

Destination, check-in date, check-out date.

Where to Purchase PAYG SIM cards

There are three ways/places to purchase these PAYG SIMs:

• Directly from the b-mobile site .
• At Yodobashi Camera stores in Japan.
• At the Hyatt Regency or Kyoto Royal Hotel and Spa in Kyoto.

After Purchase

• If you order the SIM online, it will be sent to a physical address in Japan that you specify (usually your first night’s hotel). If you purchase it from a store or hotel in Japan, you just carry it out of the shop. After receiving the card, you must do the following:
• Login to the b-mobile user site and enter the SIM details of the card and upload a scan of your passport photo page. If your passport photo page does not show your legal address (and most don’t), you’ll have to upload another form of identification that shows your legal address (a driver’s license etc) in addition to your passport photo page.
• On the activation date (that you specify when you purchase the SIM), b-mobile will send you an email saying the card is ready to use. Insert the card into your phone and set the APN settings.
• Login to the b-mobile user site and upload the same scan of your passport and proof of address, along with a scan of your entry stamp to Japan. This must be done within 24 hours of arrival. If you purchase the card inside Japan, you must do this within 24 hours of the activation date.

Other Options

Needless to say, this rather troublesome process will put off many potential purchasers. In fact, you REALLY have to want your own phone number in order to do this. For most people, it is MUCH easier to do one of the following:

• Buy a prepaid data-only SIM and make calls using Skype. For details, see my How to Buy a SIM Card in Tokyo page.
• Rent a phone and/or a pocket wifi (pocket router). For details, see my How to Buy a Prepaid iPhone SIM Card in Japan page.

Japan SIM Cards: Everything You Need To Know

by Melissa Giroux | Last updated Apr 25, 2024 | Asia , Japan , SIM Cards , Travel Tips

Visiting Japan soon? Make sure to know what to expect when it comes to purchasing a Japan SIM card .

In this guide, we’ll explain where to buy a SIM card in Japan in person and online. We’ll also discuss prepaid SIM cards and eSIMs if your mobile supports them.

Before you read this guide, you may wonder if you actually need a SIM card in Japan. If you don’t mind not having Internet, you’ll likely find free Wifi in restaurants, shopping malls, and hotels.

That said, if you need data to get around, call a cab, or translate Japanese – you may want to get a SIM card for your travels in Japan.

Best SIM Cards In Japan

If you’re traveling in Japan, we recommend using a SIM card from Mobal, SoftBank, B-mobile, or Airalo. (I’ll get back to Airalo later on, so keep reading to learn more!)

That said, if you’re planning on visiting other countries during your trip to Asia, you might want to make sure to pick an option that offers coverage in other Asian countries.

How To Buy A SIM Card In Japan

You can either buy a Japanese prepaid SIM card in person in some international airports, mobile provider stores, convenience stores, or online.

Usually, you can expect higher costs and low data offers at the airport, so we don’t recommend buying a SIM card at the airport.

That said, you won’t necessarily find SIM card shops in every airport, so it’s essential to keep this in mind. And, when you see a shop, you might also have limited options.

For this reason, I’d recommend buying a SIM card directly from the mobile provider store. Note that you may need your passport to buy one.

Although, this means you won’t get data right upon your arrival. So, if you prefer to be connected at all times, you could use an eSIM or purchase an Asia prepaid SIM card online.

Now, let’s take a look at the data plans offered by Mobal, SoftBank, and B-mobile.

Planning your upcoming adventures? Travel by bus! (It's cheap!)

Mobal sim cards.

Mobal offers several different tourist plans:

• Unlimited data, valid for 8 days for JPY 3,990 ($26.62)
• Unlimited data, valid for 16 days for JPY 5,990 ($39.96)
• Unlimited data, valid for 31 days for JPY 7,490 ($49.07)
• Unlimited data, valid for 30 days for JPY 7,500 ($50.04)
• Unlimited data, valid for 60 days for JPY 12,000 ($80.06)
• Unlimited data, valid for 90 days for JPY 16,500 ($110.08)

SoftBank SIM Cards

Softbank offers a prepaid SIM for travelers, which includes:

• 3 GB data, valid for 31 days for JPY 1,650 ($11.01)

B-mobile SIM Cards

B-mobile offers two SIM-only plans for tourists:

• 5 GB, 10 days, JPY 1,980
• 7 GB, 21 days, JPY 2,970

Overall, we think Mobal is the best option if you plan to buy your SIM card in person. That said, any would do if you can’t find their store!

How To Buy A Japan Prepaid SIM Card Online

If you wish to have your SIM card ready for your arrival, you could purchase it online or on websites like Amazon.

You’ll find different plans on Amazon. For example, the Prepaid Asia-Pacific SIM Card works in more than 17 countries and gives you unlimited data for 14 days. Japan is included.

But there are many other options worth considering, so have a look and make sure the countries you plan on visiting are listed.

Browse your options on Amazon

Another option is to purchase a prepaid Asian SIM card on SimOptions .

They currently offer two data plans in Japan:

• 10 GB, valid for 30 days for $24.90
• 10 GB, valid for 14 days for $49.90

Browse your options on SimOptions

Alternatively, you can order a Japan SIM card that you can collect at the airport or directly at your hotel on jrailpass.com .

This is the website where you can purchase train passes for your travels in Japan. So, while you’re there, you can purchase a SIM card and a train pass.

Here’s an overview of the plans available:

• 10 GB, valid for 15 days for $45.12
• 10 GB, valid for 30 days for $51.75

Browse your options on Jrailpass.com

Finally, the last option is to buy an eSIM card for Japan or, if you’re traveling to multiple countries, an eSIM plan for Asia.

How To Buy An eSIM Card For Japan

eSIM is a new concept that allows you to have a virtual SIM card inside your phone. If your mobile phone supports eSIM cards – it’s definitely one of the best options to get data in Japan.

Curious? Learn more about eSIMs for travelers on eSIM Roamers .

I started using eSIM as soon as my mobile phone supported it. And I first tried it when visiting my family in Canada. To buy eSIMs, I usually use Airalo . Keep reading to learn more about the best eSIMs for Japan.

Airalo Japan

If you want to buy an eSIM for Japan, you could purchase one on Airalo .

This website offers many eSIM cards worldwide and special plans for Asia and Japan. I’ve been using Airalo for several months, and it works fine.

Here are the options available :

• 1 GB, valid for 7 days for $4.50
• 2 GB, valid for 15 days for $6.50
• 3 GB, valid for 30 days for $8.50
• 5 GB, valid for 30 days for $11.50
• 10 GB, valid for 30 days for $18
• 20 GB, valid for 30 days for $26

Here’s an overview of the options available for Asia :

• 1 GB, valid for 7 days for $5
• 3 GB, valid for 30 days for $13
• 5 GB, valid for 30 days for $20
• 10 GB, valid for 30 days for $37
• 50 GB, valid for 90 days for $100
• 100 GB, valid for 180 days for $185

The options mentioned above are part of Asialink and offer coverage in 14 countries, including Japan.

Alternatively, if you’re traveling in other countries that are not mentioned on the list, you can try Discover Global, which offers coverage in 124 countries, including Japan.

Here’s an overview of the options available on Discover Global :

• 1 GB, valid for 7 days for $9
• 2 GB, valid for 15 days for $17
• 3 GB, valid for 30 days for $24
• 5 GB, valid for 60 days for $35
• 10 GB, valid for 180 days for $59
• 20 GB, valid for 365 days for $69

Now, one important thing to note about Airalo is that you’ll need to keep an eye out for the provider in each country.

Suppose you ever have trouble connecting to the Internet during your trip. In that case, it might be because you’re connecting automatically to networks and need to select a network manually instead.

When you purchase the eSIM, you’ll get access to the list of networks supported in each country.

Go to Airalo

Japan Wireless offers two types of data plans in Japan. You can choose between a 30-day plan and a daily plan.

Final Thoughts On SIM Cards In Japan

As you can see, getting a prepaid SIM card in Japan or even an eSIM for your travels in Japan is pretty straightforward.

You’ll even be able to stay connected wherever you go in Asia without changing your SIM card, especially if you purchase an Asia plan.

I believe the eSIM card is the most convenient way to get data in Japan if you wish to have data upon your arrival. This way, you won’t need to go to a store to buy a SIM card.

Obviously, you need to make sure your mobile phone supports eSIM first.

Japanese Visitor SIM Cards: Which is the Best SIM Card for Japan?

Heading to the land of the rising sun? You might think that travelling to such a technologically advanced country would mean you have no problems getting connected. But Japan can present some difficulties for short term visitors, keep reading to find the best SIM card for Japan.

By law, visitors on a tourist visa are not allowed to buy voice SIM cards, so your only option is to buy a prepaid data only SIM, and then use VOIP apps if you need to make calls. On this page I look at the options for buying different tourist data only sims and then look at another option of renting a voice SIM.

 Where to Buy?

Some airports have vending machines, and some have 7-11 stores where you can purchase SIMs. You can also head to an electronic store. Yodobashi Camera and BIC Camera stores will stock these SIM cards and can be found in the centre of all major towns and cities. These SIMs are not triple cut and the Nano, Micro and full size SIMs come in different packaging; so make sure you pick the right one.

Alternatively, you can order a SIM online, and have it delivered either internationally to your home, or to your hotel to pick-up on arrival.

Japan has three major phone networks, and has no GSM network but widespread 3G and 4G/LTE. So if your device is not 3G/4G, then it will not work.

Phone / Wireless Hotspot Mifi rental

If you really need to make phone calls, and can’t use VOIP services like Skype; then renting a phone is another option.To get around the SIM laws, companies offer rental of phones and wifi hotspots. These can be sent to your hotel, or picked up from electronics stores and at the airport. Try:  https://www.rentafonejapan.com/

If your phone is locked and you cannot fit a data SIM card, you can also rent a wifi hotspot from this company. Alternatively you could place your data SIM in your own mifi. 

 Wifi Availability

There is a growing number of free Wifi hotspots, in shops, stations, hotels and trains etc.

Can’t be bothered with buying a local SIM in Japan? Want to buy before you fly?

[amazon box=”B0722XVZT4″]

‘Our top pick’

Just like the BMobile SIM, the iijmio travel SIM is easy to purchase, and quick to setup, with comprehensive instructions in many different languages, but this one comes with options for longer stays. English customer support is also available.

It also includes the Brastel Card, which acts as a prepaid calling card; allowing you to make calls through an app. By topping up the app you can then make calls through it to regular land and mobile phone lines. Just like Skype or other (VOIP service).

Two options:

• 1 GB for 30 days
• 2 GB for 90 days

It also Includes access to free wifi hotspots across Japan, and comes with nifty souvenirs – origami paper and decorative screen.

Speed: Up to 375 Mbps download speed/50 Mbps upload speed

Where to buy? You can buy online, through Amazon, or locally. Find a list of shops here .

   Customer Service

• Call:   03-5205-4999  between hours 9am – 7pm (Japan time)

Can’t be bothered with buying a local SIM in Italy? Want to buy before you fly?

OneSIM offer an international SIM card that lets you save up to 85% in roaming fees in 200+ countries.

It can be sent out ahead of time so you hit the ground running.  Find out more here.

B Mobile, one of the largest and oldest providers, have a good reputation and extensive coverage across the country.

Guide to Japanese SIM Cards for Travelers

Should you choose a SIM Card to travel in Japan?

Purchasing a prepaid SIM Card is one of many options for you to connect to the internet when traveling abroad.

Connection to the internet has become nowadays a MUST when traveling to a foreign country, and Japan is not the exception.

The question is: How useful is purchasing a SIM Card when traveling to Japan?

In this article, I will show you this guide to Japanese SIM Cards for travelers: from the variety of SIM Card services to connection speed, and even how to purchase a SIM Card.

I hope this information is useful for you when traveling to Japan.

*Please note that this article contains affiliate links.

Why choose a SIM Card

Since there are many options for you to choose from when it comes to internet connection, it is important to know the “Pros” and “Cons” of using a prepaid SIM Card.

What are the merits of buying a prepaid SIM Card (Pros)

• Relatively cheap
• Easy to use once you are connected
• After your visit, you just dispose of the SIM Card and that’s it.

What are the possible downsides of buying a prepaid SIM Card (Cons)

• Can only be used for one device
• It is not compatible with every mobile phone
• Services usually don’t do refunds if you’re mobile phone happens to not be compatible

5 Best SIM Card services in Japan

Here are 5 of the most popular SIM Card services that you will be able to find for your Japan trip.

Mobal is a MVNO(Mobile Virtual Network Operator) that offers unlimited data cards for 8 days, 16 days, and 31 days. They offer free shipping to most countries in the world as well as various pickup locations within Japan.

The biggest appealing point about mobal’s SIM Cards is that they offer both “data-only SIM” and “data+voice+sms SIM”. The latter one is more expensive, of course, but if being able to use the phone is a priority for you, this is your pick.

Official Website:  https://www.mobal.com/japan-sim-card/

2. Japan Wireless

Japan Wireless offers fixed data limit cards but at a relatively cheaper price. The prepaid SIM Card that they offer is for either 7 days, 15 days, or 30 days with a data amount of 500 MB/day.

Although they don’t offer international shipping, they can send the SIM Card to the airport of your arrival, the hotel where you’re staying, or the nearest post office from you. They also provide support via phone and email, both in English.

Official Website:  https://www.japan-wireless.com/en/rates

3. Simcard Geek

Simcard Geek offers both unlimited data cards and cards with a fixed data limit. Fixed data limit cards are slightly cheaper than unlimited data cards, so if you’re planning on not using the internet a lot, then this might be a good choice for you.

Simcard Geek also provides free worldwide shipping, but depending on the shipping location, it may take between 5 to 12 days in reaching you. So you will need to make the order quite in advance.

Official Website:  https://www.simcardgeek.com/product-category/japan-sim-cards-for-tourists/

4. Japan Travel SIM (IIJmio)

Japan Travel SIM does not have an official website where you can pre-order. But instead, you will find this SIM Card in most electronic shops across Japan. So if you rather go to a shop after getting to Japan to purchase your SIM Card, then this is your choice.

You can also find this SIM Card at Amazon.com, so it is also possible to get it before your trip to Japan.

They offer fixed data limit cards (1GB/30 days, 2GB/90 days) but are rechargeable within the validity period.

Official Website:  https://t.iijmio.jp/en/index.html

5. U-mobile SIM

U-mobile SIM provides data-only SIM cards with a fixed data limit. The prepaid SIM Card that they offer is for either 7 days or 15 days, with a data amount of 220MB/day. This 220MB is high-speed data and if you pass this data amount, your connection speed will fall to 200kbps.

U-mobile SIM is available at the shop counters in the major airports in Japan. You can also find them at Narita airport’s SIM vending machines. Although they don’t provide support and data amount is limited, it is by far the cheapest option.

Official Website:  http://umobile.jp/lp/prepaid_eng/

How to Buy SIM Cards in Japan

There are several ways you can purchase a prepaid SIM Card.

• At the airport: There are shop counters at the major airports in Japan. But be aware that these counters are not opened 24 hours. You can also find SIM Card vending machines at Narita Airport, although they are charged with a surcharge.
• At electronic shops:  SIM Cards can be purchased pretty much at any electronic shop in Japan. If you’re in Tokyo, you shouldn’t have any problem finding a shop where they have prepaid SIM Cards. The largest electronic shops are “Bic Camera”, “Yodobashi Camera”, and “Yamada Denki”.
• Online: Many MVNOs have their own website where you can preorder your SIM Card before coming to Japan. Some services have international free shipping, some have specific points of pick-up such as airports, and others will send it to the hotel where you’re staying. Other than MVNOs, you can also find online travel agencies that offer this service such as Klook. Amazon.com also has SIM Cards that you can buy before your trip.

Some WiFi rental services will also have the option to provide a prepaid SIM Card if that’s the option you want to go with. At Japan Wireless, you can purchase a SIM Card from their website.

Which is Better in Japan, SIM Card or Pocket WiFi

Another thing I would like to suggest is to rent a pocket WiFi. You can rent a Pocket WiFi online just the same as you would a SIM Card, and pick it up at the airport of your arrival or the hotel you’re staying at.

Here is a chart comparing SIM Card purchasing vs Pocket WiFi rental.

• Speed: Both, SIM Card and Pocket WiFi have a high-speed internet connection, even though when it comes to the SIM Card there is usually a daily limit of high-speed connection.
• Coverage: Again, both options have a wide coverage when it comes to internet connection.
• Cost: Although the pocket WiFi rental isn’t that expensive to begin with, it is usually cheaper to buy a SIM Card.
• Practicality: The SIM Card is more practical in the sense that you don’t need to carry around an extra device and worry about the remaining battery amount. Also, in the case of the pocket WiFi rental, it is necessary to return the device (even though not complicated), which is something you don’t need to worry about in the case of a SIM Card.
• Multi-device: The biggest weakness of the SIM Card is the fact that you can use the internet connection only for one device. On the other hand, the pocket WiFi is able to connect multiple devices at once.
• Heavy using: Prepaid SIM Cards tend to have a daily limit amount of high-speed data, and afterwords the connection slows down. Some pocket WiFi also have this problem, but there are also some pocket WiFi rental services that provide unlimited high-speed internet connection.
• Compatibility: If you’ve never used a SIM Card before, then this might be your biggest concern. First, you need to make sure that the mobile phone you’re taking to Japan is unlocked. After that, you need to make sure the SIM Card you’re purchasing is compatible with your mobile phone. This is a concern you won’t have in the case of a pocket WiFi device.

FAQ about SIM Cards in Japan

Q1. How can I install and activate the prepaid SIM card?

This actually depends on the service you’re using. Most SIM Cards are as simple as inserting it into your mobile phone and following the instructions. Sometimes a brief registration process is required in order to proceed, but most times you don’t have to do that.

Q2. How can I know if my mobile phone is compatible with a SIM card?

First, you have to make sure that your mobile phone is unlocked or is a SIMfree mobile phone. If your mobile phone is locked, that means you can’t use the network of carriers other than yours.

Another thing that you need to know is the size of your SIM card. Most SIM card services provide all sizes, but sometimes that is not the case. So be sure to ask before purchasing.

If your mobile phone is relatively new, you have a good chance that you won’t have compatibility problems. But just to make sure, you can search the compatibility of your mobile phone by visiting the “willmyphonework” website.

Willmyphonework Website: https://willmyphonework.net/

Another thing you can do is just ask your mobile phone provider if it’ll be compatible.

Q3. What other alternatives are there to connect to the internet in Japan?

Other than purchasing a prepaid SIM Card and renting a pocket WiFi, there are many other ways you can get access to the internet.

First, there is the Free WiFi That many companies provide. You can find it in airports, train stations, hotels, and some cafes. There are also services where you can rent an entire phone with data included. There is also the option of international roaming which you would have to discuss with your phone provider.

An unconventional way would also be to go to an Internet Cafe. But that would be inconvenient unless you are interested in the experience itself.

As you can see from the previous comparison chart, both the SIM Card and the pocket WiFi have their own strengths and weaknesses.

Prepaid SIM Cards are practical in the sense that you don’t need to carry an extra device, you don’t need to return anything at the end of your journey, and the setting is fairly easy as long as it is compatible.

On the other hand, the pocket WiFi is good for multiple device connectivity and heavy internet usage. You also don’t need to worry about device compatibility.

Personally, I would recommend renting a pocket WiFi. If you’re traveling in a group, it would be cheaper to rent a pocket WiFi as opposed to buying several SIM Cards. Even if you’re traveling alone, it is most possible you’ll have more than one device you’d like to connect to the internet. Plus, the pocket WiFi device is not bulky so it won’t be much of a bother, and returning the device is as easy as putting the set in any postbox in the country.

Now that I have recommended you to rent a pocket WiFi, the next question would be: where can you get a pocket WiFi device?

Usually, you can order one online and the device will be sent to either the airport of your arrival or the hotel you’re staying at for you to pick up.

There are many companies that offer pocket WiFi rental services. Here is an article where I compared some of the most popular pocket WiFi rental companies. I also provide discount coupons at the moment, so don’t miss this chance.

Should I get a SIM Card when travelling to Japan? SIMカード

• Published on : 12/04/2023

Prepaid SIM cards allow for high-speed data usage during travels to Japan, but whether or not purchasing one is the best option for an upcoming trip depends on the individual. We'll compare a temporary Japanese SIM card to other popular options for staying connected. 

What is a Short-Term Japanese SIM Card? 

A Subscriber Identity Module (SIM) card is a standard part of any cellular mobile device and allows said device to connect to a network for usage. Oftentimes, visitors to Japan will look into purchasing a temporary SIM card for using international phone data prior to their trip. 

For using these SIM cards in Japan, one can choose the period of valid usage ( 8 days, 16 days, or 31 days ) and then have it sent to their delivery address in their home country prior to departing for their trip. After arriving in Japan, the SIM card can be inserted into their phone or device then configured using the directions found here . Simultaneously, SIM cards can be sent to a traveler's place of stay within Japan after they've arrived.

Be aware that only an unlocked phone  can use the Japanese SIM card, so be sure to check for phone compatibility prior to purchasing. Also note that the SIM card does not support access to phone calls or SNS messaging, but making calls through messenger applications like LINE (the most popular service in Japan), Whatsapp, or another service is possible and largely standard.

In order to assess if a SIM card is the best choice as an international traveler, we’ll compare using a SIM card to three of the most common alternatives; Data roaming with pre-existing phone plans, foregoing individual data and instead relying on free public WiFi , and renting a pocket WiFi device.

SIM card installation

SIM Card vs Data Roaming 

Data roaming is utilizing mobile data provided by a local cellular provider that has a contracted agreement with a provider back in a traveler’s home country.

Roaming varies by provider, individual plans, and the country of travel, so how the conditions of data roaming compare to that of a SIM card varies largely by individual tourists and their phone usage.  

However, in general, roaming entails additional fees added to the base contract costs. For travelers where this is the case, the SIM card may be an enticing option, as it is a prepaid expense with no extra hidden charges.

Data roaming notification

It’s important to note that oftentimes roaming charges are issued on a daily basis with limits set in place, meaning that expenses can stack up quite easily and unexpectedly. On average, U.S. cellular providers will charge anywhere from 10 to 30 USD per day for roaming data in Asia. Other companies may also price roaming on a per-megabyte basis. Through a Japanese SIM card, the unlimited data included in the base price allows for visitors to be connected at all times. 

For those with adequate roaming options already included in their phone plans there will be no issue. However a prepaid SIM card removes a lot of the guesswork that may come for those who do not have innate roaming included in their phone contracts. 

SIM Card vs Public WiFi

For some, foregoing personal data and fully relying on free public WiFi is an option. This is often done as it entails no additional expenses or contractual obligations, but with that, there are a number of drawbacks. 

First off, visitors are often under the heel of WiFi internet accessibility. Though Japan is often celebrated for its technological advancements (and often lives up to such praise), WiFi access is actually somewhat rare compared to other countries like Korea or Taiwan. Public WiFi access is often found in some cafes (predominantly large chain institutions such as Starbucks or Doutor), or places of accommodation . Many train stations offer public WiFi, however, accessing them often require a sign-up or log-in and aren’t always consistent or dependable, though the option is always there for those who need it. 

Additionally, security is a potential issue that may arise when operating solely on free public WiFi.

If someone is handling sensitive or personal information, they should be aware of the risks that may come up. Through a SIM card, data is used individually and kept private, avoiding these security risks. 

So given all these caveats, does foregoing personal data usage for free public WiFi work well for any visitors? For individuals traveling to Japan for business trip purposes and will predominantly be spending their stay at hotels , offices, or meeting spots, depending solely on the internet options provided at these locations may be more than adequate. Though, if one falls under this category, be aware that the security risks still exist. Working with confidential information should be avoided or done with a reliable Virtual Private Network (VPN) service.

SIM Card vs Pocket WiFi

Pocket WiFi devices are one of the primary means of mobile data usage for travelers to Japan. In fact, pocket WiFi devices are often compared and contrasted to individual SIM cards during pre-departure preparations and research due to their similar functions, similar price, and popularity.

Through Japan Experience, pocket WiFi devices are available for rental at a price starting at 44 USD for 5 days and SIM cards are available for purchase at a price starting at 29 USD for 8 days . 

If one has reserved a pocket WiFi device, they will need to pick it up at the airport upon arrival or have it sent to their place of stay within Japan. From here, it is simple to use and just requires a password to connect to the WiFi hotspot. 

A pocket WiFi carries some stand-out benefits, most notably the ability to host multiple connections at once through a hotspot. This is especially beneficial to those traveling within groups or families who wish to share internet access along with those needing to operate multiple devices, like tablets or laptops, during their trip. 

There are some things to keep in mind, however, that may make an individual SIM card the better option for some visitors. As previously mentioned, the pocket WiFi is a separate device that must also be carried around to use. In addition, it has its own power source. While the pocket WiFi has a long and dependable battery life, it will need to be charged and if it runs out of battery, the network will not be accessible. There is also a range limit of 20 meters for hotspot access, and while this is quite far and adequate for most situations, it is something to keep in mind. Individual SIM cards are inserted into mobile devices and thus have no physical accessibility limitations and can be used the entire time without the need of a hotspot connection. 

Ultimately, both options boast a range of benefits for mobile data in Japan and which is best depends largely on the conditions individual travelers will face during their stay. 

Is a Short-Term Japanese SIM Card right for me?

A short-term Japanese SIM Card is a great option for using mobile data in Japan in a cost-effective manner, but its utility in comparison to other options largely depends on a traveler’s specific conditions and needs. Essentially, the continued use of one’s personal device with high speed internet helps to streamline the travel process more, so adequate research for the best options is an essential part of pre-departure preparations. Either a temporary Japanese SIM card or a rentable pocket WiFi device will satisfy the needs of a majority of travelers and ensure that one is connected the entire time of their stay in Japan.

The best SIM cards for travelling to Japan

Make your next Japan trip – whether it’s for business or relaxation – pure pleasure with our guide to the best SIM cards for travelling in Japan.

• Roaming in Japan
• Best Japan Travel eSIM

Best Japan Travel SIM

• Best Japan Roaming SIM

Best SIM option within Japan

Roaming in japan, or 日本で国際ローミング.

Japan has been an important trading partner for Australia for many decades, so many businesspeople will find a need to head to Tokyo on a regular basis. Moreover, it’s also one of the most often-cited desired travel destinations for Australian holidaymakers, whether you’re getting seriously into Japanese cuisine in Osaka or hitting the snow slopes in Hokkaido.

While you don’t have to shift too many time zones – or for Western Australia, any time zones at all – to travel to Japan, one factor you should take into account is how you’re going to manage your mobile connectivity while you’re there. There’s no absolute “best fit” solution that works for everyone, so this article will run through your best choices across standard travel SIMs , travel eSIMs, roaming and local telco choices:

• Bali Travel SIMs
• New Zealand Travel SIMs
• Europe Travel SIMs
• USA Travel SIMs
• UK Travel SIMs
• Airalo Roaming eSIM review

Best Japan eSIM you can purchase globally

Disclaimer: This pack only offers data roaming. No calls or SMS are included in the plan price.

Most Australians are familiar with the telco Circles.Life. The Optus 4G Plus-powered SIM provider has taken Australia by storm with some ridiculous deals on mobile data. Well, Jetpac is the company's foray into the global Travel eSIM market, a singular solution for frequent flyers that's available in over 100 different countries. So long as you've got an eSIM-compatible phone , you can purchase and activate a Jetpac eSIM from anywhere in the world. 

Jetpac's Japan eSIM is actually no different from its Asia Pacific eSIM. So not only can it be used nationwide in Japan, but also in 14 other popular Asia Pacific countries, including but not limited to Australia (G'day,) China, Hong Kong, India, New Zealand, the Phillippines and Thailand. 

Plans start from $1.50 for 1GB with a 4-day expiry but 30-day can cost anywhere between $13.50 for 5GB or $94 for 40GB. Follow the link below for a full list of Jetpac payment plans.  

As the name suggests, eSIM Japan provides eSIMs as its business model with a range of very competitively priced plans that work primary for short trip travellers, with most plans sold with between 3 to 12 days of validity. You can choose between “unlimited” plans – really they’re just data packs with 384kbps speed capped data once your daily quota is exhausted – or data quota deals with a fixed amount over 7, 15 or 20 days.

One oddity with eSIM Japan is that it also offers the same plans as “city” plans for many popular destinations such as Tokyo, Kyoto, Hiroshima, Osaka and Sapporo. They appear to just be the same plans as the nationwide ones, however, so it’s arguably best to stick with those.

eSIM Japan uses the KDDI network in Japan.

Mobal Short Term SIM

There’s a number of choices in the Japan Travel SIM market that you can order before you leave Australia from brands such as Sakura Mobile and B-Mobile, but if you are going the Travel SIM route it’s hard to overlook Mobal’s short-term tourist SIMs. Starting at ¥4,730 (~$50 AUD, depending on exchange rates) for an unlimited data-only 8 day SIM up to ¥7,920 (~$83) for a full 30 days with unlimited data.

It's worth noting that Japan allows a, shall we say, more “loose” definition of “ unlimited ” than you might think would apply, before you plan to start downloading the entire Netflix back catalogue to your tablet. Most plans are limited to 3GB of data per day, after which data speeds “may” be reduced. For most tourists being prudent 3GB a day is plenty enough, even if you are uploading most of your food and location snaps to Instagram at a frenzied pace.

Mobal’s SIMs work on the Softbank and Docomo networks in Japan with a claimed 99% population coverage, which should cover most places you’re likely to go on business or holiday within Japan.

Best Australian deal for Japan roaming

Vodafone $5 roaming.

Vodafone remains the gold standard for global roaming if what you’re after is simplicity. Simply sign up for a qualifying Vodafone postpaid plan, and you can access the inclusions on your plan while travelling throughout Japan for just $5 per day. If you don’t use your phone on a given day, there’s no charge at all, though you also don’t get any of your speed capped data if you’ve already exhausted your monthly quota. In those cases you’ll pay an additional $5 to top up 1GB of data.

Here's a selection of Vodafone plans that support $5/day international roaming

However, as with rival Optus’ $5/day deal or Telstra’s variable price “Day Pass” options, this kind of roaming within Japan can quickly add up if you’re there for a longer holiday or business trip. $5 once doesn’t feel like much, but bear in mind that over a fortnight that’s a spend of some $70 extra on top of your existing bill.

Vodafone isn’t the only telco offering roaming within Japan from your standard Australian SIM, either. Here’s a range of providers who support call, text and data roaming in Japan

BIC Camera SIM

When you land in any Japanese International Airport, you’ll see a number of providers offering local SIM cards and Wi-Fi hotspot devices to tourists. They’re not a terrible deal if you want absolute convenience, but you can typically do a little better by opting for a truly local SIM card.

Only one problem here: As with many countries not all plans are sold to visitors, and your grasp of the Japanese language might be sketchy to non-existent.

Your best and most affordable bet in this case is to head to a BIC Camera store. The vast majority of Australian vistors will be landing in Tokyo, and there’s no shortage of BIC Camera stores throughout Tokyo, but also in basically every other major city as well.

Why BIC Camera? Partly the ubiquity of its stores (also fun to browse for everything from electronics to bicycles, luggage to anime figures and plenty more besides), but also because most BIC Camera stores are quite large and you’re more likely to find a staff member or two with enough English language savvy to meet your needs for a SIM when you’re there. BIC also sell other SIM cards so it’s worth checking if there’s a good seasonal deal while you’re there.

If your current handset doesn’t support eSIM, then sadly, the answer is no. There’s no magic bolt-on or software app that can add the needed virtual SIM circuitry to a phone that doesn’t support eSIM out of the box.

If your phone does support eSIMs, then it’s quite simple to set up your eSIM before you travel. We’ve got a handy guide to setting up eSIMs for Apple iPhone and Android here .

It wasn’t that long ago that the answer to that question would have been no, with public WiFi very thin on the ground even within hotel accommodation.

The Tokyo Olympics didn’t go to plan, but one factor that was planned in was a wider pitch to tourists, and this included a huge expansion of available free WiFi options. Having travelled extensively through Japan over many years, I can say that it’s better than it used to be – but it’s hardly simple, and can be a tad baffling if you don’t have a decent grasp of written Japanese for signing into web portals and such.

You could get by with a little patience and pre-planning if your accommodation offers WiFi, though. There it’s more likely to support simple sign-ins, and if you offload maps, podcasts and video content from there to keep you going, and then use the WiFi in coffee shops and some shopping centres, you might be able to do so for no additional cost.
