SIM Cards in Japan: The Best Prepaid Plans | 2024 Guide

Japan – known for anime, cherry blossom trees & the crazy number of (reasonably priced) vending machines.

The country is also known for sumo wrestling, the Shinkansen train & technological advancements.

Whenever I watch some anime or manga, which is rare, I always feel like going to Japan, get some groceries & certainly buy leek for the authentic anime grocery shopping experience.

But you are probably not going to Japan just to get some leek (at least, I hope not).

If you can, you certainly want to go to Mount Fuji (do not call it Mount Fiji 🤪).

And the many stunning castles or temples across the country, such as Kinkaku-Ji, Kiyomizu-Dera & Osaka Castle.

And anime and manga lovers want to go to Akihabara – even those who are not into those things, like myself, will still be in awe by all the stores nearby.

As you can see, there is no reason to be bored in Japan – and I only mentioned a handful of things to do!

What you should not do, in many cases, is roam internationally in Japan – International roaming can be expensive.

That is why I always recommend local prepaid SIM cards, eSIMs & even travel eSIMs so that you can enjoy low rates for data, minutes & SMS.

Most Japanese mobile operators do not offer prepaid SIM cards to tourists because of a low prohibiting travelers from getting voice-enabled SIM cards.

Yes… if you get a SIM card in Japan, it will always be data-only… with one exception.

So, how much do SIM cards cost in Japan?

You can get a Japanese (tourist) SIM card for 4500 JPY (29.90 USD) from SoftBank in their stores. MVNOs sell SIM cards for between 1780 JPY (11.85 USD) to 26 400 JPY (175.45 USD). SIM cards are also sold at various airports, including (Tokyo) Haneda Airport (HND).

With almost all of the options mentioned above, you can pre-order your SIM card so that they are waiting for you at the airport or a post office close to your accommodation (or it can be delivered there too for a slightly higher fee).

Unlike some other countries in East– and Southeast Asia, (prepaid) SIM cards are not as accessible as in other countries, but it is still doable.

In this guide, I will go over everything you need to know about buying a SIM card in Japan. Let's go.

Buying a SIM Card in Japan Guide (logos of SoftBank, Mobal, COMST, B-Mobile, Wireless Gate, Wi-Ho!, Nippon SIM for Japan, GTN Mobile, Sakura Mobile & IIJmoi Japan Travel SIM)

What is the Best SIM Card in Japan?

If you want to buy the best SIM card in Japan, I recommend going with COMST, Mobal, Nippon SIM & Sakura Mobile. All use the NTT DoCoMo network, which is the best in the country. Nippon SIM and Sakura Mobile have unlimited plans. COMST is the only one with 5G NR access.

Phone Travel Wiz Approved Seal

Japan has one mobile operator and nine Mobile Virtual Network Operators (MVNOs) offering prepaid services easily accessible to travelers:

  • SoftBank Japan
  • Bmobile Japan (NTT DoCoMo MVNO)
  • COMST Japan (NTT DoCoMo MVNO)
  • GTN Mobile Japan (NTT DoCoMo MVNO)
  • IIJmio Japan Travel SIM (NTT DoCoMo MVNO)
  • Mobal Japan (NTT DoCoMo MVNO (data-only) & SoftBank MVNO (with calls/SMS)
  • Nippon SIM for Japan (NTT DoCoMo MVNO & SoftBank MVNO (for one SIM card only))
  • Sakura Mobile (NTT DoCoMo MVNO)
  • Wireless Gate Japan (NTT DoCoMo MVNO)
  • Wi-Ho! Japan (NTT DoCoMo MVNO)

In this guide, I will only stick to the mobile operator and MVNOs bolded above, as they are the most popular options for travelers.

I decided to stop reviewing MVNOs (in most cases) and spend that testing time on travel eSIMs (like the ones for Japan, for example) instead because most Phone Travel Wiz readers avoid MVNOs. But if you really want a SIM card from an unbolded option, you have to do the research yourself, I am afraid.

Anyone 18 or older living in or visiting Japan can buy a Japanese SIM card with some restrictions, and you do have to comply with Japan's SIM card registration regulations.

And if you are younger than 18, you can still get a SIM card if your parents buy one for you (in their name).

The main restriction is that short-term visitors cannot buy voice-enabled Japanese SIM cards.

This means that SIM cards mentioned in this guide are data-only and targeted at tourists (except for Mobal).

Besides those restrictions, you are free to use Japanese (tourist) SIM cards.

Regarding the registration requirements, you must show your passport at the point of sale.

Where Can You Buy a Japanese SIM Card (+Prices)?

You can get a Japanese SIM card in (select) Softbank stores. Resellers, like convenience stores and electronic shops, also sell SIM cards. It is also possible to get SIM cards at select airports, including (Tokyo) Haneda Airport (HND) and (Tokyo) Narita International Airport (NRT), or get them delivered to post offices or your accommodation.

    You can expect to pay the following for Japanese SIM cards:

  • SoftBank Japan: 4500 JPY
  • COMST Japan: 2420 JPY – 8800 JPY
  • IIJmio Japan Travel SIM: 1990 JPY & 3020 JPY
  • Mobal Japan: 3990 JPY – 16 500 JPY
  • Nippon SIM (for Japan): 1780 JPY – 1980 JPY
  • Sakura Mobile: 4950 JPY – 26 400 JPY
  • Wireless Gate Japan: 2420 JPY – 8800 JPY

Be aware that SIM cards sold at airports can be more expensive than the prices mentioned above.

Use the Wise Currency Converter tool (free) for up-to-date JPY (Japanese Yen) to your currency (let's say HKD – Hong Kong Dollar) exchange rates.

  • 100 JPY = 0.65 USD
  • 1000 JPY = 6.65 USD
  • 10 000 JPY = 66.45 USD
  • 100 000 JPY = 664.55 USD

(Travel) eSIMs for Japan

The use of (travel) eSIMs has exploded in recent years.

Not only do more phones have eSIM capability (some US-sold iPhones are eSIM-only), but the number of providers adopting technology has proliferated as well.

This includes local mobile operators offering eSIM and platforms selling eSIMs (travel eSIMs).

If you want a local Japanese eSIM, you can get one from Bmobile and Nippon Japan.

But remember that you have to comply with Japan's SIM card registration regulations, even when you get a Japanese eSIM.

If you do not wish to deal with registration for whatever reason, like privacy, consider getting a travel eSIM for Japan.

Many eSIM providers have eSIMs for Japan only, eSIMs for multiple Asian destinations & even global eSIMs, which I discuss in my Japan eSIM buying guide.

Buying an eSIM for Japan Guide (logos of SimOptions, Nomad, Asialink, Discover+, Moshi Moshi, Holafly, Alosim & Airalo)

Here is a quick introduction to your Japan travel eSIM options:

  • Airalo: Japan (Japan only), Asialink (14 countries in Asia) & Discover+ (130 countries worldwide + up to 200 worldwide minutes & 200 worldwide SMS)
  • Alosim: Japan
  • Holafly: Japan & Asia – all variants include unlimited data
  • Nomad: Japan, APAC (15 or 20 countries, depending on the variant) & Global (109 or 139 countries, depending on the variant)
  • SimOptions: Asia (32 countries)

And I know you love discounts, so use one of these codes when getting a travel eSIM:

  • Airalo: NEWMAY15 for 15% off (if you have never bought an Airalo eSIM before). Otherwise, AIRALOMAY10 for 10% off (for existing users) – only the first 3000 users can redeem either discount code)
  • Alosim: PTW for 5% off (as many times as you wish for as many eSIMs as you want)
  • Holafly: PHONETRAVELWIZ for 5% off (as many times as you wish for as many eSIMs as you want)
  • Nomad: ADU123 for 3 USD off (on your first-ever Nomad order only)

If you want to know about all the prices, data options & covered countries (for the regional and global eSIMs), check out my Japan eSIM buying guide.

Japanese Prepaid SIM Cards Explored

Below, I will guide you through SoftBank Japan, COMST Japan, IIJmio (Japan Travel SIM), Mobal Japan, Nippon SIM for Japan, Sakura Mobile & Wireless Gate Japan, and go through:

  • Background information
  • Mobile coverage
  • SIM card types, prices, and availability
  • Recharge/top-up information
  • Combo plans, data plans, and special packs (such as social media packs)

Let's see what Japan can offer us in terms of SIM cards.


SoftBank Japan

SoftBank Japan Logo
© SoftBank Japan

SoftBank Japan, just SoftBank, is the third-largest mobile operator in Japan.

It is currently the only mobile operator offering prepaid services (or a travel SIM card) to travelers (NTT DoCoMo has prepaid options for residents only, while AU Japan and Rakuten Mobile discontinued their prepaid lines altogether).

SoftBank has the best 5G NR availability.

But you cannot use 5G NR with the SoftBank tourist SIM card.

SoftBank uses the following frequencies:

  • 2G: N/A – shut down in 2012 (yes, about a decade ago)
  • 3G: 900 MHz & 2100 MHz
  • 4G/LTE: 700 MHz (Band 28), 800 MHz (Band 18 – not the usual Band 20), 900 MHz (Band 8), 1500 MHz (Band 11), 1800 MHz (Band 3), 2100 MHz (Band 1), 2500 MHz (Band 41) & 3500 MHz (Band 42)
  • 5G NR: 3700 MHz (n77) – not for prepaid customers… yet
  • VoLTE: Yes, but you cannot make calls as a tourists
  • VoWiFi: Yes, but you cannot make calls as a tourists

This is what you will learn about SoftBank:

* Coverage
* How to Get a SoftBank SIM Card & SIM Card Price
* Topping Up Options & Methods + Balance Check
* Plans & Packages
* APN/Internet Settings

Coverage – SoftBank Japan

SoftBank has excellent coverage throughout Japan.

While this is true for all the other Japanese mobile operators, it is still remarkable.

Below is SoftBank's coverage map produced by Speedtest:

SIM Card Price – SoftBank Japan

You can get a SoftBank tourist SIM card for 4500 JPY in SoftBank stores. Resellers, including electronic stores, sell them too. SoftBank tourist SIM cards are also sold at airports, including (Tokyo) Haneda Airport (HND) and (Tokyo) Narita International Airport (NRT).

While SoftBank has regular prepaid SIM cards, which is uncommon for Japanese mobile operators nowadays, you need to have a Japanese Residence Certificate (Jūminhyō – 住民票) to get one, which is why they are not mentioned in this section.

  • Find out how much SIM cards cost in every country, including data-only SIM cards and tourist SIM cards, offered by each mobile operator + information about starter benefits (lookup tool)
SIM Card Prices Worldwide Tool by Phone Travel Wiz

While SoftBank does have eSIMs, they are (currently) not offered to those with tourist SIM cards.

You may want to get a travel eSIM for Japan, which can be cheaper than getting a SIM card from SoftBank (in some cases).

Especially when getting an eSIM covering popular Asian destinations if you do not stay in just Japan or a global eSIM valid for up to a year if you want one eSIM to work practically worldwide.

My Japan eSIM buying guide analyzes various eSIM options of eSIM providers I have tested extensively worldwide.

Here is a quick introduction to them:

  • Airalo: Moshi Moshi (Japan only), Asialink (14 countries in Asia) & Discover+ (130 countries worldwide + call and text feature) – use code NEWMAY15 (15% off – first-time users only) or AIRALOMAY10 (10% off)
  • Alosim: Japan – use code PTW (5% off – no limits)
  • Holafly: Japan & Asia (11 countries) – these eSIMs have unlimited data – use code PHONETRAVELWIZ (5% off – no limits)
  • Nomad: Japan, APAC (up to 20 countries) & Global (up to 139 countries) – use code ADU123 (3 USD off – first-time users only)

For more information, such as the prices and data allowances, check out my Japan eSIM buying guide.

But let's continue with SoftBank for now.

Note that SoftBank offers VoLTE (Voice over LTE (4G)) and VoWiFi (Voice over WiFi).

But as you can only get data-only SIM cards in Japan, the features will not be available to you 😓.

Coverage – COMST Japan

COMST is an NTT DoCoMo MVNO, meaning COMST uses the NTT DoCoMo MVNO network and does not have its own mobile infrastructure.

NTT DoCoMo has the best coverage in Japan (although all Japanese mobile operators have basically perfect nationwide coverage).

With COMST, you do not get full access to the NTT DoCoMo network, but it is still extensive.

Below on the left, you have NTT DoCoMo's coverage and a coverage map for another NTT DoCoMo MVNO on the right produced by Speedtest:

COMST SIM has no eSIMs.

You can consider getting a travel eSIM for Japan, which can, in specific scenarios, be cheaper than getting a SIM card from COMST.

Especially if you get an Asia eSIM (for when you visit at least two or more supported Asian countries) or a global eSIM (for frequent travelers visiting multiple continents).

In my Japan eSIM buying guide, I analyze various eSIM options of eSIM providers I have tested extensively worldwide.

But I will introduce them here quickly:

  • Airalo: Moshi Moshi (Japan only), Asialink (14 countries in Asia) & Discover+ (130 countries worldwide + up to 200 worldwide minutes & 200 worldwide SMS) – use code NEWMAY15 (15% off – first-time users only) or AIRALOMAY10 (10% off)

  • Nomad: Japan, APAC (15 or 20 countries, depending on the variant), & Global (109 or 139 countries, depending on the variant) – use code ADU123 (3 USD off – first-time users only)

Once again, check out my Japan eSIM buying guide to learn more about these eSIM options.

Mobal Japan

Mobal Japan Logo
© Mobal Japan

Mobal Japan, just Mobal, is an NTT DoCoMo MVNO and a SoftBank Japan MVNO.

Surprisingly, it is one of, if not the only, MVNO allowing tourists to make calls (legally, of course).

How they manage to do it – I do not know… but it works!

Anyway, if you get the Mobal data-only SIM card, you will be on the NTT DoCoMo network (the best in Japan).

You will be on the SoftBank Japan network instead if you get the voice-enabled Mobal SIM card.

This is what you will learn about Mobal:

* Coverage

* Topping Up Options & Methods + Balance Check

Coverage – Mobal Japan

Mobal is an NTT DoCoMo and SoftBank Japan MVNO, meaning Mobal uses the NTT DoCoMo and SoftBank Japan networks and does not have its own mobile infrastructure.

NTT DoCoMo has the best coverage in Japan (although all Japanese mobile operators have basically perfect nationwide coverage).

With Mobal, you do not get full access to the NTT DoCoMo network, but it is still extensive.

In the case of SoftBank Japan, you should get full access, but that is not something I can confirm yet (I only got Modal's data-only SIM card, using NTT DoCoMo).

Below on the left, you have NTT DoCoMo's coverage and a coverage map for another NTT DoCoMo MVNO on the right produced by Speedtest:

SIM Card Price – Mobal Japan

You can get a Mobal SIM card for between 3990 JPY to 16 500 JPY online, and it can be picked up from various convenient locations, including at airports (Travelex), train stations & tourist information centers. Mobal SIM cards can be shipped for free to select destinations 1, allowing you to have your SIM card before going to Japan.

Note that Mobal is the only MVNO on this guide with a few voice-enabled SIM cards (using SoftBank Japan).

If you remember from earlier, SIM cards sold to tourists must be data-only because only nationals and those with a Japanese Residence Certificate (Jūminhyō – 住民票) can purchase voice-enabled SIM cards.

How Mobal manages to do this… I do not know, but it works!

Mobal has no eSIMs.

You can consider getting a travel eSIM for Japan, which can, in specific scenarios, be cheaper than getting a SIM card from Mobal.

Especially if you get an Asia eSIM (for when you visit at least two or more supported Asian countries) or a global eSIM (for frequent travelers visiting multiple continents).

In my Japan eSIM buying guide, I analyze various eSIM options of eSIM providers I have tested extensively worldwide.

But I will introduce them here quickly:

  • Airalo: Moshi Moshi (Japan only), Asialink (14 countries in Asia) & Discover+ (130 countries worldwide + up to 200 worldwide minutes & 200 worldwide SMS) – use code NEWMAY15 (15% off – first-time users only) or AIRALOMAY10 (10% off)
  • Alosim: Japan & Asia (five countries) – use code PTW (5% off – no limits)
  • Holafly: Japan & Asia (11 countries) – include unlimited data – use code PHONETRAVELWIZ (5% off – no limits)
  • Nomad: Japan, APAC (15 or 20 countries, depending on the variant), & Global (109 or 139 countries, depending on the variant) – use code ADU123 (3 USD off – first-time users only)

Once again, check out my Japan eSIM buying guide to learn more about these eSIM options.

Buying an eSIM for Japan Guide (logos of SimOptions, Nomad, Asialink, Discover+, Moshi Moshi, Holafly, Alosim & Airalo)

For now, I will continue with Mobal.

Note that NTT DoCoMo, the network Mobal uses, offers VoLTE (Voice over LTE (4G)) and VoWiFi (Voice over WiFi).

But as you can only get data-only SIM cards in Japan, the features will not be available to you 😓.

Note that NTT DoCoMo and SoftBank, the networks Mobal uses depending on the type of SIM card you have, offer VoLTE (Voice over LTE (4G)) and VoWiFi (Voice over WiFi).

But as you can only get data-only SIM cards in Japan, these features will not be available to you 😓.

Top-Up, Recharge & Balance Check – Mobal Japan

Mobal top-ups are sold by FamilyMart, Lawson & Ministop throughout Japan.

Note that the Mobal unlimited data-only SIM cards cannot be extended, and no credit can be added because it is unnecessary (which also means the SIM cards become deactivated after 8, 16, or 31 days).

However, the voice-enabled SIM cards are also long-term plans (which will be discussed in the next section), for which you can top up your SIM card (or pay for your plan online).

You can check your balance online.

Packages, Plans, Bundles & Offers – Mobal Japan

Mobal has only one data-featured prepaid plan: Japan Unlimited SIM Long Term Plans. it is a data bundle (without 5G NR access).

I will list all the prices in JPY (Japanese Yen).

To convert JPY to your currency (let's say HKD – Hong Kong Dollar) with up-to-date exchange rates, use the Wise Currency Converter tool.

It can only be added to the Mobal voice-enabled SIM cards (SoftBank Japan)

It is recommended to purchase a plan as early on in the month to get the most out of it because plans expire on the first of each month, regardless of when it was activated (even if it was done on the 28th (February), 29th (February leap year), 30th, or 31st.

These plans do not have call or SMS allowances, but you can call and text with them (after adding extra credit to your SIM card.

You will be charged 39 JPY/minute for local calls

International calls to Australia, Belgium, Canada, China, Denmark, Finland, France, Germany, Hong Kong, Indonesia, Ireland, Italy, Malaysia, the Netherlands, New Zealand, the Philippines, Russia, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, the United Kingdom & the United States) are charged at 65 JPY/minute

Nippon SIM for Japan

Nippon SIM Card for Japan Logo
© Nippon SIM (for Japan)

Nippon SIM for Japan, just Nippon SIM, is an NTT DoCoMo MVNO and a SoftBank Japan MVNO, depending on the SIM card you choose.

However, the SoftBank Network SIM card has only one option, so you will most likely be on the NTT DoCoMo MVNO instead.

This is what you will learn about Nippon SIM:

* Coverage
* How to Get a Nippon SIM SIM Card & SIM Card Price
* Topping Up Options & Methods + Balance Check
* Plans & Packages
* APN/Internet Settings

Coverage – Nippon SIM

Nippon SIM is an NTT DoCoMo and SoftBank MVNO (the latter for one starter pack only), meaning Nippon SIM uses the NTT DoCoMo MVNO network or SoftBank network and does not have its own mobile infrastructure.

NTT DoCoMo has the best coverage in Japan (although all Japanese mobile operators, including SoftBank, have basically perfect nationwide coverage).

With Nippon SIM, you do not get full access to the NTT DoCoMo network, but it is still extensive.

I believe you get full access to the SoftBank network if you get the SoftBank SIM card (but you cannot use its 5G NR access).

Below on the left, you have NTT DoCoMo's coverage and a coverage map for another NTT DoCoMo MVNO on the right produced by Speedtest:

Below is SoftBank's coverage map produced by Speedtest:

SoftBank Japan Coverage Map

SIM Card Price – Nippon SIM

You can get a Nippon SIM card for 1780 JPY to 7980 JPY from resellers, such as Askul, Bic Camera, & Yodobashi Central. They can also be delivered to the post offices in various airports, including the Tokyo ones, for 550 JPY. Delivery to your accommodation is free (up to five business days). International delivery is available too (for up to 10 000 JPY).

Nippon SIM has four different SIM card lines: SoftBank Network Plan, Unlimited Plans, Standard Plans & App Count Free Plans.

These SIM cards also act as plans for the Nippon SIM (which cannot be extended if you need more data).

Note that no Nippon SIM allows for 5G NR access.

The SoftBank Network Plan is the only Nippon SIM card that does not use the NTT DoCoMo network (for some reason).

It costs 1780 JPY and gives you 10 GB of data (without 5G NR access) until your SIM card expires.

The SIM card's expiry date is stated on the SIM card starter pack (often many months in the future), meaning you could use your allowance for months.

It is possible to get a Nippon eSIM for the same price as a regular SIM card.

You may want to get a travel eSIM for Japan, which can be cheaper than getting a SIM card from Nippon (in some cases).

Especially when getting an eSIM covering popular Asian destinations if you do not stay in just Japan or a global eSIM valid for up to a year if you want one eSIM to work practically worldwide.

My Japan eSIM buying guide analyzes various eSIM options of eSIM providers I have tested extensively worldwide.

Here is a quick introduction to them:

  • Airalo: Moshi Moshi (Japan only), Asialink (14 countries in Asia) & Discover+ (130 countries worldwide + call and text feature) – use code NEWMAY15 (15% off – first-time users only) or AIRALOMAY10 (10% off)
  • Alosim: Japan – use code PTW (5% off – no limits)
  • Holafly: Japan & Asia (11 countries) – these eSIMs have unlimited data – use code PHONETRAVELWIZ (5% off – no limits)
  • Nomad: Japan, APAC (up to 20 countries) & Global (up to 139 countries) – use code ADU123 (3 USD off – first-time users only)

For more information, such as the prices and data allowances, check out my Japan eSIM buying guide.
