Best eSIM & SIM Cards for Japan Travelers in 2026
Japanese eSIM/SIM Cards Explained
In Japan, there are two main options for getting connected:
- Voice + Data Plans
- Data-Only Plans
Here's a quick breakdown of each:
| Option | Voice + Data | Data-Only |
| eSIM Available? | Yes | Yes |
| Phone Number | Yes | No |
| Internet Access | Yes | Yes |
| SMS/Texting | Yes | Yes |
| Best For | Regular smartphone use | Tablets, mobile hotspots, or no need for a phone number |
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM that lets you activate your mobile service without inserting a physical SIM card. Instead of swapping plastic SIMs, you simply scan a QR code and download your plan directly to your device.
You can choose:
- A Voice + Data Plan (with a Japanese phone number)
- A Data-Only Plan (no phone number)
Whichever plan you choose, you can enjoy the same services as with a traditional physical SIM card, including internet access, texting (SMS), and a Japanese phone number.
*International SMS & Japanese phone numbers are only available for Voice + Data plans.
Voice + Data Plans
A Voice + Data plan includes a Japanese phone number along with mobile internet access. This is the closest equivalent to a standard mobile plan you might use in your home country.
This option is ideal for long-term residents who need both voice and data services and will often use their local Japanese number for everyday communication as well as essential tasks such as opening a bank account, completing government or administrative procedures, securing housing, or contacting local services.
Data-Only Plans
A Data-Only plan offers internet access and texting (SMS) but does not provide a phone number. This option is typically used for devices like tablets, mobile hotspots, or in situations where you don't need a phone number. Unless you have a specific need for a Data-Only SIM/eSIM, we recommend a Voice + Data SIM/eSIM, as a Japanese number will likely be more useful for day-to-day life.

Best eSIM/SIM Cards in Japan – Quick Comparison
When choosing a long-term mobile plan in Japan, it helps to compare leading providers side by side. Today, eSIM plans are widely supported across major carriers and many MVNOs, including Sakura Mobile. This updated chart reflects that reality, with an emphasis on the options that meet your needs.
Before you take a look at each plan, here are some important questions to ask yourself:
- How much data do I get each month?
- How much does it cost?
- How fast is the internet?
- Where can I use it in Japan?
- Can I get English support when I need it?
Checking these things will help you find the right SIM card or eSIM for you.
| Provider | eSIM Option Available | Voice + Data Plan | Typical Monthly Cost (Estimate) | Data Options | English Support | Best For |
| Sakura Mobile | Yes | Yes | 3,278 yen – 4,378 yen | 5 GB–30 GB (larger options available) | Full English customer support | Residents wanting support in English |
| Rakuten Mobile | Yes | Yes | From 1,078 – 3,278 yen | Tiered (e.g., 3 GB, 20 GB, unlimited) | English AI support chatbot available | Affordable option with basic English help |
| docomo | Yes | Yes | 5,698 yen – 8,448 yen | Unlimited plans available | Limited English resources, primarily Japanese support | Best coverage nationwide |
| SoftBank | Yes | Yes | 3,465 yen – 7,238 yen | Unlimited options (5G) | Limited English support | Strong network quality |
| au | Yes | Yes | 3,465 yen – 7,238 yen | Unlimited options available | Some English info but mostly Japanese support | Great high-speed coverage |
Notes on English Support:
- Sakura Mobile is the standout choice for English-speaking residents. They provide full English support (in person at their Shinjuku office, airport counter help at Kansai and Fukuoka airports, email, phone, and live chat) — from phone support to billing and plan management, everything is available in English. Whether you need help with your account, setting up a plan, or addressing issues that arise, you'll have access to dedicated support every day of the week.
- Rakuten Mobile offers English phone support, making it a solid choice for those who prefer English assistance. However, Rakuten's English support is somewhat limited compared to Sakura Mobile, as it primarily relies on a phone line and offers only some online resources in English.
- NTT docomo, au, and SoftBank provide some English-language resources online, including basic plan details and customer service numbers, but the support experience is more limited compared to MVNOs. Most of their in-store or detailed plan assistance is primarily in Japanese, with English assistance being more limited and not as readily available across all locations.
Major Carriers vs MVNOs
In Japan, major carriers like docomo, au, and SoftBank operate their own networks, which means strong coverage and high speeds, but generally higher prices. These carriers also offer more traditional mobile plans with contracts, and often, customer service is in Japanese.
On the other hand, MVNOs (mobile virtual network operators) such as Sakura Mobile and Rakuten Mobile (which is also its own provider or MNO) lease access to these major carrier networks offering affordable plans with flexible terms. While network speeds may vary depending on usage and location, MVNOs offer great value for long-term residents who prioritize flexibility and cost savings.
Why Sakura Mobile Is the Best Choice
For long-term residents staying in Japan for more than 90 days, Sakura Mobile offers a perfect blend of affordability, reliability, and full English support. Here's why:
- Balanced Data Plans: Plans like 5 GB for around 3,278 yen/month and 30 GB for 4,378 yen/month give you options depending on your usage.

- Reliable Networks: Sakura Mobile runs on Japan's top carrier network (docomo), ensuring nationwide 4G LTE and 5G coverage (where available).

- No Contract Commitment: Enjoy flexibility with no long-term contract required so that you can adjust your plan as your needs change.
How Much Data Do You Really Need?
Choosing the right data plan comes down to how you use your phone each day. Some people mostly text and check maps. Others stream video, join online meetings, or use a hotspot for work.
Here's a simple guide to help you decide.
| Usage Type | Typical Activities | Estimated Monthly Data Use | Best Sakura Plan Range |
| Light | Messaging apps, email, maps, light browsing | 3 GB–5 GB | 5 GB plan |
| Moderate | Social media, music streaming, short videos, regular browsing | 10 GB–15 GB | 15 GB plan |
| Heavy | HD video streaming, frequent video calls, tethering occasionally | 20 GB–30 GB | 30 GB plan |
| Very Heavy | Remote work, daily video meetings, hotspot use, large downloads | 40 GB–100 GB | 40 GB–100 GB plans |
These are general estimates. Actual usage depends on how often you stream video, use hotspot, or download large files.
Light to Moderate Users
If you mainly use your phone for messaging, navigation, and checking social media, the 5 GB or 15 GB plans are usually enough.
Many long-term residents with home WiFi fall into this category. You'll use mobile data while commuting or running errands, but not all day.
Heavy Users
If you regularly stream HD video, take video calls, or use tethering sometimes, the 30 GB plan offers a comfortable buffer.
This is a popular choice for residents who spend a lot of time outside the home or rely on mobile data throughout the day.
Very Heavy Users (40 GB–100 GB)
If you work remotely, use a hotspot daily, attend frequent online meetings, or stream in high definition often, you may need 40 GB or more.
Sakura Mobile offers larger plans ranging from 40 GB up to 100 GB, giving you flexibility without locking you into a long-term contract. This makes them a strong alternative to major carriers if you want high data without high pressure.

How to Get Your eSIM/SIM Card
Once you've decided on your ideal eSIM or SIM card plan, the next step is getting your card and getting connected. Here's everything you need to know about the process to ensure a smooth start to your stay in Japan.
Ordering Your eSIM or SIM Card
The easiest way to get your eSIM or SIM card in Japan is to order it in advance. You can purchase your plan online through Sakura Mobile's website, where you can choose from a range of options that fit your data needs and budget. If you opt for an eSIM, the activation process is even more convenient — there's no need to wait for a physical SIM card to be shipped.
However, depending on the identification document you use and where you're applying from, the process may not be entirely online.
Due to strict Japanese telecommunication laws, identity verification requirements are carefully enforced.
If you apply for a Voice + Data eSIM using a passport (or any ID that does not display your current Japanese address), you will be required to select a physical pickup location. In this case, the process cannot be completed entirely online, and a face-to-face ID check will be conducted when you pick up your activation envelope.
Your eSIM application can be completed entirely online if your online identity verification is successfully approved using a valid ID with your registered address.

Airport Pickup
If you're arriving in Japan and want to pick up your SIM card at airport, you can do so at Narita, Haneda, Fukuoka or Kansai International Airport. Simply reserve your SIM card or eSIM envelope online at least a week before your trip, and then head to the Sakura Mobile counter at the international arrivals terminal to collect it.
For more details on how the pickup process works, be sure to check out this video from 0:49 onward. It shows exactly how to pick up your Voice + Data SIM or eSIM envelope, and the proccess is the same for long-term residents and short-term visitors alike.
eSIM Activation
If you've chosen an eSIM, the setup process is simple and quick. After you've purchased your plan and received your activation details, follow the instructions to install the eSIM profile on your device. With eSIM, you don't need to worry about inserting a physical SIM card — just activate it directly from your phone or tablet.
Where to Get Help
If you need assistance at any stage, whether it's activating your eSIM or managing your plan, Sakura Mobile offers dedicated English support. You can reach out through their customer service channels for help with setup or any questions about your service while in Japan. Unlike some other providers, Sakura Mobile provides full English support, whether in person at their Shinjuku office, airport counter help at Kansai and Fukuoka airports, email, phone, or live chat, so you can get assistance wherever you need it, without worrying about language barriers.
Important Points to Remember
- Order early: Make sure you order your SIM card or eSIM at least a week in advance if you plan to pick it up at the airport.
- Choose your airport pickup: If you prefer to pick up your SIM card upon arrival, be sure to select Narita, Haneda, Fukuoka, or Kansai International Airport when booking online.
- Check activation details: If you've opted for an eSIM, follow the activation instructions carefully to get connected as soon as possible.
If you plan ahead, you can skip the hassle and start using your phone in Japan as soon as you step off the plane!
SIM Card FAQ
- What Is a SIM Card?
A SIM (Subscriber Identity Module) card connects your phone to a mobile network. With a Voice + Data plan, it allows you to make calls, send SMS, and use mobile data.
There are two main types:- Physical SIM card – A small chip you insert into your phone.
- eSIM – A digital SIM that you download directly to your device. No physical card required.
Both options let you connect to a Japanese mobile network. The main difference is how they are installed. With an eSIM, everything is done online, which makes setup faster and easier for many long-term residents.
- Will My Foreign Phone Work With a Japanese eSIM or SIM Card?
In most cases, yes — but your device must meet two requirements:
- SIM-free (unlocked)
- Compatible with Japanese network bands
Japan's major carriers — docomo, au, SoftBank, and Rakuten Mobile — use 4G LTE and 5G bands that most modern smartphones support. iPhones released in recent years, as well as many Android flagship models, are compatible.
If your phone is locked to a carrier in your home country, you'll need to unlock it before using a Japanese SIM or eSIM.
If you're unsure, Sakura Mobile provides compatibility pages where you can check:- Travel SIM & eSIM compatibility
- Long-Term SIM/eSIM compatibility
- How to check if your device is locked or SIM-free
- Japan Pocket WiFi rental compatibility
You can also contact Sakura Mobile's English support team if you want help checking your device.
- Do I Need a Residence Card for a Long-Term Plan?
Yes. For long-term Voice + Data SIM or eSIM plans in Japan, providers require:
- A valid residence card
- A Japanese address
- A valid payment method
This applies to major carriers and most MVNOs. Some providers may also require identity verification (eKYC) during the application process.
Sakura Mobile makes this process simple and provides full English support.- Is eSIM Better Than a Physical SIM?
For many long-term residents, yes.
An eSIM allows you to:- Activate your service online
- Avoid waiting for shipping
- Use dual SIM functionality (keep your home number active)
- Switch plans more easily
That said, a physical SIM works just as well if your device does not support eSIM.
Both options offer the same network quality when running on the same carrier network.- Where Can I Get Help in English?
English support varies widely by provider.
- Major carriers like docomo, au, and SoftBank have English websites, but in-store and detailed billing support is usually in Japanese.
- Rakuten Mobile offers an English phone support line, but service options may be more limited.
- Sakura Mobile provides full English customer support seven days a week, including billing help, plan changes, and troubleshooting.
If having reliable English support matters to you, this something to weigh carefully.
For more answers, you can always visit the Sakura Mobile FAQ page or contact the support team directly.
