Japan travel eSIM: what to know
An eSIM for Japan is a prepaid, data only mobile plan that you download to your phone before the trip and that connects to Softbank, KDDI, Rakuten when you arrive. eSIMTrip sells 20 plans for Japan, from $2.40 for 1GB, 3 days.
Traveling in Japan
Japan attracts tourists for its mix of modern cities and traditional culture. Visitors often explore Tokyo, Kyoto, and Osaka, with trips lasting from a week to a month. Mobile data is essential for navigating public transport, translating Japanese signs, and booking tickets for attractions like Mount Fuji or the Shinkansen bullet train. Apps like Google Maps and Japan Travel by Navitime are widely used for planning routes and finding local spots.
Coverage and signal
Mobile coverage in Japan is strong in cities and along major train routes. However, signal can be weaker in mountainous areas like the Japanese Alps or remote islands such as Hokkaido's northern regions. Travellers heading to rural areas like Shirakawa-go or Yakushima should download offline maps beforehand. Japan's public Wi-Fi is reliable, but having a data eSIM ensures seamless connectivity for apps like Uber Japan and local transit tools.
Choosing the right plan
For short city breaks in Tokyo or Osaka, a 3-day plan with 1GB or 3GB is sufficient. Longer trips exploring multiple regions may require a 10GB or 20GB plan valid for 15 or 30 days. Heavy users streaming videos or using navigation frequently can opt for unlimited data. Choose a plan that matches your itinerary and data needs, ensuring coverage across Softbank and KDDI networks.

FAQs for your travel eSIM
Frequently asked questions
Which network does the Japan eSIM use?
It connects to Softbank, KDDI, Rakuten in Japan, on 5G where your phone and the area support it and 4G LTE elsewhere.
How much is an eSIM for Japan?
Plans start at $2.40 for 1GB, 3 days. There are 20 plans from 3 days to 30 days, including unlimited plans for 3, 5, 7, 10, 15, 30 days. Prices are in US dollars and final.
Does the Japan eSIM include a phone number?
No, it is data only. Keep your home SIM on for calls and texts, and use apps such as WhatsApp or FaceTime over the eSIM data while you are in Japan.
When should I install my eSIM for Japan?
Install it on WiFi a day or two before you leave. The plan's days only start when the eSIM first connects in Japan, so nothing is lost by installing early.
Can I top up the Japan eSIM?
Yes, this eSIM can take another plan for Japan. You can also simply buy a second plan, which arrives as a new eSIM with its own QR code.
Can I use the eSIM for Japan in other countries?
It works in Japan only. If your trip continues to neighbouring countries, a regional plan covers Japan and the others on one eSIM.
When should I install my eSIM?
Install it one or two days before you leave, on a stable WiFi connection. On arrival you only switch the eSIM line on and turn on data roaming for it. Installing early does not start the validity period.
Where do I find the QR code?
Right after the purchase the eSIM appears in My eSIMs with its QR code, the SM-DP+ address and the activation code. If you only have one phone, copy the address and code and enter them by hand in the phone's eSIM settings.
Can I reinstall an eSIM I deleted?
Usually not. Most eSIM profiles can be downloaded once, so a deleted eSIM cannot be added again with the same QR code. Switch the line off instead of deleting it until your trip is over.
What do I do if I run out of data?
Buy another plan for the same destination and install it as a new eSIM; it takes about two minutes on hotel WiFi. Your phone can store several eSIMs and you choose which one carries data.
Which plan should I choose for several countries?
If all the countries are in one region, a regional plan such as Europe (41 countries) or Asia keeps you online across borders with one eSIM. If your trip crosses continents, the global plan covers 161 countries with a single eSIM.
Why can't I connect after landing?
Check that the eSIM line is on, that it is selected for mobile data and that data roaming is on for it. Then switch airplane mode on and off. If it still does not connect, pick the partner network shown on the destination page manually in the carrier settings.
Can I buy eSIMs for my family?
Yes. Choose a quantity from 1 to 100 at checkout. Every eSIM gets its own QR code, so each person installs one on their own phone.
How do I pay?
You pay for eSIMs from your account credit. Add credit from $30 with USDT (TRC20, BEP20, ERC20, Solana), USDC, BTC, ETH, BNB, SOL or LTC in the secure PayGate checkout that opens on the site. TRON USDT usually confirms in about a minute.
How do I create an account?
Press Get started. Your browser creates an account token that starts with ESM. Copy it or save it as a .txt file, tick the box and the account opens. The token is your login and your password at once, so keep it somewhere safe; there is no email or password to reset.
How do refunds work?
An eSIM that was never installed (within 30 days of purchase) or that never connected at the destination is refunded to your account credit. Credit stays in your account for your next eSIM; it is not paid out to a wallet.
Are the prices final?
Yes. Prices are in US dollars and include everything; what you see on the plan is what is taken from your credit. Network fees for your crypto top-up are shown in the checkout before you pay.
How are prices set?
We compare every plan with the public price of a leading travel eSIM seller for the same data and days, and sell it 40% lower. The comparison was last read on 4 November 2026.
Is my payment information stored?
No card data is involved. We keep your credit balance, your top-up records with the blockchain transaction id, and the eSIMs you bought. Your IP address is not stored in plain form.
