Japan is not the place to arrive without mobile data
Japan is easy to travel, until you lose internet. Train transfers, hotel addresses, restaurant reservations, QR menus, translation apps and taxi pickup points all become harder without reliable data. A Japan eSIM lets you install your plan before departure and connect as soon as you land.
Instead of wasting your first hour at Narita, Haneda, Kansai or Fukuoka Airport looking for a SIM card or pocket Wi-Fi rental desk, you get the link to your eSIM by email, install it with one tap and keep your own phone number active while using mobile data in Japan.

Comparison
Japan eSIM vs pocket Wi-Fi vs roaming
Pocket Wi-Fi used to be popular in Japan, but it is outdated for most travelers. You have to pick it up, charge another device, return it and carry it everywhere. An eSIM is cleaner, faster and already inside your phone.

Travel Use Cases
Why unlimited data matters in Japan
Japan is one of the worst destinations to “just rely on Wi-Fi.” Public Wi-Fi is inconsistent, train stations are busy, addresses can be confusing and many travel moments happen while you are moving.

FAQ
Japan eSIM questions travelers ask before buying
AeroSims is a strong choice for travelers who want unlimited data on their phone in Japan, a local Japanese network instead of roaming, delivery by email and no physical SIM card. It is especially useful for Tokyo, Kyoto, Osaka, Hiroshima, Sapporo, Fukuoka and longer Japan rail trips.
Yes. The Japan eSIM is designed for travel across major Japanese cities and tourist routes including Tokyo, Kyoto, Osaka, Nara, Hiroshima, Sapporo, Fukuoka and Okinawa. Signal quality can vary in remote mountains, tunnels or underground areas, just like with any mobile network.
Yes, up to a total amount for your whole plan; the amount for each duration is in the hotspot table. After that only the hotspot can slow down, your phone keeps going. Tablets and laptops on the hotspot use up the amount faster than a single phone.
Yes. Install your eSIM before departure while you still have stable Wi-Fi. That way, when you land at Narita, Haneda, Kansai, Chubu or Fukuoka Airport, you can turn on your Japan eSIM and connect immediately.
For most solo travelers and couples, yes. A Japan eSIM does not require pickup, charging, carrying or returning an extra device. Pocket Wi-Fi can still make sense for larger groups, but for convenience, an eSIM is cleaner.
No. You do not need to show your passport or register at an airport service desk. After purchase you get an email with the link to your eSIM page, where you install the eSIM on your compatible phone.
Your phone must support eSIM, be unlocked and support LTE Band 18 or Band 26. Check your exact model, not just its name: our device list shows eSIM support, and the bands are in your model's technical specs.
Yes. Your Japan eSIM gives you mobile data for apps like WhatsApp, Instagram, TikTok, Google Maps, Apple Maps, Uber, hotel apps, translation apps and online banking.
Your eSIM uses a local Japanese mobile network instead of roaming, on 4G and on 5G where your phone and the network support it. Your traffic exits in Japan: you get a Japanese IP address. Speed and signal depend on location, time of day, network load, buildings and your phone, and are not guaranteed. A fair use policy applies.
