About your Japan eSIM
Japan has world-class mobile networks but few free Wi-Fi hotspots that work without registration. A Japan eSIM keeps Google Maps, train route planners and translation apps working from Narita or Kansai onwards.
Coverage & networks in Japan
Near-total 4G coverage, including the Shinkansen and subway; 5G in Tokyo, Osaka and Kyoto.
Main mobile networks: NTT Docomo, SoftBank, KDDI (au). The network your eSIM uses depends on the plan.
Which plan for my trip?
- Weekend: 3 GB covers a short Tokyo stay with maps and messaging.
- One week: 10 GB suits a week of rail travel, translation and photo uploads.
- Two weeks +: Two weeks or more with a JR Pass, or heavy video use: choose 20 GB or unlimited.
Local tips for Japan
- Google Translate's camera mode uses data — great for menus and signs.
- Train route apps such as Navitime work best with live data.
- Japan plans are data-only; Japanese phone numbers are not included.
When you land in Japan
- Install the eSIM at home on Wi-Fi a day or two before you fly.
- After landing at Narita, Haneda or Kansai, switch mobile data to the eSIM and turn on data roaming for that line.
- Skip the pocket Wi-Fi counter — you are already online.

Japan eSIM FAQs
Do I need an eSIM for Japan?
An eSIM is the simplest way to get mobile data in Japan without roaming charges or buying a local SIM card. You install it before you travel and it connects when you land.
When does my Japan eSIM plan start?
The validity period starts when the eSIM first connects to a supported network in Japan, not when you buy it. You can install it at home a few days before departure.
Can I keep my own number in Japan?
Yes. JineSIM plans are data-only, so your regular SIM stays in your phone for calls and texts. Use WhatsApp, iMessage or FaceTime over data to stay reachable.
Is an eSIM better than pocket Wi-Fi in Japan?
For most travellers, yes. An eSIM has nothing to collect or return at the airport, no battery to charge, and every person in your group gets their own connection. Pocket Wi-Fi can still suit a large group sharing one device.
Can I use my Japan eSIM as a hotspot?
Most plans allow hotspot sharing, so you can connect a laptop or tablet. Check the plan details before buying.
Does the eSIM work on the Shinkansen and Tokyo subway?
Yes. Japan's networks cover bullet train routes and subway stations, with short gaps in some tunnels.
