Japan eSIM | Travel Data Plan with Instant Activation

Why use an eSIM in Japan?

1
Pocket Wi-Fi rentals are slow, expensive, and need to be returned at the airport — eSIM activates before you board your flight.
2
Convenience store SIM kiosks (FamilyMart, 7-Eleven) require Japanese ID and are not tourist-friendly.
3
Apps you actually need in Japan — Google Translate camera mode, Suica/Pasmo wallet, Google Maps transit, JR Pass reservations — all need constant data.

5G in Tokyo, Osaka, Kyoto, Fukuoka. 4G LTE nationwide including the Shinkansen network.

Install before takeoff
Activate the eSIM at home and switch it on the moment you land at Narita or Kansai. No queuing for SIM machines.
✓
Shinkansen coverage
Japan's bullet trains have continuous LTE through tunnels — you can stream from Tokyo to Kyoto without dropouts.
✓
Rural Hokkaido & Okinawa
Coverage is solid in tourist zones (Sapporo, Naha, Furano). Deep mountain trails and outer islands have spotty signal.
✓
Tethering allowed
Personal hotspot works — share your eSIM with travel companions to skip multiple plans.

Do I need to remove my home SIM to use a Japan eSIM?

No. Modern iPhones support dual SIM — keep your home number active for iMessage and calls while routing data through your Japan eSIM.

Will it work on the Tokyo subway?

Yes. Tokyo Metro and JR lines have full LTE coverage in stations and most tunnels.

Can I use it with Google Maps and Suica?

Yes. The eSIM gives you mobile data — every app on your iPhone works the same way it does at home.

Does it work for Apple Watch cellular?

No. eSIMs for travel are tied to your iPhone. Apple Watch cellular requires a separate plan from your home carrier.

What if I run out of data mid-trip?

Top up directly in the Beaver eSIM app — no need to buy a second plan or hunt for Wi-Fi.
