Travel eSIM guide
Why choose an eSIM for Japan?
Japan travel relies heavily on mobile data for train routing, station exits, translation, restaurant reservations and digital tickets.
Kyro lets you arrive with a prepaid data plan already installed, avoiding pocket Wi-Fi pickup counters and physical SIM swaps.
Install before you fly
Scan your QR code or use one-tap install while you are still on Wi-Fi at home.
Avoid roaming surprises
Prepaid data pricing means you choose the plan size before your trip.
Keep your main SIM
Use Kyro for data while keeping your usual number active for calls and apps.
How to choose a Japan eSIM plan
A smaller plan works for a short Tokyo visit with maps, messaging, translation and light browsing.
Choose more data for Shinkansen routes, photo backups, hotspot use, remote work or multi-city trips through Kansai and Hokkaido.
Where a Japan eSIM helps most
