From Tokyo to Kyoto
Whether you're changing trains in Tokyo, walking the temple lanes of Kyoto or heading down to Osaka, a data eSIM keeps route planners, timetables and translation apps at hand. It's the difference between guessing at a platform and knowing which train, carriage and exit you need.
Ready before departure
Install the eSIM while you're still at home and there's nothing left to sort out on the day. Skip the SIM counters at the airport, scan the QR code once, and turn the plan on when you land so your data starts exactly when your trip does.
How much data to choose
For maps, messaging and the odd search, a lighter plan usually lasts a two-week trip. If you'll be streaming, sharing photos or tethering a laptop between cities, a larger allowance is the calmer choice. You can always add another eSIM if you run low.
FAQ
Does an eSIM work on the bullet train and in rural areas?
A travel eSIM uses local mobile networks, so it works wherever your phone would normally find a signal — on fast trains between cities and in most towns you'll pass through. Signal can dip in deep tunnels or remote hills, as with any phone.
Can I use it as soon as I land at the airport?
Yes. If you've added and activated the eSIM, data is usually working by the time you reach the arrivals hall, ready for maps and train bookings before you've left the terminal.
Will my number still work in Japan?
Your home SIM stays in the phone, so your number keeps working for calls and texts if you leave it switched on. Most travellers keep roaming off on that line and let the eSIM carry all their data.
