A Japan eSIM is a prepaid data plan that connects your phone to local Japan networks the moment you land — a digital SIM you install before you fly, with no queues, no SIM swap and no roaming fees.
Arriving at Tokyo's Narita International Airport? Step into the terminal already online instead of queuing for a SIM. Your Japan eSIM activates as you reach the gate, so you can map the train into the city, message home, and look up your hotel before you collect your bags. Coverage follows you from Tokyo's neon to the temples of Kyoto and the snow country around Sapporo.

Frequently asked questions
Which eSIM is best for Japan?
Pick the data amount and validity that match your trip. A small plan covers a few days of maps and messaging; choose a larger plan for longer stays or heavy use. You can top up any time.
Can I keep using my number while using an eSIM in Japan?
Yes. Your physical SIM stays in your phone for calls and texts on your usual number, while the eSIM carries your data. Most recent phones support using both at once.
Can I use a hotspot with my eSIM in Japan?
On most phones, yes — you can share your eSIM data over a personal hotspot. Just enable hotspot or tethering in your phone's settings.
When should I activate my eSIM for Japan?
Install the eSIM at home over Wi-Fi before you travel, then turn the data line on when you arrive in Japan. Data is only used once it connects to a local network.
Do I need an eSIM-compatible phone?
Yes — your phone needs to support eSIM and be carrier-unlocked. Most phones from the last few years qualify; look for an 'Add eSIM' option in your settings.
Is this eSIM data-only?
Yes, these plans are data-only. Use internet-based apps like WhatsApp, Viber or FaceTime for calls and messages over the data connection.
