FAQ

Japan eSIM Questions

The stuff people actually ask me.

What 4G coverage can I expect in Tokyo? +

Tokyo has extensive 4G coverage from KDDI, especially in central wards like Shibuya, Shinjuku, and Minato. Osaka, Nagoya, and Fukuoka also have strong 4G. Rural areas connect via fast 4G/LTE.

Does eSIM work on the Shinkansen bullet trains? +

Yes. Major Shinkansen routes including Tokyo-Osaka, Tokyo-Kyoto, and Tohoku lines have solid 4G coverage. Speeds may dip briefly in tunnels, but you will stay connected for most of the ride.

How do I activate my Japan eSIM? +

Scan the QR code delivered to your email (or provision via API), connect to the local network, and data starts immediately. No store visits, no physical SIM swaps, no waiting.

Will my eSIM work on remote Japanese islands? +

Coverage is excellent across mainland Japan and major islands including Okinawa, Hokkaido, and Kyushu. Smaller remote islands may have limited coverage, but all popular tourist destinations are well served.
