Japan travel eSIM guide
Japan eSIM plans for tourists, trains and heavy data use
Choosing an eSIM for Japan usually comes down to the local network, high-speed data allowance, hotspot, validity and activation timing. Unlike a physical SIM card or pocket Wi-Fi, an eSIM can be installed by QR code before departure; current BambooSIM Japan plans are data-only and keep the live network, mobile-data and hotspot terms close to checkout.
Product facts worth comparing
- Plan choices
- Three plan families: unlimited data, one-time fixed-allowance bundles and SoftBank 90d plans with 30GB or 50GB. Check the selected speed option, hotspot allowance and activation instructions.
- KDDI/au network
- Unlimited and one-time KDDI plans connect directly through KDDI/au with a Japan IP and do not require data roaming. The 90d plans use local SoftBank 5G/4G; follow the selected plan setup instructions.
- QR setup and activation
- KDDI plans start on their first supported network connection in Japan. For SoftBank 90d plans, claim the QR code from your account when ready to use it; claiming starts the 90-day plan.
- Hotspot
- Hotspot is supported where the selected plan lists an allowance; unlimited on-device data does not mean unlimited tethering.
- Phone number
- BambooSIM Japan plans are data-only and do not include a Japanese carrier phone number. Use LINE, WhatsApp or another data-based calling app.
