Japan eSIM Data Speed
Your data breaks out inside Japan itself, so it never leaves the country to reach the internet. No detour, no added latency — streaming, video calls, maps and gaming all run exactly as they would on a local SIM.

About eSIMs in Japan
Choose a Japan eSIM for trips lasting from 1 to 30 days, with data options ranging from 1GB to 50GB. Unlimited data is also available, so you can match the plan to your itinerary and how often you expect to use mobile data.
Coverage & networks
This eSIM connects to NTT docomo’s 4G network in Japan. It is a data-only service, so calls and texts are not included. Use data-based apps for maps, messaging and travel information while you are in Japan.
How much data you need
Available allowances include 1GB, 3GB, 5GB, 10GB, 20GB and 50GB, with unlimited data also offered. Light use such as maps and occasional messaging may suit a smaller allowance, while frequent streaming, video calls or hotspot use may require more data or an unlimited plan. You can top up if you need additional data during your trip.
Setting it up
Select a plan length and data allowance that suit your stay, then follow the setup instructions for your device. Check that your phone supports eSIM before purchase and complete the installation when prompted. Once activated, use the eSIM for mobile data in Japan.
