Japan eSIM — How It Works

Planning a trip to Tokyo, Kyoto, or Osaka? Staying online in Japan is easy with an eSIM that runs on NTT Docomo, the largest mobile network in the country. Plans start at $2.99 for a 1GB/day day pass, and unlimited plans give you 1GB of full-speed data each day, then 5Mbps - plenty for maps, translation apps, and messaging.

Network & Coverage

Our Japan eSIM connects to NTT Docomo, whose 4G/5G network reaches from Hokkaido to Okinawa, including Shinkansen lines and rural onsen towns. Unlimited plans run at full speed up to 1GB per day, then continue at 5Mbps - enough for Google Maps, LINE, and web browsing.

Activation & Practical Info

The eSIM works from the moment you land at Narita, Haneda, or Kansai airports. Install the QR code over Wi-Fi before departure, then switch it on after landing. You keep your own number for calls and SMS while data runs on Docomo.

Where you'll use it — Japan eSIM

Land at Narita or Haneda and you're online before baggage claim. Stream maps on the Shinkansen between Tokyo and Kyoto, post Mt. Fuji shots from Fuji Five Lakes, and navigate Osaka's Dotonbori without hunting for pocket WiFi - NTT Docomo covers the rural onsen towns too.
