eSIM for Japan
Land in Japan already connected — on real Japanese networks, no pocket WiFi to rent or return.
The Shinkansen out of Tokyo, the lantern-lit lanes of Kyoto, a ramen counter in Osaka you found three minutes ago — Japan moves fast and rewards travellers who are already online. A Wyra eSIM for Japan connects you the moment you land at Narita, Haneda or Kansai: translation app ready, IC card topped up, Google Maps guiding you through stations that genuinely need it.
For years the answer here was renting a clunky pocket WiFi and returning it before your flight. An eSIM does the same job — on the same Japanese carriers — with nothing to carry, charge or hand back. Coverage in Japan is excellent, dense in the cities and strong along the rail lines, and we'll always tell you exactly how much full-speed data you've got. Just note: Japan's plans run a little differently from our European ones, so check the ladder below.
Real networks
Your data runs on NTT Docomo, KDDI (au) and SoftBank — Japan's top-tier carriers, the same networks the pocket-WiFi boxes use. 5G is available on select networks (KDDI (au) and SoftBank) where you see it; elsewhere you're on fast, dependable 4G/LTE.

Buy your Japan eSIM
What “unlimited” really means
Japan has one unlimited option, and we're straight about how it works:
- Unlimited Max — full speed for 3 GB/day, then 256 kbps for the rest of the day.
The full-speed allowance resets daily — no hard cutoff mid-trip. Doing constant navigation and translation across multiple cities? A larger fixed plan can actually give you more sustained full speed than the unlimited tier — compare both above.
How much data do you need?
- Light: 1–3 GB for a few days in Tokyo.
- Normal (maps, translate, social): 5–10 GB for a one-to-two week itinerary.
- Heavy (video calls, streaming on the Shinkansen, lots of translation): 20–30 GB+.
Japan makes you lean on data — live translation, transit routing and maps run constantly. Most travellers underestimate; size up one tier.
Japan eSIM — FAQ
Which Japanese networks does it use?
It connects to NTT Docomo, KDDI (au) and SoftBank — the country's premium carriers.
Is this better than renting pocket WiFi?
For most solo and couple travellers, yes: same networks, no device to charge or carry, nothing to return at the airport. Pocket WiFi still makes sense for big groups sharing one connection.
Will it work in rural Japan and on the Shinkansen?
Yes — coverage is strong nationwide and along rail lines. Deep mountains and remote Hokkaido can still thin out for any network.
Why are Japan's plans different from your Europe plans?
Different wholesale market — so the data sizes, validity and unlimited tier are structured for Japan specifically. The honesty is the same; the ladder isn't.
