Japan eSIM picks
Japan has excellent eSIM coverage. Nearly all major providers resell either Softbank or NTT Docomo capacity, so real-world speeds are uniformly good — the decision comes down to price and unlimited vs capped data.
At a glance
- Best general pick: Airalo — broadest Japan catalog, polished install, usually Softbank or KDDI
- Most Japan-native: Ubigi — its parent, Transatel, is an NTT subsidiary; deep partner relationships with Japanese carriers and pre-installed in some Japanese-market connected cars
- Best for streaming and video calls: Holafly Japan unlimited
- For travellers who’ll return: Dracotel — your balance carries to the next trip
Network notes
Japan’s three carriers — Softbank, NTT Docomo, and KDDI — all offer excellent nationwide LTE/5G coverage, including on the shinkansen. Whichever provider’s eSIM you pick, expect solid performance.
Practical tips
- Install the eSIM before you land. Narita and Haneda Wi-Fi can be flaky.
- Most eSIMs are data-only — no Japanese phone number. Use LINE for calls.
- Airalo’s Asialink regional plan covers Japan plus the rest of East/SE Asia.
