What you'll actually connect to

Real networks. Real speeds.

NTT Docomo offers extensive coverage in urban areas like Tokyo and Osaka, making it reliable for city travelers. SoftBank, while strong in cities, also excels in suburban areas. Both carriers provide excellent indoor and outdoor connectivity, though rural coverage may vary slightly with NTT Docomo leading in more remote regions.

Plan your usage

How much data do you need in Japan?

A rough guide to pick the right plan — your real usage depends on how much you stream and share.

Light
~1 GB / week

Maps, messaging, email and the occasional search. Enough to stay oriented and in touch.

Medium
~3–5 GB / week

Social feeds, browsing, music and some video. The sweet spot for most travelers.

Heavy
10 GB+ / Unlimited

Video calls, lots of streaming and tethering your laptop or sharing a hotspot.

Why eSIM for Japan

Skip the SIM shop. Save the roaming charges.

Roaming on your home carrier in this country gets expensive fast. A local SIM means broken Apple Wallet, hunting kiosks at the airport, and 30 minutes lost to a registration form. eSIM activates in the time it takes to find your hotel.
