Japan eSIM from $1.49 — 4G on NTT Docomo, SoftBank & KDDI (au)

Yes, our eSIM connects to the NTT Docomo, SoftBank and KDDI (au) networks, which provide reliable coverage along all Shinkansen routes, including tunnels. You will have uninterrupted data for maps, streaming, and messaging throughout your journey between Tokyo, Osaka, Kyoto, Hiroshima, and Hakata.

Absolutely. Our partner networks cover all Tokyo Metro, Toei Subway, and JR lines underground. You can use Google Maps or Japan Travel apps to navigate subway stations in real time. Some deep platforms and older tunnel sections may have brief interruptions.

Significantly. Portable WiFi rental costs $5–$12 per day plus a deposit, requires pickup/return at the airport, and needs daily recharging. Our Japan eSIM costs from $1.49 for the entire trip, works immediately on landing, and requires no pickup line, no deposit, and no charging.

Coverage extends to the base of Mount Fuji (Fujisan Station area), Hakone, Nikko, and most major national parks. At the summit of Mount Fuji and deep rural trails, coverage becomes sporadic. We recommend downloading offline maps before heading to remote areas.

Most Japanese-market phones sold since 2021 (SIM-free models) support eSIM. Some carrier-locked phones from Docomo, au, or SoftBank may have restrictions. Check if "Add eSIM" appears in Settings > Cellular. SIM-free iPhones and recent Google Pixel and Samsung models work without issues.

Our eSIM is data-only, so direct cellular calls are not supported. Use WhatsApp, FaceTime, Skype, or LINE for voice and video calls over data. Most cafes, hotels, and restaurants in Japan offer free WiFi for backup.
