Internet in Japan
Fast, reliable, and cheap — if you pick the right option before you land.
Japan has excellent mobile coverage virtually everywhere — trains, rural areas, underground stations. The network is there. The question is just how you access it.
Three options work well for tourists: eSIM, pocket WiFi, or a local data SIM. Each has trade-offs.
Your options
Recommended
eSIM via Airalo
The simplest option if your phone supports eSIM. Buy before you fly, activate on arrival, and skip the SIM card hassle. Airalo offers Japan data packages starting from €3.50 for 1 GB — reliable and widely used.

Pocket WiFi
A portable router you rent and return at the airport. Connects multiple devices — useful for groups or if your phone doesn't support eSIM. Requires picking up and returning at a rental desk.
Data-only
Local data SIM
A physical SIM for your phone. Widely available at airports and convenience stores. Works well, but doesn't include calling — data only. You'll need an unlocked phone.
Good to know
Coverage is excellent
Japan's mobile networks (Docomo, SoftBank, au) cover almost the entire country including rural areas and most subway systems. Dead zones are rare.
Free WiFi is patchy
Most hotels, many cafes and convenience stores offer free WiFi, but it's inconsistent and often requires registration. Don't rely on it as your primary connection.
Buy before you land
Setting up an eSIM or ordering pocket WiFi before departure is faster and usually cheaper than buying at the airport on arrival.
Check eSIM compatibility
Most modern iPhones (XS and later) and many Android flagships support eSIM. Verify your device supports it before purchasing.
Speeds are fast
LTE and 5G coverage is widespread. Even budget data plans deliver speeds fast enough for navigation, messaging, and video calls.
Note
Prices and plan availability change regularly. Check the provider's site for current options before purchasing.
