How is the free WiFi coverage in Japan? Which type of data card is recommended?

Free WiFi mainly covers areas

● Free WiFi at airport stations: Narita, Haneda, Kansai, Chubu, Fukuoka and other international airports offer free WiFi, registration is required (some require passport verification), internet speed is about 10-30Mbps, suitable for short-term transfers

● Urban convenience store hotspots: Tokyo: About 14% of WiFi in commercial areas such as Shinjuku, Shibuya, Ginza, etc. can be connected without encryption (such as Starbucks, 7-11), but the signal is unstable.

Recommended Japanese data cards

1. Short term tourists (3-5 days): Priority should be given to eSIM (such as SOFTBANK daily rental card), which is cost-effective and plug and play.

2. Medium - and long-term tourists (7 days+): Purchase Docomo tourist specific card, Docomo 30GB for 15 days, available at the airport, supports eSIM, and covers remote areas. Or rent a portable WiFi (with lower daily cost).

3. Emergency backup: Download "Google Fi" or "Airalo" eSIM to cover remote areas (credit card binding required in advance).
