Free Wi-Fi in Japan — Complete Comparison: Quick Answer Guide to Airports, Stations, Cafés, and Convenience Stores
⚡ The 30-second answer: Japan's six main free Wi-Fi systems = ①Japan Connected-free Wi-Fi (official aggregator) ②Airport Wi-Fi (Narita / Haneda / Kansai, 24h) ③Convenience store Wi-Fi (7SPOT / Lawson Wi-Fi) ④Café Wi-Fi (Starbucks / Doutor / Tully's) ⑤Station Wi-Fi (JR-East Free Wi-Fi / Tokyo Metro) ⑥Tourist information center Wi-Fi. Speeds 5–30 Mbps, sign-in in 30 seconds, and pairing it with an Airalo eSIM is the strongest combo.
Japan has one of the world's best free public Wi-Fi networks, and an official integrated app is provided for tourists. However, speed and reliability still lag behind eSIMs and pocket Wi-Fi, so it's best to secure a separate primary connection.
