Japan Wi-Fi Auto-connect is a free Android app that connects you to free Wi-Fi all over Japan. Once you download and register, you don't need to configure anything for any Wi-Fi spot. The app connects you automatically as soon as you reach a Wi-Fi spot, so you can use the internet right away. It notifies you via a pop-up message as soon as you are connected to free Wi-Fi.

This lightweight app conserves more battery power compared to previous apps and is easy to use. It allows you to use free Wi-Fi more easily, comfortably, and with peace of mind. The app does not connect you to unstable or weak networks and switches automatically to mobile internet in case the connection becomes unstable or weak. The app only connects you to those access points that are secure, trustworthy, and from reliable providers, avoiding the so-called "spoofing access points". The app also provides relevant information regarding the free Wi-Fi service coverage area, such as sightseeing information, shop services, disaster information, etc.

Japan Wi-Fi Auto-connect supports multiple languages, including Japanese, English, Korean, Chinese (simplified, traditional), Taiwanese, Vietnamese, Indonesian, Malay, Tagalog, French, Spanish, German, Italian, Russian, and Portuguese.
