ニッポン城めぐり -城の位置ゲーム/位置情報×歴史ゲーム

Nippon Castle Tour is a location-based castle game that uses GPS to help you visit about 3,000 castles across Japan from the Sengoku era. Explore castle data, photos, and reviews (tallying over 50,000 reviews and 400,000 photos) and enjoy engaging features like a Sengoku warlord collection, Castle Lord rankings, and a Castle Construction mode. The game also includes a Castle Attack stamp rally mechanic, a daily History Quiz, and other long-term features for history lovers and travelers alike.

In addition to the core game, the app runs regional and limited-time campaigns in collaboration with local governments, including JR Central and prefectural projects. Campaigns highlight castles and related spots in Nagoya, Kani, Nagano, Tsuyama, and northern Omi. It also supports sending castle locations to car navigation apps via NaviCon, making it useful for planning trips while learning about Japan's history.
