Japan's Three Great Flatland Castles refer to three representative castles built on plains, generally considered to be Nijo Castle in Kyoto, Matsumoto Castle in Nagano, and Hiroshima Castle in Hiroshima. These castles developed together with castle towns and remain historic sites with preserved tenshu towers, palaces, stone walls, and moats. Visitors can learn about Japanese history through exhibitions and guided tours inside the castles, while also enjoying walks around the surrounding towns and cultural experiences. They are iconic destinations for travelers to experience Japan's castle culture.
