Situated at the summit of the 400 m high Mt. Kinojo, these ruins, which include about 2.8 km of stone walls and earthwork, are all that remain of the original castle built more than 1300 years ago. The size and structure of the ruins suggest the castle was one of Japan’s largest. The paving stones found inside and outside the castle walls were not found in any other fortress in ancient Japan. Kinojo Castle is known as the setting for the famous folk tale “Momotaro,” and many local place names are closely linked with the legend. The area also offers hiking trails with spectacular views overlooking mountains, plains, and more.
