Chihaya Castle (Chihaya-jō) is a Japanese mountain castle located in Chihaya, Chihayaakasaka Village, Minamikawachi District, Osaka Prefecture, and has been designated as a National Historic Site. The castle was built by the famous Southern and Northern Courts period general Kusunoki Masashige at the end of the Kamakura period. It served as one of his key strongholds against the shogunate and was also one of the renowned “Seven Castles of Kusunoki.” Due to its precipitous terrain, with cliffs on all sides, it was regarded as the most impregnable renkaku-style mountain castle (a type of fortress with multiple defensive enclosures) of its time.

Chihaya Castle was constructed on the western side of Mount Kongō, at the end of a mountain ridge. Since ancient times, this location was a strategic military point along the Chihaya Road, which connected Gojō in Yamato Province with Ōtsuka and Tondabayashi in Kawachi Province. The entire fortress made full use of the natural terrain for defense, spanning about 4 kilometers in circumference and built along the valley of the Chihaya River. To the north lay Kitadani Valley, to the southeast Myōken Valley, and to the east Furo Valley—each surrounded by deep, steep ravines—while only the rear side was connected to the summit of Mount Kongō, making it an excellent natural stronghold.

The highest point of Chihaya Castle reaches an elevation of about 673 meters, standing roughly 175 meters above the surrounding terrain, while Mount Kongō’s peak rises to 1,125 meters. Historically, the castle is most famous for the Siege of Chihaya, where Kusunoki Masashige, making use of cunning tactics and the advantageous geography, successfully repelled the far larger Hōjō (shogunate) forces. This remarkable victory, where the few defeated the many, is remembered as one of the classic battles in Japanese military history.
