Kochi Castle is one of only twelve castles in Japan with an original wooden tenshu (keep) that escaped destruction by fire or war.
The castle grounds were built between 1601 and 1611 under the direction of Yamauchi Kazutoyo.
The park contains the Yamauchi Shrine, located just outside the castle's main Ote-mon gate.
The steep stone walls were designed specifically to deter enemy climbers during the feudal era.
The castle layout follows the 'hirayamajiro' style, meaning it is a flatland-mountain castle.
Kochi Park serves as the primary grounds for Kochi Castle, one of the few Japanese castles to retain its original wooden keep after the Edo period. The park spans the former site of the Ote-mon gate and the extensive bailey area of the Yamauchi clan's administrative center. It contains the preserved Honmaru, or main citadel, which survived both the 1727 fire and subsequent World War II bombings. The site features the statues of Yamauchi Kazutoyo and his wife, Chiyo, who are central figures in local Tosa history. Visitors can walk through stone walls and steep stone staircases that defined the defense strategy of the Tosa Domain. The park is surrounded by remnants of the original moat system and secondary defensive earthen mounds. It functions as a public garden integrating historical military architecture with landscaped gardens. The site is a primary location for local cherry blossom festivals in the spring.
