Kôchi castle was the seat of the Yamauchi clan, lords of Tosa han.

It is located in the city of Kôchi, today capital of Kôchi prefecture, on the south shore of Shikoku.

The castle began its life as a basic yamashiro in the mid-1300s. Chôsokabe Motochika raised a larger, permanent structure in place of this in 1588 but soon moved his headquarters further south to Urado castle. After the Chôsokabe found themselves on the losing side of the battle of Sekigahara in 1600, Tosa province was given in fief to Yamauchi Kazutoyo, who initially used Urado as his base, but saw a need for a larger castle town to center his domain, and so kept many of his retainers in Osaka and Edo while they awaited the construction of the new castle, and the larger city of Kôchi, about five miles north of Urado.

Kazutoyo began to rebuild the castle at Kôchi in 1602, enlisting both samurai and commoner/peasant labor, and removing some parts of Urado castle to construct the new castle, based on a plan by his chief building magistrate, Dodo Echizen.[1] The tenshu was completed in 1603, and construction of the complex as a whole was completed in 1611. The castle was heavily damaged by an earthquake in 1707. Just as repairs were being completed, the tenshu and honmaru complex were destroyed by fire in 1712. Another fire in 1727 added further damage to the castle grounds. A major reconstruction project was begun in 1729, with the tenshu and a turret gate being completed in 1747. Construction finished up in 1753. While the castle was never tested in warfare, an invasion of sorts brought down the castle: termites damaged the tenshu to the verge of collapse in the mid-20th century and it had to be disassembled beginning in 1949. The damaged parts were replaced and reconstruction was completed in 1955.

The castle has a typical hirayamajiro layout - the grounds consist of a honmaru located on Otakasakayama (a hill about 42 meters high), a ninomaru to the north on a lower level, and a sannomaru to the east on a slightly lower level. A nishinomaru along with residences was built at the foot of the hill. The castle featured many stone walls with zig-zagging bends and stone-dropping holes at the corners. It also had fences with spears located between the walls, pointing outwards and providing an effective deterrent to any enemy advance. The tenshu has four exterior and five interior levels and is unique among Japanese castles for having a two-level ishigaki stone base. The Kaitokukan ("Hall Of Desire For Virtue") is located next to the tenshu and served as the daimyô residence. It is one of the rare surviving shoin style Edo period daimyô residences. Along with the tenshu and Kaitokukan, the East and West tamon yagura, Kokutetsu-mon, Kurogane-mon, and Roka-mon, are other original structures on the site classified as Important Cultural Properties.
