Kochi Castle
The only castle in Japan where both the original keep and the original lord's residence survive together.
Updated 20 October 2026
Kochi is one of the twelve original keeps, but its distinction is different: it is the only castle in Japan where the keep and the honmaru palace - the lord's residence at the top of the hill - both survive from the same period. Everywhere else the residences were demolished, burned or rebuilt, so the sequence of rooms leading to the keep exists nowhere but here. Both date from a reconstruction completed in 1749 after a fire; you walk from the palace's tatami rooms directly into the keep and up its steep floors to an open balcony at the top with a view over the city and the Kagami river. Fifteen structures on the site are important cultural properties. Below the walls a street market has been held every Sunday since 1690, running about a kilometre along the road from the castle gate.
History
After his defeat by Toyotomi Hideyoshi in 1585, Chōsokabe Motochika chose Otakayama hill for a new castle, and after 1600 the Tokugawa shogunate gave Tosa to Yamauchi Kazutoyo. Much of the castle burned in 1727 and was rebuilt in the original style between 1729 and 1753, and it was spared both in the Boshin War and by the Meiji orders to pull down feudal castles (Wikipedia, Kōchi Castle).
The main sights
- Keep and residence together - the only surviving pairing of its kind in Japan.
- A 1749 rebuilding - both structures from the same post-fire reconstruction.
- An open top balcony - a walk-out gallery over the city and the river.
- The Sunday market - a kilometre of stalls from the castle gate since 1690.
When to go
Sunday, for the market as well as the castle. Two to three hours.
Practical notes
The keep stairs are very steep. The walk up from the gate is a climb in itself. Interiors are bare and explanation is largely in Japanese. Summer in Kochi is hot and humid.
Nearby
Hirome Market is beside the castle; Katsurahama is south on the coast.
