Kochi Castle,renowned as a famous castle with over a 400-year history,is one of Kochi's representative sightseeing spots. It was constructed by Yamauchi Katsutoyo -who entered the province (then called Tosa) in 1601 as the first feudal ruler of the Tosa domain- and completed in 1611. (It was later destroyed by fire and rebuilt in 1753)
15 of the castle's buildings, including the tenshu(keep), are designated as Important Japanese Cultural Assets.
In particular,the honmaru (innermost ring of defence), including the tenshu, palace, and other buildings, have remained intact right up to the present day, without suffering zoos or destruction by fire or war, and in the same state as they have since the Edo period. Kochi castle is the only castle in Japan to retain all of these buildings in their original state. The castle was originally named Kochiyama Castle, which are said to be the origin of the modern day name of Kochi.
