What Is Kochi Castle? A Historic Castle with an Original Keep and Honmaru Palace
Kochi Castle is a historic Japanese castle located in Kochi City, Kochi Prefecture.
It is said that construction began in 1601 (Keichō 6) by Yamauchi Kazutoyo, the first lord of the Tosa Domain, and that it was completed over many years.
