Kōchi Castle

About

Kōchi Castle (Kōchi-jō) is an Edo Period Japanese castle in the city of Kōchi, Kōchi Prefecture, Japan. It is located at Otakayama hill, at the center of Kōchi city, which in turn is located at the center of the Kōchi Plain, the most prosperous area of former Tosa Province on the island of Shikoku. From 1601 to 1871, it was the center of Tosa Domain, ruled by the tozama Yamauchi clan under the Tokugawa Shogunate. The castle site has been protected as a National Historic Site since 1959, with the area under protection expanded in 2014.
