Tosa Domain (Japan)

The Tosa Domain (土佐藩, Tosa-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, controlling all of Tosa Province in what is now Kōchi Prefecture on the island of Shikoku. It was centered around Kōchi Castle, and was ruled throughout its history by the tozama daimyō Yamauchi clan. Many people from the domain played important roles in events of the late Edo period including Nakahama Manjirō, Sakamoto Ryōma, Yui Mitsue, Gotō Shōjirō, Itagaki Taisuke, Nakae Chōmin, and Takechi Hanpeita. Tosa Domain was renamed Kōchi Domain (高知藩, Kōchi-han) during the early Meiji period until it was dissolved in the abolition of the han system in 1871 and became Kōchi Prefecture.
