The Tosa Domain was based at Kōchi Castle in Tosa Province, in the modern city of Kōchi, located on the island of Shikoku. The Tosa Domain was ruled for its existence by the "tozama daimyō" of the Yamauchi and its territory covered Tosa Province. 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. The Tosa Domain was renamed the during the early Meiji period until it was dissolved in the abolition of the han system in 1871 and became Kōchi Prefecture.
