Choshu domain, located at the western tip of the main island of Honshu, with a castle town in Hagi, a small town famous today for preservation of its feudal ambiance, was ruled over by the Mori family during the Edo period. Choshu was one of the four domains which overthrew the Tokugawa shogunate and restored the Emperor to authority. Men from Choshu and Satsuma dominated government in the late 19th and early 20th Centuries. During the Edo period, Choshu was prevented from a national role because the domain fought against the Tokugawa at the battle of Sekigahara in 1600.
