모리 데루모토
In 1600, Mōri Terumoto nominally led the West Army in the Battle of Sekigahara. The West Army lost the battle and the Mōri clan lost three eastern provinces and moved their capital from Hiroshima to present-day Hagi, Yamaguchi. The newer fief, Mōri han, consisted of two provinces: Nagato Province and Suō Province. Derived from the former, Mōri han was referred to often as Chōshū han.
