Mōri Terumoto
Mōri Terumoto, one of Toyotomi Hideyoshi's council of Five Elders, built Hiroshima castle between 1589 and 1599. It was located on the delta of the Otagawa river. There was no Hiroshima city or town at the time, and the area was called Gokamura, meaning "five villages". Beginning in 1591, Mōri Terumoto moved from Yoshida-Kōriyama Castle and governed nine provinces from this castle, including much of what is now Shimane, Yamaguchi, Tottori, Okayama and Hiroshima Prefectures.
