Hiroshima Castle

Mōri Terumoto, one of Toyotomi Hideyoshi’s council of Five Elders, built Hiroshima castle between 1589 and 1599.[1] 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.

When construction on the castle began, Gokamura was renamed Hiroshima, as a more impressive name was called for. “Hiro” was taken from Ōe no Hiromoto, an ancestor of the Mōri family, and “Shima” was taken from Fukushima Motonaga, who helped Mōri Terumoto choose the castle site. Some accounts state that the name “Hiroshima”, meaning “wide island”, comes from the existence of several large islands in the delta of the Otagawa, near the castle’s site.
