Ōuchi Hiroyo

Ōuchi Hiroyo (c. 1326–1380) was the ninth head of the Ōuchi clan and a Nanbokuchō shugo daimyō, son of Ōuchi Hiroyuki. In 1351 he submitted to the Southern Court and was named Suō shugo; after his father's death in 1352 he fought the Washizu and brought their faction under his authority, taking Nagato as shugo in 1358.

In 1360 he moved the clan seat to Yamaguchi, laying out a town modeled on Kyoto that became the base of later Ōuchi culture. He submitted to the Muromachi bakufu in 1363, added Iwami in 1366, and died in 1380.
