was a Japanese samurai and commander of the Sengoku period. Motozumi was one of the most important retainers of the Mōri clan.[1] [2] He was also the castle lord in command of Sakurao Castle.[1]
Saka Hirohide, who was related to Motosumi's father Katsura Hirozumi, rebelled against Mōri Motonari. Hirohide was dissatisfied with Motonari's succession to the family headship, but the rebellion ended in failure . Later, Hirozumi took responsibility for the conflict and committed seppuku.[3] [4] In the Battle of Miyajima, Motozumi succeeded as a decoy and lured Sue Harukata's army toward Itsukushima and so contributed to the victory of the Mōri clan.[5]
