Oguni

The Oguni were a warrior family of Echigo Province descended from Minamoto no Yoriyuki. In 1336 Oguni Masamitsu, a Southern Court supporter based at Tenjinyama Castle, lost Shimazaki Castle to Ashikaga forces.

In the sixteenth century Oguni Yorihisa served Uesugi Kenshin in campaigns including Kawanakajima. After Kenshin's death the family split between rival heirs. The victor Kagekatsu imposed his retainer's brother as family head; taking the name Ōkuni Saneyori, he was later expelled, but his successors served the Yonezawa domain.
