Yamana Yoshinori

Yamana Yoshinori (died 1219) was a Kamakura-period samurai lord and founder of the Yamana clan. A concubine's son of Nitta Yoshishige of the Seiwa Genji, he held Yamana township in Kōzuke Province, from which he took his name, and around 1175 founded the Yamana Hachiman shrine.

When Minamoto no Yoritomo rose in 1180 Yoshinori joined him, unlike his hesitant father. He fought in the Genpei War, served under Minamoto no Yoshitsune in 1184, was made governor of Izu Province in 1185, and joined the Ōshū campaign of 1189.
