応神天皇
Because as Emperor Ōjin he was an ancestor of the Minamoto clan, Hachiman became the of the Minamoto samurai clan of Kawachi (Osaka). After Minamoto no Yoritomo became "shōgun" and established the Kamakura shogunate, Hachiman's popularity grew and he became by extension the protector of the warrior class the "shōgun" had brought to power. For this reason, the "shintai" of a Hachiman shrine is usually a stirrup or a bow.
