Emperor Ojin became the crown prince at the age of four. He was crowned (in 270) at the age of 70 and reigned for 40 years until his death in 310. He supposedly lived in two palaces both of which are in present day Osaka. Ōjin is traditionally identified as the father of Emperor Nintoku, who acceded after Ōjin's death. Ōjin has been deified as Hachiman Daimyōjin, regarded as the guardian of warriors. The Hata Clan considered him their guardian Kami. The actual site of Ōjin's grave is not known, but he is traditionally venerated at a memorial Shinto shrine (misasagi) at Osaka. The Imperial Household Agency designates this location as Ōjin's mausoleum. It is formally named Eega no Mofushi no oka no misasagi.
