Hida Bokaru was the third son of Crab Clan Champion Hida Banuken, and defender of the eastern portion of the great southern wall. In 715 he was defending the Tidal Landbridge from the attacking Oni no Kinjiro and was seriously injured. He only lived because of the timely assistance from the Daidoji Daimyo Daidoji Masashigi. Masashigi and Kinjiro were drowned in the high tide, and a shrine was erected in Masashigi's memory. This also created the strong respect the Hida family have for the Daidoji.
