A square mound 45m on a side and 9.4m high, built about 180m south-east of the rear circle of Hakayama Kofun. Its position has led to the view that it was related to Hakayama. The surrounding moat is preserved underground. Built in the late 5th century, it is administered by the Imperial Household Agency as a satellite of the Emperor Ojin mausoleum and is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
