A keyhole mound 110m long with a rear circle 9.9m high, built against the inner embankment on the east side of the front section of Konda Gobyoyama Kofun, the mausoleum of Emperor Ojin. It appears to have been built in two tiers. Its moat merges with the outer moat of the Ojin mausoleum, giving the appearance that the mound was incorporated into the larger monument; for this reason the two are thought to be closely related. Habikino City dates it to the late 4th century, while the Agency for Cultural Affairs dates it to the middle phase of the Middle Kofun period. The Imperial Household Agency administers it as a satellite tomb. In the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019, it forms a single constituent property with the Ojin mausoleum and Kondamaruyama Kofun.
