A satellite tomb of Daisen Kofun, designated "Ho tobichi" (detached parcel). It is thought to have been a scallop-shaped mound with its front section facing south. What survives is 33m long and 4m high (the Sakai City Museum gives 33m and 4m as the original full length and height), apparently built in two tiers, and dated to the first half of the 5th century. It stands about 100m beyond the outer moat on the west side of Daisen Kofun's rear circle, and from its position it is thought to have been associated with the great mound. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
