A 225m-long keyhole mound, the fifth largest in the Furuichi area. Built on a central plateau with its rear circle at the eastern edge and its front section facing west, it appears especially large when viewed from the lowlands to the east and south. The rear circle rises 20.7m; the mound has three tiers and projections on both sides of the waist. A broad embankment about 32m wide encircles the moat. The Imperial Household Agency administers the mound as a satellite of the Ojin mausoleum, while part of its embankment is included in the National Historic Site Furuichi Kofun Group. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
Records mention two burial facilities set north–south in the rear circle, the northern one said to contain a large chest-shaped sarcophagus, but the mound is unexcavated under IHA management. Cylindrical haniwa have been recovered along with figural pieces shaped as houses and quivers; a haniwa of a man holding a shield is among the earliest human figures of its kind. A moat rings the mound, with a broad embankment about 32m wide beyond it, and a ditch bounding that embankment has been detected on parts of the east and north sides.
