The tomb was built on the south slope of a ridge in the Shinaga valley, at the foot of Mount Nijō in the south-east of Osaka Prefecture. The shape of the mound is unknown. A fill of earth survives, 9.28 m long, 6.4 m wide and 0.9 m high.
The burial place is a horizontal-opening stone sarcophagus chamber (yokoguchi-shiki sekkaku), with its axis running north to south and its opening to the south. It is 2.19 m long and 1.2 m wide, with an interior length of 1.92 m. It is a sarcophagus-type chamber in the form of a house-shaped coffin, hollowed from a huge block of tuff. An entrance 0.77 m wide is cut in the south end face and fitted with a door stone. During levelling in the Taishō era, Sue-ware-type bricks bearing concentric-circle tapping marks were found around it, and it is inferred that bricks were piled around the chamber. Grave goods are not known.

The occupant is unknown, but tradition holds that the tomb belongs to Soga no Kurayamada no Ishikawamaro, who died in 649. The site was designated a prefectural historic site of Osaka on 31 March 1972. The Matsuizuka Kofun lies nearby; its stone chamber was moved to the Taishi Nagomi no Hiroba.

About this kind of monument
Japanese kofun tumuli
Kofun are the great burial mounds of ancient Japan, built mainly between the middle of the third century and the early seventh century CE. The period takes its name from them. The most distinctive form is the keyhole-shaped mound (zempō-kōen-fun), with one square end and one round end seen from above, but there are also plain round mounds, double-rectangle mounds and square mounds. Orientation is not fixed: in the Mozu group at Sakai, some round parts face north and others east.
The largest is Daisenryō kofun at Sakai in Osaka, the biggest kofun in Japan, thought to have been built over some twenty years in the middle of the fifth century. By common acceptance it is the tomb of Emperor Nintoku, and the Imperial Household Agency treats it as such, but this cannot be confirmed because the mound has not been excavated. It stands in the Mozu group, which once had more than a hundred tombs of which fewer than half remain; the group and the neighbouring Furuichi cluster were inscribed on the UNESCO World Heritage List in 2019. The mounds were built on a plateau overlooking Osaka Bay, near the ancient coastline.
Dating rests on mound shape, pottery and grave goods. Haniwa, which means "clay circle", are terracotta cylinders and figures of houses, animals and people that were arranged in rings and rows around and on top of the mounds. Smaller kofun are very numerous and sit in groups in every region of Japan.
When visiting, look for the moat that surrounds the larger mounds, for the stepped outline of terraces, and for reconstructed haniwa in museums and parks beside the tombs.
