The tumulus stands on the eastern edge of the Abe Hills, on the left bank of the Terakawa River in the southern part of the Nara Basin. Its shape is rectangular, with the northwest and southeast sides slightly longer, measuring approximately 27 meters on the long side and 21 meters on the short side. The top of the mound is flat and shaped like a truncated cone. Fukiishi have been found on the outside of the mound, but no haniwa clay figures. The mound is surrounded by a flat area, and there is no trace of a moat.
The burial chamber is a horizontal-entry large stone chamber made of megaliths, with an opening to the southeast. The gaps between the stone walls were plastered, and traces of the plaster remain. The burial chamber has a total length of 13.16 meters, with the main chamber measuring 4.44 by 2.71 meters and 2.0 meters in height.

No archaeological excavation has been conducted to date. Inside the chamber is a hollowed-out house-shaped stone sarcophagus of stratified hyaloclastite, which had been brought to the site from the Kakogawa River basin in Hyogo Prefecture. The cover stone has a pair of rope-hanging protrusions on the front and back and two pairs on the left and right, and the inside is shallowly carved. As the sarcophagus is larger than the entry passageway, it must have been placed in the burial chamber during the construction of the tumulus.
The burial chamber has been open since antiquity, and the existence of any grave goods is unknown.

Tradition and region
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.
