The kofun lies in the southeastern part of the Nara Basin, at the western foot of Mount Miwa. The area contains the Yamato Tomb Group, including the Hashihaka Kofun, dating from the early Kofun period (the 3rd to the latter half of the 4th century). This kofun, however, is from the middle of the Kofun period, and no other major tombs from around the time of its construction are in the immediate vicinity.

The tumulus is a scallop-shaped kofun (帆立型古墳) orientated to the north. It has a length of 67 meters, with a posterior circular portion 56 meters in diameter and eight meters tall. The anterior portion has a maximum width of 29 meters and is two meters tall. A reservoir pond on the west side of the tumulus is thought to be the surviving remains of a moat. The posterior mound is constructed in five tiers, with fukiishi and cylindrical and house-shaped haniwa on the surface.

The tumulus was excavated in 1978. In 2011 a haniwa from the late 4th century depicting a human head on a shield was found in the moat; it is the oldest anthropomorphic haniwa yet discovered. The burial facility is unclear, and details about the grave goods are also 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.
