Kanasaki Kofun Cluster is a group of burial mounds in Kanazaki, Minano, Chichibu District, Saitama Prefecture, Japan. The cluster stands on a river terrace along the left bank of the Arakawa, extending southwest from the foot of Hōtodorisan.
The cluster once contained more than 8 round burial mounds. Today, the surviving mounds and burial chambers are Ohsakaizuka Kofun No. 1 through No. 3 and Tenjinzuka (Himeamizuka) Kofun, making 4 round mounds in total.
Five swords are said to have been excavated from Tenjinzuka by a local youth group during the Taishō period. One of the five is decorated with silver inlay. The swords were designated a tangible cultural property of Minano on 1993 (Heisei 5) May 28 and are kept by the Minano Town Board of Education.
The cluster was designated a Saitama Prefecture historic site on 1976 (Shōwa 51) March 30. Its burial mounds are dated by typological estimate to 250 CE to 650 CE. Kofun are the great burial mounds of ancient Japan, built mainly between the middle of the third century and the early seventh century CE; besides keyhole-shaped mounds, they include plain round, double-rectangle and square forms.

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.
