A large egg-shaped round mound in Daisen Park, measuring 61m by 56m and 3.7m high. It is the second-largest round mound in the Mozu group after Daianjiyama. The mound top had already been levelled before park construction, but the moat fill is likely to survive relatively well. Excavation identified a construction method in which blocks of dug soil were stacked upside down.

Displaced cylindrical and figural haniwa, Sue ware, and a miniature iron hoe have been recovered. The burial facility and grave goods are unknown.
