01 / Burial mound
On the rear wall of a chamber of stacked pumice,a slab suggesting a five-ring pagoda is set.

This prefecturally designated historic site is a round mound 30 m across and about 4 m high. In its chamber, human-head-sized natural stones are laid at the bottom and dressed pumice is stacked above them as the side walls. The prefecture records that this type of tomb, thought to date from the late Kofun period, has no precedent in the Kanto region.
