Most of the tombs are accompanied by a covering stone, and only Tomb 5 does not have a covering stone. Tombs 2 and 3 have coral gravel burial beds. Tombs 3 through 7 each contain one body, but Tombs 1 and 2 are divided into upper and lower sections, indicating that secondary burials were performed.

Four of the remains showed evidence of tooth ablation.The upper layer of the graves included earthenware vessels and shell jewelry as grave goods, and a Yayoi pottery jar and a polished stone axe were found adjacent to the outside of the stone cist. The shell artifacts included shell bracelets made from Turbo marmoratus, Strombus luhuanus, Patella vulgata, and Trochus niloticus, as well as perforated shell artifacts made from Conus, Cypraea, and Patella vulgata.
