A mirror dated Keisho 3 (239)came from the central burial facility.

Three burial facilities lined up east to west in the rear circular part were found in excavations in 1950-51. A bronze mirror with deities and animals (gamontai shinjukyo) from the central clay chamber bears the inscription Keisho 3 (239). The finds are designated together as Important Cultural Properties and kept by the Tokyo National Museum, and the kofun became a National Historic Site in 2008.
