Multiple excavations by Sakurai City Board of Education and the Kashihara Archaeological Research Institute (national historic site designated 1972). Burial facility: the uniquely hybrid "mokkaku vertical-shaft stone chamber" (~6.5m long) combining a wooden outer coffin (Yayoi tradition) with a vertical-shaft stone chamber (Kofun feature). Key finds: bronze mirrors (three inner-flower-pattern mirrors, one triangular-rimmed deity-beast mirror, etc.); iron swords; ~60 iron arrowheads; ~60 bronze arrowheads; stone artifacts (stone arrowheads, small knives); Furuichi-style pottery; stone paving; and traces of wooden shield-shaped structures. The mixture of Yayoi and Kofun-type grave goods is the most archaeologically significant aspect. Some finds displayed at the Sakurai City Buried Cultural Property Center.
