The archaeological site of Mitsuoka Tsunenoen (Mizuo Tsuji no Ichiki) was founded in 1996 as a result of housing construction, and the village ruins from the middle Yayoi period to the early period of the Kofun period were confirmed. The Yasushi Azoneite made beast shaped gems and Kinki Traditional V style styles of southern bodies are important materials. In addition, as an attached section, collections collected from the first half of the 5th century to the sixth century Egyptian ware of the Mukuoka long-grab ruins (Mizuka Kana) are also posted.
