The ruins of the Sagara Kokubunji Temple feature reconstructed tower remains, lecture hall remains, and main hall remains using 14 foundation stones, giving visitors an idea of what it was like during that time. The stone chamber and circular mound, built during the mid-Kofun period, indicate that there was communication with the southern regions. Not only can visitors see the historical buildings, but they can also imagine the politics and rulers of the time. Please come and visit at least once.
