Otsurumaki-kofun

The Otsurumaki-kofun burial mound extends 123 meters in length and features a distinct keyhole shape with square and circular sections surrounded by double moats.

Built between the late 4th and early 5th centuries, this tomb represents the architectural methods and burial practices of the Kofun period in Japanese history.

The presence of haniwa figures and fukiishi stones within the structure demonstrates the advanced engineering and ceremonial practices of ancient Japanese society.

Archaeological excavations during the Meiji period uncovered clay fragments within the mound, though the main burial chamber remains unexplored.
