Nagatsuka Kofun

Nagatsuka Kofun is a burial mound shaped like a keyhole, with a rectangular front section and a circular rear portion built at an elevated location. This double-shaped design represents a common burial style from the Kofun period that required significant labor and planning to construct.

Built in the 6th century, this mound demonstrates the construction skills of ancient Japanese society during the Kofun period. The engineering required to build such a large earthwork shows the organizational ability and resources available to those who commissioned it.

The tomb structure reflects the burial practices of elite members in Japanese society, incorporating specific architectural elements that signify social hierarchy.

This site is designated as a Prefectural Historic Site and is open to visitors who can walk around the mound. Comfortable footwear is recommended since the terrain is uneven and the ground may be soft in places.

Excavations at this site uncovered bronze mirrors, glass balls, and ancient pottery buried inside. These discoveries show what people valued and traded during the time when the mound was built.
