Dainichi Kofun

Dainichi Kofun is an ancient burial mound with an elongated oval shape situated on a plateau at the base of Mount Nishime. The structure measures approximately 40 by 20 meters and extends toward the southwest, containing an impressive horizontal stone chamber inside.

The burial mound was constructed in the late 7th century, a period when such monuments were gradually falling out of use in Japan. The stone chamber reveals the technical skills of the era and demonstrates connections through trade routes reaching the distant Kinai region.

The mound's prominent position on the plateau reflects how burial structures once marked important centers of power and reverence in the region. The name Dainichi connects the site to spiritual beliefs, showing how the place was tied to religious meaning in everyday life.

The mound sits on elevated ground offering good views of the surroundings, but this also means being prepared for sloped terrain during your visit. Taking time to observe the setting and vantage point helps you understand why this was an important burial site in its region.

Local tradition links this burial mound to Prince Imseong of Baekje, who is believed to be an ancestor of the powerful Ouchi clan. This connection to a Korean princely figure reveals the close relationships between Japan and the mainland during that era.
