別所茶臼山古墳

The Bessho Chausu-yama Kofun is a burial mound with a distinctive keyhole shape formed by linking a circular section to a trapezoidal platform. This configuration created a striking landmark visible from great distances across the landscape.

This burial mound was built between the 3rd and 7th centuries when local rulers commissioned monumental tombs to display their authority. The size and design of these structures reflect the growing complexity of political organization during that era.

The mound demonstrates how rulers of that era used burials to display their authority and influence to the surrounding community. The earthwork itself was meant to be seen and remembered by people passing through the landscape.

The site is located in Gunma Prefecture and is accessible to visitors who can explore around the exterior mounds. Visiting during daylight hours provides the best view to appreciate the distinctive keyhole shape.

Excavations uncovered precious items like bronze mirrors, weapons, and jade ornaments buried with the deceased, revealing the wealth and status of the entombed ruler. These discoveries provide rare insights into the craftsmanship and material choices of that period.
