Akasaka Tennōzan Kofun

Akasaka Tennōzan Kofun is a square-shaped burial mound from the late sixth century featuring three terraced levels and a stone chamber inside. The chamber holds a house-shaped stone coffin made from pale volcanic stone with a recessed top opening.

This burial mound was constructed in the late Kofun period, when such large graves were built for prominent individuals in Japanese society. The design and stone chamber reflect the advanced building practices of that era.

This burial site reflects how ancient Japanese communities honored their deceased and organized elaborate funeral practices. The scale and construction methods show the resources and skills that existed in this region during that period.

The site is easily accessible for visitors interested in exploring ancient Japanese burial practices and archaeology. Visitors can observe the exterior structure and terrain while learning about construction methods from this historical period.

The stone coffin features unusual projections on its sides designed for securing ropes, and a square opening at the top that served specific ritual or practical purposes. These precise carved details are rarely seen and demonstrate the craftsmanship involved.
