Ōhakayama Kofun

Ōhakayama Kofun is an ancient burial mound shaped like a keyhole, with a rectangular section at the front and a circular section at the back. The entire structure measures roughly 46 meters long and rises about 6 meters high at its deepest point.

Built in the middle of the 6th century, this mound is part of the Arioka Kofun Group. It contains some of the oldest gilt-bronze crowns ever discovered in Japan.

The site serves as a place where visitors come to show respect for those buried here in ancient times. The way the burial chamber is arranged tells us about beliefs and customs that shaped funeral practices in the community.

The site is located in a rural area and is best reached on foot or by bicycle. There is straightforward access to the mound itself, though visitors should be prepared for varying ground conditions depending on the weather.

Inside the chamber sits a rare stone house structure, a type of architectural element common in the Kyushu region but seldom seen in Shikoku burial mounds. This distinctive feature sets the site apart from other mounds nearby.
