Ōhakayama Kofun, Ancient burial mound in Zentsuji, Japan.
The Ohakayama Kofun extends 46 meters in length, featuring a keyhole design with a rectangular front section and circular rear portion reaching six meters high.
Built during the mid-6th century, this burial mound belongs to the Arioka Kofun Group and contains Japan's earliest discovered gilt-bronze crowns within its stone chamber.
The burial chamber's southeast orientation and architectural elements demonstrate specific funeral customs and social hierarchy practices of ancient Japanese society.
Visitors can access the stone chambers and receive guided tours by cultural preservation specialists during the annual Kofun Day celebration on April 29.
The site contains a rare stone house structure within its chamber, a feature commonly found in Kyushu but seldom present in Shikoku region tumuli.
