Shionjiyama Kofun, Ancient burial mound in Yao, Japan.
The Shionjiyama Kofun features a distinctive keyhole shape with one square end and one circular end, measuring 160 meters in total length.
Built during the 5th century CE, this burial site contains three chambers where archaeologists discovered bronze mirrors, weapons, and valuable artifacts.
The mound originally displayed over 3000 haniwa clay figures, including ceremonial sculptures that represented the spiritual beliefs of ancient Japanese society.
The archaeological park maintains the tumulus grounds and offers educational exhibits at the nearby Shionjiyama Kofun Learning Center.
Located on a natural slope at 30 meters elevation, the mound required split embankments on its north and south sides to accommodate the terrain.
