Ōyasuba Kofun, Ancient burial mound complex in Kōriyama, Japan
The Ōyasuba Kofun features five burial mounds, with the largest measuring 83 meters in length and following a two conjoined rectangles design pattern.
Excavation studies between 1996 and 1998 revealed numerous artifacts including swords, spears, and jewelry dating from the second half of the 4th century.
The discovery of red-colored Sue ware pottery within the burial chambers indicates specific ceremonial practices of the ancient Japanese elite society.
The archaeological site, located in Ōyasuba Historic Park, can be reached through a ten-minute walk from the Kanaya bus stop in Kōriyama.
The main tumulus contains a clay-floored burial chamber stretching 10 meters in length, housing a preserved tree-coffin measuring 9.2 meters.
