Satellite tomb "Chi" (No. 8) of Daisen Kofun: a round mound 34m across and 5.4m high as it stands today (Sakai City Museum reports that a 1989 excavation showed the original moated mound to have been 48m across), built in the first half of the 5th century about 30m outside the outer moat on the north-east side of Daisen Kofun—a position that suggests a connection with the great mound. It was raised in two tiers, and its moat is preserved underground. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
Finds & research
Details of the burial facility and grave goods are unknown. Cylindrical haniwa have been recovered from the moat, and the surrounding moat is preserved underground.
