A round mound 35m across and 4.5m high, standing about 15m beyond the outer moat on the east side of Daisen Kofun—a position that suggests a connection with the great mound, though the Imperial Household Agency has not designated it a satellite tomb. Built in the first half of the 5th century, it is protected and managed by Sakai City as part of the National Historic Site Mozu Kofun Group. Excavation in 1912 found a wooden coffin laid directly in the mound, with two bronze mirrors, an iron sword, an iron blade and a large quantity of beads. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
Finds & research
Excavation in 1912 indicated a wooden coffin laid directly in the mound. From inside it came two bronze mirrors, an iron sword and an iron blade, together with a great quantity of beads: 7 magatama, 6 jujube-shaped beads, 71 tubular beads in 4 strings, 501 round glass beads in 5 strings, 1,531 small glass beads in 2 strings and 684 disc beads in 1 string. The jade magatama, 5cm long, is an unusually large and rare piece. Cylindrical haniwa are said to have stood around the foot of the mound, and its moat, built up against Daisen's outer moat, is preserved underground.
Two views on the occupant
Archaeological view
A round mound 35m across and 4.5m high, built in two tiers in the middle of the Middle Kofun period (first half of the 5th century), about 15m east of Daisen's outer moat. The proximity suggests a connection, but the IHA has not designated it a satellite. Excavation in 1912 indicated that the burial was a wooden coffin placed directly in the mound. The simple circular form is the most basic burial mound shape and was used by people of varied social ranks throughout the Kofun period. The name "Tsukamawari" (around the mound) indicates that it was used as a place name for an area where several mounds clustered.
