Overview
Satellite tomb "Otsu" of Daisen Kofun: a round mound 62m across and 9.7m high—the largest round mound in the Mozu area. Like Chayama Kofun (56m), it is built into the middle embankment of Daisen Kofun where that bank widens toward the outer moat. Only these two mounds in the entire Mozu-Furuichi complex stand on a bank between moats, a mark of how closely both are tied to Daisen. The mound appears to have been built in two tiers. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.

Satellite tomb "Otsu" of Daisen Kofun: a round mound 62m across and 9.7m high, built in two tiers, and the largest round mound in the Mozu area. Dated to the middle of the Middle Kofun period (first half of the 5th century). Together with Chayama (56m) it forms part of Daisen's middle embankment — one of only two mounds in the Mozu-Furuichi complex raised on a bank between moats.
