A square mound adjoining the moat on the south-east side of the rear circle of Itasuke Kofun. It is reconstructed as 28m long; its altered upper part now survives to a height of 3m, and it was probably built in two tiers. From its position it is thought to be related to Itasuke Kofun. Built in the first half of the 5th century, it is part of the National Historic Site Mozu Kofun Group. Cylindrical haniwa stood at intervals of about 2m on a pebble-paved terrace. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.
Finds & research
Cylindrical haniwa stood on a pebble-paved terrace at wide intervals of about 2m. Excavation found no trace of a moat, so the mound most likely had no boundary feature. The burial facility and grave goods are uninvestigated.
Two views on the occupant
Archaeological view
A square mound reconstructed at 28m per side, now 3m high and probably built in two tiers. It stands against the moat on the south-east of Itasuke Kofun's rear circle and is read as connected with it. Dated to the middle of the Middle Kofun period (first half of the 5th century). Occupant unknown. The proliferation of square-form satellite and accessory mounds in the Middle Kofun period is a feature common to both the Mozu and Furuichi groups, where clusters of square mounds are found around the large keyhole mausolea.
