Archaeological view
Wakayama Prefecture takes it to be a round mound ~15m across and 5m high, with no recognized external features such as fukiishi or haniwa, built in the late 6th century. The chamber is of stacked crystalline schist: a horizontal stone chamber with a stone shelf at the back wall, of the type seen in the Iwase-Senzuka group and elsewhere.
