Archaeological view
Kobe City’s conservation plan describes a two-tiered round mound 70m across and about 8.5m high; the 2006 designation supplement gives 67m. An estimated 320 haniwa stood on the summit and terrace, including finned cylindrical and morning-glory forms, house-shaped and quiver-shaped haniwa. Unlike Goshikizuka, it had no stone paving. It is dated approximately to the late 4th century, while its burial facility and occupant remain unknown.
