While the special vessel stands and jars, which are presumed to have been brought from Okayama City and its environs, are only seen in the rounded rear, the jar-shaped Haji pottery with a dual-rimmed mouth and holes on the bottom have been gathered from the square front.
また、岡山市付近から運ばれたと推測できる特殊器台・特殊壺が後円部上でのみ認められるのに対して底部に孔を開けた二重口縁の壺形土師器は前方部上で採集されている。
