But since there were Kibi-style ceremonial vessel stands, same as Hashihaka-kofun Tumulus, were lined in the back circular part (by Terasawa, 2000), and also because of the shapes of Haniwa (unglazed terra-cotta cylinders and hollow sculptures arranged on and around the mounded tombs) and the mound, there is another idea that it was a tumulus for okimi (great king) in the period after Hashihaka-kofun Tumulus (by Shiraishi, 1999).
しかし箸墓古墳と同様の吉備様式の特殊器台が後円部に並び（寺沢2000）、埴輪や墳丘の形態等からも箸墓古墳に続く時期の大王墓という見方がある（白石1999）。
