In particular, both 103m long Hazamiyama tumulus and the 154m long Nonaka Miyayama tumulus exist entirely within the area of this remains, and it is considered that they had some relations to the formation of communities in ancient times and later.
特に、墳丘長103mのはざみ山古墳と墳丘長154mの野中宮山古墳は、この遺跡の範囲内にすっぽり収まり、古代以降の集落形成に何らかの関係をもったと考えられる。
