第２古墳群・101号墳
Tumulus 101, No. 2 Tumulus Group
辺15ｍの正方形に近い方墳
女狭穂塚古墳の陪塚である171号墳の2分の1の規格で築造され、
埴輪の製作技法や焼成、色調についても共通点が多く「ミニ 171 号墳」として捉えられる。
築造は５世紀前半頃の女狭穂塚築造に伴って築造され、女狭穂塚やその陪塚のために生産された埴輪の一部を分配されたとの想定が可能。
A square tomb with a side of 15m.
It was built to a standard of half that of the 171st mound, which is a jury mound of the Mesahozuka burial mound, and can be regarded as a "mini 171st mound," as there are many similarities in the production technique, firing, and color tone of the clay images.
It was constructed along with the construction of the Mesahozuka mound around the first half of the 5th century, and it is possible to assume that some of the haniwa produced for the Mesahozuka and its jury mound were distributed.
被葬者は男狭穂塚・女狭穂塚の被葬者と
密接な関係にあった人物という可能性が高まってきた
There is an increasing possibility that the buried person was closely related to the buried person of the Osaho and Mesaho mounds.
