（88）福岡県糸島市の築山（つきやま）古墳（伊都国の中心部に位置）
Tsukiyama Tumulus in Itoshima City, Fukuoka Prefecture (Located in the center of Ito Province)
今回は糸島市を家族で巡った時にちらっと寄っただけなので、写真も3枚しかないのですが、この古墳は、中国の魏志倭人伝に記された「伊都国」の中心部に築かれているとのことなのでこの機会にご紹介まで！。
This time, I only stopped by when I was touring around Itoshima City with my family, so I only have three photos.
This burial mound was built in the center of "Itokoku" as described in the Chinese Book of Records of the Wei Dynasty, and I would like to take this opportunity to introduce it to you!
墳形は前方後円墳で、帆立貝式のため前方部が短い
全長約60ｍ、後円部直径49ｍ・高さ約8ｍ、前方部長さ約15ｍ・幅約25ｍ
The shape of the tomb is a forward and backward circle tomb with a short forward section due to the scalloped shell style.
It is about 60 meters long, 49 meters in diameter at the back of the circle, 8 meters high, 15 meters at the front, and 25 meters wide.
斜面には葺石、周囲は盾形の周壕がめぐり、それを含めた全長は約105ｍに達する。
周壕からつぼ型埴輪・円筒埴輪が出土
埋葬施設は未調査
The slope has thatched stones, and a shield-shaped shelter surrounds it, and the total length including the shelter reaches about 105m.
Vase-shaped Haniwa (clay figurine) and cylindrical Haniwa (clay figurine) were excavated from the shelter.
Burial facilities have not been investigated.
築造はAC360-390年ごろ（4世紀末）と推定。
It is estimated to have been built around 360-390 AC (the end of the 4th century).
被葬者は伊都国の王に代わってこの地を治めた、
やまと政権と深いつながりのあった豪族と考えられている。
The buried person is thought to be a powerful family who ruled the area on behalf of the king of Itokuni and had close ties with the Yamato regime.
