Ataka Shell Mound

Japanese: 阿高貝塚 - あたかかいづか

A Jomon period shell mound located in Ataka, Jonan Town, Shimomashiki County, Kumamoto Prefecture. One of a group of shell mounds in the southern Kumamoto Plain, it is located at the edge of a plateau extending from Mt. Kihara and faces the Hamado River, a tributary of the Midorikawa River. It was discovered and investigated in 1916, and many human bones were found. In 1977, an investigation was carried out to confirm the shell layer and the extent of the ruins, and part of what appears to be the site of a square pit dwelling with rounded corners was discovered. The shell mound is mainly composed of oysters, followed by Yamato corbicula. It is an inland bay shell mound with other prominent species such as agemaki clams and hard clams, in contrast to the Goryo shell mound located about 300m to the east, which is mainly composed of Yamato corbicula (over 90%).

熊本県下益城郡城南町阿高にある縄文時代の貝塚。熊本平野南部の貝塚群の一つで，木原山よりのびた台地端にあり，緑川支流浜戸川に面する。1916年に発見調査され，多数の人骨が検出された。77年に，貝層と遺跡の範囲確認の調査が行われ，隅丸方形の竪穴住居址らしい遺構の一部を検出した。貝塚はマガキを主体とし，ヤマトシジミがそれに次ぐ。ほかにアゲマキ，ハマグリが目立つ内湾性貝塚で，東方約300mにある御領貝塚の主体がヤマトシジミ(90％以上)であるのと対照的である。
