Sanganji shell mound, Archaeological site in Shinchi, Japan.
The Sanganji shell mound contains multiple layers of shells, pottery fragments, and stone tools from ancient coastal settlements along the Pacific shoreline.
Excavations conducted in 1952 by the Japanese Archaeological Association revealed human remains and artifacts dating back approximately 4,000 years.
The site holds forty individual human remains that provide genetic information about the Jomon people who inhabited the Tohoku region.
The archaeological site stands near Shinchi Station on the JR East Joban Line, with a stone marker and information panel explaining its findings.
DNA analysis of teeth from the remains indicates specific haplogroups N9b and M7a2, showing connections to modern East Asian populations.
