The site is located in the former town of Shibakawa, Shizuoka on a hill surrounded by lava flows from Mount Fuji. The site was found to contain the remnants of 14 pit dwellings, arranged around a horseshoe-shaped plaza. The dwellings have a hearth pit at the center, which was found to contain carbonized grains. The excavated remains included some 26,000 items, centering on shards of Jōmon period earthenware, hunting tools and stone implements.
