Excavations that began in 1992 found large settlements from the early to middle Jomon period (approximately 3,900-2,200 BC, approximately 5,900-4,200 years ago). Many ruins of pit dwellings, pillar-supported buildings, mounds, and burial pits were unearthed, along with numerous earthenware, stoneware, precious wooden objects, and objects made from bone and horn. 

In 1995, the maintenance of the ruins was begun, and they were opened to the public. In 2002, the Jomon Jiyukan was opened to hold and display excavated items. In 1997, the site was designated as a National Historical Site, and in 2003, 1958 artifacts excavated there were designated as important cultural properties.
