Kinsei site is a village and stone monument site from the Late to Final Jomon Periods (c. 2,500?400BC). A large number of artifacts, such as pottery vessels, stone tools, clay figurines (dogu), ornaments made of precious stones, clay ear spools, and burnt jaws of wild boar, are representative of the complexity of the Late to Final Jomon culture. This site was designated National Historic Site in 1983 and was developed into a site park. Reconstructed houses currently stand above their original positions near the stone relics. Artifacts excavated from this site are stored and exhibited at the Hokuto City Archaeological Museum.
