A wooden hoe was excavated from the buried stream of 4C grid. It was belong to between the middle and the beginning of latter of the Final Jomon and was dated 790± 15〜25 cal BC by radiocarbon dating. Furthermore, a human bone was excavated from the abandonment deposit of the latter of the Final Jomon in 4D grid, and we were possible to sample the gelatin collagen from it for AMS dating. It was dated 3210-3080 cal BP. This archaeological datum was an interesting result. However, allowing for the imperfect remainder of collagen, there is necessity for careful treating the datum.
