| Outline of Final Research Achievements |
The purpose of this study is to find traces of seeds and insects in the paste of earthenware using X-ray equipment and to verify what Jomon people's feelings about cultivated plants and when continental grains such as rice were accepted by Jomon people. As a result, we found an earthenware mixed with a large number of weevils at a Jomon site of Hokkaido and estimated that chestnuts were cultivated along with legumes in eastern Japan, and were spread to Hokkaido along with the pests by Jomon people. Additionally, a difference of main nuts consumed by Jomon people between eastern and western Japan was revealed. With the settlement, soybeans, chestnuts, etc. were begun to be cultivated and stored, and food pests occurred there, and they spread throughout Japan along with the transportation of foods. It was clarified that the plant culture, which was thought to have existed after the Yayoi period, and the sensibility to pray for its fertility already existed in the Jomon period.

| Academic Significance and Societal Importance of the Research Achievements |
縄文時代はこれまで狩猟・採集の時代と考えられてきた。しかし、2007年に縄文土器の圧痕としてダイズが発見されて以来、縄文人が有用植物を栽培していたことが明らかになった。この土器圧痕はまさに縄文人が作り出した人為化石である。本研究はX線機器を用いて土器中の圧痕をすべて検出するという研究手法の精確性や高効果性から、多量のタネやムシを入れた土器の発見につながった。これまで、主に年代指標として使われていた土器を、新たな生活史・思想史復元の資料源とみなし、縄文人たちの生活や栽培植物に対する想いを掘りだすこの研究は、私たちがステレオタイプ的に考えている歴史観を覆す可能性を秘めている。
