Outline of Final Research Achievements

In the course of the project, the corona disaster forced a two-and-a-half-year self-imposed suspension of activities. Therefore, the project has not been carried out as originally planned. However, since the fall of 2021, when the after-corona was welcomed, we have made a significant recovery by actively visiting related institutions and have been able to collect a total of 1,038 lithic measured drawings and 11,200 digital images. In addition, within the term of the assignment starting in FY2019, we have published 15 papers, 4 single-authored books (including 1 commercial book of 576 pages, and 3 academic books of scientific research results totaling 451 pages), co-authored 1 book, and delivered 3 lectures (120 minutes each). It can be said that, from these many results, we were able to clarify some of the contours of the "Tsushima Warm Current Belt Zone" proposed by the principal investigator and the peculiarities related to early agriculture (proto-farming).

Academic Significance and Societal Importance of the Research Achievements

今回の研究成果により、わが国における初期農耕（原初農耕）関連具類の出現期に関する実態、対馬暖流ベルト地帯内における関連資料群の偏在傾向について、明確にすることができた。同地帯内の土器群に対する研究も進めたことで、対馬暖流ベルト地帯の輪郭と特殊性についても明らかにできた。成果を論文や著書のかたちで纏めただけでなく、対馬暖流に沿う各地の博物館での成果発表（講演会スタイル）により、学界、および市民一般に対して、広く公開を果たすことができた。本課題により見出された「対馬暖流ベルト地帯」は、先史時代におけるわが国への大陸文化導入の程度を改めて捉え直す転機へと繋がっていくことだろう。
