Outline of Final Research Achievements

In previous pottery studies based on the unit of pottery styles, it was difficult to capture the movements and whereabouts of the people who immigrated during the early to middle stages of the Yayoi period. In order to address this issue, this research attempted to reconstruct the transmission trajectory of the unit based on pottery types. As a result, it was possible to identify 4 distinct stages between the so-called "Etsuji SX-1 phase" and the Itaduke I , and 11 stages between the Itaduke IIc and epi-Sugu. Consequently, it became clear that there was a migration from eastern Japan to Kyushu during the early stage, and a fundamental reassessment of the influx periods of Kimhae-style pottery coffins and cast iron artifacts became inevitable during the middle stage.

Academic Significance and Societal Importance of the Research Achievements

本研究課題の学術的意義は，渡来人の列島内での動きに見通しがついたことにより，これまでの日韓交渉像の見直しを迫った点である。第一に，我が国の社会構造を一変させた弥生時代開始問題については亀ヶ岡式文化圏を含む列島全土を射程として検討する必要が出てきた。また，中期に関しては青銅器副葬の開始＝金属器文化の開始，鋳造鉄器の流入・拡散といった問題の見直しが必要になり，日本・韓国共同で取り組む研究が必要となった。
