Outline of Final Research Achievements

This study focused on representational artifacts of the Yayoi period to investigate the historical significance of Yayoi mounded tombs in the central Kibi region. The representational artifacts are a material for which research progress has been delayed due to the lack of examples. In particular, we have conducted basic research on the representational artifacts (i.e., house-shaped pottery and bird-shaped pottery) excavated from the Kumoyama-toriuchi Yayoi mounded tombs at Okayama City, which were investigated from 1983 to 1985 by the Okayama University Archaeology Laboratory, using three-dimensional measurements with a digital camera (SfM-MVS) and nondestructive X-ray fluorescence analysis. In addition, we promoted nationwide basic research on house-shaped pottery.

Academic Significance and Societal Importance of the Research Achievements

本研究は、未報告資料であった岡山市雲山鳥打墳丘墓群（１号墳丘墓）の家形土器および鳥形土器の基礎的整理を行うことで、希少な形象遺物群の事例を増やすことを可能とした。また、家形土器の全国的な基礎研究に寄与することを可能とした。さらに、吉備中枢地域の歴史的意義に関し、当地において弥生墳丘墓を中心に形象遺物が密に分布する現象に着目することで新たな研究視点を示した。あわせて、三次元計測等に関する方法論的試行を重ねることにも貢献した。
