Elucidation of the history of coastal utilization of the Setouchi islands, Japan by multifaceted analysis and three-dimensional geological modelling

Abstract

Three of the four main islands in Japan are separated by the Seto Inland Sea in the country's Setouchi region. This area is an important inland sea of Japan and is interesting for researchers in various fields because of its historically active exchange and trade. Associate Professor Keisuke Makibayashi, Research Center for Asian Archaeology of Industry and Culture, Ehime University, Japan, is involved in a project focused on the Miyan'na site, which is a salt-making site from the Kofun period and the Kamakura period on a small island in the Seto Inland Sea in Ehime Prefecture that is seeking to restore the lost landscape. This work involves the use of different research methods such as particle size analysis, soil physics and chemistry analysis, as well as organising a cross-sectional view of the Miyan'na site, performing 3D geological modelling, using scientific data to explain beach ridges and understand historical human activities, and performing excavations. Ultimately, the researchers want to return the landscape to the local community, thereby contributing to the people in the area. The research is also expected to make important contributions to archaeology, history and environmental science.
