The adaptive strategy and resource exploitation during the Last Glacial Maximum in the eastern Japanese Archipelago

Lithic use-wear analysis is the method to infer the use motions of stone tools and their worked materials, based on the observed physicochemical alternations on flaked surfaces. However, the lithic use-wear studies of the Japanese Palaeolithic artifacts have often focused on an estimation of artifact-specific functions in which use motions and worked materials are the major concern. In this study, the adaptive strategy and resource exploitation during the Last Glacial Maximum in the eastern Japanese Archipelago were discussed, based on a comparison of the results of lithic use-wear analysis and paleoenvironmental data.
