During the Terminal Pleistocene in central Honshu, which coincided temporally with the emergence of pottery, lithic raw material reduction sequences ceased to be rational and economical, instead becoming expedient and wasteful. Furthermore, hunter-gatherers had stopped importing lithic raw materials over long distances, and attempts made previously to attain a maximum number of usable edges on artifacts upon one nodule had ceased. Their reduction sequences might have no longer required a sparing strategy, since they now used abundant local raw materials, probably due to reduced mobility. It is suggested that the emergence of pottery allowed them to exploit more diverse plant sources and enabled them to survive within smaller territories, while the lithic reduction strategies changed as they adapted to use of available lithic raw materials.
