Obsidian source provenance of stone tools from the Pleistocene archaeological sites in Hokkaido performed, using EPMA, hXRF and NAA methods, and adding to existing examples of the source provenance so far, obsidian tool distributed pattern of each source was analyzed. At the same time, elucidating the geological formation process of obsidian generation, and determining the standard chemical composition of elements from each obsidian source, standardization of archaeological obsidian source provenance study is archived. On the basis of these researches, actual situation of obsidian exploitation and circulation in the circum Japan Sea area is clarified, and the epochal timing on these patterns led to be delineated the dynamics of Pleistocene human societies.
