| Outline of Final Research Achievements |
The present research discussed the process of appearance of Upper Paleolithic in Japanese Archipelago, through examine the northern route for the first modern human in the Last Glacial from Archaeological and Anthropological point of views. Hunter-Gatherer were targeted group mammals that inhabited cold grass-land and open forests during the LGM, particularly about 26,000-22,000 cal yr BP. However, the change at the LGM was not just a replacement of the small flake industry by microblades, but a divergence of the Flake-based, Blade-based, and Microblade-based toolkits.
In addition with these result, the late Pleistocene radiocarbon chronology of the Transbaikal to conclude that humans completely abandoned the area between 25,000 and 22,000 cal yr BP, suggested us Hokkaido to serve as a refuge and the origin of microblade technology.
