| Outline of Final Research Achievements |
The early Upper Palaeolithic in Japan is characterized by the presence of stone axes, which are dated to ca. 38,000-29,000 cal yr BP. Palaeolithic stone axe are actually made of the tremolite rock (the nephrite), which consists of tremolite and actinolite, and is denser, tougher. They also became able to presume a place of origin and a collection place by judging a stone of a stone axe by stereo microscope.
Axes of the tremolite rock are distributed over 500 km, from Akita to Ishikawa prefecture. Howeve, these stone axes have not been found along the Pacific Ocean coastal areas. These areas were made of green tuffs, greenstones, and greenschists, and some others. I can think movement territory in 2 areas of Pacific Ocean and Sea of Japan existed already then.
