Outline of Final Research Achievements

Polished stone axes made of Northern Tohoku of the Yayoi era medium-term are using the Hokkaido green schist. In the Yayoi era mid-term of the Tsugaru Plain it will account for more than 90 percent. Stone of stone ax made of the results of X-ray fluorescence analysis, are estimated to have been collected at Yubari River. In addition, Yayoi era medium-term have been distributed in Hokkaido from also Northern Tohoku of thick shape stone axes. Close relationship of these two regions became clear.
