Reorganization of prehistorical structure of calendar age and evaluation of climate change effect in Japanese archipelago using tree ring oxygen isotope ratios
Description: In cooperation with centers of archaeological operation over Japan, while performing the spatiotemporal expansion of master chronology of the tree-ring oxygen isotopic ratio and the precise reconstruction of past climate change, we proceeded with the dating of a large amount of excavated woods by the oxygen isotopic dendrochronology, introduced the calendar age to the pottery chronology, which is the basis of archaeological chronology in Japan, and reexamined the entire prehistoric image of Japan with a focus on the relationship with climate change. At the same time, we released the master chronology of the tree-ring oxygen isotope ratio in an international academic database, and transferred complete technologies of the oxygen isotopic dendrochronological method to public and private parties in Japan and Asia.
