Research Abstract

Radiocarbon measurements of Japanese tree rings from Yayoi to Kofun period were carried out to establish Japanese calibration curve for precise dating. Although the attempt was not successful for the spatial variation of 14C concentration of atmosphere, the 14C anomalies appeared in the tree ring of Eastern Asia were in good agreement of the shape of IntCal representing the 14C variation of North hemisphere. This may suggest the global atmospheric change affects the regional offset of Japanese calibration curve.
