So, in this research, radiocarbon concentration measurement and oxygen isotopic ratio analysis of annual rings of age known Yakusugi (a Japanese cedar) from the 1st to the 4th century were conducted, as well as comparison of their concentrations with IntCal09. As a result, in Yakushima, a regional effect was present. The periods in which the regional effect had occurred are: period 1; AD90-112, period 2; AD146-160, period 3; AD180-200. Also as a cause, that two ideas have already been issued: (1) the effect of the ocean surrounding Yakushima Island, (2) the impact of atmospheric effects from the Southern Hemisphere. This result shows the periods 1-3 are subject to the influence of the atmosphere from south. And although possibly it had the influence from the ocean around Yakushima, it resulted in the conclusion that the regional effect is not caused by only this source. Finally, from the consideration result, it was shown that the possibility of the regional effect in the Japanese Islands. Therefore, I thought that it will be necessary to verify which factor is related to the period when the regional effect has occurred, in future., 名古屋大学年代測定総合研究センターシンポジウム報告}, pages = {57--62}, title = {日本産樹木年輪の炭素14濃度測定およびIntCal19との比較検討}, volume = {23}, year = {2012} }
