Accurate knowledge on marine reservoir effect is particularly important to estimate active periods of archeological sites in Japan. Since most of archeological sites are situated in an alluvial plain in Japan, archeological remains include inevitably marine products. To obtain precise calendar ages for marine samples such as shell fragments and sea mammal bones by ^<14>C dating, a correction for marine reservoir effect is necessary. In addition, ^<14>C ages on a collagen fraction extracted from human bones should be corrected for the sources of their diet, the uptake ratio of terrestrial food to marine one. However, the local fluctuation of marine reservoir effect around Japan Islands is not known well. This study gives a brief summary of a calibration method for ^<14>C ages of samples containing marine-derived carbon.
