Accelerator mass spectrometry (AMS) is a useful method for radiocarbon dating of charred-carbonaceous material on the potsherd. The carbonaceous material attached on inside or outside surface of the sherd is residues of food or soot from fuels used at the time of cooking. Therefore, the calibrated ^<14>C age should be the age of pottery usage. The purpose of this study is to provide AMS ^<14>C ages for the pottery samples of the Yayoi and Kofun periods in Aichi and Ishikawa Prefectures. The samples had been excavated from Tukinawate, Asahi, Kadomanuma and Hachioji sites in Aichi Prefecture as well as Fujie-B, Yokaichi-jikata, Shimoyasuhara, Higashi-matoba-takenohana, Nekohashi, Ohtomo-nishi, Ohnagano and Sendai-nomi sites in Ishikawa Prefecture, central Japan. ^<14>C/^<12>C and ^<13>C/^<12>C ratios of 56 pottery samples were measured with AMS. The AMS ^<14>C ages were calibrated to calendar dates by using the INTCAL98 data. The calibrated ages of pottery samples were compared with their archeological ages. The starting age of the middle Yayoi period in Aichi and Ishikawa Prefectures was assigned to around BC 4^
