In radiocarbon dating, it is necessary to correct the measured radiocarbon ages to calendar ages based on a calibration curve. The IntCal calibration curve applied to terrestrial materials in the Northern Hemisphere has been developed mainly on the basis of tree ring materials from Europe and the United States, but research in Japan has also played a major role, such as the varved sediment of Lake Suigetsu, Fukui Prefecture, and the Japanese tree rings used in IntCal20. The history of the latest calibration curve IntCal20 is outlined, focusing on the efforts made in Japan.

Key words: radiocarbon dating; dendrochronology; calibration curve; Japanese tree rings; regional effect
