We investigated that the climatic factors controlling the stable carbon isotopic composition of annual rings of Japanese cypress (Chamaecyparis obtusa). Four grubs with more than 100 rings, which were collected at a coastal region of Lake Biwa, were used for isotopic analysis. The δ^<13>C values of annual rings from 1936 to 1987 were measured in the all four samples. There was little spatial δ^<13>C variation of annual rings in the present study area within a radius of 15 km, since the correlation coefficients in interzonal comparison (r=0.52 to 0.69) were identical with those of the individual variations in one forest (r=0.57 to 0.70). This result suggested that the δ^<13>C values of annual rings were mainly influenced by the extensive environmental factors at least 30 km. The δ^<13>C fluctuations of annual rings from the secular trends were compared with the monthly meteorological data, i.e., temperature, precipitation, number of precipitation days and sunshine duration, and showed the best correlation with sunshine (positive, r=0.44) and precipitation (negative, r=-0.32) in early summer.
