This study aims to analyze the capacity of 'urban green area of Japan' within urban or suburban residential or open space area as a potential carbon sink for Kyoto Protocol. The study was carried out according to the follows steps: 1.Counting the number of 'rban green areas in Japan' from mesh data from "Japan's national vegetation survey". 2.Calculating a sample percentage canopy cover from the analysis of aerial photographs. 3.Calculating average canopy cover of 'urban green areas'. Result for the average of tree crown coverage was 26.74%, and standard deviation was 16.07. From the results, it could be inferred that the total urban, suburban residential or open space area of Japan is about 1,713km2. Moreover, according to comparisons of results between mesh data and administration data, there was no significant difference in the method of calculating the area by mesh data, and it was suggested that the total forest area can be used as a method for calculating the total.
