This research is aimed to identify the characteristics of an urban structure that is thought to contribute to the heat island phenomena by statistically analyzing the urban plan information, such as building and land uses. First, fifteen items of urban information were arranged into 500 mesh using the Tokyo Metropolitan GIS, and exercised a main ingredient analysis. Next, using the result of the main ingredient analysis, a cluster analysis was exercised in order to attempt to categorize the urban structure. Moreover, by comparing the observed temperature of the Tokyo Metropolitan air pollution agency, the relevance between the urban structure and temperature was examined. Conclusions gained by this research are as follows. 1) As a result of the main ingredient analysis, components that regulate the urban structure are the level of urban development as a No.1 main ingredient, and the building heights as a No.2 main ingredient. 2) A cluster analysis from the No.1 and No.2 main ingredient score, the structure of Tokyo Metropolis was categorized into six district-patterns. 3) The result gained by comparing the score of mail ingredients and observed temperatures in the summer showed that both No.1 and No.2 main ingredients score had good relevance with night temperature but less relevance coefficient when it comes to the daytime.
