Assuming that influences of the land use on the temperature distribution characteristics in the district is significant, six kinds of isothermal graphs covering Tokyo metropolitan area were presented, using detailed numerical geographical information. By statistical analysis, multiple regression equations for design outdoor air temperature derived AMeDAS data against land use frequency, altitude and distance from seashore, were obtained. Validity of the proposed isothermal graphs was confirmed comparing with six kinds of isothermal graphs covering the 100km Tokyo district proposed in authors' recent study. Regarding isothermal graphs in this study, high accuracy near seashore was supposed and any singular distributions were not recognized.
