The purpose of this study is to evaluate forest and residential area distribution based on externality. For this purpose, we employ hedonic approach for calculating appropriate distance from forest to residential area and externality of forest for residential area. And we analyze forest and residential distribution in each 23 ward. The results were as follows. 1) Externality of forest was the most fit to land price when forest from land price point was within 300m. And, partial regression coefficient of the forest cells within 300m from land price point was 320.7. 2) Externality in forest cell to residential area was higher in wards of city center and more forest. In contrast, it was lower in wards of the eastern area of Tokyo and lowland. 3) Externality in residential area cells from forest was higher in wards of the western area of Tokyo and more residential areas. In contrast, it was lower in wards of less residential area. 4) Externality in forest creation assumed cells was higher in wards of more residential area. In contrast, it was lower in wards of less residential area.
