We analyzed the relationship between changes in the distribution of Raccoon dogs, Nyctereutes procyonoides viverinus Temminck, and habitat preferences using GIS. Applying principal component analysis and cluster analysis, we classified land use in Kanagawa Prefecture in 1984 and 1994 into 8 types : woodland, farmland, residential, urban, industrial, mosaic of woodland and farmland (MA-I), mosaic of woodland, farmland and residential (MA-II), and mosaic of farmland and residential area (MA-III). We used Ivlev's (1955) selective coefficient to understand the relationship between distribution and landscape classification. Raccoon dogs significantly preferred farmland, MA-I and MA-II in 1982, 1987, and 1992. The distribution of Raccoon dogs is expanding into urban area (residential, urban, and industrial areas) from "natural" areas. This shows that Raccoon dogs can use urban area as habitat in addition to "natural" areas.
