Abstract
During 1986-93. studies on the home range and the dispersal of Nyctereutes procyonoides viverrinus using the radiotelemetry were performed at Nyugasa-yama (Mt. Nyugasa). Nagano Prefecture, located at the subalpine belt. The average area of home range calculated by the minimum convex polygon method was 609.5 ha. Some adult males had the larger home range in their mating season. Both males and females had the smaller home range in their delivery and suckling season. Adults moved within a short distance of less than 2 km. However, 66.7 percents of 0-year-old individuals were observed to move by a relatively long distance of more than 2 km during their first autumn to the following spring.
