• Between 1991 and 1998, seven Japanese monkey Macaca fuscata troops in the Nikko and Imaichi area of central Honshu, Japan, were monitored using radio telemetry. This was in order to clarify whether the phenological progression of the dwarf bamboo Sasa nipponica shoots affects seasonal migration or not, and to identify any relationships between the scale of seasonal migration and environmental and other factors. Although home range size varied, ranging from 5.9(km)^2 to 26.8(km)^2, it was significantly correlated with troop size (r=0.83, n=7, p<0.05). Six out of the seven troops monitored made seasonal movements from lower elevation areas in winter to higher elevation areas in summer-seasonal altitudinal migration. Seasonal changes in the availability of the shoots of S. nipponica were considered the likely cause of seasonal migration. It was concluded that, at least in the study area, the actual scale of seasonal migration is determined by topography, vegetation, snow accumulation, land use by humans, intertroop social relations and the availability of human foods.
