To examine the distribution characteristics of snow deposition in relation to meteorological conditions, nine automatic stations have been installed in the area from central Hokkaido to Toyama Prefecture, covering most of the area which has large amounts of snow accumulation in Japan. Special care was taken to have several stations located at high elevations where no snow/meteorological data have been available in the past. This report presents data from the 1991-1992 winter season obtained at these automatic stations. It was a rather warm winter, compared with an average year, and the deposited snow was relatively slight at low elevations; the maximum snow depth being ca. 1.0 m. At stations located at a little over 1000 m a.s.l., the maximum snow depth ranged from 3.3 m to 4.5 m. At Murodo (2400 m a.s.l.), the highest observation site in the Tateyama Mountains, the maximum snow depth was the greatest, as high as 6.8 m in early May when most of the snow at the other sites had already melted.
