Snow depth, newly fallen snow depth and weather have been observed continuously at the Shinjo Branch of the National Research Center for Disaster Prevention since November 1974. Shinjo Branch, 38°47′N, 140°19′E, 127m above sea level, is located at the center of the Shinjo Basin which is situated in the northern part of Yamagata-ken, Japan. Snow depth, newly fallen snow depth and weather were observed at 9 o'clock every day with the naked eye. The daily data on these meteorological elements from November 1974 to April 1984 is included in this paper. The mean and maximum values of the maximum snow depth for ten winter seasons are 1.41m and 1.83m on Feb. 28, 1981, respectively. The maximum value of the newly fallen snow depth in these ten years was 60cm on Jan. 31, 1981. The total number of days when snow fall was observed during these ten years was 768 days. Of these 768 days, newly fallen snow depth below 5cm was observed on 301 days (39.1% of the 768 days), and newly fallen snow depth between 41cm and 60cm was observed on 4 days (0.5% of the 768 days) in this ten year period.
