First Snowfalls on Japan’s Mountains in 2020


A summary of the first snowfalls on major mountains across the country according to the Japan Meteorological Agency and local weather stations.

The first day of snowfall is recorded as the date following the end of summer when snow is first observed near the summit of a mountain by the local weather station located at the base. Every year, from early September through mid-December such reports come in for peaks across Japan.

In an average year, the first snowfall for Mount Fuji (3,776m) is September 30. The mountain where snow is always reported the earliest is Mount Asahidake (2,291m), the highest peak in Hokkaidō. In 2020, the first snowfall on this peak came on September 26, one day later than usual. Two days later, on September 28, Mount Fuji had its first snowfall.

A look at first snowfalls recorded on major mountains in Tōhoku and further south for this year shows that snow fell on the Hakkōda Range in Aomori Prefecture on October 15, two days earlier than usual and Mount Nantai in Tochigi Prefecture got snow for the first time twelve days sooner on October 18. On the other hand, the Tateyama Range in Toyama Prefecture saw snow nine days later than usual on October 17.
