Snow depth, new snow over the last 7 days and the 7-day snowfall forecast for 22 Japanese ski areas, updated each week. Latest update: October 19, 2026.

This report is rebuilt every week from Open-Meteo data via our weather API. This update was generated on October 19, 2026 (Japan time) and covers 22 ski areas in Hokkaido, Tohoku, Nagano, Niigata and western Japan.

New snow is the total for October 12 to October 18, 2026. The forecast is the total for October 19 to October 25, 2026. Snow depth is the Open-Meteo model value for the grid cell around each resort, about 11 km across, so it can differ from the depth a resort reports for its slopes. Check the resort's own report before you travel.
