The best snow falls around Kiroro and Sapporo Kokusai, each on 14 cm, with Niseko United close behind on 13 cm. The storm runs from Tuesday 27 Oct to Thursday 29 Oct and peaks on Wednesday 28 Oct. The regional average is 7.2 cm, but the spread is wide, from 0.1 cm at the least favoured resorts to 14 cm at the best. Precipitation falls over about 38 hours.
The freezing level ranges from 360 m to 1,680 m. At its lowest it is close to the valley floor, so snow could fall at low elevations. Rain could mix in at resorts whose listed elevation is below the freezing level, such as Sapporo Moiwa, Bankei Ski Area and Otaru Tenguyama.
The westerly flow is the main hazard. Gusts could reach 93 km/h, lifts are likely to close and visibility is likely to be poor. It feels like -13°C at Kiroro on Wednesday 28 Oct.

No resorts are in season on their scheduled dates today, with 10 in pre-season, and none are scheduled to open in the next 14 days. The next opening is Sapporo Kokusai, scheduled to open on 20 Nov. "In season" refers to the resort's scheduled calendar, not a live lift report.
No resorts are in season yet. Dates are from each resort's season calendar, not a live lift report.
Snowfall and freezing levels are forecast at upper-mountain points for each resort, so real totals can differ where terrain lifts or shelters the weather. Treat figures as a guide to timing and scale, and check each resort's own page before you travel.
SnowStash calculates every figure from its own forecast data. The wording is drafted with AI from those figures and checked before publishing, with this edition reviewed by Michael Fulton.
