The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure

This ski area lies on the national highway, close to the centre of Monbetsu. The slopes look out over the Sea of Okhotsk, and in the drift-ice season you ski with the floes on the sea below. There is also a snowboard park with a kicker, and a bobsleigh run for beginners. Sources: mombetsu.jp, tic.mombetsu.net (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)

The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).

How these figures are made

What was actually measured nearby

Total snowfall from December to March recorded at the 紋別小向 weather station — 7.5 km from this ski area, 163 m below its mid-slope.

Three-season average378 cm
2023/24366 cm
2024/25378 cm
2025/26390 cm

The figure calculated on this page is 181 cm.

A weather station is not a ski slope. We picked one at a similar elevation, but it stands in a valley or a village. More snow falls on the mountain above it. We have not tried to guess how much more.
