Asarigawa Onsen Ski Resort is a ski area in Hokkaido, Japan, on slopes between roughly 145 and 634 m. Its mapped area is about 2.5 km across, with 18 marked runs and 4 lifts (about 7.1 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 293 cm of snowfall a season, 154th of the 397 ski areas we measure in Japan. Its winters are fairly steady; even the leanest, 2015/16 (209 cm), reached 71% of the average. January is usually the snowiest month, with about 85 cm. Snowfall days average −4.9 °C at mid-mountain, and its snow-quality score ranks 49th of 397 in Japan.
Below are links to 2 official live cameras.

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 deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.

Winter by winter
Across the 12 winters measured, the average is 293 cm, and 4 of them fell short of it. The leanest was 2015/16 with 209 cm; the biggest was 2021/22 with 373 cm (1.8 times as much). For 63% of the 397 ski areas in Japan, the leanest winter was the same 2015/16: bad winters tend to hit a whole region at once.

Guides covering Hokkaido
- A Historic El Niño Is Forecast. Here Is What the Last Big One Did to Japan's Snow. NOAA gives a very strong El Niño better than a 90% chance this winter. We measured every Japanese ski area across the last 12 winters: El Niño winters ran 88% of normal, and the strongest of the twelve left Japan at 63%. But Hakuba held 92% of its average that winter while Niseko fell to 57%.
- Which Famous Ski Resorts Actually Get the Most Snow? 24 Names, Measured Niseko is 526th in the world for snowfall. Zermatt is 554th, Jackson Hole 924th, Aspen 1,201st. Measured identically across 3,069 ski areas, the names everyone books and the places it actually snows turn out to be two different lists.
- Australia Just Had Its Worst Season in Twenty Years. Here Is What Japan's 12-Winter Record Says About Booking It Instead. Snow depth at Spencers Creek peaked at 94.5 cm, the third lowest since 1954, and resorts closed in August. Our own measure — snowfall, not depth — puts Australia at 50% of its 12-year average. The gap between those two numbers is the story: it was the warmth, not only the lack of snow. New Zealand, meanwhile, finished at 108% of normal.
