Not open yet for 2026/27. We have not yet found an official opening date. The snowfall below is a model figure and does not mean the slopes are skiable.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
This season so far (1 Nov to 9 Nov): 18 cm, 161% of the average for the same dates. The average is over twelve winters on the same weather model. Across Japan →

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
A rope tow serves this gentle, town-run slope. It suits children learning to ski. Ski classes are held here too. Sources: suttufan.com, town.suttu.lg.jp (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)
Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.
100% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
Source: OpenSkiMap (© OpenStreetMap contributors, ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Vertical is the difference between the highest and lowest points of the mapped runs and lifts.
This ski area does not put a camera on its own slopes. The nearest live view is the road below.
Footage remains the copyright of each operator. JAPANSNOWLINE neither stores nor redistributes it.
Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
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).
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Iwanai Resort | 29.0 km | 373 cm | 219 |
| Niseko Moiwa Ski Resort | 34.0 km | 289 cm | 526 |
| Pirika Ski Resort | 37.0 km | 242 cm | 787 |
| Niseko Grand Hirafu | 39.0 km | 289 cm | 526 |

For those cheap spring weeks, we add which way each resort's slopes face.
