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 →

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 the beginner slope, while T-bar lifts serve the intermediate and advanced terrain. The hill is floodlit after dark, and enquiries go to the town's board of education. It is in Yunotai, a district with rare carbonated hot springs, also home to the town's public baths, Yunotai Onsen.

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.
Only 23% of the vertical on the runs descends to the north or east. The most common direction is south (76%).

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 |
|---|---|---|---|
| Furusatonomori Ski Area | 17.0 km | 159 cm | 1553 |
| Greenpia Onuma | 41.0 km | 169 cm | 1427 |
| Hakodate Nanae Snowpark | 49.0 km | 153 cm | 1621 |

The most snow falls in January. March brings 48% of January’s snowfall. That is in line with the median for ski areas in Japan (52%). In amount, March brings 37 cm, less than the median of 46 cm.
Across the 12 winters measured, the average is 240 cm, and 8 of them fell short of it. The leanest was 2016/17 with 156 cm; the biggest was 2024/25 with 337 cm (2.2 times as much). For 63% of the 397 ski areas in Japan the leanest winter was 2015/16; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.
