Hakkai Sanroku Ski Area is a ski area in Niigata, Japan. The terrain spans roughly 200–409 m above sea level. The mapped ski area covers about 1.1 km². Within 2.4 km of the centre, the map shows 6 marked runs and 2 lifts, totalling about 3.3 km of piste. There is no settled snow at the moment — the season has not started here yet. Over the last three winters the ERA5 reanalysis gives it 492 cm of snowfall a season, 75th (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. The nearest city of any size is Niigata, about 85 km away. 1 official live camera is linked below. 130 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.

The tick marks the median across the 395 Japanese ski areas. 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.

What was actually measured nearby
Total snowfall from December to March recorded at the 小出 weather station — 7.7 km from this ski area, 206 m below its mid-slope.
| Three-season average | 596 cm |
| 2023/24 | 412 cm |
| 2024/25 | 699 cm |
| 2025/26 | 676 cm |
The figure calculated on this page is 492 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.

Hot springs nearby, as analysed
2 hot spring sources with published analyses lie within 5 km of this ski area, nearest first (the hottest is 27.6 °C).

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.
