No snow yet. Not open yet for 2026/27. We have not yet found an official opening date. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
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 →
On display in the grounds is the Moha 1, the oldest wooden electric railcar in Niigata Prefecture, retired when the Kambara Railway line closed. In winter the grounds become a family ski slope, with T-bar lifts pulling skiers to the top of the hill. Sources: city.kamo.niigata.jp, pref.niigata.lg.jp, niigata-kankou.or.jp (sources read 11 Oct 2026; an AI draft the site operator has not yet checked)
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 |
|---|---|---|---|
| Mikawa Onsen | 26.0 km | 363 cm | 243 |
| Nagaoka City Ski Area | 32.0 km | 320 cm | 404 |
| Suhara Ski Area | 36.0 km | 538 cm | 71 |
| Tadami Ski Area | 37.0 km | 482 cm | 91 |
| Koshi Kogen Ski Area | 42.0 km | 433 cm | 127 |

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.
86% 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.
The most snow falls in January. March brings 29% of January’s snowfall. That is a steeper fall than the median for ski areas in Japan (52%): the snow here is concentrated early in the season. In amount, March brings 34 cm, less than the median of 46 cm.
Across the 12 winters measured, the average is 302 cm, and 4 of them fell short of it. The leanest was 2015/16 with 113 cm; the biggest was 2024/25 with 445 cm (3.9 times as much).
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.
