Chateraise Ski Valley Nobeyama is a ski area in Nagano, Japan, on slopes between roughly 1,407 and 1,624 m. Its mapped area is about 1.1 km across, with 7 marked runs and 3 lifts (about 3.5 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 113 cm of snowfall a season, 368th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2014/15 (154 cm), brought more than twice as much as the leanest, 2025/26 (55 cm). March is usually the snowiest month, with about 44 cm. Snowfall days average −3.2 °C at mid-mountain, and its snow-quality score ranks 302nd of 397 in Japan.

Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.
Elevation range is estimated by sampling points across the ski area.
How much snow it gets
Measured by us across 3,069 ski areas by one identical method. 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 deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.

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.

- 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.
- How Japan's Early-Bird Lift Tickets Work: At Hakuba Happo-One, Eight of the Nine Need a Japanese ID Card Hakuba Happo-One opened early-bird sales at 10:00 on 1 October. A day costs ¥6,400 against ¥9,800 at the window, 35% off. But every ticket on the list except one needs a My Number Card and a Japanese phone app. A visitor from abroad can buy exactly one of them, at 15% off.
