IOX-AROSA

イオックス・アローザ

IOX-AROSA is a ski area in Toyama, Japan, on slopes between roughly 286 and 805 m. Its mapped area is about 2.0 km across, with 9 marked runs and 6 lifts (about 4.7 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 314 cm of snowfall a season, 145th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2017/18 (463 cm), brought more than twice as much as the leanest, 2019/20 (156 cm). January is usually the snowiest month, with about 119 cm. Snowfall days average −1.5 °C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 283rd of 397 in Japan.

The nearest city of any size is Kanazawa, about 16 km away. Below are links to 3 official live cameras.

Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.

What we have measured at IOX-AROSA

Shirakawa-go's Snow Falls at Around 0°C. That Is Why the Roofs Are 60 Degrees. Japan has thatched villages all over the country, and only one of them built roofs like praying hands. We measured the snow at four of them: Shirakawa-go gets twelve times Miyama's depth, and it arrives at the heaviest temperature snow can fall.
The Deepest Snow You Can Sleep in an Old Japanese House Is Not Shirakawa-go We measured the snow at seven villages where you can stay in traditional architecture, and how far each is from a lift. Shirakawa-go is 15.6 km from a middling ski hill. Shiozawa is 2.2 km from the world's =67th snowiest.
