At its heart is a single broad slope that stretches up to 400 metres across. For stronger skiers, a run actually called Off Piste is deliberately left ungroomed. The area stands beside Route 186, at the point where the road crosses the prefectural line from Hiroshima into Shimane.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).

When it falls, and how winters differ

Month by month

The most snow falls in January. March brings 36% 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 16 cm, less than the median of 46 cm.

What was actually measured nearby

Total snowfall from December to March recorded at the 八幡 weather station — 5.5 km from this ski area, 91 m below its mid-slope.

Three-season average442 cm
2023/24367 cm
2024/25691 cm
2025/26267 cm

The figure calculated on this page is 139 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.
