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 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).
Compared with what is nearby
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
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.

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.

Western Japan's ski areas look thin in our data — a median of 125 cm against a national 249 cm. Against 16 Japan Meteorological Agency stations, the model we use returns 44% of what the ground records there. The region is far snowier than our own numbers say.
