A connecting run and lifts link the area to the neighbouring Yomase Onsen Ski Area, and one Mt.KOSHA lift ticket covers both. The X-JAM Takaifuji side makes its terrain park the headline attraction, and snowboard freestyle competitions are held there.

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.
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.

97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
The most snow falls in January. March brings 34% 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. For skiing, though, the amount matters more than the share: March brings 69 cm, more than the median of 46 cm.
