Travel and Terrain Advice
It is a day when you need to be alert to the instability created by stormy weather because it has become a lot of snowfall. It requires careful routing and conservative decision-making. Be aware of convex or isolated places where snow is accumulated under the influence of the wind, and take safety actions by noticing the occurrence areas and tracks within them, even in forest belts. When an avalanche occurs in a forest, even if the scale is small, the trees become a hazard, which leads to serious consequences. When skiing inside the ski area, please observe the skidable area. It's for your safety, and also for the safety of other visitors. Have a safe day
