Travel and Terrain Advice
Dangerous avalanche conditions. We need to be very alert for storm slabs affected by westerly winds. The condition of the interface between new and old snow, or instability within the new snow, must be carefully assessed. The easiest and most effective means of avalanche safety is to choose slopes with slopes of 30° or less. Also, consider whether there is a large start zone above you. For little experienced skiers, this is a good day to enjoy fresh powder snow in the ski area. Please ski only on courses where skiing is permitted. There have been no avalanche fatalities in Japan in the past 25 years on open runs in ski resorts. This is a proud achievement compared to ski resorts in Europe or North America. This safety is protected by the ski patrol on a daily basis.
