Travel and Terrain Advice
Be careful of slipping on hard, frozen slopes. Rough slopes are extremely difficult to ski on because they are frozen. If you choose a clean, unrough slope during the time when the snow surface is soft, you can enjoy comfortable spring corn snow. Slopes with glide cracks at low altitudes are high-risk conditions (low probability of triggering, high consequence). Do not enter slopes with cracks, and when passing under such slopes, leave an appropriate distance between you and your companions and move quickly. Have a nice day.

Frozen snow surface does not mean safety. Stay away from cracked slopes.

Evaluate as of morning. Pay attention to the decrease in surface snow intensity during the day.
概要
Avalanche
A number of loose snow avalanches of size 1-1.5 were reported yesterday (14th) in the below treeline. These avalanches were spontaneous and caused by ski cuts. Size 1 glide avalanches were also reported.
Snowpack
Melt-Freeze cycles have resulted in the formation of slippery coarse snow on the south side. On the north side, due to wind and other factors, the slopes are mainly hard and frozen. At very low elevations, the lower layers of snow cover are very wet.
Weather
The Japan Meteorological Agency is forecasting southerly winds, daytime and northerly winds, cloudy, with a daytime high of 7 °C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -6 °C (as of 4:45 a.m.), with no new precipitation in the past 12 hours.
