Travel and Terrain Advice
Today is a day to have fun in the ski resort. Rainy days are more fun than you might think, as the boards run well. Just be sure to take all the waterproof measures you can. To get to the mountains, you will have to pass through rainy areas, wet your clothes and equipment, and then go above freezing level. If your equipment is inadequate, you will be clad in ice armor. Not only is there a danger of avalanche, but also hypothermia and lost due to poor visibility are to be expected. It is New Year's Eve. It is a good idea to take a hot spring bath and eat delicious food with your friends. I wish you all a happy new year!

It remained dry on other orientations in the alpine area. Since this early morning, a few cm of snow has been on top of it above the upper treeline and rain below it.
Weather
The Japan Meteorological Agency forecasts that a low pressure system will move east of Japan through the Izu Islands area and gradually become a winter pressure system with a high in the west and a low in the east.
