Google Translated Description
The three distressed persons and four friends moved from Kirolo Snow World Ski Resort to the northeast slope of Yoichi-dake by two snowmobiles and started skiing, but the weather worsened around noon, so the four friends went down the mountain first. However, the weather deteriorated around noon, so four friends descended by snowmobile and were scheduled to pick up the three people in distress again by snowmobile, but they could not pick them up due to poor visibility caused by a blizzard, so the three people in distress created a snow cave on a snowfield at an altitude of around 1270 meters and bivouacked there for two nights. At around 7:25 a.m. on March 3, the Hokkaido Police Mountain Distress Rescue Team and the Ground Self-Defense Force search team found and rescued the three distressed persons.
