Google Translated Description
The three victims and their four friends moved from Kirolo Snow World Ski Resort to the northeast slope of Yoichi-dake by two snowmobiles and started skiing. 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.

Original Japanese Description
遭難者3人は、友人4人とキロロスノーワールドスキー場からスノーモービル2台で余市岳北東側斜面に移動してスキーを始めたが、正午頃から天候が悪化したため、先に友人4人がスノーモービルで下山し、再度、スノーモービルで遭難者3人を迎えに行く予定だったが、吹雪による視界不良のため迎えに行くことができず、遭難者3人は標高1270メートル付近の雪原上に雪洞を作成し、同所で二晩ビバーク。(※3月3日午前7時25分頃、捜索中の道警山岳遭難救助隊及び陸上自衛隊捜索部隊が遭難者3人を発見、救助)
