As details emerged of Monday's devastating avalanche at a ski resort in Tochigi Prefecture, which killed seven high school students and a teacher, an instruction given by a teacher has come under scrutiny.
According to media reports, a supervising teacher shouted "get down" upon noticing the avalanche. Some survivors said they followed the instruction.
But experts say the instruction was completely wrong, as the most important thing to do first is to run away as fast as possible. If they are caught in an avalanche, they should "swim" in an effort to stay as high up in the layers of snow as possible, they said.
