TOKYO (Reuters) - Investigators pored over a Japanese mountain on Tuesday after a massive avalanche tore through a group of high school students and teachers, killing eight, amid questions about why avalanche warnings were ignored and whether they had proper equipment.
The avalanche in central Japan on Monday, which struck along some 50 metres (150 ft) of a steep slope just above a ski area, killed seven students and an instructor who were part of a 48-person group taking part in winter climbing training.
Thirty-eight people were injured, two of them critically.
Survivors told Japanese media they were training in a wooded area in Nasu, a town in Tochigi prefecture 160 km (100 miles) north of Tokyo, when suddenly there were shouts of "Avalanche, get out of here!" and voices yelling to take cover.
"A second later the snow was there and I was buried up to my chest," said one 16-year-old student. "My face was free, so I managed to get myself out. It was scary."
The students who died, all aged 16 and 17, were from a local high school known for its prowess in competitive mountain climbing and were at the front of the group when the avalanche struck on the final day of a three-day training camp. An avalanche warning was in place at the time.
The father of Kosuke Sato, 16, one of those who died, displayed the torn windbreaker his son had worn.
"I still can't believe it," he told TBS television, choking back tears.
The group changed their original plan to climb a nearby mountain due to heavy snow and strong winds, switching instead to practicing walking in deep snow on a steep slope, media said.
"Spring is much more dangerous in terms of avalanches than winter," mountaineer Ken Noguchi, himself the survivor of several avalanches, said on TV Asahi. Other experts blamed temperature fluctuations and deep, fresh snowfall on top of older snow.
A Tochigi prefectural police spokesman said investigations were focused on whether or not there had been judgment errors, in particular by the Tochigi High School Athletics Federation, which sponsored the training.
He declined to give further details but said investigators were also looking into whether the students had proper safety equipment, including beacons that can help locate those swept up in avalanches.
Atsuhito Masuguchi, head of the Tochigi High School Athletics Federation, said the training had been held for decades.
"It's conducted by our mountain specialists, and we relied on their judgment of conditions and actually carrying out the training. They're the experts," he added.
"We've done this for over 50 years. This was the first accident."
