Consistently low temperatures and a deep, uniform snowpack generally keep the avalanche danger fairly low across Japan’s mountains, but that doesn’t make the area anywhere near risk free. Entering the backcountry should always be done with utmost respect for the dangers, and only by those with proper gear, training, and guides.
This skier managed to trigger an enormous avalanche in the backcountry around Hakuba in Japan. They apparently knew the risk of a slide and had friends in a safe place ready to perform a rescue if necessary. Fortunately they weren’t caught and nobody was hurt, but let this be a reminder that an avalanche risk can exist anywhere where there’s snow.
Colorado Avalanche Information Center Basic Avalanche Safety:
Avalanches are possible any time you have snow on a slope. The best thing you can do before you head into the mountains is check the avalanche forecast.
If you are traveling where there isn’t a current avalanche forecast, here are some simple things that will help you avoid avalanches.
- Avalanches are possible when you have snow on a slope steeper than about 30 degrees.
- Most avalanches happen during or soon after a big snowstorm, period of strong winds, or during a thaw (rapid increase in temperature).
- Signs of higher avalanche danger include recent avalanches, cracking in the snow, and audible collapsing. Avoid traveling on or under similar slopes.
