Guides
Learn where to find avalanche forecasts in Japan, how to interpret avalanche information, and why checking conditions is an essential part of planning any backcountry ski or snowboard day.
For anyone planning to ski or snowboard in the backcountry, checking the avalanche forecast should be part of every day's preparation.
Avalanches are a natural mountain hazard, and understanding current conditions can help you make more informed decisions about where and how you travel. While no forecast can eliminate risk entirely, having up-to-date information is far better than heading into the mountains without understanding the current conditions.
If you're new to backcountry travel, we also recommend reading our guide to off-piste safety.
NADARE Avalanche information
NADARE is one of the most useful resources for skiers and snowboarders looking for avalanche information in Japan.
Different avalanche forecasters contribute information to the platform, helping map avalanche danger across multiple regions. Forecasts are region-specific and provide information on hazard levels, problem types, and how avalanche risk may vary depending on elevation and slope aspect.
Before heading into the mountains, check the forecast for the specific region you plan to visit rather than relying on information from another area.

Avalanche Forecasts Are Information, Not Guarantees
One of the most important things to understand about avalanche forecasts is that they do not make terrain safe.
Even on days when avalanche danger is rated as low, avalanches can still occur. Forecasts provide an assessment of current conditions and highlight areas of concern, but mountain environments are constantly changing. Wind, snowfall, temperature fluctuations, and terrain all influence avalanche risk.
The goal of reading an avalanche forecast is not to find a day with zero risk—it is to better understand the hazards that may be present and make more informed decisions as a result.
