独立峰の風は冷たく。凍結箇所に足元注意

Current conditions at Mt. Fuji summit are partly cloudy with a temperature of minus 2.5 degrees Celsius, feeling like minus 6 degrees Celsius. While the day is expected to turn mostly sunny and temperatures will rise, they will only reach around 0.9 degrees Celsius by noon. During this period, gusts up to 8.1 meters per second are forecast, which could drive the wind chill down to approximately minus 7 degrees Celsius. On the exposed slopes above the tree line, this persistent wind will continuously strip body heat.

The steep volcanic scree slopes starting from the 5th station have zero snow depth. However, with temperatures remaining at or below freezing even during the day, icy patches will persist in shaded or wind-sheltered areas. Extreme caution is advised, especially on exposed rocky sections, to prevent slips and falls. Essential gear includes lightweight crampons or microspikes, a waterproof and breathable outer shell, a warm mid-layer, thick gloves, and a hat. Always be mindful of the risk of altitude sickness and avoid pushing beyond your limits.

Temperatures will drop again from evening into night, reaching minus 4.8 degrees Celsius by midnight. Although winds will subside, the felt temperature will become even more severe. Throughout the day, continuously monitor changes in visibility and temperature. Be prepared to turn back promptly if conditions deteriorate. Prior to the official summer climbing season, trails are not yet maintained, requiring preparations akin to winter mountaineering.
