稜線は氷点下で凍結。強風に注意

Mount Akatake summit is mostly clear, but temperatures remain severe at -6.5 degrees Celsius, feeling like -12.4 degrees Celsius. While daytime temperatures will hover around 0 degrees Celsius, gusts are predicted to be strong, ranging from 16 to 18 meters per second until around 3 PM. On the ridges, the wind chill will frequently drop below -10 degrees Celsius. With a nearly 10-degree Celsius temperature difference from the base, a sharp drop in cold will be felt as elevation increases.

Although current snow depth is 0 cm, considering the daytime temperatures and wind speeds, many sections of the rocky ridges, including the chain sections on the Bunzaburo-one and Jizo-one routes, are likely to be frozen. It is possible that shaded or wind-exposed areas may even have icy patches. Light crampons or microspikes are essential, and depending on conditions, using 10-point crampons or more should be considered.

For layering, a moisture-wicking base layer should be worn under mid-layers such as fleece or light down, topped with a windproof and waterproof outer shell. This is akin to winter mountaineering attire. Gloves, a knit hat, and a neck gaiter are also crucial to cover all exposed skin. The risk of losing balance due to strong gusts and hypothermia is high, so constant attention to body temperature management and footing is required during activity.

While the risk of lightning is low, the dangers of strong winds and hypothermia are high. Extreme caution is necessary, especially when traversing the chain sections of Bunzaburo-one and Jizo-one, due to the combination of ice and strong gusts. Avoid pushing limits, choose routes less exposed to wind, and be prepared to make a calm decision to turn back if conditions warrant it.
