The Haccho-zaka route, known for its steep incline, should be relatively stable today due to the dry conditions and minimal wind. However, even on a calm day, it is crucial to remain vigilant on this 3000m-class mountain, as weather can change rapidly and temperatures can drop suddenly.

No significant risks have been detected by the automated risk assessment. The risk of thunderstorms is low, and no strong winds are anticipated. While the daytime feels-like temperature is expected to range from 7°C to 12°C, proper layering is vital to prevent hypothermia at an elevation of 2933.24m, especially during stops or unexpected weather changes. A wicking base layer, a light fleece mid-layer, and a windproof outer jacket are mandatory. An additional insulating layer, such as a light down jacket, is recommended for breaks or early morning ascents.

By 6 PM, the probability of precipitation rises to 55%, though predicted rainfall remains 0mm, suggesting light drizzle or mist. Overnight, temperatures will drop to around 6°C. Ensure you have adequate warm clothing and plan to descend before sunset. Rain gear is essential.
