By Climbing Season: Clothing and Climate Points
To enjoy mountain climbing in comfort, it is important to select clothing appropriate for each season's climate. On high elevation mountains such as Mt. Asama and Mt. Yatsugatake, the temperature difference from the base of the mountain and changes in weather must also be taken into consideration. Here are some tips on clothing and equipment for each season (spring, summer, and fall).
Spring (April-May)
Spring is a pleasant time for hiking in the mountains, but lingering snow can be seen until mid-April in higher elevation areas. Since the trails can be muddy and icy in some areas, it is safe to carry waterproof shoes and chain spikes. In the mornings and evenings, temperatures can drop close to 0°C (32°F), so we recommend wearing clothing that can be adjusted by layering with a fleece or lightweight down jacket.
Summer (June-August)
Even in the highlands, the sun is strong and temperatures can exceed 25°C during the day. Wicking innerwear, hats, sunglasses, and sunscreen are essential. Insect repellent is also important as the course passes through grassy and marshy areas. Because of the possibility of thunderstorms in the afternoon, it is best to finish your activities in the morning. Always carry lightweight rainwear.
Autumn (September to November)
Autumn, with its beautiful autumn foliage and clean air, is a comfortable season for mountain climbing. However, from October onward, the mornings and evenings become even colder, with temperatures dropping to near freezing. Be sure to pack a windbreaker, down jacket, gloves, and a knit hat to protect yourself from the cold. Especially from November onward, you need to watch out for the first snow and frost.
Sachi Tanaka, a certified Shinshu mountaineering guide:
In highland mountains such as Asama and Yatsugatake, the temperature varies widely not only between seasons but also between morning and night and during the day, and the weather changes quickly, so it is very important to choose the right clothing. In spring, equip yourself for lingering snow and mud, in summer for UV rays and insects, and in fall for full-fledged protection against the cold. The key to comfortable hiking in any season is to wear layers that are easy to put on and take off. Take it easy and enjoy nature with the right equipment for you.
