The weather on Mount Fuji often doesn't follow forecasts precisely and can change abruptly. Especially during the summer when many people climb, even if the weather on the plains seems calm, on Mount Fuji there can be strong winds, thunderstorms, and sometimes even snow or hail. Therefore, it's crucial for your safety and peace of mind to collect the latest weather information from smartphones, trailheads, mountain huts, and other sources before climbing Mount Fuji.

During mid-summer when everyone climbs Mount Fuji, even if temperatures exceed 30°C in lowlands, at the 5th Station (at 2,400 meters), it's around 15°C, and at the summit, it's about 5°C. Particularly at night or early morning, it can feel as cold as winter, and with strong winds, wind chill can make it feel even colder, potentially below freezing. In such conditions, if your clothing gets wet, hypothermia, a very dangerous condition, can occur. Therefore, regardless of weather forecasts, it's essential to always prepare with rain gear, spare clothing, and other necessary items when climbing Mt. Fuji.
