Tips

1. August is the peak season of mountaineering on Mt. Fuji as the rainy season is over. But the trails might also be closed temporarily in the bad weather of heavy rain or gales. Mountaineers are advised to watch the local weather forecast and prepare linen gloves, alpenstock, raincoat, drinking water, some food, and more.
