Mt. Fuji Climbing Experience
It is the highest peaked volcano in Japan, where tourists and locals regularly climb here to observe (more than 200,000 people per year, to be exact), called one of the three Holy Mountains (3 holy mountains in Japan including Mount Fuji, Mount Haku and Mount Tate). The last eruption of Mount Fuji occurred in 1707, and the ash spread as far as Tokyo, forming a new crater on the eastern flank. From July to September is the official climbing season, trails and climbing facilities are again open to visitors. The most popular way to climb this volcano is to climb halfway to rest in the huts, set off again in the night, and reach the summit to watch the sunrise. Sun worship at the top of a mountain is a form of spirituality, regardless of whether you are religious or not. You can't avoid the crowds here, with some even claiming that climbing between multiple like-minded people adds to the overall experience.
