Mount Fuji (富士山, Fujisan) is with 3776 meters Japan's highest mountain. It is not surprising that the nearly perfectly shaped volcano has been worshiped as a sacred mountain and experienced big popularity among artists and common people throughout the centuries.
Mount Fuji is an active volcano, which most recently erupted in 1708. It stands on the border between Yamanashi andShizuoka Prefectures and can be seen from Tokyo and Yokohama on clear days.
Another easy way to view Mount Fuji is from the train on a trip between Tokyo and Osaka. If you take the shinkansen from Tokyo in direction of Nagoya, Kyoto and Osaka, the best view of the mountain can be enjoyed from around "Shin-Fuji Station" on the right hand side of the train, about 40-45 minutes into the journey.
Note however, that clouds and poor visibility often block the view of Mount Fuji, and you have to consider yourself lucky if you get a clear view of the mountain. Visibility tends to be better during the colder seasons of the year than in summer, and in the early morning and late evening hours than during the middle of the day.
