What is the highest mountain in Japan?

It is the famous Mt. Fuji, which is 3,776 meters high.
It can in no way be compared with the world's highest peaks such as Mt. Everest (Chomolungma, 8,848 meters) in terms of height.
However, it has become emblematic of Japan with the striking beauty of its nearly perfect conical profile and wide-flowing skirt.
At the peak of this dormant volcano there is a crater, 800 meters across and 200 meters deep. From ancient times, Mt. Fuji has been an object of worship as a sacred mountain, and its perfection has long been celebrated in traditional verses such as haiku and tanka.
The five Fuji lakes at the foot of the mountain were formed from runoff from Mt. Fuji and serve as popular tourist spots throughout the four seasons.
Many renowned　artists　have　taken　up　the　challenge　to depict Mt. Fuji.
Among them, Katsushika Hokusai, an ukiyo-e woodblock print artist of the Edo period (1603－1868),won great acclaim for his Fugaku Sanju-rokkei (36 scenes of Mt. Fuji), in which he painted Mt. Fuji from various perspectives at various hours of the day in each season.
However, Mt. Fuji is facing a serious problem.
Landslides on the western side, known as Osawa, are changing the picture perfect shape of the mountain.
