Mount Fuji (Japanese 富士山 Fujisan) is a volcano located near Tokyo. At the top, there is snow for most of the year. It is an international symbol of Japan and of Tokyo.
In Monsters, Inc., Mount Fuji appears outside a window when Mike and Sulley run through a Japanese building while being chased by Randall.
In Cars 2, it first appears in the background when the camera shows Tokyo from the air as night time comes. It also appears at the start of the introduction of the World Grand Prix.
