Mount Fuji (富士山, Fuji-san^?, IPA: [ɸɯꜜdʑisaɴ] ( listen)) is the highest mountain in Japan located on Honshu Island at 3,776.24 m (12,389 ft). An active stratovolcano that last erupted in 1707–08, Mount Fuji lies about 100 kilometres (62 mi) south-west of Tokyo, and can be seen from there on a clear day. Mount Fuji's exceptionally symmetrical cone, which is snow-capped several months a year, is a well-known symbol of Japan and it is frequently depicted in art and photographs, as well as visited by sightseers and climbers. It is one of Japan's "Three Holy Mountains" (三霊山, Sanreizan^?) along with Mount Tate and Mount Haku.

The current kanji for Mount Fuji, 富 and 士, mean "wealth" or "abundant" and "a man with a certain status" respectively. However, these characters areateji, meaning that the characters were selected because their pronunciations match the syllables of the name but do not carry a meaning related to the mountain.

The origin of the name Fuji is unclear. A text of the 10th century Tale of the Bamboo Cutter says that the name came from "immortal" (不死, fushi, fuji^?) and also from the image of abundant (富, fu^?) soldiers (士, shi, ji^?) ascending the slopes of the mountain. An early folk etymology claims that Fuji came from 不二 (not + two), meaning without equal or nonpareil. Another claims that it came from 不尽 (not + to exhaust), meaning neverending.
