富士

Orthographic borrowing from Japanese 富士 (Fuji).

富士

1. (～山) Mount Fuji (a mountain, the highest mountain in Japan)
2. (～市) Fuji (a city in Shizuoka, Japan)
3. Fuji, a Japanese company

From Old Japanese, first attested in the Hitachi-no-kuni Fudoki (721 CE). The etymology continues to be debated, but there is wide acceptance of an origin from Ainu フヂ (fuji, “[goddess of] fire”), which is commonly associated with volcanoes by the Ainu people.[1]

Alexander Vovin (2017) proposes a derivation from 火 (pu, “fire”, Eastern Old Japanese term and hapax legomenon encountered only once in any ancient source,[2] inferred as equivalent to Western Old Japanese combining form ho and standalone form hi) +‎ 主 (nushi, “master”):[3]

*⟨pu nusi⟩ → */punusi/ → */punsi/ → /puzi/ (the form found in ancient texts like the Man'yōshū) → /fuʑi/

The current kanji spelling possibly relates to a folk etymology of 富 (fu, “abundant”) + 士 (shi, “soldiers”) climbing the mountain. Multiple other folk etymologies exist, such as 不死 (fushi, “immortal”). All the folk etymologies rely on on'yomi readings, a trait that Vovin finds unsatisfactory due to the reliance on Chinese morphemes to spell an ancient Japanese placename.
