mon — a unit of currency in pre-modern Japan
A common small unit of currency in Japan from the medieval period through the Edo period, used until the yen replaced it in 1871. A single mon was a trivial sum, so the word often appears in proverbs and set phrases meaning "a tiny amount of money."
An old currency unit, replaced by the 円 (yen) in 1871. It survives mainly in idioms that express "a tiny sum."
Common expressions
- 一文無し: penniless, without a single coin

- 早起きは三文の徳: the early bird gets the worm (lit. early rising is worth three mon)
