円（えん、en）
- japanese yen

The Japanese word 円 (えん, en) has two primary meanings: It represents the Japanese currency, "yen," and it can also mean "circle" or "round." The context determines the correct meaning. When referring to money, it is usually written with the kanji 円. When referring to a circle, it can also be written with the kanji 円, but is often written in hiragana えん. The currency is divided into smaller units called sen and rin, although these are rarely used nowadays. The value of the 円 is determined by the global economy and fluctuates against other currencies.

The kanji 円 is originally derived from the Chinese character 圓 (yuán) and was adopted into Japanese. Its original meaning in Chinese also encompasses both "circle" and, by extension, a unit of money (due to the round shape of ancient coins). The use of 円 for the Japanese currency was officially adopted in the Meiji era (1868-1912).
