The yen is Japan’s official currency, introduced by the Meiji government in 1871.
The Japanese word en means “round,” referring to the shape of coins, and the currency symbol is ¥. The yen replaced a complex feudal coin system as Japan modernized its finances after the Meiji Restoration. Japan’s central bank, the Bank of Japan, issues banknotes, while the Ministry of Finance authorizes coins.
Modern Japanese notes feature historical figures including educator Fukuzawa Yukichi on the 10,000-yen note, although a redesigned series began entering circulation in 2024. Coins range from 1 yen to 500 yen, with newer 500-yen versions using multiple metals and security features.
The yen is one of the world’s major reserve and trading currencies. It is distinct from South Korea’s won and China’s renminbi, despite all three economies being in East Asia.
