Coins of the Japanese Empire (1868-1947)
In 1870, the Japanese Empire carried out a monetary reform, the result of which was the introduction of the yen as a national currency to replace the Tokugawa monetary system that had existed since 1603. The name of the yen currency itself came from China and is called "yuan" in Chinese. The fractional derivatives of yen were rin - 1⁄1000 yen and sen - 1⁄100 yen.
