The currency used in Japan is the yen (JPY). The yen was introduced in 1871 and is one of the most traded currencies in the world. Symbolized by the character "¥", it is issued by the Bank of Japan, the country's central bank. The yen is significant not only for domestic trade but also as a major reserve currency globally, reflecting Japan's economic status. Banknotes are issued in denominations of 1,000, 2,000, 5,000, and 10,000 yen, while coins are available in 1, 5, 10, 50, 100, and 500 yen.
