The yen (Japanese 円) is the currency of Japan. It is the third most-traded currency in the foreign exchange market after the United States dollar and the euro. It is also widely used as a reserve currency after the U.S. dollar, the euro and the pound sterling. The ISO 4217 codes for the yen are JPY and 392. The romanised symbol is ¥ while in Japanese it is also written with the kanji 円. While not a usage specific to currency, large quantities of yen are often counted in multiples of 10,000 (man, 万) in the same way as values in the United States are often quoted or rounded off to hundreds or thousands.
