JPY

The yen (円, en?) (sign: ¥; code: JPY) 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. As is common when counting in East Asia, large quantities of yen are often counted in multiples of 10,000 (man, 万) in the same way as values in Western countries are often quoted in thousands.

Etymology
The Japanese pronunciation is "en", the spelling and pronunciation "yen" is standard in English. This is due to a historical Portuguese transliteration which included the letter y based on romanization of an obsolete writing of the word which included the kana ゑ (ye/we). Similar examples of this romanization are found in such words as Yebisu, Iyeyasu, and Yedo, although the actual pronunciation was e.
