What is the currency used in Japan?

The currency used in Japan is the Yen. The Yen is the official currency of Japan and is represented by the symbol "¥" and the currency code "JPY." It has been in use since the late 19th century and is one of the most traded currencies in the world. The Yen is known for its stability and is a key player in global markets, often serving as a safe haven during times of economic uncertainty.

Other options do not represent Japan's currency. The Dollar is the currency of the United States and several other countries, the Won is the currency of South Korea, and the Euro is used by many European countries, but none of these apply to Japan.
