The national currency of Japan is the yen. The symbol for the yen is ¥, and it is one of the most traded currencies in the world. The yen has a significant influence on global financial markets, especially as Japan is one of the largest economies. The currency was first introduced in 1871 during the Meiji period and replaced the previous complex monetary system. The Bank of Japan regulates the issuance and value of the yen, and it plays a crucial role in Japan’s economic policies. Currency exchange rates can impact international trade heavily, particularly in the technology and automotive sectors.
