The Yen ¥, code: JPY, is the official currency of Japan with two subdivisions, the Sen (1/100) and the Rin (1/1000).

The Japanese yen was introduced in 1871 during the Meiji era to modernize the Japanese economy. After a period of stability and rapid growth, the yen experienced devaluations during the World Wars. Following World War II, Japan thrived economically, but the 1980s saw a strong appreciation of the yen, impacting exporters. The 1990s were marked by economic challenges, followed by monetary policies to stimulate the economy. The yen remains subject to fluctuations influenced by global and domestic economic factors, reflecting the intricate evolution of the Japanese economy over time.
