History of Japan's currency

The yen replaced the complex Tokugawa monetary system in 1871. It was linked to silver, then gold. WWII caused hyperinflation — prices rose over 200× between 1944 and 1950. The post-war yen was pegged at 360 per US dollar until 1971, underpinning Japan's export-driven miracle economy. Since 1990, Japan has faced persistent deflation and near-zero interest rates — a unique case study in modern monetary economics.
