Japan Inflation Calculator
Historical purchasing power from 1868 to 2026 — 158 years of data
The Japanese yen was introduced during the Meiji Restoration in 1871, transforming Japan from feudal society to modern economy. From the pre-war gold standard to the devastating WWII inflation, through the post-war 'Japanese economic miracle' and the 'Lost Decades' of deflation, the yen tells a story unlike any other currency. See how purchasing power evolved across Japan's 155 years of modernity.

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.
What the Japan CPI data actually shows
Japan's monetary history breaks into two radically different halves. The first half, from 1871 to 1950, mirrors other countries: gold standard, world wars, hyperinflation. Prices rose something like 200-fold in Japan between 1940 and 1950. The second half is weirder and genuinely unique. After the 1989–90 asset bubble collapsed, Japan entered a three-decade period of deflation — not disinflation, actual falling prices — that no other modern economy has experienced. The yen's purchasing power between 1995 and 2020 was, for the first time anywhere since the 1890s, essentially flat. Even zero interest rates and rounds of quantitative easing couldn't generate inflation. Then, in 2022, Japan suddenly had 4% inflation alongside a collapsing currency, and economists who had spent careers explaining why Japan was stuck in deflation had to explain a new puzzle. The lesson most people take is that monetary rules that look permanent can suddenly stop working.
Japan's currency today
The yen is now near 150 per US dollar — a 32-year low as of 2026. The Bank of Japan has finally started raising rates from the near-zero levels that defined the previous thirty years. Japanese consumers are experiencing real inflation in imported goods for the first time since the 1980s, and domestic wages are slowly catching up. If this sticks, Japan may be leaving deflation for good, which would reshape household savings behavior that has persisted for a generation.
