Japan Inflation & Purchasing Power Calculator
The 1920s were a decade of extremes. In the United States, the "Roaring Twenties" saw unprecedented consumer prosperity — the first mass market for cars, radios and household appliances. Real wages rose significantly and credit became widely available for the first time. Yet in Germany, 1923 brought the most dramatic hyperinflation in modern history: a loaf of bread cost 200 billion marks at its peak. A wheelbarrow of cash couldn't buy a newspaper. This destroyed the life savings of an entire generation and permanently shaped German attitudes toward inflation and monetary stability.
At the height of German hyperinflation in November 1923, the exchange rate was 4.2 trillion marks to 1 US dollar. Workers were paid twice daily so they could spend wages before they lost their value.
The CPI comparison estimates the purchasing power of ¥1,000 in 1929 Japan. No wage comparison is shown for this amount and year: same-year wage data may be missing, or the comparison is smaller than half a week. We do not infer a salary, rent period or social class from the nominal amount alone.
1929 began with the decade's last great bull market. The Wall Street Crash of October ended it. By year's end the US economy was sliding into what would become the Great Depression, and the rest of the world soon followed. It was the most consequential economic year of the 20th century.
¥1000 in 1929 is equivalent to approximately ¥21,507 in 2026. This represents a 2051% increase due to cumulative inflation in Japan between 1929 and 2026.
Since 1929, the Japan currency has lost approximately 95% of its purchasing power. In other words, what cost ¥1000 in 1929 would cost ¥21,507 today — you need 21.5× more money to buy the same goods.
No wage comparison is shown for this amount and year. We only use data recorded for the requested year, and omit comparisons smaller than half a week. Wage data is separate from CPI and remains a legacy estimate.
1929: CPI ≈ 73, linearly interpolated between 1920 and 1950. No annual observation for 1929 is loaded in our dataset; official data may exist elsewhere. The endpoints may include unverified estimates. 2026: CPI 1570, an unverified estimate in the legacy dataset, not a verified official annual observation.
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. ¥1000 in 1929 bought a specific number of loaves of bread, weeks of rent, or months of wages — context that makes the number real and tangible, not just an abstract percentage.
