Japan Inflation & Purchasing Power Calculator
World War I (1914–1918) shattered the stable monetary world of the gold standard era. Governments printed enormous quantities of money to finance the war, causing rapid inflation across all major economies. In the United Kingdom, prices doubled between 1914 and 1920. The US Federal Reserve, established in 1913, began its role as the guardian of monetary policy. For ordinary families, the purchasing power of their savings was dramatically eroded — a pound or dollar saved in 1914 bought significantly less by 1918.
Germany's war spending was so extreme that by 1918 the German mark had lost over 50% of its pre-war purchasing power — a preview of the catastrophic hyperinflation coming in 1923.
The CPI comparison estimates the purchasing power of ¥150 in 1910 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.
¥150 in 1910 is equivalent to approximately ¥36,797 in 2026. This represents a 24431% increase due to cumulative inflation in Japan between 1910 and 2026.
Since 1910, the Japan currency has lost approximately 100% of its purchasing power. In other words, what cost ¥150 in 1910 would cost ¥36,797 today — you need 245.3× 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.
1910: CPI ≈ 6.4, linearly interpolated between 1900 and 1920. No annual observation for 1910 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. ¥150 in 1910 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.
