Japan’s core consumer price index (CPI) rose to 2.5% year-over-year, up from the previous reading of 2.2%, according to data updated on 28 April 2026. The increase indicates that underlying inflationary pressures in the country remain elevated compared with a year earlier.
The latest figure reflects the change in core prices for the most recent month versus the same month in the prior year, while the previous 2.2% reading was measured on the same year-over-year basis for the preceding month. The uptick suggests that price growth is not only persisting but has slightly accelerated, which is closely watched in the context of the Bank of Japan’s efforts to assess the durability of inflation trends.
This steady rise in core CPI is likely to be a key input for policymakers and market participants evaluating the trajectory of Japan’s price dynamics and the potential implications for future monetary policy decisions.
