Japan’s national Consumer Price Index (CPI) rose 1.5% year-on-year in March 2026, according to data updated on 23 April 2026. The reading marks a modest acceleration from the previous annual rate of 1.3%, indicating a slight pickup in consumer price growth.
Both the current and previous readings are based on year-over-year comparisons, measuring price changes for March against the same month a year earlier. The latest figure suggests that inflationary pressures in Japan are firming, though still remaining at relatively moderate levels by international standards. Investors and policymakers will be watching upcoming data closely to assess whether this upward drift in prices gains further traction in the coming months.
