Japan's National Core Consumer Price Index (CPI) experienced a slight increase in September 2025, rising to 2.9% from 2.7% in August. This uptick was observed after comparing the inflation rate year-over-year, meaning the September data is juxtaposed with the same month in the previous year. The updated data was made accessible on October 23, 2025.

The rise in the National Core CPI, which excludes volatile items like fresh food, indicates a modest wave of inflation pressure within Japan. Policymakers and economists will be carefully analyzing these figures as they adapt monetary policies to balance inflation moderation with economic stability.

The subtle increase points to ongoing inflationary trends, an outcome that may reflect broader economic factors such as global supply chain constraints or shifts in domestic demand. As Japan continues its post-pandemic economic rebound, stakeholders will be closely monitoring these key indicators to guide future economic strategies.
