FX.co ★ Japan's Consumer Prices Dip as CPI Declines in September

Japan's Consumer Price Index (CPI), not seasonally adjusted, witnessed a slight decline in September 2025, recording a -0.1% change from the previous month, according to updated data released on October 23, 2025. This marks a shift from August's figure, where the CPI had seen a rise of 0.2%.

The month-over-month comparison shows a reversal in inflationary trends, suggesting a slowdown in consumer price growth. Economic analysts are keenly observing these fluctuations, as CPI is a key indicator of inflation and purchasing power within the economy.

This recent decrease may prompt policymakers and economists to reassess their expectations and strategies in efforts to stabilize the economy, particularly as it recovers and adjusts post-pandemic influences. Observers are now anticipating potential measures that may be introduced to counteract these deflationary pressures in order to maintain economic stability.
