Foundational Indicators
Historical Context
January 2026: 2.0%
December 2025: 2.4%
November 2025: 3.0%
October 2025: 2.9%
September 2025: 2.7%
June 2025: 3.7% (12-month high)
Methodology
Japan’s core inflation rate excludes fresh food prices and is calculated by the Statistics Bureau using the Consumer Price Index (CPI) basket. The YoY figure compares the current month’s index to the same month a year earlier, smoothing seasonal effects and one-off shocks.
Risk Balance
Upside: Yen depreciation, wage growth acceleration
Downside: Energy price declines, weak domestic demand
Chart Dynamics
January’s 2.0% reading marks a sharp drop from December’s 2.4% and sits well below the 12-month average of 3.1%. The pace of disinflation has accelerated since the summer peak, with the core rate falling by 1.7 percentage points since June 2025. Over the past six months, the trend has been consistently downward, reflecting easing energy costs and subdued consumer spending.
Compared to the 3.7% high in June 2025, the current level signals a return to pre-2022 inflation dynamics. The last time core inflation was this low was in June 2022, underscoring the scale of the recent moderation.
