Japan Consumer Price Index
Consumer Price Inflation, Monthly
Contributions to Headline Inflation
Each bar splits headline year-over-year inflation into the percentage-point contribution of the major expenditure groups; the line is headline CPI itself. The five largest current contributors are shown separately, the rest are bundled.
Major Expenditure Groups
Breadth of Price Increases
Computed over the individually priced items of the detailed-item table: the share whose price is up at least 2% on a year earlier, and the share falling. Broad inflation means most items rising, not a few large movers.
