This chart is being prepared. Consumer Price Index (inflation) draws on Statistics Bureau of Japan, via e-Stat, which requires a free access key that is not yet configured. The explainer and source details below are final; the chart will appear once the data feed is connected.

What this shows

The Consumer Price Index (CPI) tracks the average price of a basket of goods and services that households buy. This chart shows three versions published by the Statistics Bureau: the headline “All items” index, “core” (excluding fresh food), and “core-core” (excluding fresh food and energy). All are set to 2020 = 100.

A key point for readers coming from the United States: in Japan, “core” means excluding fresh food only. The measure that also excludes energy is called “core-core” here.

How to read it: The index is set to 100 in the base year 2020. A value of 105 means prices in that basket are about 5% higher than the 2020 average.

Core CPI (Japan)
Japan reports three main inflation measures: "All items" (headline), "core" which removes fresh food (whose prices are volatile), and "core-core" which removes both fresh food and energy. The Bank of Japan watches core and core-core closely. Note this differs from the United States, where "core" already excludes both food and energy.
Core-core CPI
The "core-core" index strips out fresh food and energy to show underlying price trends that are less affected by volatile commodity and weather-driven prices. It is closest to what the US calls "core" inflation.
