What is the Japanese inflation based on CPI?
When we talk about the rate of inflation in Japan, this often refers to the rate of inflation based on the consumer price index, or CPI for short. The Japanese CPI shows the change in prices of a standard package of goods and services which Japanese households purchase for consumption.
In order to measure Japanese inflation, an assessment is made of how much the Japanese CPI has risen in percentage terms over a give period compared to the CPI in Japan in a preceding period. If prices have fallen this is called deflation (negative inflation).
