For example, if you started with ¥100, you would need to end with ¥110.71 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
When ¥100 is equivalent to ¥110.71 over time, that means that the "real value" of a single Japanese yen decreases over time. In other words, a yen will pay for fewer items at the store.
This effect explains how inflation erodes the value of a yen over time. By calculating the value in 2015 dollars, the chart below shows how ¥100 is worth less over 9 years.
According to the OECD and the World Bank, each of these JPY amounts below is equal in terms of what it could buy at the time:

Our calculations use the following inflation rate formula to calculate the change in value between 2015 and today:
Then plug in historical CPI values. The Japanese CPI was 100 in the year 2015 and 110.71358916166263 in 2024:
¥100 in 2015 has the same "purchasing power" or "buying power" as ¥110.71 in 2024.
To get the total inflation rate for the 9 years between 2015 and 2024, we use the following formula:
Plugging in the values to this equation, we get:
