According to the World Bank consumer price index for Japan, today's prices in 2020 are 435.53% higher than average prices since 1961. The Japanese Yen experienced an average inflation rate of 2.89% per year during this period, meaning the real value of a yen decreased.

In other words, ¥100 in 1961 is equivalent in purchasing power to about ¥535.53 in 2020, a difference of ¥435.53 over 59 years. This inflation data is collected by the World Bank and is specific to Japan.

The 1961 inflation rate was 5.37%. The current inflation rate (2019 to 2020) is now 0.98%^{1}. If this number holds, ¥100 today will be equivalent in buying power to ¥100.98 next year.

This chart shows a calculation of buying power equivalence for ¥100 in 1961 (price index tracking began in 1960).

For example, if you started with ¥100, you would need to end with ¥535.53 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When ¥100 is equivalent to ¥535.53 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 1961 dollars, the chart below shows how ¥100 buys less over the past 59 years.

According to the World Bank, each of these JPY amounts below is equal in terms of what it could buy at the time:
