¥530.21
in 2020

According to the World Bank consumer price index for Japan, today's prices in 2020 are 430.21% higher than average prices since 1961. This means that a yen today only buys 18.86% of what it could buy in 1961. The Japanese Yen experienced an average inflation rate of 2.87% per year during this period, causing the real value of a yen to decrease.

In other words, ¥100 in 1961 is equivalent in purchasing power to about ¥530.21 in 2020, a difference of ¥430.21 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 year-over-year inflation rate (2019 to 2020) is now 0.48%^{1}.
If this number holds, ¥100 today will be equivalent in buying power to ¥100.48 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 ¥530.21 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When ¥100 is equivalent to ¥530.21 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 is worth less over 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:
