To find the decline in Japan's population between 2012 and 2021, we can subtract the population in 2021 from the population in 2012:
Population in 2012: 127.52 million
Population in 2021: 125.3 million
Decline = Population in 2012 - Population in 2021
Decline = 127.52 million - 125.3 million
Decline = 2.22 million
Japan's population declined by 2.22 million people between 2012 and 2021.
Population in 2012: 127.52 million
Population in 2021: 125.3 million
Decline = Population in 2012 - Population in 2021
Decline = 127.52 million - 125.3 million
Decline = 2.22 million
Japan's population declined by 2.22 million people between 2012 and 2021.

To calculate the percentage decline in Japan's population from 2012 to 2021, we can use the following formula:
\[
\text{Percentage Decline} = \left(\frac{\text{Decline}}{\text{Original Population}}\right) \times 100
\]
Where:
- Decline = 2.22 million
- Original Population (2012) = 127.52 million
Substituting the values:
\[
\text{Percentage Decline} = \left(\frac{2.22}{127.52}\right) \times 100 \approx 1.74\%
\]
Therefore, Japan's population declined by approximately **1.74%** between 2012 and 2021.
\[
\text{Percentage Decline} = \left(\frac{\text{Decline}}{\text{Original Population}}\right) \times 100
\]
Where:
- Decline = 2.22 million
- Original Population (2012) = 127.52 million
Substituting the values:
\[
\text{Percentage Decline} = \left(\frac{2.22}{127.52}\right) \times 100 \approx 1.74\%

Therefore, Japan's population declined by approximately **1.74%** between 2012 and 2021.
