What is the population of Japan?
The population of Japan (proper) is about 128 million, which is the figure from the census of 2010. However, a lower estimate of about 126.6 million was promulgated in 2012. This does not mean that the population decreased, but that different figures were used in the computation. The Japanese official monthly estimate for March 2013 was 127,360,000. That is about the average of the other figures.
