In 2005, Japan's population declined for the first time, two years earlier than predicted. High sanitary and health standards and a diet of fish and rice produce a life expectancy exceeding that of the United States. | + | Japan's population, currently 125 million, has experienced a phenomenal growth rate during the past 100 years as a result of scientific, industrial, and sociological changes, but this has ended because of falling birth rates and a lack of immigration.

However, the population of Japan is expected to fall to only 107 million in 2050, and by 2100, it would be down to 75 million, falling below the United Kingdom. |
