Japan Population Pyramid 2025
Japan in 2025
In 2025, Japan had a total population of 123,103,479 people. A decade earlier, in 2015, the population was still 127,275,872; it has declined by 3.3% since.
Half of the population was younger than 50.8 years; 11.2% were children under 15 and 30.0% were 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
