Japan Population Pyramid 2028
Japan in 2028
In 2028, Japan is projected to have a population of 121,024,348 people. That would be 4.6% less than in 2018 (126,913,433).
With a projected median age of 51.7 years, Japan would have a youth dependency ratio of 18.2 and an old-age dependency ratio of 52.1 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
