Demographic profile

Japan is the 12th most populous of the 238 countries and territories tracked on this site, home to about 1.46% of everyone alive. Within Eastern Asia, it ranks 2 of 8.

Each day brings roughly 2,004 births and 4,310 deaths — a net decline of about 842,249 people a year. At -0.69% annually, the population would halve in roughly 101 years if the trend held. Real trajectories bend as fertility, mortality and migration shift, which is why the chart below shows both history and projection.

Among its first-level divisions, the largest by our modelled allocation is Okinawa, holding an estimated 17.3% of the national population. The full breakdown of all 47 states and regions is in the table below — regional figures outside Sudan are modelled estimates built on real region names, and are flagged as such.

Literacy stands near 99.0% and adult smoking prevalence around 20.1%, with life expectancy at about 80.7 years. Baselines come from UN World Population Prospects, the World Bank, WHO surveys, WorldPop and HDX; the counters project them forward in real time — the method, and every caveat, is documented on our data sources page.
