Per second-0.017people every second (counting down)
Per year-540,101the published annual figure
Japan ranks #43 of 217 countries for people (a net figure, so a world share is not meaningful here). At roughly -0.017 people per second, that is -1,479 in a day.
How this number is worked out
This is an honest projection, not a live register. Japan’s published annual figure is carried forward evenly over real elapsed time (peopleper second = the annual figure ÷ 31,556,952 seconds in a year). Each country’s NET population change so far — births and arrivals minus deaths and departures, projected from its annual growth rate. A few countries are shrinking; theirs counts down. The source is World Bank Open Data (CC-BY 4.0) (2024). The real total varies through the day and year; this is the running estimate, and we label it as one.
