What the numbers say
In 2025, Japan's population ages 15-64, female fell 0.5% on 2024 (from 35.91 million to 35.73 million).
Across the 30 yearly changes before that (1995 to 2024), the average change was −0.6% and a typical year strayed about 0.4% from that (the standard deviation). This year's change was 0.4 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 2.5% in 1963 and the biggest yearly fall was 1.5% in 2013. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2016 to 2025 the straight-line trend is downward, about 188,456 a year. A straight line explains 99% of the movement over 10 observed years.
