What the numbers say
In 2025, Japan's population in largest city fell 0.2% on 2024 (from 37.12 million to 37.04 million).
Across the 30 yearly changes before that (1995 to 2024), the average change was +0.4% and a typical year strayed about 0.3% from that (the standard deviation). This year's change was 1.8 standard deviations below that average, so it was larger than a typical year, though not out of the range seen before.
On record, the biggest yearly rise was 4% in 1964 and the biggest yearly fall was 0.2% in 2023. 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 39,389 a year. A straight line explains 70% of the movement over 10 observed years.

What this measures
Population in largest city is the urban population living in the country's largest metropolitan area.
Limitations: Aggregation of urban and rural population may not add up to total population because of different country coverage. There is no consistent and universally accepted standard for distinguishing urban from rural areas, in part because of the wide variety of situations across countries. Most countries use an urban classification related to the size or characteristics of settlements. Some define urban areas based on the presence of certain infrastructure and services. And other countries designate urban areas based on administrative arrangements.
