Japan

Like every city on this site, Numazu is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 137 cities in Japan in 2025, and a dot's area is how many people live there, the biggest being Tokyo. The ringed dot in colour is Numazu; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Numazu covered 110 km², and buildings, roads and other built-up land covered 29 km² of it. That is 78 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 32%, and its people are about as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Japan
Its share of Japan
Of every 1,000 people in Japan in 2025, 3 lived in Numazu, which is 374,507 people.
How to read this: 1,000 squares stand for everyone in Japan, one square for every 1,000th person. Count the coloured ones and you have Numazu's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Numazu are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Numazu publishes about itself: how the figures here are put together.
