What the numbers say about Kagoshima

Kagoshima covers 2.4% of the area of Japan and ranks 24th of 47 by population, against 10th by area.
It would take 42.2 prefectures the size of Kagoshima to cover Japan.
The largest, Hokkaido (Japan), is 8.90× the size of Kagoshima; the smallest, Kagawa, is 21% of it.
Closest in size within Japan: Yamagata (9,240 km², 1.04×) and Hyogo (8,380 km², 1.06×).
Counted as a country, Kagoshima would be larger than 70 of the 239 countries and territories listed on sizeversus, and would rank 170th by area, between Puerto Rico (9,010 km²) and French Southern and Antarctic Lands (6,990 km²).
With 1.6 million people it would rank 154th of 238 by population.
Kagoshima has 179 people per km², about the density of Uganda, which has 195 per km².
That makes Kagoshima the 32nd most densely populated of the 47 prefectures, 53% of the average for Japan (338 per km²).
On a standard web map (Web Mercator), a place at 31°N is drawn about 1.4× too large in area, so Kagoshima looks bigger there than it is.
Laid out flat, Kagoshima stretches about 570 km north to south and 273 km east to west.
Our measured 8,850 km² is 3.1% below Wikidata's official figure of 9,130 km². Official figures can include inland water or count land that an outline draws differently.
