What the numbers say about Kanagawa
- Kanagawa covers 0.6% of the area of Japan and ranks 2nd of 47 by population, against 43rd by area.
- It would take 157 prefectures the size of Kanagawa to cover Japan.
- The largest, Hokkaido (Japan), is 33.0× the size of Kanagawa; the smallest, Kagawa, is 78% of it.
- Closest in size within Japan: Saga (2,450 km², 1.03×) and Tokyo (2,180 km², 1.09×).
- Counted as a country, Kanagawa would be larger than 59 of the 239 countries and territories listed on sizeversus, and would rank 181st by area, between Luxembourg (2,610 km²) and Mauritius (2,000 km²).
- With 9.2 million people it would rank 96th of 238 by population.
- Kanagawa has 3,865 people per km².
- That makes Kanagawa the 3rd most densely populated of the 47 prefectures, 11.4× the average for Japan (338 per km²).
- Wikidata holds no 2021 figure for Kanagawa; the 2020 figure is the only one it has, so Kanagawa is not counted the same way as the 38 prefectures that carry 2021.
- On a standard web map (Web Mercator), a place at 35°N is drawn about 1.5× too large in area, so Kanagawa looks bigger there than it is.
- Laid out flat, Kanagawa stretches about 60 km north to south and 80 km east to west.
- Wikidata's official figure of 2,420 km² agrees with our measured area of 2,380 km², to within 2%.
- Kanagawa is small enough that Natural Earth draws it from only 83 points. Take its shape as a sketch and the official figure as the firmer number.
