What the numbers say about Tokyo
- Tokyo covers 0.6% of the area of Japan and ranks 1st of 47 by population, against 44th by area.
- It would take 171 prefectures the size of Tokyo to cover Japan.
- The largest, Hokkaido (Japan), is 36.1× the size of Tokyo; the smallest, Kagawa, is 85% of it.
- Closest in size within Japan: Okinawa (2,150 km², 1.02×) and Kanagawa (2,380 km², 1.09×).
- Counted as a country, Tokyo 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 14.3 million people it would rank 76th of 238 by population.
- Tokyo has 6,534 people per km².
- That makes Tokyo the most densely populated of the 47 prefectures, 19.3× the average for Japan (338 per km²).
- Tokyo has 94.8× the density of Hokkaido (Japan), the least crowded of the 47: 6,534 against 69 people per km².
- Wikidata holds no 2021 figure for Tokyo; the 2022 figure is the only one it has, so Tokyo 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 Tokyo looks bigger there than it is.
- Laid out flat, Tokyo stretches about 1,290 km north to south and 1,520 km east to west.
- Wikidata's official figure of 2,190 km² agrees with our measured area of 2,180 km², to within 2%.
- Tokyo is small enough that Natural Earth draws it from only 173 points. Take its shape as a sketch and the official figure as the firmer number.
