Prefecture of Japan
Okinawa
沖縄県Okinawa is a prefecture of Japan. It covers about 2,150 km² (829 mi²), the 45th largest of the 47 prefectures in Natural Earth’s file for Japan, and 1.07× the size of Mauritius. About 1.5 million people live there (Wikidata, 2021).
Part of this region's boundary is disputed with China and Taiwan. Size Versus draws Natural Earth's de facto outline, the boundary as it is held on the ground, and takes no position on it.

What the numbers say about Okinawa
- Okinawa covers 0.6% of the area of Japan and ranks 25th of 47 by population, against 45th by area.
- It would take 174 prefectures the size of Okinawa to cover Japan.
- The largest, Hokkaido (Japan), is 36.7× the size of Okinawa; the smallest, Kagawa, is 86% of it.
- Closest in size within Japan: Tokyo (2,180 km², 1.02×) and Kanagawa (2,380 km², 1.11×).
- Counted as a country, Okinawa 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 1.5 million people it would rank 155th of 238 by population.
- Okinawa has 680 people per km², about the density of Mauritius, which has 628 per km².
- That makes Okinawa the 8th most densely populated of the 47 prefectures, 2.01× the average for Japan (338 per km²).
- On a standard web map (Web Mercator), a place at 26°N is drawn about 1.2× too large in area, so Okinawa looks bigger there than it is.
- Laid out flat, Okinawa stretches about 399 km north to south and 843 km east to west.
- Our measured 2,150 km² is 5.8% below Wikidata's official figure of 2,280 km². Official figures can include inland water or count land that an outline draws differently. This difference is flagged for review.
- Okinawa is small enough that Natural Earth draws it from only 133 points. Take its shape as a sketch and the official figure as the firmer number.
- Natural Earth draws the Amami Islands, 1,150 km² in 6 pieces, as part of Okinawa. They belong to Kagoshima, and this outline leaves them out.

- Boundary
- De facto, as drawn by Natural Earth. Part of this boundary is disputed; Size Versus takes no position on it.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outline, shown rounded. The region’s whole area is counted, every island included.
- Official figures
- Area, population and capital from Wikidata (CC0), fetched 2026-11-12
- Population
- Wikidata, 2021. Japan’s units share the 2021 figures where Wikidata has them; the year is shown wherever the figure is.
- Matching
- Countries come from Natural Earth’s country file. Places whose status is contested and dependencies are never used as automatic matches. A region under 2,500 km² is matched against the small countries and island nations.
