Aosta Valley is 1.54× the size of Okinawa
Aosta Valley (region of Italy) covers about 3,300 km² (1,280 mi²) and Okinawa (prefecture of Japan) about 2,150 km² (829 mi²). Below, both outlines are drawn at one scale and centred on each other.

Okinawa: 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 fits
- Okinawa is 65% of the size of Aosta Valley.
- Aosta Valley is larger by 1,160 km² (446 mi²), which is 54% of the area of Okinawa.
- Measured in Belgiums: Aosta Valley is about 0.11, Okinawa about 0.07.
How they differ
- Aosta Valley is larger, but Okinawa has the larger population: 1.5 million against 126,000, 11.6× as many people.
- Per square kilometre that is 680 in Okinawa against 38 in Aosta Valley: Okinawa is 17.9× as densely populated.
- Their centres are about 9,980 km apart.
- A standard web map misstates the comparison: Aosta Valley at 46°N is drawn about 2.1× too large and Okinawa at 26°N about 1.2×, so the map shows Aosta Valley as 2.56× the size of Okinawa instead of 1.54×.
- Together Aosta Valley and Okinawa cover 5,450 km², close to the size of Cyprus (5,400 km², 1.0% smaller).
- The gap between them, 1,160 km², is about the size of São Tomé and Príncipe (1,040 km²).
- At Okinawa's density, Aosta Valley would have 2.2 million people (it has 126,000). At Aosta Valley's density, Okinawa would have 82,000 (it has 1.5 million).
- Aosta Valley's centre is 19.9° of latitude, about 2,210 km, farther north than Okinawa's.
- Aosta Valley is the 20th largest of the 20 regions of Italy and covers 1.1% of its area; it is the 20th most densely populated of them.
- Okinawa is the 45th largest of the 47 prefectures of Japan and covers 0.6% of its area; it is the 8th most densely populated of them.
- Aosta Valley lies about 20° of latitude (roughly 2,210 km) north of Okinawa.
- Shared out evenly, each person in Aosta Valley would have about 26,290 m² and each person in Okinawa about 1,470 m².
- Laid side by side, Aosta Valley and Okinawa would cover 5,450 km², about the same size as Cyprus.
- Together they have 1.6 million people, 1.13× as many people as East Timor.
- Okinawa is drawn from 133 points: at a size under 2,500 km² the outline is a sketch, so the overlap shows the proportions rather than the exact shape.

- Wikidata's official figure of 3,260 km² agrees with our measured area of 3,300 km², to within 2%.
- 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.

Sources and method
- Outlines
- Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
- Boundary
- De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
