How they differ
- Osaka also has the larger population: 8.8 million against 902,000, 9.78× as many people.
- Per square kilometre that is 4,758 in Osaka against 540 in Comoros: Osaka is 8.82× as densely populated.
- Their centres are about 10,900 km apart.
- A standard web map misstates the comparison: Osaka at 35°N is drawn about 1.5× too large and Comoros at 12°S about 1.0×, so the map shows Osaka as 1.57× the size of Comoros instead of 1.11×.
- Together Osaka and Comoros cover 3,530 km², close to the size of Turkish Republic of Northern Cyprus (3,320 km², 5.9% smaller).
- The gap between them, 183 km², is about the size of Aruba (170 km²).
- At Comoros's density, Osaka would have 1.0 million people (it has 8.8 million). At Osaka's density, Comoros would have 8.0 million (it has 902,000).

- Laid side by side, Osaka and Comoros would cover 3,530 km², 90% of the size of Cape Verde.
- Together they have 9.7 million people, about as many people as Hungary.
- Osaka is drawn from 55 points and Comoros is drawn from 64 points: at sizes under 2,500 km² the outlines are a sketch, so the overlap shows the proportions rather than the exact shape.
- Counted as a country, Osaka would rank 182nd by area and 100th by population.

Sources and method
- Outlines
- Natural Earth, 1:10m Admin 1 - States, Provinces, public domain for the region; Natural Earth, 1:10m Admin 0 - Countries, 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.
