What fits

Japan is 80% of the size of Cameroon.
Cameroon is larger by 90,800 km² (35,100 mi²), which is 24% of the area of Japan.
Measured in Belgiums: Cameroon is about 15.1, Japan about 12.2.

How they differ

Cameroon is larger, but Japan has the larger population: 123.8 million against 28.4 million, 4.36× as many people.
Per square kilometre that is 331 in Japan against 61 in Cameroon: Japan is 5.42× as densely populated.
Their centres are about 12,600 km apart.
On a standard web map Japan looks larger than Cameroon: Cameroon at 6°N is drawn about 1.0× too large and Japan at 37°N about 1.6×, so the map shows Japan as 1.26× the size of Cameroon, when Cameroon is 1.24× the size of Japan.
Together Cameroon and Japan cover 838,000 km², close to the size of Namibia (823,000 km², 1.8% smaller).
The gap between them, 90,800 km², is about the size of Western Sahara (90,500 km²).
At Japan's density, Cameroon would have 153.9 million people (it has 28.4 million). At Cameroon's density, Japan would have 22.8 million (it has 123.8 million).
Japan's centre is 31.7° of latitude, about 3,530 km, farther north than Cameroon's.

Population: Wikidata 2023 and Wikidata 2024, covering each whole country. Official figures: Wikidata (CC0).

Our measured 464,000 km² is 2.3% below Wikidata's official figure of 475,000 km². Official figures can include inland water or count land that an outline draws differently.
Wikidata's official figure of 378,000 km² agrees with our measured area of 374,000 km², to within 2%.

Sources and method

Outlines: Natural Earth, 1:10m Admin 0 - Countries, public domain
Boundary: De facto, as drawn by Natural Earth. Main territory: the largest landmass and every part within 1,000 km of it.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded. Comparisons use main-territory area.
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.
