Hokkaido (Japan): Part of this region's boundary is disputed with Russia. 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

Hokkaido (Japan) is 95% of the size of French Guiana.
French Guiana is larger by 4,400 km² (1,700 mi²), which is 5.6% of the area of Hokkaido (Japan).
Measured in Belgiums: French Guiana is about 2.71, Hokkaido (Japan) about 2.57.

How they differ

French Guiana is larger, but Hokkaido (Japan) has the larger population: 5.4 million against 288,000, 18.8× as many people.
Per square kilometre that is 69 in Hokkaido (Japan) against 3.5 in French Guiana: Hokkaido (Japan) is 19.9× as densely populated.
Their centres are about 14,500 km apart.
On a standard web map Hokkaido (Japan) looks larger than French Guiana: French Guiana at 4°N is drawn about 1.0× too large and Hokkaido (Japan) at 43°N about 1.9×, so the map shows Hokkaido (Japan) as 1.78× the size of French Guiana, when French Guiana is 1.06× the size of Hokkaido (Japan).
Together French Guiana and Hokkaido (Japan) cover 162,000 km², close to the size of Somaliland (167,000 km², 3.4% bigger).
The gap between them, 4,400 km², is about the size of Cape Verde (3,930 km²).
At Hokkaido (Japan)'s density, French Guiana would have 5.7 million people (it has 288,000). At French Guiana's density, Hokkaido (Japan) would have 273,000 (it has 5.4 million).
Hokkaido (Japan)'s centre is 39.5° of latitude, about 4,390 km, farther north than French Guiana's.
French Guiana is the 2nd largest of the 18 regions of France and covers 13% of its area; it is the 18th most densely populated of them.
Hokkaido (Japan) is the largest of the 47 prefectures of Japan and covers 21% of its area; it is the 47th most densely populated of them.
Hokkaido (Japan) lies about 39° of latitude (roughly 4,390 km) north of French Guiana.
Shared out evenly, each person in French Guiana would have about 288,450 m² and each person in Hokkaido (Japan) about 14,500 m².
Laid side by side, French Guiana and Hokkaido (Japan) would cover 162,000 km², 1.03× the size of Tunisia.
Together they have 5.7 million people, about as many people as Finland.

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.
