Acre is 1.95× the size of Hokkaido (Japan)

Acre (state of Brazil) covers about 154,000 km² (59,500 mi²) and Hokkaido (Japan) (prefecture of Japan) about 78,800 km² (30,400 mi²). Below, both outlines are drawn at one scale and centred on each other.

Acre
Hokkaido (Japan)

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 51% of the size of Acre.
Acre is larger by 75,200 km² (29,000 mi²), which is 95% of the area of Hokkaido (Japan).
Measured in Belgiums: Acre is about 5.02, Hokkaido (Japan) about 2.57.

How they differ

Acre is larger, but Hokkaido (Japan) has the larger population: 5.4 million against 830,000, 6.54× as many people.
Per square kilometre that is 69 in Hokkaido (Japan) against 5.4 in Acre: Hokkaido (Japan) is 12.8× as densely populated.
Their centres are about 15,100 km apart.
A standard web map misstates the comparison: Acre at 9°S is drawn about 1.0× too large and Hokkaido (Japan) at 43°N about 1.9×, so the map shows Acre as 1.06× the size of Hokkaido (Japan) instead of 1.95×.
Together Acre and Hokkaido (Japan) cover 233,000 km², close to the size of Romania (236,000 km², 1.5% bigger).
The gap between them, 75,200 km², is about the size of Panama (74,500 km²).
At Hokkaido (Japan)'s density, Acre would have 10.6 million people (it has 830,000). At Acre's density, Hokkaido (Japan) would have 425,000 (it has 5.4 million).
Hokkaido (Japan)'s centre is 52.7° of latitude, about 5,860 km, farther north than Acre's.
Acre is the 16th largest of the 27 states and districts of Brazil and covers 1.8% of its area; it is the 23rd 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 53° of latitude (roughly 5,860 km) north of Acre, on the other side of the equator.
Shared out evenly, each person in Acre would have about 185,540 m² and each person in Hokkaido (Japan) about 14,500 m².
Laid side by side, Acre and Hokkaido (Japan) would cover 233,000 km², about the same size as Romania.
Together they have 6.3 million people, about as many people as the Republic of the Congo.

Wikidata's official figure of 153,000 km² agrees with our measured area of 154,000 km², to within 2%.
Our measured 78,800 km² is 5.6% below Wikidata's official figure of 83,400 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.
