How they differ
- Montana is larger, but Japan has the larger population: 123.8 million against 1.1 million, 114× as many people.
- Per square kilometre that is 331 in Japan against 2.9 in Montana: Japan is 116× as densely populated.
- Their centres are about 8,490 km apart.
- A standard web map misstates the comparison: Montana at 47°N is drawn about 2.2× too large and Japan at 37°N about 1.6×, so the map shows Montana as 1.38× the size of Japan instead of 1.02×.
- Together Montana and Japan cover 753,000 km², close to the size of Zambia (752,000 km², 0.1% smaller).
- The gap between them, 5,990 km², is about the size of Palestine (6,070 km²).
- At Japan's density, Montana would have 125.8 million people (it has 1.1 million). At Montana's density, Japan would have 1.1 million (it has 123.8 million).
- Montana's centre is 9.6° of latitude, about 1,070 km, farther north than Japan's.
- Montana is the 4th largest of the 51 states and districts of the United States and covers 4.0% of its area; it is the 49th most densely populated of them.
- Japan ranks 64th of 246 countries and territories by area.
- Montana lies about 10° of latitude (roughly 1,070 km) north of Japan.
- Shared out evenly, each person in Montana would have about 350,010 m² and each person in Japan about 3,020 m².
- Laid side by side, Montana and Japan would cover 753,000 km², about the same size as Zambia.
- Together they have 124.9 million people, about as many people as Ethiopia.
- Counted as a country, Montana would rank 63rd by area and 162nd 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.
