What fits

Japan is 56% of the size of Myanmar.
Myanmar is larger by 290,000 km² (112,000 mi²), which is 78% of the area of Japan.
Measured in Belgiums: Myanmar is about 21.6, Japan about 12.2.

How they differ

Myanmar is larger, but Japan has the larger population: 123.8 million against 53.4 million, 2.32× as many people.
Per square kilometre that is 331 in Japan against 80 in Myanmar: Japan is 4.12× as densely populated.
Their centres are about 4,340 km apart.
A standard web map misstates the comparison: Myanmar at 21°N is drawn about 1.1× too large and Japan at 37°N about 1.6×, so the map shows Myanmar as 1.29× the size of Japan instead of 1.78×.
Together Myanmar and Japan cover 1,037,000 km², close to the size of Mauritania (1,036,000 km², 0.0% smaller).
The gap between them, 290,000 km², is about the size of Philippines (293,000 km²).
At Japan's density, Myanmar would have 219.8 million people (it has 53.4 million). At Myanmar's density, Japan would have 30.1 million (it has 123.8 million).
Japan's centre is 16.3° of latitude, about 1,820 km, farther north than Myanmar's.

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.
