Okinawa: Part of this region's boundary is disputed with China and Taiwan. 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

Nakhon Pathom is 98% of the size of Okinawa.
Okinawa is larger by 44.0 km² (17.0 mi²), which is 2.1% of the area of Nakhon Pathom.
Measured in Belgiums: Okinawa is about 0.07, Nakhon Pathom about 0.07.

How they differ

Okinawa also has the larger population: 1.5 million against 921,000, 1.59× as many people.
Per square kilometre that is 680 in Okinawa against 438 in Nakhon Pathom: Okinawa is 1.55× as densely populated.
Their centres are about 3,080 km apart.
A standard web map misstates the comparison: Okinawa at 26°N is drawn about 1.2× too large and Nakhon Pathom at 14°N about 1.1×, so the map shows Okinawa as 1.19× the size of Nakhon Pathom instead of 1.02×.
Together Okinawa and Nakhon Pathom cover 4,250 km², close to the size of Cape Verde (3,930 km², 7.6% smaller).
At Nakhon Pathom's density, Okinawa would have 940,000 people (it has 1.5 million). At Okinawa's density, Nakhon Pathom would have 1.4 million (it has 921,000).

Nakhon Pathom is the 67th largest of the 77 provinces of Thailand and covers 0.4% of its area; it is the 8th most densely populated of them.
Okinawa lies about 12° of latitude (roughly 1,330 km) north of Nakhon Pathom.
Shared out evenly, each person in Okinawa would have about 1,470 m² and each person in Nakhon Pathom about 2,290 m².
Laid side by side, Okinawa and Nakhon Pathom would cover 4,250 km², 1.08× the size of Cape Verde.
Together they have 2.4 million people, about as many people as Moldova.
Okinawa is drawn from 133 points and Nakhon Pathom is drawn from 42 points: at sizes under 2,500 km² the outlines are a sketch, so the overlap shows the proportions rather than the exact shape.

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.
