The gap between them, 5,870 km², is about the size of Brunei (5,720 km²).
At Baja California's density, Hokkaido (Japan) would have 3.6 million people (it has 5.4 million). At Hokkaido (Japan)'s density, Baja California would have 5.0 million (it has 3.3 million).
Hokkaido (Japan)'s centre is 12.9° of latitude, about 1,430 km, farther north than Baja California's.
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.
Baja California is the 10th largest of the 32 states of Mexico and covers 3.7% of its area; it is the 20th most densely populated of them.
Hokkaido (Japan) lies about 13° of latitude (roughly 1,430 km) north of Baja California.

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.
