What fits

Saarland is 65% of the size of Ishikawa.

How they differ

Ishikawa also has the larger population: 1.1 million against 1.0 million, 1.12× as many people.
Per square kilometre that is 379 in Saarland against 275 in Ishikawa: Saarland is 1.38× as densely populated.
Their centres are about 9,240 km apart.
A standard web map misstates the comparison: Ishikawa at 37°N is drawn about 1.6× too large and Saarland at 49°N about 2.4×, so the map shows Ishikawa as 1.02× the size of Saarland instead of 1.55×.
Together Ishikawa and Saarland cover 6,770 km², close to the size of Palestine (6,070 km², 10% smaller).
The gap between them, 1,460 km², is about the size of Comoros (1,670 km²).
At Saarland's density, Ishikawa would have 1.6 million people (it has 1.1 million). At Ishikawa's density, Saarland would have 731,000 (it has 1.0 million).
Saarland's centre is 12.6° of latitude, about 1,400 km, farther north than Ishikawa's.
Ishikawa is the 36th largest of the 47 prefectures of Japan and covers 1.1% of its area; it is the 23rd most densely populated of them.
Saarland is the 13th largest of the 16 states of Germany and covers 0.7% of its area; it is the 5th most densely populated of them.
Saarland lies about 13° of latitude (roughly 1,400 km) north of Ishikawa.
Shared out evenly, each person in Ishikawa would have about 3,630 m² and each person in Saarland about 2,640 m².
Laid side by side, Ishikawa and Saarland would cover 6,770 km², 1.18× the size of Brunei.
Together they have 2.1 million people, 1.04× as many people as Slovenia.

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.
