What the numbers say
Length hides the total.
Japan records 364,569.3 km² of land area, while South Korea records 97,600 km². Japan is about 3.74 times larger.
The elongated geography of Japan makes the comparison difficult to judge from neighbouring outlines alone. The circles reduce both countries to an equal visual rule.
Land area says nothing about how mountainous terrain affects settlement; it is only the physical footprint.
