Which Japanese prefecture is bigger?
Which is bigger?
Tap the place with the larger area. Trust your instinct.
Japan’s 47 prefectures make a different kind of map quiz: no names to memorise, just two outlines and a choice about their size.
All 47 prefectures
The set includes every prefecture. Islands and boundaries follow Natural Earth v5.1.2, a fixed map release rather than a live official boundary record.
Long coastlines and scattered islands make width a poor shortcut. The reveal compares the filled area of each outline, not the size of its surrounding box.

Choose the place with the larger area. The outlines start fitted to their own cards, then rescale after your answer. There is no timer or speed bonus.
The daily round resets at 00:00 UTC. Players starting the same version get the same ten questions; a round already in progress keeps its original set.
