Prefecture Puzzle
This is a map puzzle for each prefecture. Puzzles with an icon in the top left corner of the image are also available as smartphone apps.
Prefectures that are grayed out and cannot be selected do not have a puzzle yet. We plan to create them gradually.
(Each page is designed with layouts suited for computers and tablets. For fullscreen play on smaller screens, such as smartphones, we recommend installing the store app.)
