GAME INFOGreat educational game to help you learn about geography of Japan. Drag and drop maps of prefectures where they should be. You can see additional data like, capital, area and population. Pick to play it in English or Japanese.
The game has two modes, easy and full. In both of them, the aim is to drag and drop the map on the right place. You can make it a bit easier if you turn on 'help' mode, to see prefecture borders. You can also zoom the map to see the 'bigger' picture.
