凄い – Enjoy Learning Japan Map Puzzle Review

Very good app. It would be even better if the regions (i.e. Tohoku, Kanto, Chubu, etc.) were color coded or otherwise distinguished. Also, the largest cities of each region could be included after the region is complete in the puzzle (i.e. Hokkaido and Sapporo, Tohoku and Sendai, etc.) Just some ideas but maybe one app isn't enough for all this detail.
