Gakken Prefectural Karuta The cover seals on the prefecture names can be attached and removed, but some of the initial letters of the reading text have cover seals, while others have regular white stickers that cannot be cleanly removed. Also, spare cards and the Japan map & blank map are missing. This was helpful for elementary school social studies classes to memorize all the shapes and names of the prefectures. I got to the point where I could answer immediately just by looking at the shapes.
