I made a development pattern of japanese dice for "dice origami (so-called folding paper art)". I made several configurations for each face pattern. Interestingly, the dices I bought in Hong Kong have the different pattern from the japanese one. Specially, their face of 2 has two black dots aligned in parallel to the side, whereas the japanese one has diagonally aligned dots in the face of 2. The pattern for japanese dice is based on that of "Taiyo Kagaku, co." who has No. 1 market-share of dices in japan.
How to fold the paper into a box(, thus dice) is exellently explained in the page.
