There are 144 tiles in the Japanese tile set. Once again there are usually no Roman or Arabic numerals and they only have the Chinese characters to read to determine the winds, dragons and character tiles. The Japanese use blank tiles as white dragons (there are no tiles marked with a rectangle in these sets). Some sets have only 4 Flower tiles (these are Seasons) but this is very rare as they are not used in most of the modern Japanese games. Some of more traditional sets contain 4 Red Fives which are used for added bonuses. The One Dot tile (and most of the dots) contain a five-petaled design within the dot. some assume that this is to represent the plum blossom, which was the imperial emblem of an emperor or shogun of Japanese history.
