Japanese mahjong

Japanese mahjong (Japanese: 麻雀, Hepburn: Mājan), also known as riichi mahjong, is a variation of mahjong. While the basic rules to the game are retained, the variation features a unique set of rules such as riichi and the use of dora. The variant is one of a few styles where discarded tiles are ordered rather than placed in a disorganized pile. This is primarily due to the furiten rule, which takes player discards into account. The variant has grown in popularity due to anime, manga, and online platforms.
