Mahjong,originally a Chinese game, was introduced into Japan from China and the United States at about the same time, in the 1920s.

It is a game for four players, who draw and discard tiles ( equivalent to playing cards) in turn until one of the players has completed his or her hand by grouping his or her tiles into certain prescribed combinations.

It is a common saying that Mahjong is so interesting that players forget to eat and sleep.
However, we will play Mahjong over a cup of tea.
