Clear Mahjong described here is adapted from Fukomoto's Ten. The game is a race between two teams of two players to complete each of five yaku at least once.
It is a variation on Japanese mahjong. In the final showdown between East and West, Clear Mahjong (with no exchange of points) is proposed by Ten. Harada accepts these rules with the condition that points are used alongside Clear Mahjong.

Clear Mahjong is a race to complete each of five two han yaku at least once.
- Ikkitsukan (3 chows of 1-2-3, 4-5-6 and 7-8-9)
- Sanshoku Doujun (3 chows of 3 different suits of the same numerical sequence)
- Chanta (All four sets and the pair contain a terminal or honor)
- Chiitoitsu (Seven Pairs)
- San'ankou (3 concealed pungs)
In addition, each player starts the han-chan with 25,000 points. These points carry over to the next han-chan if necessary (i.e. if a player finishes a han-chan with 500 points, he will start the next han-chan with 500 points).
The first team to complete each yaku at least once wins the game. However, if any player drops below zero points, then his side loses instantly. If a team meets both of these conditions in the same hand, then the game is drawn.
