Yakuhai is a group of yaku that focus on yakupai, or valued honor tiles.

Along with tanyao, these yaku are one of the easiest and most frequently occurring yaku in the game.

Tile patterns

Upon attaining yakuhai, the rest of the hand may be formed as any composition: open, closed, and whatever meld that helps complete the hand.

In the case of sangenpai (dragon tiles), any player may collect a set of either tile and attain the yaku for that tile.

With regards to kazehai (wind tiles), there are two yaku: one for forming a set of the seat winds, and one for a set of the round winds.

Players are assigned a particular "wind seat", relative to the dealer position, who is always seated East. For the seat wind yaku, players must collect their own set of wind tiles.

Furthermore, the game has an assigned round wind. Marked by the dealer indicator, the round wind is the same for all players. Collecting a set of this wind satisfies the round wind yaku. The first round is East, followed by South. Occasionally, the game moves into West round as well, where the West wind counts as the round wind.

If a wind is neither seat nor round wind, it is considered an off wind or guest wind. A set of such a wind is not worth any yaku.

Collecting all three sangenpai sets or all four wind sets leads to the yakuman daisangen or daisuushii.

Value

Each yakuhai koutsu (triplet) is a separate yaku worth 1 han.

If a player's seat wind matches the round wind, a koutsu of this wind counts as 2 han instead, because it satisfies two different 1-han yaku.
