Yakuhai 「役牌」 is a group of yaku that focus on jihai, or 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.

Yakuhai are dependent among the different honor tiles. 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), yakuhai counts for the players in relation to their current wind seating and the current wind round.

Players are assigned a particular jikaze 「自風」, or 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. For this, it is necessary for players to be aware of the current wind seating. This can easily be noted by paying attention to the dealer position.

Furthermore, the game has an assigned round wind. Typically, the round wind is denoted by either East or South. Occasionally, the game moves into West round as well, where the West wind counts as the bakaze 「場風」, or round wind. Marked by the dealer indicator, the round wind is the same for all players; and it only changes after all players had a chance to sit as East for at least one hand, when the game moves from the East round to the South round. Collecting a set of this wind satisfies the round wind yaku. Essentially, the round wind functions like the dragon tiles, where any player may collect them and have them counted for yakuhai. Finally, a tile grouping of the round wind work in conjunction with the wind seating. When seated as the same wind with the round wind, then the tile group counts double, such as Double East or Double South.

If a wind is neither seat nor round wind, it is considered as an otakaze 「客風」 (off wind or guest wind). A set of such a wind is not counted towards yakuhai. Open calls for such wind tiles forces players to resort to other yaku for completion.

Finally, four yakuman utilizes the honor tile groups. All three groups of sangenpai creates daisangen. The wind tiles can be used for either shousuushi or daisuushii. An assorted groups of honor tiles form tsuuiisou.

Usage

Along with tanyao, yakuhai are among the easiest yaku to learn and use. It is the simple collection of particular wind tiles or any group of dragon tiles. As for the rest of the hand, players are free to form any tile grouping, that they wish whether open or closed. Typically, yakuhai are open hands, as possession of the appropriately paired tiles makes it easy to complete by calling on the discarded third tile, or sometimes fourth. This ability makes this yaku exceptionally convenient, for the completion of fast hands.

Value

Each yakuhai koutsu (triplet) is a separate yaku worth 1 han. However, the value can be dramatically increased if the particular yakuhai koutsu is indicated as the dora. As dora, a hand is already guaranteed 4 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. Typically, this involves the east and south winds, as games normally involve the east round (tonkyoku) and south round (nankyoku) rounds. Of course, this may apply to the west round (shaakyoku).

YAK

Yakuhai essentially works with any yaku, that has room or allows the use of honor tile groups, which gives it a great amount of versatility. Shousangen requires not just one, but two yakuhai. Honitsu is most effective, with the use of at least one yakuhai group.

The definitions of tanyao, junchan, and chinitsu eliminates the use of honor tiles all together. As for chiitoitsu, honor tiles may be used, but its inability to use triplets deem its incompatibility. Finally, yakuhai groups generate fu; and this does not work with pinfu.
