Yakuhai 「役牌」, or Fanpai 「飜牌」, is a group of 1 han yaku scored for completing a group of honor tiles. Along with tanyao and riichi, these yaku are the easiest and most frequently occurring yaku in the game. Dragon tile groups always count for yakuhai. Wind tiles only count for yakuhai if they are the round wind or the player's seat wind; other winds are considered offwind or otakaze 「客風」 and do not grant a yaku or any han, though they may still form valid triplets for the purpose of making four sets and a pair for a complete hand.
Tile patterns
| Yakupai | Kanji | Yakupai | Kanji |
|---|---|---|---|
| East seat | 自風 東 | East round | 場風 東 |
| South seat | 自風 南 | South round | 場風 南 |
| West seat | 自風 西 | West round | 場風 西 |
| North seat | 自風 北 | Green dragon | 役牌 發 |
| Red dragon | 役牌 中 | White dragon | 役牌 白 |
All that is required for yakuhai is a single triplet or quad of an eligible tile. The three dragon tiles are always eligible, but among the wind tiles, only the round wind and the player's seat wind are eligible. Guest winds are ineligible.
Yakuhai is not a single yaku but rather a collection of five yaku (one for each dragon, one for the round wind, and one for the seat wind). The five are all compatible with each other and they can be scored in any combination, except that all three dragon yakuhai will lead to daisangen instead. If the round wind and seat wind are the same, then both are scored for that group.
Examples
Agari:
The triplet of the green dragons satisfies the yaku regardless of seating and wind round.
-
Agari:
Here, the triplet of the east wind satisfies the yaku if this hand is scored during the east round, or by the dealer in any round. In the east round, the dealer will score the double east wind as 2 han.
Agari:
Each of the dragon quads scores 1 han for its own yakuhai. They are scored separately, and the fact that they are quads rather than triplets is irrelevant in the scoring. The additional pair of red dragons means that the hand scores shousangen in addition to, but not instead of, the double yakuhai.
Usage
Along with tanyao, yakuhai are among the easiest yaku to learn and use. As the honour tiles are generally weak due to their inability to form sequences, they are often discarded early in the hand. A player starting with a pair of eligible tiles can usually pon a third, instantly satisfying the yaku requirement. This ability makes this yaku exceptionally convenient for the completion of fast hands. Therefore, this yaku is also sometimes called an express ticket.
Players looking for a quick win will often hold lone yakuhai tiles a little longer than their tile efficiency would dictate, in hopes of getting a second and then calling (or drawing) a third to make a yakuhai. This is particularly true with hands that will have difficulty completing an open tanyao, either because they have lots of terminals or honours, or because open tanyao is not allowed.
Atozuke
Agari: or
Yakuhai hands may commonly be used for atozuke. Here, the hand depends on yakuhai for yaku, where among the multiple waiting tiles, one of them is a yakuhai tile. However, the other waiting tile(s) may not produce a yaku, unless it wins via chankan, rinshan, haitei, or houtei.
Terminology
While yakuhai can be referred to collectively and it is rarely ambiguous, it is not uncommon to call them out individually, particularly when scoring a hand by announcing its yaku. The table to the right shows the written forms of most of the yakuhai. Some game platforms count statistics on the individually different yakuhai, by dragons and winds. Others collect them all under one statistic.
For example, a dealer winning the previous hand during the east turn wouldn't say: "three yakuhai", but rather: "double east, red dragon". This makes the origin of each han clearer.

Yakuhai essentially works with any yaku which allows a triplet and allows honor tiles. Tanyao, junchan, and chinitsu forbid honor tiles. Pinfu and ryanpeikou do not allow triplets. Chiitoitsu requires seven distinct pairs, also preventing triplets.
Honitsu is one of the most effective combinations with at least one yakuhai group. This yaku is compatible with itself. Different groups of yakuhai tiles may be collected into one hand; and in turn, they are treated as separate yaku, despite identical functionality. In particular, shousangen requires not just one, but two yakuhai.
