Jihai

Definition
Jihai is the Japanese term for the honor tiles, the winds and dragons. See honor tiles for how they score, which ones count as value tiles, and when to keep or cut them.
Jihai
Jihai (字牌, じはい) are honor tiles in mahjong, the seven tiles that fall outside the numbered suit system. These tiles consist of four wind tiles (East, South, West, North) and three dragon tiles (White, Green, Red).
How Jihai plays out at the table
In standard mahjong, the tile set contains 136 tiles divided into three numbered suits (bamboo, character, and dot) plus honor tiles. The honor tiles represent a separate category with no numerical ranking or sequence relationships. This distinction makes jihai fundamentally different from suited tiles in terms of gameplay mechanics and hand composition.
The four wind tiles (kazehai) are East (Ton), South (Nan), West (Sha), and North (Pei). These correspond to the cardinal directions and play important roles in determining dealer position and bonus scoring. The three dragon tiles (sangenpai) are White (Haku), Green (Hatsu), and Red (Chun). Each dragon carries symbolic significance in traditional Chinese culture and provides distinct visual identification on the tile face.
Jihai cannot form sequences (shuntsu) with other tiles. Unlike numbered suits where 2-3-4 or 7-8-9 create valid melds, honor tiles can only be used to form triplets (koutsu) or pairs (jantou). This restriction significantly impacts hand strategy and tile selection. A hand built around honor tiles typically requires collecting three or four of the same honor tile rather than building sequences.
Honor tiles have special scoring properties. In many rule variants, completing a triplet of honor tiles awards bonus points. Completing triplets of dragons (sangenpai kou) or your seat wind (jikaze kou) provides scoring multipliers. In some variants, completing triplets of the prevailing wind (bakaze) also grants bonuses. These scoring mechanics make honor tiles valuable for hand building and point accumulation.
The purity of a hand’s composition affects scoring in certain rule systems. A hand composed entirely of honor tiles (all jihai) represents the ultimate honor tile hand and receives maximum bonuses. Conversely, hands mixing honor tiles with numbered suits may have reduced scoring potential depending on the rule variant being played.
Walking through Jihai
A player holding two White dragons and two Red dragons might prioritize completing a White dragon triplet (Haku kou) for bonus points rather than pursuing a numbered suit hand. If the player’s seat is East, completing an East wind triplet (Ton kou) would be especially valuable, as it combines jihai with seat wind bonuses.
Another scenario: During play, a player draws a North wind tile. If they already hold two North wind tiles, completing this triplet becomes strategically important. Even if the hand lacks strong numbered suit combinations, the honor tile triplet provides scoring value and moves the hand closer to completion.

Honor Tiles
字牌
Honor tiles are the seven tile types outside the numbered suits: four winds (East, South, West, North) and three dragons (haku, hatsu, chun). They never form sequences, only pairs, triplets, and quads. Their value is situational: dragon triplets always score yakuhai, wind triplets only when the wind matches your seat or the round. They anchor honitsu, chanta, and a whole family of yakuman, and a lone unpaired honor is among the safest early discards.
Kazehai
風牌
Kazehai are the four wind tiles: East, South, West, North. A wind triplet scores yakuhai only when it matches the round or your seat, and a wind matching both at once (the dealer's East in the East round) is worth two han. The rest are guest winds, valueless and usually safe early discards. All four together feed the yakuman shousuushii and daisuushii.
Sangenpai
三元牌
Sangenpai are the three dragons: haku (white), hatsu (green), chun (red). Every one is a permanent value tile, worth a han from any seat in any round, which is what separates dragons from winds. Two dragon triplets plus a pair of the third is shousangen; all three as triplets is the yakuman daisangen.
