(It doesn't matter what the rest of the hand is, so long as it's the "4 groups + 1 pair" winning shape. A hand can score multiple yakuhai at once.

===Why these three yaku are so important=== | |||
Whether your hand is open or closed, you can rely on riichi, tanyao, or yakuhai: | |||
* Closed hands: ''All'' closed hands have the option to declare riichi. | |||
* Open hands: Even in the highest levels of play, over 90% of open hands have either tanyao or yakuhai. | |||
Closed hands can 100% rely on riichi, and open hands can 90% rely on tanyao/yakuhai, so knowing these three yaku has the greatest returns. | |||
Riichi mahjong is heavily centered around "cheap and fast" yaku. This is because of [[dora]] (''bonus tiles''), which can add lots of value for even the cheapest hands. Therefore, many expensive hands are formed around stacking riichi + dora, rather than going for yaku. | |||
