Suushiihou
Suushiihou 「四喜和」 are the two wind-based yakuman. Though instead of the reference of "suushiihou", they are instead individually noted as shousuushi 「小四喜」 and daisuushi 「大四喜」. Both involve groups of all four kazehai (wind tiles).

Tile diagram
The difference between the two yakuman forms is subtle. Shousuushi only need a complete group of three out of the four wind types, while pairing up the fourth type. On the other hand, daisuushi requires a complete group for all four wind types.

Development
Both yakuman require all four kazehai (wind types). Given the nature of kazehai, both yakuman are dependent on triplets. The ability to call pon makes it easier to form either yakuman; yet the options to do so are limited. Unlike daisuushi, shoususshi has greater flexibility regarding tile waits, due to the single sequence if needed. Daisuushi is limited to either shanpon or tanki, while shousuushi may also include ryanmen and kanchan as options too.
Viability
The attempt to produce either yakuman may be made possible by possession of at least pairs of the wind tiles. With this, a player is given the option to increase the chance for yakuman with the option of calling needed wind tiles. In the end, a player must have tile groups of at least three to even have a chance for completion. If three out of four of a wind type is discarded or made unavailable, then the option for either yakuman is nullified.
Value
Shousuushi and daisuushi both have the value of a yakuman and therefore award 32000 points to a non-dealer winner or 48000 points to a dealer winner. However, as daisuushi is a rarer yakuman, in rulesets where a double yakuman is allowed, it is counted as such and awards 64000 points to a non-dealer winner or 96000 points to a dealer winner respectively.
