Suushiihou
Both shousuushi (小四喜) and daisuushi (大四喜) are standard yakuman. They are collectively called suushiihou. Both involve the kazehai (wind tiles).

Tile diagram
The difference between the two yakuman forms are 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.

Formation
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 room to produce a single sequence.
The attempt to produce either yakuman may be detectable by open wind triplets, especially when such calls do not count for yakuhai. A hand may also be suspect when certain wind tiles are not found among the discards.
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.
