'''Atozuke''' {{kana|後付け}} describes a "yakuless" [[tenpai]] which gains [[yaku]] upon winning. In other words, the current state of the hand does not produce yaku while tenpai. This typically involves an open hand, but can also apply to closed hands without [[riichi]]. It is also called '''sakizuke''' {{kana|先付け}}. | '''Atozuke''' {{kana|後付け}} describes a "yakuless" [[tenpai]] which gains [[yaku]] upon winning.

However, it is usually unable to win off the "[[yasume|lesser]]" tile, since it would lack yaku. Such hands may still win with the lesser tile if it gains a conditional yaku (like [[haitei]] or [[rinshan]]). Otherwise, it cannot win. Thus, if the lesser tile is drawn, the hand may be subject to [[furiten]]. | ||

*In this case, the hand has a closed hatsu triplet, so it can always win. Even if the hatsu triplet was drawn after the 789-sou call, there would be no practical way to prove you didn't have the hatsu triplet before calling. Therefore, "drawing yaku after calling" is allowed so long as you "complete" the yaku before winning. | |||
*For whole hand yaku, like [[honitsu]] and [[chanta]], the hand's closed section is considered to have "guaranteed the yaku". Therefore, even if the hand didn't qualify for honitsu at the time of the first call, you can win with an open honitsu-only hand. (For a yaku like chanta, your waits still need to guarantee chanta to not be atozuke.) | |||
