'''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]] hand 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]]. | ||
