'''Kuisagari''' {{kana|喰い下がり}} is a property of some yaku to lose value when [[naki|called open]].  By calling on a discard and opening the hand, a player sacrifices the value of 1-han per yaku for the privilege.  Sometimes, the devalue may be viewed as disadvantageous; but the sacrifice for losing han value may be gained in the form of faster hand development.  If certain tiles may be previously discarded, a player may need to make the open call, or else risk not be able to finish the hand at all.  With the use of [[dora]], the value loss from an open call is regained anyways.

Various 1-han valued yaku may be affected by kuisagari. However, they are only denoted as "closed only", in order to remain valid. If they were to function as open hands, their value would be reduced to 0-han; and thus, it is pointless to count them as such.
Similarly, some yaku can be scored only with a closed hand. For some yaku, such as [[mentsumo]] or [[chiitoitsu]], this is necessarily the case based on their structure or nature, but for other yaku, such as [[iipeikou]], the requirement of a closed hand is entirely artificial. These yaku are not technically instances of kuisagari, because the yaku cannot be used to fulfill the yaku requirement of an open hand: they are not considered to be yaku worth 0 han. Additionally, for [[ryanpeikou]] in particular, if it were subject to kuisagari, it would score 2 han when open, but instead it is not scored at all in an open hand.


Finally, some yaku are not affected by kuisagari.  Their value is only affected in terms of [[fu]].  Even when open, they retain their original han value.  These are [[yakuhai]], [[toitoi]], [[sanankou]], [[sanshoku doukou]], [[shousangen]], [[sankantsu]], and any [[yakuman]], that allow open play.
