'''Sanankou''' {{kana|三暗刻}} is a yaku, consisting of three concealed triplets ([[ankou]]). The third must not be completed off of another player's [[Naki#ron|discard]], as this would not count as concealed. However, if it is completed with a [[tsumo]], then the yaku is awarded. A [[Kan#Ankan|concealed kan]] is also counted as a concealed triplet. The hand this yaku is awarded to may be open or closed, as long as it meets the conditions. This yaku is awarded 2 han.

This yaku requires three closed [[Mentsu#Koutsu|triplets]], as it is defined as such. This leaves only one allowable [[Naki|tile call]].  It can be any open [[mentsu|tile group]].

A tenpai hand with sanankou with [[toitoi]] is tenpai for [[suuankou]].  When this hand wins by discard, then the hand is not counted as suuankou.  Instead, it is the combination of sanankou and toitoi.  The fourth triplet completed by the discarded tile counts as an "open triplet", rather than a fourth closed one.
A closed tenpai hand with both sanankou and [[toitoi]] is tenpai for [[suuankou]].  When this hand wins by discard, then the hand is not counted as suuankou.  Instead, it is the combination of sanankou and toitoi.  The fourth triplet completed by the discarded tile counts as an "open triplet", rather than a fourth closed one.
