San ankou (三暗刻) is a yaku, consisting of three concealed triplets (ankou). In the case of having three triplets, the third one could not be completed with another player's discard, as this would not count as being concealed. However, if it is completed with a tsumo, then the yaku is awarded. Ankan is also counted as a closed 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.
