Aryanmen 「亜両面」 is a variation on the ryanmen waiting pattern, where the two tiles completing the sequence are next to a pair of one of the waiting tiles. As a result, the hand also has a pair wait on that tile. It is generally a weaker wait, however, as the pair uses up two of the eight possible waiting tiles, leaving only six possible tiles to win off of.

In this example, the underlying ryanmen wait is based on the 67m, but additionally, 567m can be viewed as a complete sequence, in which case the other 5m creates a pair wait.


When aryanmen is won with the waiting tile not already present in hand, the wait can only be interpreted as a ryanmen wait, and it will score 0 fu.

When aryanmen is won with the waiting tile already present in hand, it can be interpreted as either a tanki or ryanmen wait. In this case, the highest-scoring option must be chosen. Normally, this will be the 2 fu for a tanki wait, but if the hand qualifies for the pinfu yaku, that will be scored instead.
