=== Chiitoitsu ===
This yaku does not combine with [[chiitoitsu]].  By definition, chiitoitsu is formed by the collection of seven distinct pairs.  Such a definition may appear possible with ryanpeikou hands.  At every instance of ryanpeikou, the hands look like chiitoitsu hands.  However, ryanpeikou is actually composed of [[mentsu#shuntsu|sequences]], rather than as independent pairs.  The pattern simply appears as a collection of pairs, when they are actually not.  Because of this interpretation, the two yaku remain distinct and incompatible; and it is doubtful, that any [[rule variations|house rule]] allows the combination of the two yaku.

Ryanpeikou is also incompatible with other yaku that place conflicting requirements on the [[mentsu]] in the hand. [[Ittsu]], [[sanshoku]], [[sanshoku doukou]], [[toitoi]], [[sanankou]], [[sankantsu]], and [[shousangen]] are excluded as they are require either three different sequences or at least one triplet/quadruplet. [[Rinshan kaihou]] also requires a kan, so it is excluded. [[Chankan]] is incompatible because the winning tile must be unique in the winning hand---all four copies of it having been used in another player's kan. Finally, [[iipeikou]] is incompatible because it is implied by [[ryanpeikou]].
