When calling kan, a player must draw an extra tile; and that tile comes from the dead wall.  This is the '''rinshanpai''' {{kana|嶺上牌}}.  If the hand is completed with this tile draw, then this yaku is awarded.  It is quite possible for rinshan to be the only yaku for the hand.  Usually, players already have other yaku.

The 5-man draw places this hand in tenpai with a tile needed to be discarded.  In order for this hand to proceed to tenpai, either kan must be called or one of the hatsu is to be discarded.  If after the kan, a dead wall draw of 7-sou awards rinshan kaihou.  Otherwise, the unwanted rinshanpai may be discarded and [[riichi]] be called.

Rinshan kaihou is generally compatible with any hand, that can accommodate kan calls. This rules out any yaku dependent on all sequential tile groups, namely both [[pinfu]] and [[ryanpeikou]].  Other yaku, such as [[sanshoku]] and [[ittsu]], are also sequential based, but they have room one triple tile group to be upgraded for a kan callBy definition, [[chiitoitsu]] requires every [[toitsu|tile pair]] to be unique; so kan calls cannot be performed here.  With [[chankan]], this yaku uses another player's kan call rather than one's own.
Rinshan kaihou is generally compatible with any hand that can accommodate a kan call. This rules out [[pinfu]], [[ryanpeikou]], and [[chiitoitsu]], as these hands do not allow kan.  [[Chankan]], [[haitei]], and [[houtei]] all require winning from a different location than a kan replacement tile (another player's kan, the live wall, and another player's discard, respectively) and so cannot combine with rinshan. Finally, a kan would interrupt a chance for [[ippatsu]].

Rinshan kaihou cannot be combined with [[haitei]], a yaku for calling tsumo on the final tile from the live wall. When winning on the replacement tile after a kan, tsumo is not called on any tile from the live wall, but on a tile from the dead wall.  However, the last tile draw indicated by the '''haiteihai''' is defined as the last tile to be drawn from the live wall, not the deal wall.
