Some restrictions are applied to kan calls:
Some restrictions apply to kan calls:
* Live wall tiles must still be available for transfer to the dead wall.  Otherwise, kan cannot be called.
* Kan cannot be called after drawing the [[Haiteihai|last tile]], as the live wall is empty and so a tile cannot be moved to the dead wall.
* Kan called four times by different players invokes [[suukaikan]].
* When [[tochuu ryuukyoku|abortive draws]] are used, [[suukaikan|four kan calls]] causes an abortive draw, unless they were all made by the same player.
* After [[naki|taking a discarded tile]], a player cannot call kan, even if a player has the tile(s) available to do so. The next chance will be after the next tile draw. Only with a '''daiminkan''' would it be possible to call kan on a discard.
* Only four kan calls can be made in a single hand. Once four kans have been made, kan can no longer be called.
* If the current tile drawn from the wall is the [[Haiteihai|last tile]], then kan cannot be called.
* After [[naki|taking a discarded tile]], a player cannot call kan, even if a player has the tile(s) available in hand to do so. They must wait until the next time they draw a tile. This does not apply when a daiminkan is called, as the kan causes a tile to be drawn immediately.
* A [[#Kan_during_riichi|kan during riichi]] cannot be called, if the tile waits are altered.  Otherwise, it is acceptable.
* A player who has declared riichi may not [[riichi#kan during riichi|declare kan]] if it changes the composition of their hand.

The most prominent restriction on kan calls involve riichi calls. 
 
When a riichi declarer holds three identical tiles and draws the fourth after the riichi announcement, the player may form an [[Kan|ankan]] from these tiles instead of discarding the fourth. The hand composition and the possible winning tiles may not change: it is not allowed to declare kan if, for some possible winning tile, any of the three identical tiles may be interpreted as part of a [[shuntsu|sequence]] or part of the pair.
