'''Furiten''' {{kana|振聴}} is a restriction applied to winning hands.  While in furiten, the player loses the ability to declare a win on a player's [[ron|discard]] (ron).  However, the hand can still win by [[tsumo|self-draw]] (tsumo) given valid [[yaku]].  A hand in a [[tenpai]] state has a set of possible tile(s) for winning.  Primarily, the hand is marked as furiten, if any tile in that set is in the player's own discard.  Other cases involving riichi and temporary furiten are also applicable.

This rule is often used for [[defense]] purpose to determine [[Genbutsu|safe tiles]].  Tiles with the furiten rule can infer via [[suji]] and [[kabe]].  Though this may not be guaranteed barring the shape of player hands.


Furiten is translated as '''sacred discard''' in Chinese.  In consequence, English terminology had made this the equivalent.  However, this translation bears no relation to the Japanese term ({{kana|振り聴牌}}: thrown-away tenpai).
