'''Karaten''' {{kana|カラテン}}, or '''empty tenpai''', is a state where a tenpai hand does not have the ability to win.  This is due to unavailability of all instances of winning tiles.  The "visible tiles" may either be discarded, used as a dora indicator, or already exist in one's hand.  Furthermore, they may be held in other player's hands or even reside within the dead wall.  Though, the latter case is beyond a player's visibility.
