-'''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. However, the latter case is beyond a player's visibility.
+'''Karaten''' {{kana|カラテン}}, or '''empty tenpai''', is a [[tenpai]] hand that cannot win because all possible winning tiles are unavailable.  The "visible tiles" may either be discarded, used as a dora indicator, and/or already exist in one's hand. In addition the tiles may be held in other players' hands or in the dead wall, but these would be unknown to the player.
+Karaten hands are generally considered tenpai for the purpose of [[Ryuukyoku]], except if all four copies of the winning tile are in the player's own hand.
 ==The fifth tile case==
-The term is often confused with the "fifth tile" case.  Here, a hand waiting for a fourth tile that is simply hidden, discarded, or used by someone else remains a valid tenpai in all circumstances. A hand may contain a 1-2 [[Penchan|penchan]] and a previously declared [[Kan|kan]] of 3-3-3-3 in the same suit.  This renders the threes unavailable as winning tiles. Some platforms would consider this case as tenpai, while others may deem it as noten.  As always, this depends on the rule variations.
+When a hand has all four copies of a tile, and is waiting on a fifth copy of a tile, it is often not considered tenpai at all. Example:
+{{#mjt: 123456789m5555p}} Waiting for: {{#mjt: 5p}} (impossible)
+If this hand could obtain a fifth 5-pin, it could win by completing a triplet and pair.
-'''Example:'''<br>
 {{#mjt:12m444p678s1180z33m0z}}  Waiting for: {{#mjt:3m}}
+Similarly, this hand could complete a sequence if there was a fourth 3-pin.
+This is subject to rule variation. In some platforms, hands like these still count towards tenpai. They usually don't, though.
