Junchantaiyaochuu 「純全帯么九」, or junchan 「純全」 for short, is a yaku scored when every tile group and the pair contains at least one terminal tile (either 1/9). At least one non-terminal must be present to score junchan, or the hand would score chinroutou instead. It is similar to chanta, but chanta allows the use of honor tiles.

Tile pattern

Waiting for:

Note: This hand is also waiting for , but the hand would not be counted as junchan.

Formation

All portions of the hand must contain a terminal, even the pair. At the very least, all honor tiles and all tiles numbered 4, 5, or 6 must be discarded. Even if your opening hand contains many terminals, going for junchan will slow down your hand.

Detection

Like chanta, a hand going for junchan will often discard middle tiles before discarding 1-3 and 7-9 tiles. Because junchan is similar to chanta, honor tiles may be discarded later than normal (since keeping the honors could let you go for chanta + yakuhai).

Junchan requires terminals and no honors, so it is incompatible with tanyao, yakuhai, and shousangen. Ittsu is incompatible as it requires a 456 sequence. A honitsu hand that has junchan would actually be chinitsu. A toitoi or honroutou hand with junchan would be instead chinroutou. Chiitoitsu requires seven unique pairs, but there are only six different types of terminals. Finally, because junchan implies chantaiyao, both cannot be counted with a single hand.

-'''Jun chantaiyao''' {{kana|純全帯么}} is a terminal based [[yaku]].  For this yaku, every [[mentsu|tile group]] and the [[jantou|pair]] must contain at least one [[terminal]].  Additionally, at least one tile group must contain a non-terminal tile, or else [[chinroutou]] will be scored instead. Junchantaiyao is similar to [[chantaiyao]], but chantaiyao allows honours in addition to terminals. This yaku is more commonly referred by its shorter name, '''junchan''' {{kana|純チャン}}.

-All portions of the hand must contain a terminal, even the [[Jantou|pair]].  At the very least, all tiles numbered 4, 5, and 6 must be discarded and also the honor tiles.  This restriction may slow down the process of developing a junchan hand; and it is only viable and advisable to consider junchan, when the [[haipai|opening hand]] contains various terminals.

 === Detection ===
-Per the development of the hand, a player is likely forming a junchan hand when the discards show a mix of honor tiles and tiles numbered 4, 5, and 6.  Sometimes, the tiles numbered 2 and 3 may be included; as specific terminals may be used for triplets.  Furthermore, junchan is often used for open hands, in order to speed up tile development.

-Junchan is compatible with a large number of yaku. Because it implies [[chantaiyao]], both cannot be counted with a single hand. Because it requires that the hand have no honours or tiles 2-8, it is incompatible with [[tanyao]], [[yakuhai]], [[shousangen]]. A [[honitsu]] hand that has junchan would actually be [[chinitsu]]. [[Ittsu]] cannot be combined as it requires a 456 sequence, which does not include a terminal. Finally, as there are only six different types of terminal tiles, junchan cannot combine with [[chiitoitsu]].
+Junchan requires terminals and no honors, so it is incompatible with [[tanyao]], [[yakuhai]], and [[shousangen]]. [[Ittsu]] is incompatible as it requires a 456 sequence.

[[Chiitoitsu]] requires seven unique pairs, but there are only six different types of terminals. Finally, because junchan implies [[chantaiyao]], both cannot be counted with a single hand.
-If junchan is combined with [[toitoi]], the hand must contain all terminals, and is thus the [[chinroutou]] yakuman. Because junchan is incompatible with chiitoitsu and [[honroutou]] must be combined with either toitoi or chiitoitsu, a junchan honroutou is necessarily scored as chinroutou as well.
