Junchantaiyaochuu 「純全帯么九」 is a terminal based yaku. For this yaku, every tile group and the pair must contain at least one terminal (1 or 9). Additionally, at least one tile group must contain a non-terminal tile, or else chinroutou will be scored instead. Junchan is similar to chantaiyao, but chanta allows honors in addition to terminals. This yaku is more commonly referred to as junchan 「純全」 or occasionally junchantaiyao 「純全帯么」.

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

A hand going for junchan will often discard honor tiles and middle tiles before discarding 1-3 and 7-9 tiles.

Junchan requires terminals and no honors, so it is incompatible with tanyao, ittsu, yakuhai, and shousangen. 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.

-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]].

-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.
