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
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 close to chanta, honor tiles may be discarded later than normal (since keeping the honors could let you go for chanta + yakuhai).
Compatibility
^ Ippatsu requires riichi to be of any use.

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.
