Jun chantaiyao 「純全帯么」 is a terminal based yaku. For this yaku, every tile group must contain at least one terminal. Unlike its yaku cousin, chanta, the pair (jantou) itself must be terminals only. This yaku is more commonly referred by its shorter name, junchan 「純チャン」.

Tile pattern

Note: 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 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 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.
