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.
