Honiisou {混一色) is a standard yaku. Normally translated as a "half flush", this yaku features a hand composed only of honour tiles and tiles of a single suit. If the hand contains no honours, then the chinitsu yaku is counted instead. This yaku is usually referred to as honitsu or, occasionally, honichi.
Tile pattern
Agari: or
Bakahon
Bakahon 「バカホン」 is a slang term for a basic honitsu with open calls. No other han are scored, either from yaku or dora, meaning that the hand will score low (usually 2000-3000 points).
Formation
Detection
A player's discard pile may lack one particular suit. This may be an indicator of a honitsu hand being developed.
Compatability
^ Ippatsu requires riichi to be of any use.

Honitsu is aligned to a single suit. Therefore, this yaku is compatible with other yaku, that follows that pattern; and multiple suited yaku do not apply, namely sanshoku and sanshoku doukou. Naturally, the "single suited" yaku of ittsu can merge with honitsu, only if the fourth tile group is of the same suit or is a set of honours. Other yaku are able to function with multiple suits; but they are also possible using single suits, namely toitoi and sanankou. The same applies for chiitoitsu. Commonly, this yaku works with yakuhai, and likewise, shousangen.
Of course, honitsu is not compatible with chinitsu, because every chinitsu hand is honitsu. A honitsu combined with a tanyao would actually imply the chinitsu instead, since there would be no honours. It is also not compatible with junchan, as that would require the hand to contain only 1s and 9s of the same suit, which is only eight available tiles.
