'''Chinitsu''' {{kana|清一色}} is a standard [[List of yaku#Six han|yaku]].  This yaku is composed of tiles in one suit only.  Chinitsu is worth 6 han, but it decreases to 5 han when opened.

Chinitsu is notorious for developing complex [[Machi#Complex_patterns|wait patterns]].  This is due to the homogenous nature of the yaku.  The number of potential waiting tiles may range from one tile of the suit to all nine tiles.  Strings of consecutive numbers enable this complexity.  Without the help of computers, this complexity increases the difficulty in determining the winning tiles upon tenpai.

Chinitsu requires a single suit, so that deems this yaku incompatible with other yaku that demand other tile types.  That includes [[yakuhai]], [[shousangen]], as well as [[sanshoku]] and [[sanshoku doukou]]. Since [[chinitsu]] implies [[honitsu]], the latter is not counted together. If combined with [[chanta]], the hand is actually [[junchan]], so that yaku is counted instead. Finally, [[chinitsu]] and [[honroutou]] would require a hand containing at most eight tiles (the 1s and 9s of one suit), which is impossible.

As a standalone yaku, chinitsu is at least a [[mangan]], even when open.  To regain the lost han as an open hand, it simply takes just one dora, or a combination with another yaku, just to bring the hand up to its close value of a haneman.
