Tanyao 「断幺九」 is a yaku, consisting of tile groups using numbered tiles 2-8 of any of the three main suits. Any tile numbered 2-8 are classed as chunchanhai 「中張牌」, or simples. Conversely, this yaku must lack the terminal tiles (1 and 9) as well as any honor tiles. Among the yaku, this is one of the more easier to attain; and it is also a cheap yaku. In addition, this yaku may be subject to rule variation of allowing or disallowing its count when opened.
Tile pattern
Agari: or

or
As long as every tile is neither a terminal nor an honor tile, then the yaku is counted.
Kuitan
Kuitan 「喰い断」 is a rule allowing open tanyao. If kuitan is disallowed, then it would be specified as "kuitan nashi", and tanyao would be restricted as a closed only yaku. Tanyao takes special interest, due to the ease of its viability. This ease is due to overall number of available tanyaochuu, or simples tiles numbered 2 through 8.
Formation
Tiles numbers 2-8 are designated as "simples". Its converse, the 1 and 9 tiles plus honor tiles, is grouped as the terminals and honors. So, in order to form a hand with tanyao, players simply discard the terminal and honor tiles. Given the range of the simple tiles, the number of tiles available to form this yaku is a wide range. This availability makes this yaku a particularly fast one to develop. It is even faster, when used in open fashion. Although, some rules may vary, which disallows the use of tanyao for open hands.

Naturally, tanyao is compatible with any yaku that does not utilize yaochuuhai, which are the terminals (1's and 9's) or honor tiles. The six yaku incompatible with tanyao all use such tiles in some way or another.
With chinitsu and chiitoitsu
Some special optional yakuman are considered when in combination with chinitsu and chiitoitsu simultaneously.
- Pinzu (circles), dai sharin – 「大車輪」 or big wheels
- Souzu (bamboo), dai chikurin – 「大竹林」 or bamboo forest
- Manzu (characters), dai suurin – 「大数隣」 or numerous neighbours
Value
The speed of the hand's development justifies the value of the hand at 1-han. This speedy play is associated with cheap value. However, if red fives and other dora are incorporated, then a simple tanyao hand can easily become a very high-scoring one.
