Depending on rulesets, variation exists between allowing [[ankan]] or not.

* Value: 1 han

=== Kanburi ===

=== Sangen chiitoitsu / Suushi chiitoitsu ===

'''Sangen chiitoitsu''' {{kana|三元七対子}} / '''Suushi chiitoitsu''' {{kana|四喜七対子}} is a [[chiitoitsu]] hand containing all of three different pairs of [[sangenpai]] / four different pairs of [[kazehai]] correspondingly.

* Examples:

=== Uushin tsuukan ===

'''Uushin tsuukan''' {{kana|五心通貫}} is a specific [[ikkitsuukan]] hand with a [[kanchan]] wait of 5 on its straight part. That being said, a hand containing an identical suit of 123-46-789 waiting for 5.

* Value: Usually 1 additional han based on ittsuu.

== Two-han yakus ==

'''Sanshoku tsuukan''' {{kana|三色通貫}} (lit. ''Three-color straight'') is a hand containing [[shuntsu]]s of 123, 456 and 789 both in different suits.  Also called '''Sanshoku ittsuu''' {{kana|三色一通}}, or '''Hon ikkitsuukan''' {{kana|混一気通貫}} (lit. ''Mixed straight'').

* Value: 2 han (1 han when opened)

When their suits are identical, it becomes the standard yaku [[ikkitsuukan]].

=== Kyandonhou ===

More specifically, the hand is built by: a sequence X in suit A, the sequence X in another suit B, another sequence Y in suit A, and the sequence Y in suit B. No restriction on the pair in general.

* Value: 2 han (closed-hand only, or allowing opened-hand with 1 han)

When their suits are identical, it becomes the standard [[ryanpeikou]] hand.

'''Shoutate''' {{kana|小タテ}} (''Little 3-color triplets'') is a hand containing two triplets and a pair with a same number in three different suits.

* Value: 2 han

* Trivia:

** This local yaku is mainly used in [[wikipedia:Hokkaido|Hokkaido]] region.

* Value: Both are 2 han in general

* Examples:

** {{#mjt:222888p234s77z}} {{#mjt:555'p}} (Sujipaikou)

** {{#mjt:22m111555s}} {{#mjt:5'67p}} {{#mjt:99'9s}} (Chousankou)

A variation exists if those triplets are in three different suits: '''Sanshoku choupaikou''' {{kana|三色跳牌刻}} / '''Sanshoku sujipaikou''' {{kana|三色筋牌刻}} / '''Sanshoku chousankou''' {{kana|三色頂三刻}}.

* Value: 1 or 2 han

=== Suuzuukou ===

* Value: 2 han (supersedes the normal riichi)

* Value: 3 han (supersedes the normal daburu riichi)

'''Sanpuukou''' {{kana|三風刻}} (lit. ''Three wind triplets'') is a hand with three triplets of [[kazehai]]s.

* Value: 2 han in general

A variation exists if all the three wind triplets are [[otakaze]]s: '''Otakaze sankou''' {{kana|客風三刻}} (lit. ''Three guest-wind triplets'').  It is only avaiable for the player with their seat wind identical to the current prevalent wind, e.g. East player in East round, or South player in South round, and so on.

** {{#mjt:99p34s777m}} {{#mjt:11'1s}} {{#mjt:777'z}} <br/>&emsp; ↓ Declare daiminkan on kamicha's discard 7-man;

** {{#mjt:99p34s}}, Rinshan {{#mjt:1s}}, {{#mjt:7'777m}} {{#mjt:11'1s}} {{#mjt:777'z}} <br/>&emsp; ↓ Declare kakan on rinshanpai 1-sou;

Uncommonly found in the rulesets, some variation allows to apply a higher han if more consecutive kans are happened.

=== Tanfonhou ===

: Pinzu of 2 / 4 / 8,

: Souzu of 2 / 3 / 4 / 6 / 8,

=== Shanron chonchu ===

: The two groups of [[shuntsu]]s are limited in manzu and souzu;

: The head pair is restricted to pinzu;

* Value: Mangan / Baiman / Yakuman

=== Maneman ===

* Value: Yakuman

* Example:

* Trivia:

** The name of yaku is an idiom about patience. It comes from the aphorism {{kana|石の上にじっと3年も座っていれば、石も暖まる}}, meaning "even a cold stone can be warmed if someone sits on it for three years", indicating the perseverance leads to a success.

'''Shiisanpuutaa''' / '''Shiisanputou''' {{kana|十三不塔}} (lit. ''Thirteen unconnected'') is a special starting hand with none of the two tiles (in thirteen different tiles) can be formed as a [[taatsu]], aside from exactly one pair.

* Value: Yakuman

Likewise, if all the fourteen different tiles are mutually exclusive, this starting hand becomes '''Shiisanuushi''' {{kana|十三無靠}}.  Sometimes also noted as '''Shiisuupuutaa''' / '''Shiisuuputou''' {{kana|十四不塔}} (lit. ''Fourteen unconnected'').

'''Suurenkou''' {{kana|四連刻}} (lit. ''Four consecutive triplets'') is a hand containing four triplets (or quads) in one suit where their numbers are increased by 1.

* Value: Yakuman

The following hand is also called '''Junsei suurenkou''' {{kana|純正四連刻}} (lit. ''Pure four consecutive triplets''): [[shanpon]]-machi with either waits ensures a suurenkou.

The winning condition may vary between closed-hand only, or opened-hand allowed.  Though even with an openable choice, this hand is still pretty rare, and really hard to accomplish.  The difficulty comes from the process of collecting those twelve tiles with continuous numbers in one suit, while only the [[kamicha]] can help to feed the tiles.  This is also why this yaku generally doesn't apply the [[kuisagari]] rule to downgrade the value of an opened hand, which is usually widely applied for shuntsu-based yakus.

* Value: Yakuman

The rule of [[sekinin barai]] can be applied in this yakuman hand.  Due to the limitation on claiming [[Naki#Chii|chii]], only kamicha can be the target of responsibility.

=== Hyakuman goku ===

* Value: Yakuman

* Examples:

* Some variation may exists as follows:

** Only scores the exactly 100 cases as a yakuman.

** May allow summing up a hand for [[honitsu]].

* Trivia:

== Yakumans related to specific tiles ==

* Value: Yakuman

* Trivia:

** The yaku name originates from the verse {{kana|萬緑叢中紅一點}}, lit. ''A little <span style="color:red;">red</span> in the <span style="color:green">greenery</span>''.

=== Kokuiisou ===

The hand is available in either [[toitoi]] or [[chiitoitsu|chiitoi]] form.

'''Touhoku Shinkansen''' {{kana|東北新幹線}} (''Tohoku Shinkansen'') is a hand built with [[kazehai]] East and North as the pair and a triplet, and an [[ikkitsuukan]] hand as the rest.

* Value: Yakuman (usually closed-hand only)

* Example: {{#mjt:123456789s11144z}}

* Trivia:

** This yaku is considered to be designed in 1980s, when the rail line of [[wikipedia:Tōhoku_Shinkansen|Tohoku Shinkansen]] is completed and opened.

'''Chousangen''' {{kana|超三元}} (lit. ''Super 3 dragons'') is a hand containing all three quads of [[sangenpai]]s.

* Value: Double yakuman

When chousangen is not recognized, such hand values single yakuman as [[daisangen]].

=== Daichisei ===

{{main|Daichisei}}

* Value: Double yakuman

When daichisei is not recognized, the hand values single yakuman as [[tsuuiisou]].

'''Junsei ryuuiisou''' {{kana|純正緑一色}} (lit. ''Pure all green'') is an [[ryuuiisou|all-green]] hand built only with the [[souzu]] tile of 2, 3, 4, 6 and 8, which excludes [[hatsu]].

* Value: Double yakuman

When junsei ryuuiisou is not recognized, the hand may value:
