Local yaku

Local yaku 「ローカル役」, also known as ancient yaku 「古役（こやく）」, are the yaku not used in the standard ruleset of Japanese mahjong. A given set of rules may include any combination of local yaku. Due to the large variety of local yaku, this page will be an incomplete list.

Mangan for actions taking on specific tiles

The following yaku are achieved by taking actions on some particular tiles. These yaku are often inspired by idioms, verses, or simply the tile patterns.

There are two common scoring mechanics on them:

1. Directly scored as a mangan, unless the hand can be scored higher in another way.
2. An additional 1 han for the specific operations, which in essence values 2-han in total.

Sometimes both two scoring methods are applied simultaneously, where the higher scoring one is used.

Kinkei dokuritsu

Kinkei dokuritsu / Chinchi dourii 「金鶏独立」 (lit. A golden rooster standing alone) is a four-melded hand waiting for 1-sou's hadaka tanki. Ankans are allowed. Also called Chinchiihou 「金鶏和」.

Renhou

Main article: Renhou

Renhou 「人和」 (Humanly hand, Hand of man, Blessing of human) is a yaku achieved by a non-dealer player wins by ron with their starting hand, before drawing a tile. Similar to tenhou and chiihou, any calls will nullify the yaku.

Can be treated as a 4 han yaku or 8 han yaku (allowing it to stack with regular yaku).

Maneman

Maneman 「真似満」, also called Maneshi mangan 「真似満貫」, is a yaku achieved by mimicking opponent's discards. The most common rule is: if a player has their discards identical to some opponent in the first row (usually from 1st to 5th / 6th turn), maneman is applied, and the opponent will pay out a mangan if that player wins.

Similar to nagashi mangan, the condition breaks if anybody calls a tile related to the maneman. An opponent calling a tile after maneman is fufilled will not cancel the maneman.

• Value: Mangan

Some variations exist:

• Can only imitate the discards from a dealer, meaning only non-dealers can achieve this yaku.
• Value can be increased if more tiles are mimicked, e.g. 7th turn haneman, 9th turn baiman, and so on.

Yakuman

Paarenchan

Paarenchan 「八連荘」 (lit. Eight consecutive dealership) is a special winning state related to renchan. Roughly speaking, if a player successfully keeps his dealership for eight continuous rounds, or simply wins eight hands continuously, the hand he won at the last time will be automatically scored as a yakuman, as long as it is a valid winning hand.

More specifically, there are three main variants to determine a paarenchan:

Definition 1: Winning eight hands consecutively, no matter if the player is the dealer at that round.

Definition 2: Winning eight hands continuously exactly in his own dealership (as how the yaku name strictly indicated).

Definition 3: Successfully accumulates eight honba points on his own. Usually a hand must be won at the last honba, while it doesn't matter for the previous ones.

Rulesets that include paarenchan will usually include the optional restriction of ryanhan-shibari, which is applied dealer after the fifth round. (This means that, past the 5th honba, each winning hand must be 2+ han.)

• Value: Yakuman

The following charts show their differences on tracking a valid state of paarenchan:

Round	Honba counter	Player's wind	Paarenchan counter
			Def. 1
East 1 R.	0 honba	North	1	Agari
East 2 R.		West	2
East 3 R.		South	3
East 4 R.		East (dealer)	4
	1 honba		5
	2 honba		6
	3 honba		7
	4 honba		8

Round	Honba counter	Player's wind	Paarenchan counter
			Def. 2		Def. 3
East 1 R.	0 honba	North	Ryuukyoku
East 2 R.	1 honba	West
East 3 R.	2 honba	South
East 4 R.	3 honba	East (dealer)	-	Tenpai	1	Agari
	4 honba		1	Agari	2
	5 honba		2		3	Tenpai
	6 honba		3		4	Agari
	7 honba		4		5
	8 honba		5		6	Tenpai
	9 honba		6		7
	10 honba		7		8	Agari
	11 honba		8		-

Depending on ruleset, the dealership may automatically rotate after paarenchan, or allowing the dealer to continue the next loop of paarenchan progress.

Pouhoi paarenchan

Only used alongside paarenchan. If a non-dealer breaks opponent's dealership successfully at the round the dealer can achieve paarenchan, Pouhoi paarenchan 「破回八連荘」 (lit. Destroyed eighth-dealership) is achieved. The non-dealer winner will automatically scored a yakuman.

• Value: Yakuman

Unlike paarenchan, the ryanhan-shibari restriction is not applied to the non-dealers.

In some ruleset, the winning condition is limited to either tsumo, or ron from the dealer.

Ishino uenimo sannen

Ishino uenimo sannen 「石の上にも三年」 (lit. Three years on a rock) is a yaku achieved by winning a double-riichi hand with haitei raoyue or houtei raoyui.

• Value: Yakuman
• Example:
  • Double riichi: , Houtei ron:
• Trivia:
  • The name of yaku is an idiom about patience. It comes from the aphorism 「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.

Toukanhou

Toukanhou 「頭槓和」 (lit. First-kan win) is a yaku achieved by claiming a kan in the first turn and winning with rinshan kaihou immediately.

Similarly to tenhou and chiihou, the yaku will be nullified with any preceding calling actions from the opponents.

Due to the required action of kan, this yaku cannot be combined with tenhou or chiihou.

Depending the ruleset, only ankans may be allowed to score the yakuman. Alternatively, only the dealer may be allowed to score it.

• Value: Yakuman

Shiisanpuutaa / Shiisuupuutaa

Shiisanpuutaa / Shiisanputou 「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.

Daisharin / Daichikurin / Daisuurin

Main article: Daisharin

Daisharin 「大車輪」 (Big wheels) is a closed hand with a pattern of 22334455667788 in pinzu. Likewise, Daichikurin 「大竹林」 (Bamboo forest) and Daisuurin 「大数隣」 (Numerous numbers) is achieved by using the same pattern in souzu and manzu respectively.

  • The concrete definition of daisharin may vary in each platform. Some is define it as ryanpeikou, others define it as chiitoitsu. Both definitions are identical under the general ruleset, but this does impact the available yaku if aotenjou is used.

Shousharin / Shouchikurin / Shousuurin

Shousharin 「小車輪」 is a concealed hand with seven consecutive pinzu pairs from 1 to 7, or from 3 to 9. Similarly, Shouchikurin 「小竹林」 and Shousuurin 「小数隣」 are the variants of souzu and manzu correspondingly.

  • The usage of yaku is not as common as daisharin. Usually this yaku is defined accompanying with daisharin as a weaker version.

Isshoku yonjun

Isshoku yonjun / Iisou suushun 「一色四順」 (lit. Pure quadruple sequences) is a hand containing four identical sequences in a same suit. Also known as Suuren taihou 「四連太宝」.

This yaku may be either closed only or allowed open. 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. Generally not reduced in value when open (similar to other yakuman).

• Value: Yakuman
• Examples:
  • 
  • , Ron:

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

Kamicha becomes liable for feeding the last required set.

Hyakuman goku

Hyakuman goku 「百万石」 (lit. One Million Koku) is a chinitsu hand of manzu where all of their numbers can be summed up to over a hundred. As how the yaku name indicated, a million is achieved by multiplying 100 by ten thousands, the unit of manzu.

This yaku is harder than ryuuiisou and chinroutou, as it only contains five kinds of available tiles, and they can't form any sequences.

• Value: Yakuman
• Example: , Agari:
• Trivia:
  • This yaku is derived from ryuuiisou, as it utilizes the tiles not used by ryuuiisou. It used to have a name Kouiisou 「紅一色」 (lit. All red), but it's vague due to the fact there are many other tiles that also containing red. Hence, this hand is renamed with the peacock pattern of the 1-sou.
