Talk:Japanese mahjong yaku

What is Japanese Mahjong?

I found this article through a link in the Saki (manga) article about rinshan kaihou. This article about yaku links to the Mahjong article, but not vice versa. Instead, the Mahjong article only has a sentence or two of it in its variations section. It doesn't say enough. Can you guys please just put up even an itsy-bitsy article about Japanese mahjong and link this article to it? Alphapeta (talk) 00:46, 10 August 2009 (UTC)

Well, here's some information that I was looking up, when I was trying to figure out the answer to this link's question:

Japanese Mahjong article

While this is indeed a variant to mahjong, it could be fitting for it to have its own article. KyuuA4 (Talk:キュウ) 02:29, 6 November 2009 (UTC)

Table format

May be a good idea to use tables, to reduce the extent of the contents "menu".

Seven pairs

Name	Japanese	Han value	Open/Closed
Seven pairs	(chītoitsu – 七対子, or chītoi – 七対)	2	Closed only
Description
A hand composed of seven pairs is considered a valid hand in Japanese mahjong. It is one of only two hands that are an exception to the rule requiring winning hands to have four groups and one pair (the other being thirteen orphans). It also has its own special rules for scoring. Most Japanese play with the rule that all seven pairs must be unique. In other words, if a hand contains four red dragons and five other independent pairs, the four red dragons may not be split into two pairs to make a seven pairs hand.

Improving the Tables

One way to improve the tables: having a bunch of them merged toegether as one table within the different sections. in the end, they could look like this: NFL_Top_10. The different Yaku can be separated by a colored line, instead of repeated table titles for each yaku. At this point, the tables themselves look cluttered because of it. I'll be reading into Wikipedia:Table. KyuuA4 (Talk:キュウ) 23:24, 14 February 2011 (UTC)

Those hands may be found on variations of mahjong such as GuoBiao Mahjong and Guangdong Mahjong. some include DIY japan mahjong suits that was not yet declaired verified. if verified, tell me. dont forget the japanese speaking and words! (Singaporeandy (talk) 12:58, 19 May 2011 (UTC))

The list in this article are the generally "universally" accepted hands. But yes, I would not be surprised about the existence of many home and local additions as well. KyuuA4 (Talk:キュウ) 20:19, 22 June 2011 (UTC)

Basic Rules do not belong here

This article focuses on the Yaku, not on basic rules involving "Chi", "Pon", and "Kan". KyuuA4 (Talk:キュウ) 00:06, 27 October 2011 (UTC)

Sourcing

Please don't cite other wikipedia articles. Can you get some non-wikipedia sources? bobrayner (talk) 22:57, 6 November 2011 (UTC)

I agree. Unfortunately, there are not a lot of English language sources on this topic. And I cannot read fluent Japanese. KyuuA4 (Talk:キュウ) 21:47, 7 November 2011 (UTC)

Optional Hands

Name	Japanese	Han value	Closed/Open
Revealed ready hand	ōpun rīchi – オープンリーチ, or occasionally punrī – プンリー	1 + ready hands	Closed only
This is an optional rule to rīchi. A player may reveal the needed waiting tiles when declaring ready. In doing so, an extra han is awarded to the normal ready or double ready hand. Yakuman is awarded to winning it on a discard unless the discarder already declared ready and had no choice of discarding. Some rules say the "double revealed" ready hand has four han.
Three chained triplets	sanrenkō – 三連刻	2	Closed/Open
A hand with three number triplets or quads in one suit with successive numbers. This hand is often optional.
Four chained triplets	sūrenkō – 四連刻	Limit	Closed/Open
A hand with four number triplets or quads in one suit with successive numbers. This hand is often optional.
Sequential pairs of same suit simples	dai sharin – 大車輪	Limit	Closed only
A hand of seven pairs that are sequential, the same suit, and consist of only simple tiles (numbers 2 through 8). This hand is often recognized only if it is made by a suit of pinzu (筒子; circles, coins) since the Japanese name of the hand means big wheels. Some rules do not apply yakuman to the hand, in which case it has 11 han (chin'itsu, ryanpeikō, tan'yao, and pinfu). It is noted that the hand can be recognized as a pinfu hand and always has multiple waits whatever the winning tile may be. Some of its waits lose some yaku and thus decrease the value. For example, when the hand waits 7, it also waits 1 and 4. As for other suits, the hand is called bamboo forest (大竹林, dai chikurin) for bamboos and numerous neighbours (大数隣, dai sūrin) for characters.
Eight consecutive winnings	pārenchan – 八連荘	Limit	Dealer only
A player wins eight times consecutively. The conditions of the hand depend on rules. The ninth and following winnings are often yakuman again, while some rules say the sixteenth is the next yakuman. It has nothing to do with the number of counters because the number increases when a hand is a draw. In some rules, no other yaku is necessary in the eighth winning. Some say the player must be a dealer from the first time. The player is always a dealer when the hand is accomplished. The hand is often optional.

Pulled out quote

When a winning tile of a closed hand is a discard, the meld including that discard is considered open, while the hand is still regarded as closed. If a hand is closed, the situation is called "menzenchin (門前清)" or "menzen (門前)" in Japanese.

Limiting Jargon

For the sake of this article, or any Japanese mahjong related artile, the less jargon used; the better. Specific terms may most definitely be included in the articles. But, usage of such terms must be limited. KyuuA4 (Talk:キュウ) 00:27, 4 March 2012 (UTC)

Under the Riichi section

While it is one of the most important elements of the game, indications of when a round rotates is irrelevant. That's all due to any player can declare riichi at any time (even for the purpose of a deliberate chombo). Relevance falls under the conditions of a riichi declaration itself. KyuuA4 (Talk:キュウ) 00:37, 4 March 2012 (UTC)

Game Rounds

To be clear on the meaning of a "round", this includes honba. Meaning, if the player sitting East happens to win, then the player has won East-0. The next round would then be East-1. This means, a "ren-chan" is a round. A "han-chan" is also a round. A "honba" is also a round. Obviously, as any of us who plays this game, there is a huge difference in the multiple types of "rounds". This difficultly stems on the transition from Japanese terminology to English. At the same time, as noted above, the less "jargon" used; the better. These articles have to be designed for those, who have never even heard of this game.

Standard

I think the standard yaku and local variations should be separated. 1996 Shin-Hochi rule is usually considered standard in Japan (ISBN 978-4831901187). The rule only allows 38 yaku, and following are not part of the standard.

• 流し満貫
• 三連刻
• 四連刻
• 大七星
• 大車輪
• オープン立直
• 人和
• 八連荘
• 十三不搭
• 十四不搭

I concur. And sad how difficult it is to find that book. Either way, I'll separate out a reference field to the yaku tables. KyuuA4 (Talk:キュウ) 01:21, 24 July 2013 (UTC)

Another thing, if you can create a book citation for the article, that would be great. KyuuA4 (Talk:キュウ) 01:28, 24 July 2013 (UTC)

Japanese style tiles

It'd be great to replace the Chinese tile images with Japanese style ones.

There's one right Wikipedia already; this Reddit thread mentions some other possible sources.

Error in the definition of Two sets of identical sequences?

I think there could be an error or a lack of clearness in the definition of the hand named ″Two sets of identical sequences″. In its text and illustration it seems that the hand requires two sets (of sequences) that match numerically, besides the sequences in every set themselves matching numerically. In just about any other independent source I have have checked, it seems that the pattern 789-789, 345-345 would be accepted as a legitimate occurrence, but in this article one gets the impression that both of these identical sequences must match, that is, 789-789 (in one suit), 789-789 (in another suit). The sources that voice the same opinion as this wikipedia article seem to have this article as their direct source, since just about all of them have copied the exact wording as this article.

Can someone who is well versed in Japanese mahjong please check this up, and edit accordingly?

The twin (talk) 14:00, 15 November 2018 (UTC)

I agree, the text is wrong, and such a hand would be absurdly hard to make (surely it should be worth much more if it were so). I'm fixing it. - furrykef (Talk at me) 20:13, 22 December 2019 (UTC)

Errors in the hands of sankantsu/three quads and suukantsu/four quads?

To my knowledge, the hand shown in the example for three quads is incorrect, in that the hand is already complete before drawing the north wind - it already has 4 completed melds and a pair. The north wind tiles should have already been called as a kan, with the remaining hand having 4 tiles and waiting on a fifth like so:

Three Quads / Three Kan	sankantsu – 三槓子	2	Open or Closed
called: + +
A hand consist of three quads (kan), either closed or open.

(Plus, if you consider that each quad has to be made of 3 tiles that were in the hand prior to calling the quad, and the fourth tile gets replaced by one from the dead wall, then the hand on the current page would have 14 tiles before the draw and 15 after...)

Similarly, the hand for four quads already has 4 melds and a pair before drawing the fourth 2 sou (and, similarly to above, has one too many tiles in the hand). (Because all 4 quad calls have to be made to be in tenpai for this hand, it requires a single tile wait):

Four Quads / Four Kan	sūkantsu – 四槓子	Limit	Open or Closed
called: + + +
A hand consisting of four quads, either open or closed. The abortive draw of calling four quads (by multiple players) do not apply under normal rules and play would resume otherwise until a winner is decided or a fifth quad is called.

(...this one might be running out of room horizontally though...) 2601:147:4401:4620:855A:3FD1:B3FA:1B94 (talk) 15:10, 30 August 2024 (UTC)
