Yakuman

Yakuman

Definition

A yakuman (役満) is a limit hand in mahjong representing the maximum possible score. It is worth 13 or more han and pays a fixed amount: 32,000 points for non-dealers or 48,000 points for the dealer (in a single yakuman). Yakuman hands are rare, difficult to achieve, and represent the pinnacle of mahjong scoring.

Detailed Explanation

The term yakuman literally means “limit hand” or “maximum hand,” and it occupies the top tier of mahjong’s scoring system. While most hands are scored by counting han (point-doubling units) and fu (base points), yakuman hands bypass this calculation entirely and award a predetermined payment instead.

Scoring Structure

A single yakuman pays:

• 32,000 points from each non-dealer player
• 48,000 points from the dealer

These payments are significantly higher than mangan (8,000/12,000) or haneman (12,000/18,000), making yakuman the ultimate goal in competitive play. Some yakuman can be scored multiple times if conditions are met, resulting in double yakuman (counted yakuman) or triple yakuman payouts.

Types of Yakuman

Yakuman hands fall into two main categories:

Closed Yakuman require a completely concealed hand:

• Kokushi Musou (thirteen orphans)
• Suuankou (four concealed triplets)
• Suuankou Tanki (four concealed triplets with single wait)

Open Yakuman can be achieved with melds:

• Daisangen (big three dragons)
• Shousuushii (little four winds)
• Daisuushii (big four winds)
• Ryuuiisou (all terminals and honors)
• Chinroutou (all terminals)
• Tsuuiisou (all honors)
• Chiitoitsu (seven pairs) - when scoring 25 han

Probability and Rarity

Yakuman hands are exceptionally rare in actual play. A typical mahjong player might see only a handful of yakuman in their lifetime of casual play. This rarity is intentional—yakuman represents such an extraordinary combination of tiles that achieving one is considered a remarkable accomplishment worthy of the maximum reward.

Usage Example

A player draws a hand containing three dragon triplets (白, 發, 中) and completes their melds. They declare daisangen yakuman and win the hand, receiving 48,000 points from the dealer and 32,000 points each from the other two players.

Another scenario: A player holds 1m, 9m, 1p, 9p, 1s, 9s, 東, 南, 西, 北, 白, 發, 中 and waits on any remaining tile to complete kokushi musou, the thirteen orphans yakuman.

Notes

In some regional rule variations, yakuman scoring may differ slightly. Tournament rules often specify which yakuman hands are permitted and how multiple yakuman are counted. Casual players should verify local conventions before play.
