Kazoe Yakuman

数え役満
(かぞえやくまん)

By Kenji Tanaka · Updated

Definition

A kazoe (counted) yakuman reaches yakuman payout by sheer accumulation: 13 or more han from ordinary yaku plus dora, rather than one of the classic patterns. Some tables honor it in full; others cap counted hands at sanbaiman. Confirm the rule before you count on it.

Kazoe Yakuman

Kazoe Yakuman (数え役満, かぞえやくまん) refers to a hand that reaches 13 or more han through a combination of regular yaku, dora, and bonus tiles rather than achieving a natural yakuman pattern. The term literally means “counted yakuman”, you count up the han total until it reaches yakuman levels.

Understanding Kazoe Yakuman

How It Occurs

Kazoe yakuman happens when you stack multiple yaku and dora:

  • Base yaku: Riichi (1 han) + chinitsu (6 han) + ittsu (2 han) = 9 han
  • Bonus tiles: 3 dora + 2 uradora = 5 han
  • Total: 14 han = kazoe yakuman

While no single pattern reached yakuman level, the cumulative han count exceeds the 13-han threshold.

Rule Set Variations

Treatment of kazoe yakuman varies by rule set:

Modern/Online Rules: Most modern rule sets, including the major online clients, pay kazoe yakuman as a full yakuman; a minority of rule sets cap it at sanbaiman. Once you reach 13+ han via counting, you receive sanbaiman (24,000 points for a non-dealer, 36,000 for a dealer) but not full yakuman payment.

Traditional/Yakuman Treatment: Some rule sets treat kazoe yakuman as a full yakuman, awarding 32,000 points (non-dealer) or 48,000 (dealer), matching natural yakuman hands.

EMA Rules: The European Mahjong Association scores 13 or more han as a full yakuman, the same payment as a natural yakuman.

Comparison to Natural Yakuman

Natural yakuman: Achieved by completing specific rare patterns (kokushi musou, suuankou, daisangen). Always worth full yakuman points regardless of rule set.

Kazoe yakuman: Reached by accumulating 13+ han from combinations. May be capped at sanbaiman depending on rules.

The distinction matters: a hand with suuankou (four concealed triplets yakuman) plus dora receives full yakuman payment. The same hand value reached through chinitsu + dora might only receive sanbaiman.

Strategic Implications

Riichi + High Yaku: The most common path to kazoe yakuman is riichi plus a high-value yaku like chinitsu (6 han) or honitsu (3 han), combined with multiple dora. Uradora from riichi frequently pushes hands over the 13-han threshold.

Dora Dependency: Unlike natural yakuman which guarantee maximum points, kazoe yakuman relies heavily on dora tiles. The dora indicator significantly impacts whether your hand reaches 13 han.

Seeing Kazoe Yakuman in play

You declare riichi with a chinitsu (pure flush) hand in bamboo tiles. Your hand has pinfu (1 han), giving you: riichi (1) + chinitsu (6) + pinfu (1) = 8 han. When you win by tsumo, you add menzen tsumo (1) = 9 han. The dora indicator shows 4-bamboo, and you hold three 5-bamboo tiles (3 dora). The uradora indicator shows a 1-bamboo, and you hold one 2-bamboo (1 more uradora). Your total: 9 han from yaku + 4 han from dora/uradora = 13 han. Under sanbaiman-cap rules, this scores 24,000 points as a non-dealer (36,000 as dealer). Under yakuman-treatment rules, it scores 32,000 points (48,000 as dealer).
