Kazoe Yakuman
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).

役満
A yakuman is a limit hand, the ceiling of the scoring ladder: a fixed 32,000 points (48,000 from the dealer), regardless of fu or dora. They come from a short list of extreme patterns (kokushi musou, suuankou, daisangen, the wind and honor hands) rather than accumulation, though 13 counted han reaches kazoe yakuman in most rules, and some patterns score double in their hardest forms. Spotting a live yakuman path early is one of the few good reasons to abandon normal efficiency.
Han
翻
Han are the doubling units that set a hand's value. Every yaku carries a fixed han count, each dora adds one, and they stack: riichi plus tsumo plus tanyao plus two dora makes 5. Each han roughly doubles the base score until the named tiers cap it (mangan at 5, haneman at 6-7, baiman at 8-10, sanbaiman at 11-12, yakuman at 13 or a limit pattern). Below mangan, han pairs with fu for the exact payout.
Dora
ドラ
Dora are bonus tiles worth one han each in a winning hand, without ever counting as a yaku. One indicator flips at the start of each hand; the dora is the next tile up from it, wrapping 9 to 1 and cycling within winds and within dragons. Red fives count in most modern rules, kans flip extra indicators, and riichi wins reveal the hidden ura dora underneath. Dora cannot make a hand legal on their own, but they routinely turn a cheap hand into a mangan, which is why counting the live dora is part of reading any table.
