Counted yakuman

A hand that reaches 13 or more han through sheer accumulation is scored as a yakuman.

Value Yakuman (closed hands only)
How often very rare

Counted yakuman hands are assembled, not found. The realistic route runs through a full flush or half flush loaded with dora : riichi adds ura dora chances, each kan adds an indicator, and red fives count where the table uses them. Once a 6-han base meets a deep dora pocket, the total climbs fast. The ladder is on the score table — 11 and 12 han make a sanbaiman, and from 13 the hand is scored as a yakuman.

The counting trips people up in two ways. First, dora are not yaku: a hand carrying a pile of dora but no yaku cannot win at all, so the base must come from real yaku — see why every hand needs one. Second, the threshold is not universal. Some rulesets cap accumulated hands at sanbaiman no matter how high the count climbs, so if a monster hand is forming, confirm which rule your table plays before you count your payout.
