Kazoe yakuman
Kazoe yakuman is a special class of yakuman, where hands are composed of regular yaku. Yakuman in this fashion is achieved with the accumulation of 13 han or more via a mixed combination of regular yaku and/or dora.
If the hand happens to be a regular yakuman, calculation of han is skipped, even if there were 13 or more. It is not possible to combine kazoe yakuman and regular yakuman to score multiple yakuman with one hand.
Different kazoe combinations
The sheer nature of kazoe allows different possibilities.
Chinitsu based
With chinitsu already at 6 han while closed, this hand is already almost half-way to the needed 13 han for kazoe yakuman. Naturally, other yaku and/or dora are necessary in order to increase the han count to 13. Nevertheless, chinitsu is a common yaku for this combination.
Example:
Dora based
Large numbers of dora can easily push hands beyond the 13 han limit. This is particularly true with kan dora and ura dora (with kan ura dora).
Examples:
- Riichi with 12+ dora
Without dora
A few possible kazoe yakuman combinations do not require dora to achieve 13 han.
- Chinitsu with ryanpeiko, tanyao, pinfu, riichi, and tsumo.
- Shousangen with toi toi, san ankou, honrotou, honitsu, and san kantsu
