Restricted as closed only, this hand must draw at least 12 of the 13 required tile types. If a pair exists within the hand upon [[tenpai]], then naturally, the hand is waiting on the last remaining tile type not yet in the hand. This hand will become [[karaten|impossible]] if all four of any of the tile types are no longer available. | Restricted as closed only, this hand must draw at least 12 of the 13 required tile types.

In order to for this hand to be reasonable, your [[haipai|starting hand]] should contain many terminals/honors, generally 9 or more. This gives the option to call [[Tochuu_ryuukyoku#Kyuushu_kyuuhai|kyuushu kyuuhai]], if no tiles have been called by others, and if the ruleset allows this [[abortive draw]]. Declining (or not having) this option puts the hand on the path to form the yakuman. | |||

Kokushi musou juusan menmachi is very rare. Out of all random tile draws that result in tenpai for kokushi, the chance of naturally drawing all 13 tiles without a single duplicate is approximately one in 9500 (~0.0106%). The only "consistent" way to achieve the double yakuman is to complete kokushi via tsumo, but discard the pair and hope to complete the hand while in furiten. | Kokushi musou juusan menmachi is very rare.
