Restricted as closed only, this hand must draw at least 12 of the 13 tile types, among the honors and terminals.  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. In turn, this hand will be deemed [[karaten|impossible for completion]], when all 4 of any of the tile types are no longer available.  Yet, if a player manages to develop the 13 wait variety, then this hand greatly increases its chances of completion, needing to simply pair any of the 13 types.

Reasonable development of this hand begins with a dealt set of tiles that gives a player the option to call [[Tochuu_ryuukyoku#Kyuushuu_kyuuhai|kyuushuu kyuuhai]].  Declining this option puts the hand on the path to form this yakuman.

On average, a hand ending in [[exhaustive draw]] ends with roughly 16-19 tiles discarded per player, pending any tile calls.  Therefore, every player has that many tile draws to work with.  For example, if a hand starts with 9 tiles for the yakuman, then it requires 4 [[shanten|tile draws]] searching for specific tiles.  Usually, barring unusual circumstances, those tile draws are nonconsecutive.  If anything, a number of tile draws will be required to even attain tenpai.  With that said, the decision to form a kokushi musou must be a decisive one at the [[haipai|very beginning of the hand]].
