Kokushi musou, also simply known as kokushi, is one of the standard yakuman hands. This hand consists of one of each terminal tiles from each suit and one of each honor tiles, where at least one pair of any of the tiles must be included. This hand is one of the two exceptions of the "four melds and one pair" rule of forming a hand, where the other exception is the chii toitsu. This hand is closed only.

Usage

The word kokushi can be translated as "distinguished citizen"; the word musou is often translated as "peerless". Don't butcher the two words and write something like "Koku shimusou", as that would be awkward.
