Unsu (雲手), literally "cloud hands", is the most advanced kata found in the Shotokan, Shito-Ryu and IsshinShorinji Ryu karate styles and is generally taught to karateka at the 3rd to 4th Dan. It contains many intricate hand techniques, such as the ippon-nukite (one finger strike) in the opening sequence. Unsu also contains a 360-degree spinning double-kick with a double-leg take down at the same time, landing on the floor face-down before continuing. Because of this, it is a very common kata in tournaments.
The origin of Unsu is unknown, but it is of the Dragon style. It is somewhat a condensation of other katas (e.g., Bassai, Kanku, Jion, Empi, Jitte and Gankaku), hence it is essential to have mastered these before practicing Unsu. The movement, Unsu, or hands in the cloud, is used to sweep away the hands of the opponent and is said to signify the gathering clouds in a thunderstorm. It consists of 48 moves.
"Unsu" is also the title of a 2006 album by French metal band Lyzanxia.
