Unsū

Unsu (雲手), literally "cloud hands", is the most advanced kata found in the Shotokan, Shito-Ryu and 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.
