Kusanku, also calle Kankudai (観空大) (translated as gazing heavenward, viewing the sky, or contemplating the sky), is an open hand karate kata that is studied by many practitioners of Okinawan and Japanese karate. In many karate styles, there are two versions of the kata - Kusanku sho and Kusanku dai. The name Kusanku/Kosokun, is used in Okinawan systems of karate, and refers to a person by the name of Kusanku, a Chinese diplomat from Fukien who is believed to have traveled to Okinawa to teach his system of fighting. In Japanese systems of karate, the kata is known as Kanku after it was renamed in the 1930s by Funakoshi Gichin. Due to its difficulty, this kata is often reserved for advanced students. One of its distinguishing features is the jump, which incorporates two kicks.
