Karate is a self-defence system that combines fast, direct techniques with great power, generated through body mechanics.Generally speaking, the aim of a karateka when forced to fight is to subdue an opponent with one decisive move.At the turn of the 20th century, Anko Itosu gained permission to end the shroud of secrecy for those who wanted to learn martial arts and began teaching Te in Okinawan schools. This led to further expansion by one of Itosu’s students, Sensei Gichin Funakoshi, who introduced the art to Japan in 1922.
