The first public demonstration of karate in Japan was in 1917 by Funakoshi, at the Butoku-den in Kyoto. This, and subsequent demonstrations, greatly impressed many Japanese, including the Crown-Prince Hirohito, who was very enthusiastic about the Okinawan art. In 1922, having mastered two major styles of Karate, Funakoshi, then President of the Okinawa association of the Spirit of Martial Arts, was chosen to demonstrate Karate at the first National Athletic Exhibition in Tokyo. This led to the introduction of the ancient martial art to the rest of Japan.
Other masters then helped spread Karate throughout the country and the rest of the world. A general Federation of Karate Organizations was established in 1964 after Karate achieved a following abroad. This federation's main concern has been to establish unified forms, rankings, and rules of competition, and to keep contact with overseas Karate associations. Over the years, numerous schools and styles have emerged, some emphasizing the strengthening of the body, while others focused on quick movement.
