Shidokan is a hybrid full-contact martial art - consisting of karate, kickboxing and grappling - and is also known as the "triathlon of martial arts". The World Championships in Chicago (USA) under the direction of Yoshimura Eddie Shihan brought Angerer Renshi in 1995 for the first time in contact with the Shidokan and already two years later, the German was appointed by Soeno Kancho as Branch President for Germany on the intercession of Yoshimura Shihan. 

The World Federation headed by Soeno Kancho, is based in Japan and works closely with the German branch. Angerer Renshi has already hosted quite a few European and World Shidokan Championships in Germany over the past decades and is known worldwide as the coach of numerous internationally successful athletes.
