Zen Do Kai is a freestyle martial art system which was developed in Australia in 1970 by Bob Jones. The style was founded by Jones and Richard Norton when they left the Japanese
Goju Kai karate dojo of Tino Ceberano.
Â Jones opened his first Zen Do Kai martial arts club at 48 Elizabeth Street, Melbourne. It was originally intended to cater for those who worked in the security industry with Jones. It
is a martial arts system which has evolved over the past three decades.
