Zen Do Kai is a style which has developed over the past three decades, evolving from adding the principles of manymartial arts disciplines with the strong fighting tradition it has always had.

The style is traditional Japanese in nature, the foundations were originally based on the GOJO RYU style. Through a keen interest in the competitive aspect of martial arts, and to examine fighting skills and training practices that could enhance the practical abilities of the Zen Do Kai students, Bob JONES ventured to Thailand in the mid 80’s. There he saw firsthand, together with other senior Zen Do Kai instructors, the devastating ability of the Muay Thai fighters, developed over centuries of tradition. As a result of this, many of the powerful techniques of the Thai Fighters have been included into the Zen Do Kai system.

Soke Bob Jones describes the style most aptly by referring to it as a 'Purist' system. He means that Zen Do Kai is not one style but all styles. The translation for Zen Do Kai is "The Best of Everything in Progression". This means that Zen Do Kai is a dynamic system, constantly searching for ways of improvement and truth in the martial arts.
