Leaving a positive, lasting impression of the organization and the countries where our respective dojos are based.

Since opening its doors for the first time in 1970, Purple Dragon and Don Jitsu Ryu have spread rapidly, and thousands of members now practice the all-inclusive system in 50-plus dojos located in the Caribbean, Canada, the United States, and Europe. It is undisputedly the single largest private martial arts organization in the Caribbean, having dominated the region in terms of membership and high standards for over 30 years.

In addition to creating and evolving Don Jitsu Ryu, Don Jacob has also inspired readers worldwide and authored several books. That illustrates his combat techniques, guides to self-defense, tournament protocol, the organization’s all-encompassing value system, and many other critical themes. Flesh & Bone, one of Purple Dragon’s best-selling publications, is an incredibly useful resource to learn the steps required to obtain the highest degrees within the system.
