Our Mission

Purple Dragon, an international leader in the martial arts industry, is committed to providing the highest standard of self-defense and fitness systems to all its members. The dojos’ respective leaders – all certified in Don Jitsu Ryu – impart the most practical and all-inclusive instructions through Purple Dragon’s many innovative and exclusive programs. Purple Dragon is intent on maintaining its reputation of integrity as it continually expands its global reach.


Purple Dragon’s mantra, “Don Jitsu Ryu is not just a style, but a lifestyle,” is no cliché. Our certified instructors encourage students to live up to the ideals of Don Jitsu Ryu by embracing a holistic standard of living, promoting health and wellness, and the appropriate application of the system.

All instructors certified in Don Jitsu Ryu apply this to each training session in keeping with Purple Dragon’s formidable reputation.

With 50+ years of existence, we continuously strive to improve our standards to benefit all members worldwide and, by extension, the respective communities we serve.

Having visited six out of seven continents and over 70 countries, Purple Dragon’s Don Jitsu Ryu, led by founder Grandmaster Professor Don Jacob, has inspired hundreds of thousands of martial arts enthusiasts worldwide through workshops, lectures, presentations, tournaments, and grading events. 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. Thousands of members now practice the all-inclusive system in 50-plus dojos 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 since its existence.

In addition to creating and evolving Don Jitsu Ryu, Grandmaster Professor Don Jacob has 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 a beneficial resource for learning the steps required to obtain the highest degrees within the system.

The various titles and Purple Dragon apparel, DVDs, merchandise, and martial arts equipment are available at our online store: or at our supply store Black Belt Martial Arts Supplies, located at #44 Henry St, Hadeed Centre Mall, Port-of-Spain, Trinidad.
