In a bold declaration that’s sending ripples through the martial arts community, Dr. Rhadi Ferguson—a seventh-degree judo black belt, fifth-degree BJJ practitioner and 2004 Olympian—has made an uncompromising statement about the relationship between Brazilian Jiu-Jitsu and judo.
“Brazilian Jiu-Jitsu is Judo, period,”
Ferguson states with characteristic directness.
“Not kind of, not inspired by, it is Judo, just under a different set of rules.”
The accomplished martial artist, who has competed at the highest levels in both disciplines, draws a crucial distinction that he believes has been lost in modern discourse.
“Let’s stop confusing the sport with the art. The sports are different, the arts are the same.”
Ferguson‘s argument centers on a historical fact that he says many practitioners have forgotten or never learned. When Mitsuyo Maeda arrived in Brazil over a century ago, he didn’t bring an experimental system or modified techniques.
“What he brought was Kodokan Judo with him, the complete system created by Jigoro Kano,”
Ferguson explains.
“He didn’t bring a watered-down version, he didn’t bring an experimental version, he didn’t bring any all-offs, he brought Judo.”
According to Ferguson, what emerged in Brazil wasn’t a new martial art but a strategic emphasis on one particular aspect of the original system.
“What the people in Brazil, the Gracie family and others, modified and later spread across the world was Newaza-focused Judo, not some separate martial art. They simply emphasized the study of groundwork and allowed it to evolve through the sport.”
The doctor methodically breaks down techniques that BJJ practitioners might consider uniquely theirs.
“Card retention, Judo. Triangle, Senkaku, Judo. Mount, side control, back control, all found in Judo, Koshin Judo, for decades before BJJ ever began.”
His perspective carries particular weight given his unique position in both worlds. As someone who holds high ranks in both arts and teaches them daily, Ferguson offers an insider’s view that challenges conventional wisdom. He points to other martial arts that have maintained their lineage connections, noting how karate styles like Shotokan and Goju-Ryu keep their origins in their names.
“The only thing that’s changed is the rulebook,”
Ferguson insists.
“Brazilian Jiu-Jitsu is Judo, built upon Judo mechanics, Judo mindset, Judo principles and Judo philosophy. The sport might look different but the roots run deep and are identical.”
The martial arts veteran acknowledges that both systems have evolved but he argues this evolution occurred due to rule changes rather than fundamental differences in the underlying art. This evolution has created distinct sporting expressions while the foundational principles remain unchanged.
Ferguson‘s message extends beyond academic debate. He sees this as a matter of respecting lineage and understanding history. His call for recognition isn’t about diminishing BJJ’s achievements or innovations but about acknowledging the true source of these developments.
The response to Ferguson‘s statements has been mixed with some practitioners embracing the historical perspective while others argue that significant differences have emerged over time. Some point to technical variations and training methodologies that have diverged substantially from traditional judo practice.
However, Ferguson remains steadfast in his position, backed by his extensive experience in both disciplines. His message to BJJ practitioners is clear: understanding and respecting these roots doesn’t diminish the art—it enriches it.
“If you study, if you read, you will agree,”
Ferguson concludes.
“If you disagree, you got more reading to do.”
Ferguson‘s voice adds significant weight to discussions about lineage, evolution and the true nature of these grappling systems. Whether practitioners agree or disagree with his assessment, his call for deeper understanding of martial arts history resonates with the importance of honoring the foundations upon which modern systems are built.
