Fudoshin Kenpo Jujitsu

Fudoshin Kenpo Jujitsu

     Fudoshin Kenpo Jujitsu is a martial art and self-defense system that focuses equally on stand-up fighting and ground fighting. The system was derived from principles & techniques taken from Military Combatives, American Kenpo Karate, Brazilian Jiu-jitsu, Jeet Kun Do, and more. [Train ONLINE]

    It’s a system that focuses first on the primal instinctive reactions of human beings under duress and is then followed by scientific principles of techniques.

    Philosophically, the system focuses on Fudoshin (spirit of immovable mind & heart) principles and Bushido (way of the warrior) principles.

   The system was compiled and formalized in 2002 by Brian K. Allen, a Military Policeman (US Army) and Executive Protection Agent (bodyguard).  Allen, a black belt trained and certified by senior-level soldiers in the US Military, had been removing or making changes to techniques that he had been taught after each violent encounter he survived.  He was doing this with the help of the same military mentors that had trained him.

     During Operation Enduring Freedom, Allen’s mentors were killed.  Due to the nature of their work, their names have been redacted from all of Allen’s martial art notes & certificates.  In addition to the huge emotional loss, this left Allen with a pile of notes and no one to guide him in martial arts.

     Knowing he was going to have to keep learning from people more experienced than he was, he sought guidance and membership in two different organizations… one being the ‘United States Martial Arts Association’ and the other the ‘International Kenpo Karate Federation’.  In late 2006, Allen stated on his Bodyguard Blog that between the two organizations, there were plenty of people who could ‘beat him up’ along with many, many great human beings to learn the “wonderful aspects of the martial arts philosophies” from.


     According to information found on the United States Martial Art Association website in 2002, the original name for the system was Allen’s Kenpo Jujitsu. Records show that Allen formally changed the name to Fudoshin Kenpo Jujitsu in 2010.


     Allen and his mentors developed the system by eliminating techniques they couldn’t actually pull off during violent encounters.  A few of the reasons they found some things just wouldn’t work, included the combat boots & equipment they were wearing, the adrenaline rush they were experiencing, sweat/blood that made things slippery, the rage factor of their attacker(s), etc.

     Allen openly states that his mentors learned how to ‘trim the fat’ off their martial art techniques, by studying combatives “outside of their traditional systems”.  This included studying from instructors such as Tony Blauer, Richard Dimitri, Paul Vunak, and more.  While he openly gives credit to those instructors, Allen also gives credit to martial artists such as Ed Parker Sr., Rorian & Rickson Gracie, and Bruce Lee not only for their amazing physical skill sets, but for their “teaching genius”.

     Note: Brian K. Allen holds a 7th Dan in Fudoshin Kenpo Jujitsu, a 6th Dan in Bushido Kenpo, a Green Belt in Ninjutsu (IBDA), and a Master Instructor certification.  The US Grandmasters Council, USMA & IKKF recognize his rankings. (Apr 2017)  In preparation for his senior ranking applications, Brian Allen began studying Ninjutsu under Shihan Richard Van Donk in 2016. He stated that putting on a white belt and learning the traditional ways of ancient warriors will make him a better role model and life skills teacher for his students. In 2023, at the age of 50, Brian Allen enrolled in a Gracie Barra BJJ academy.  At the time of this update, he states he is a white belt in their system and loves the fact that he’s able to study & learn while getting beat up.


     Fudoshin Kenpo Jujitsu is still in its’ infancy and is not well known outside a few specific circles.  In 2010, classes started popping up to non-military students in Arizona. In 2013 a school in Montana began teaching the art. (As of 2020, the Montana school is not operating.)

Style of Fighting

     Fudoshin Kenpo Jujitsu teaches that, although half of their training involves ground fighting, you NEVER want to go to the ground in a street fight.  If it happens, ok… deal with it and get up.  However, due to unknown weapons, accomplices, and environmental concerns… staying on your feet is a priority.

     A practitioner of Fudoshin Kenpo Jujitsu will do whatever it takes to get off the ground if attacked, even if pinching, biting, or ripping and tearing at the eyes & face are necessary.

     That being said, there are two complete curriculums taught at a Fudoshin Kenpo Jujitsu School.  (1) Fudoshin Kenpo Jujitsu & (2) Jujitsu.  The Jujitsu is extracted from the FKJ for those students who want to focus completely on that aspect of the martial arts.

     Physicality is also emphasized.  FKJ takes a realistic look at athletes such as college & pro football players in addition to college and Olympic wrestlers.  In 2007, Allen wrote in his blog, “If someone tells you size and strength don’t matter in a fight, they’re mistaken.  Now, size and strength don’t ALWAYS determine the ‘winner’ but they DO always matter.  Oh, and they NORMALLY determine the winner in a street fight or assault.”

The Gi / Kimono

Practitioners wear either a heavyweight Kenpo Karate style Gi or a heavy Jiu-Jitsu / Judo Gi.


      The ranking system at a Fudoshin Kenpo Jujitsu school differs depending on the focus the student chooses.  Both the Fudoshin Kenpo Jujitsu & Jujitsu curriculums award a practitioner different colored belts to signify increasing levels of technical knowledge and practical skill.  (see below)

     The amount of time it takes to achieve the rank of black belt varies between the individual but the approximate time frame is 4 years (per curriculum chosen) with a consistent training schedule of 3 times per week.
