Miyama-ryu Combat Ju-jutsu  has come a long way after Shihan Pereira pass away in 1999 to become the only international leading authority worldwide in teaching and certifying in the art of Miyama-ryu Combat Ju-jutsu, under the responsibility of three Dai-Shihan's D'Arcy Rahming, Dr. William Duke and Robert Aviles Sr. and the International Executive Board lead by Shihan Omar Echavaria chairman, Shihan Julio Cordero vice chairman, Shihan Candy Soto secretary, Shihan Soraya Dujuarric assist. secretary, Shihan Samuel Bisono, Shihan agustin Palau, Shihan   Dan  Wagner, Osensei Luis Soto, Osensei Dr. John Rodger and Sensei Frank Pena.  

 Founded and refined on the street of the South Bronx. Miyama-ryu Ju-jutsu is a martial art that utilizes the techniques and principles of classical Ju-jutsu against modern street attacks.

Miyama-Ryu Combat Ju-jutsu  is a direct descendant of classical Ju-jutsu, which is the parent art of Aikido, Judo and some styles of Karate.  The Miyama-Ryu Combat Ju-jutsu practice is base on the "Bushido Code", humility, courtesy, loyalty, honor, bravery, justice, benevolence and honesty.

A firce man named Antonio Pereira called this method Miyama-ryu, which means the School of the Three Mountain, and he assumed the title of Shinan (The Originator).

Shinan Pereira died in 1999 and with him the era of Tremont as the center of Miyama Ryu came to an end.  

Not only is Miyama Ryu Combat Jujutsu taught to civilians, but it has been used in the design of courses for United States Federal agents, taught at police and law enforcement academies across the world and is still being refined today by three   Dai-Shihan's D'Arcy Rahming, Dr. William Duke and Robert Aviles Sr. and the International Executive Committee lead by Shihan Omar Echavarria chairman.
