Mi Yama Ryu

MiYama Ryu 

Miyama Ryu was developed by Shinan Antonio Pereria for real-world self-defense on the hard streets of the South Bronx NY and passed on to hundreds of students worldwide.

He passed it on to  Kenneth Winthrop who was the 5th person to ever be promoted to black belt by Shinan Pereria. He was given his black belt in 1965 long before many of the people you see today training.

It should be noted that Shinan Pereria personally asked Kenneth Winthrop to bring Mi Yama Ryu JuJutsu to the west coast. Unfortunately at the time, he was asked Kenneth Winthrop did not have the resources to make that happen. Now with Raven Self Defense Academy as the Mi Yama Ryu Kempo JuJutsu Kai  & FASST Krav Maga headquarters, he can now honor the request of his teacher. Long Live MI YAMA RYU!

A Brief History of Miyama Ryu

Combat Jujutsu in WWII

The origins of combat jujutsu stretch back over half a century. In 1942 Antonio Pereira, a young American soldier was participating in a hand-to-hand demonstration. When ordered to punch one of the instructors in the face, he complied, only to find himself whipped around into a chokehold.

During World War II, Pereira learned as much as he could about specialized combat methods. He continued to experiment and practice with the techniques, refining them sometimes under life and death situations.

A Warriors Quest for the Ultimate Martial Art

After the war, his warrior's quest for additional knowledge took him to many schools in search of martial prowess. In 1950 he began a formal study of judo with the Lefcoker brothers. He began to research how victims of crime were attacked and devise methods of practical defense.

Responses Against Real Street Attacks

In 1960 he opened a martial arts school on Tremont Avenue, in the South Bronx, New York. He called his rough-and-tumble method of fighting Combato. But the puzzle was still not complete.

In 1962 he embarked on a journey to Japan. His plan was to study from the source, and perhaps to gain a better sense of the martial principles.

Training in Japan with the World's best

As he observed the practice at the Aiki Kai (Aikido school), Pereira recognized similarities to what he had been doing all along. Pereira set out to learn more refined methods.

His fierce resolve and dedication won him many honors. Among them were a teaching certificate from O-Sensei Ueshiba and a Ni Dan in Judo from the Kodokan (the birthplace of Judo).

Pereira returned to the United States and resumed teaching at the Tremont School. Periera would later earn a San Mokuroku in Sosuishitsu Ryu Jujutsu, a Koryu (Jujutsu), from the then-current Headmaster Professor Saitama.

Samurai Self-Defense Refined For You

Knowing that the Western lifestyle and philosophy differ from the Eastern, he adapted the physical techniques and mindset of the Samurai Warrior to the culture of the dangerous streets of the modern, urban South Bronx.

In effect, he created one of the few combat methods suited for today's streets. He combined elements of Judo, Aikido, Koryu Jujutsu, Karate, Boxing, and the less organized, but no less effective element of Western street-style fighting.

In 1964 he formalized the name of his eclectic method Miyama Ryu Jujutsu, which means School of the Three Mountains in English, or Tremont in French. This was the avenue on which the school was located.

Learn From The Source

Kenneth Winthrop began his training in 1957 while stationed at F.E. Warren AFB where he trained Judo. After leaving the military he looked to continue his study of martial arts. It was at this time in 1962 that he began training in Mi Yama Ryu JuJutsu directly under Shinan Antonio Pereira, and in 1965 he was awarded his 1st-degree black belt.  Decades later Dai Hanshi  Kenneth Winthrop is the oldest living Black Belt directly under Shinan Pereira still actively teaching the original Mi Yama Ryu JuJutsu system, now called Mi Yama Ryu Kempo JuJutsu. Recently Dai Hanshi Ken and Hanshi Rave have added the element of FASST Krav Maga into the curriculum of Miyama Ryu. This is something that Dai Hanshi Ken feels his teacher Shinan Antonio Pereira would have done himself if he would have been alive today. 

Honoring The Grandmaster

Shinan Pereira died in 1999. The original Bronx, NY school had closed after his death but the art has been kept alive by one of Shinan's original black belt students - Dai Hanshi Kenneth Winthrop, who is continuing the legacy of his teacher as requested through spreading Mi Yama Ryu JuJutsu. 

The Mi Yama Ryu JuJutsu Legacy Continues

Dai Hanshi Winthrop has had the opportunity to share Mi Yama Ryu JuJutsu with the Las Vegas Detention and Enforcement Department, LVMPD, DOD, and the USAF using Mi Yama Ryu principles to develop an effective defensive tactics program. He created his own unique method of sharing Mi Yama Ryu based on the original system taught to him. 

In 2020 following in his teacher's footsteps with the help and encouragement of  O'Sensei Raven Cain,  Dai Hanshi Kenneth Winthrop formed Mi Yama Ryu Kempo JuJutsu

Menkyo Kaiden

Dai Hanshi Winthrop has passed the full transmission of MiYama Ryu Kempo JuJutsu to Raven Cain awarding him the  Menkyo Kaiden  (full transmission) license and proclaiming him as the inheritor of Mi Yama Ryu Kempo JuJutsu in 2020.  With the blessing of  Dai Hanshi Winthrop, O'Sensei Raven Cain will keep the tradition alive.
