Akai Yama Ryu Ju-Jutsu


Raven Self Defense Academy is on a mission of preserving one of the most realistic JuJutsu systems ever devised 

Akai Yama-Ryu JuJutsu. 

Akai Yama Ryu is based on Mi Yama Ryu JuJutsu as created by Shinan Antonio Pereira.  Grandmaster Winthrop through inspiration from his teacher developed physical techniques and the mind set of the Samurai Warrior to the culture of the dangerous streets of the modern, urban America. In effect, he created one of the few combat methods suited for today's streets. He combined elements of  Mi Yama Ryu JuJutsu, Shotokan Karate, Hapkido, Kuk Sool and the less organized, but no less effective element of Western street-style fighting.

Since 1965 Akai Yama Ryu  Jujutsu has taught thousands of civilians and has been used in the design of courses for United States Federal agents, taught at police and law enforcement academies across the world.

Akai yama-Ryu  Ju-Jutsu revolves around the concept of the “Omaza” or complete technique. An attack is met head on with either an aggressive block or an evasion. This is followed by an unbalancing technique such as a strike to the vital area; then a major punishing technique is employed. This could be a joint lock, wrist turn, choke hold, or a projection. Now stunned, he is struck again on the ground. He is then immobilized with a joint lock.

Akai Yama-Ryu JuJutsu workouts are spirited and aggressive, yet there are no injuries. Practice sessions are conducted as safe as possible, while maintaining realism.  

Grandmaster Kenneth Winthrop (10th Degree Red Belt) and the founder of Akai Yama Ryu JuJutsu  Received his black belt in 1965 and was the 5th person to ever earn a black belt in Mi Yama-Ryu JuJutsu directly under the founder Shinan Antonio Pereira.  Shinan Pereira passed away in 1999. 

Now at 80 years old Grandmaster Winthrop wants to honor his teacher by keeping the spirit of Mi Yama Ryu JuJutsu alive through  Akai Yama Ryu JuJutsu.  


JuJutsu, Jujitsu, Jiujitsu, Juijitsu and Jiujutsu: What's the difference?

None. When the art of Jujutsu was translated from the Japanese language into the Romanized languages like English, there was no established way of spelling it correctly.

Also depending on the dialect of the Japanese speaker it may have sounded different to the person doing the translation. Different standards have been adopted over time that is why there are many different spellings.

There are other names for Jujutsu including Aiki jutsu, Aiki jujutsu, Yawara, and Taijutsu. And Jujutsu is a foundation art for non-Japanese arts like Hapkido.

Of course there are many styles of Jujutsu including modern styles like Gracie, Small Circle, Danzan and Budoshin Jujutsu.

Why is Jujutsu called a parent art?

The founder of Aikido and Judo studied Jujutsu. Additionally it the parent art of Kempo Karate, and other Karate styles such as Wado Ryu Karate.

How old is Jujutsu?

No one knows for sure. We only know that it was systematized by the Samurai warrior as early as the mid 15th century.

The Samurai was trained in many weapons and most modern martial artists are aware of the Samurai sword.

Why did Shinan Pereira formulate the Miyama Ryu and not teach the Japanese martial arts directly as self-defense?

Miyama Ryu was created as a response to attacks as they occurred to people on urban streets.

He felt that the Japanese arts in their classical forms were based on different attacking formats and therefore did not provide immediate answers for modern self defense.

Why is Akai yama Ryu called Combat Jujutsu?

When we say combat we mean defense against attacks as they would actually occur on the streets. Some Jujutsu styles have perpetuated the myth that fighting someone for 45 minutes on the ground is self-defense.

Of course your own common sense would tell you that rolling around on the streets of New York or any major city for 45 minutes with an armed attacker or multiple attackers would mean certain death.

Are there any weapons training in Akai Yama Ryu?

The night stick, collapsible baton (Tokusho Keibo), Walking stick (Tanjo). The Founder also encouraged training in the classical arts of Iaido, Kendo, Kenjutsu and Jo (also called Jodo and Jojutsu). Additionally knife fighting (tanto) was also taught. Based on the hand-to-hand combat training Shinan Pereira learned in World War II.

Is Kata used in Akai Yama Ryu Training?

Yes two-man Kata is used. Also Miyama Ryu practitioners study Kodokan Kata and Kata from other Koryu styles such as Sosuishi (Sosuishitsu) Ryu.

What's the difference between Akai Yama Ryu and Brazilian Jujutsu?

Akai Yama Ryu is not a Gladiator type sport. Akai Yama Ryu was designed so a normal person could learn how to defend themselves against violent criminals. These attacks include defenses against weapons and multiple attackers, which are not addressed in sport type martial arts. The training necessary to defend yourself is different from preparing for a sporting competition.
