Aiki Goshin JuJutsu

About PMA Aiki Goshin JuJutsu

The style of JuJutsu taught at PMA is a traditional Japanese style, not Brazilian.  We teach JuJutsu as a method of self-defense, not a style for competition.  While grappling (ground-fighting) is part of what we do, it is not our primary focus.  We try to teach the student how to control the situation with a minimal amount of effort on their part, giving them the ability to walk away from the encounter.  It is our desire to instill knowledge to the student.  No attack will be clean and pretty.  It will not be the same as a training partner's attack.  Therefore, the knowledge of how a technique works, the mechanics, is crucial. That knowledge allows the defender to adapt and respond.

JuJutsu has not had a neat, organized history as many other martial arts have. It is easier to trace a martial art when there is a single source from which it began. It is more difficult to trace the roots that form the base of an art such as JuJutsu.

The practice of JuJutsu can be traced back in history more than 2,500 years. JuJutsu, translates as "Gentle Art", and developed from many individual teachings that either originated in Japan or found their way to Japan from other Asian countries. The first dated mention of JuJutsu was during the period 772-481 B.C. when open-handed techniques were used in China. There is evidence that empty-handed techniques were in use during the Heian period (A.D. 794-1185) in Japan, but in conjunction with weapons training for the samurai.

Stated simply, JuJutsu is the "gentle art" of self defense. This is a very simple definition for a very complicated art. JuJutsu is a series or combination of techniques. There are perhaps 30 to 50 basic moves in JuJutsu, however, it is the combinations and variations of the basic moves that make the art so complex and almost infinite in its variety of moves. Jujutsu can be separated into three general areas. Taught separately they have other names. First there are the throwing and leverage techniques (Judo). Second are the striking and hitting techniques (Karate). Third are the nerves, or pressure points, and use of attacker momentum (Aikido).

JuJutsu made its way into the United States in the early 20th century. Although there are historical accounts that President Theodore Roosevelt practiced JuJutsu, it may actually have been Judo. A significant influx of the art was first felt in Hawaii and on the Pacific Coast of the United States between 1920 and 1940.

Partner Training

Due to the nature of JuJutsu techniques, it is virtually impossible to learn and practice without a partner. Partners must be willing to work together and, above all else, trust each other. Basic to this trust and willingness to learn are the elements of both courtesy and caution.

Attacker Responsibility

Attacks should never be overly aggressive. Align your attacks with the skill level of the defender. As the defenders proficiency grows, then the attacks may become more aggressive. In this way both skill and confidence will grow. It is equally important that an attacker should not excessively resist and attack or experiment how high his threshold of pain is. There is a very fine line between pain and injury. A slight increase in pressure can quickly change pain to injury. An attacker should always "go" with the defenders lock or throw. If excessive pain is created with a movement, the attacker signals the defender by tapping the mat, your own body, or the defenders body with the palm of your hand. This will signal the defender to immediately release the hold.

Last, it is not the place of the attacker to perform any type of counter technique on the defender. This action will often result in injury to one or both of the students.

Defender Responsibilities

The defender must always be considerate of the attacker. The art of JuJutsu was designed to quickly cause injury to an attacker and thus neutralize that attacker. Usually this injury is in the form of a dislocated joint or a broken limb. The most common result is a linear fracture, which unlike a clean break, splits the bone lengthwise. This result is due to excessive torque on the weaken joint or limb. All techniques should be done slowly and smoothly in order to insure both proper motion and to eliminate the chance of injury to the attacker.


You and your partner must assume a learning attitude during training. You must both be willing to help each other. As beginners, the cooperation is essential. As skill level grows higher, the attacks may become more aggressive. As the attacker, always "go with the technique". However, when "going with the technique", do not just fall down to make the partner happy. this type of action prevents proper learning. As students and training partners, your desires to learn the art effectively must be sincere.

Circle Theory of Movement

Now all this is good and well, but what does it actually mean and more importantly, how does this theory apply to a defense situation? If we look at the first phase of "properly redirecting momentum", this supplies an important starting point. How is momentum redirected? it is of utmost importance that the attackers momentum should not be taken from straight on. It should be deflected. By the use of a side step, circle based block, etc., the attackers force may be used against him. In this fashion, even the strongest, and most aggressive attacker may be neutralized. it is said that if a person has a power of 10 and engages in combat with a person who possesses the power of 6, then in a muscle confrontation the stronger will win. However in the redirection of power, the person with the power of 6 simply adds 2 of his 6 to the power of 10 being exerted by his attacker during the attack. Due to this slight addition of power to the attackers momentum, the attacker is then caused to be off balance and extremely vulnerable to counter attack.

Once the attack has been deflected, then the circle theory comes into play. When a movement is performed in a circular fashion, the generation of power remains at a constant during the entire movement thus making the chance for a counter very difficult. As long as the technique continues to flow and does not make sharp linear corners, the techniques will be effective. The defender must always make himself the center of the circle force and attacker revolve around him.

In the application of the "circle theory", the three plains and two types of circles should be understood. They are:

The first plane is the horizontal plane and it flows in a circle parallel to the ground and is usually a large circle. It makes full use of both attacker momentum and deflection. This type of circle is best suited for use is attacker redirecting and attacker movement.

The second circular plane is a vertical plane. This particular plane flows perpendicular to the ground. this plane is well suited for the execution of over-the-hip or shoulder throwing techniques. It is well adapted for taking full advantage of high or over head types of attacks.

The third and final plane is the diagonal plane. The direction of this plane in relation to the ground is self explanatory. It is the most versatile and easily applied of all the planes. The range of defense of the diagonal plane ranges from escape techniques to devastating projection throws.

It is important to remember that once a certain plane is established, it must not be sharply changed to another plane. Although all the planes can be combined to function together, (this is what evolves into combinations and attacker control), they must intertwine smoothly with one another without a break in speed or momentum. A properly applied combination usually is in the form of a figure 8 or a spiral pattern.

Once the defense plane is established, then the next step is to decide what type of circle is necessary, and open or closed circle.

The first type of circle is the open circle. An open circle is one that the defender does not give a definite end to. This type of circle is best used in throwing and projections. Through an appropriate extension of the attackers momentum and force, the defender may easily deflect the attack from the intended target and send the attacker virtually "Sailing through the air".

The second type of circle is the closed circle. This type of circle is typical to joint locks and immobilization in that the attacker is controlled all the way to the end of the circle. The  objective of the defender in this type of circle is to channel the attackers force back to its source thus making the attacker the target of his own attack. In this way all the effort that the attacker puts into the attack will be used directly against him.

In understanding the "theory of circular movement" the defenders body should become a spinning top deflecting anything that comes in contact with it. The circles should always be positive, smooth , and flowing no matter what force appears and attempts to interfere. As the student becomes able to apply this theory to a typical attack-defense application, then a true insight into flexible and flowing power over muscular brute force will naturally come out. At this time the student will be well on the path of mastering JuJutsu.
