Stamford Judo

Schedule of our

We will practise the newaza and takedowns of Brazilian JiuJitsu, Jujutsu, and Judo.  Of particular interest will be the techniques of the famous coaches and former Olympic and World Champions, Isao Okano and T. Kashiwazaki.  The Head Instructor, Chris Angle, has had the opportunity to experience free practise and be present at clinics with these world famous coaches.

To the right is a summary of the historical relationship between jujutsu, jiujitsu, and judo mostly taken from the online encyclopedia, Wikipedia.

Below are some photographs of Jujutsu and Judo (newaza) practise at our dojo starting with the coaches:

And speaking of strangulation, Garth is  attempting to choke out Head Coach Angle!  Good Luck, Garth!

It appears that we are all brawn and no brain, but, nay, proof is here above:  Saeid, who in downtown Stamford plays chess against four opponents at once...blindfolded!, is holding down Garth.  We wonder if Saeid can play against multiple chess opponents while holding down judo/jujutsi guys!

And here Saied is again with another UJK.

HISTORY OF JUJUTSU (a.k.a JIU-JITSU)

Jujutsu is often known as Jiu Jitsu or Brazilian Jiu Jitsu.  

The following is taken mostly from the online encyclopedia, Wikipedia:

Jujutsu (柔術, jūjutsu): The first Chinese character “ju” literally means "soft” and the second character, “jutsu” could be translated to mean “art,” “stratagem,” or “means."  Jujutsu is a Japanese martial art consisting of grappling and striking techniques.  Jujutsu evolved among the samurai of feudal Japan as a method for dispatching an armed and armored opponent in situations where the use of weapons was impractical or forbidden.  Due to the difficulty of dispatching an armored opponent with striking techniques, the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws.  These techniques were developed around the principle of using an attacker's energy against himself, rather than directly opposing it, and came to be known as jujutsu.

There are many variations of the art, which leads to a diversity of approaches.  Jujutsu schools (ryū) may utilize all forms of grappling techniques to some degree (i.e. throwing, joint locking, holds, gouging, biting, disengagements, striking, and kicking).  In addition to jujutsu, many schools taught the use of weapons.

Today, jujutsu is still practiced both as it was hundreds of years ago, but also in modified forms for sport practice.  Derived sports forms include the Olympic sport and martial art of judo, which was developed from several traditional styles of jujutsu by Kano Jigoro in the late 19th century; and Brazilian Jiu-Jitsu, which was in turn derived from judo.

Origins

Jujutsu was first developed by the Samurai. Fighting forms have existed in Japan for centuries.  The first references to unarmed combat arts or systems is in the earliest purported historical records of Japan, the Kojiki (Record of Ancient Matters) and the Nihon Shoki (Chronicles of Japan), which relate the mythological creation of the country and the establishment of the imperial family.

The term "jūjutsu" was not coined until the 17th century, after which time it became a blanket term for a wide variety of grappling-related disciplines.  Prior to that time, these skills had names such as "short sword grappling" (小具足腰之周, kogusoku koshi no mawari?), "grappling" (組討 or 組打, kumiuchi?), "body art" (体術, taijutsu?), "softness" (柔 or 和, yawara?), "art of harmony" (和術, wajutsu?), and even the "way of softness" (柔道, jūdō?) (as early as 1724, almost two centuries before Kano Jigoro founded the modern art of Kodokan Judo).

These systems of unarmed combat began to be known as Nihon koryu jūjutsu (Japanese old-style jujutsu), among other related terms, during the Muromachi period (1333-1573), according to densho (traditional history scrolls) of the various ryuha (martial traditions) and historical records.  Most of these were battlefield systems to be used with the more common and vital weapon systems.  These fighting arts had various names, including kogusoku, yawara, kumiuchi, and hakuda, all under the general description of Sengoku jūjutsu.  They were not systems of unarmed combat, but means for an unarmed or lightly armed warrior to fight a heavily armed and armored enemy on the battlefield.  Ideally, the samurai would be armed and would not need to rely on them.

Methods of combat (as just mentioned above) included striking (kicking and punching), throwing (body throws, joint-lock throws, unbalance throws), restraining (pinning, strangulating, grappling, wrestling) and weaponry.  Defensive tactics included blocking, evading, off-balancing, blending and escaping.  Minor weapons such as the tanto (dagger), ryufundo kusari (weighted chain), kabuto wari (helmet smasher), and kakushi buki (secret or disguised weapons) were almost always included in Sengoku jujutsu.

Development

In later times, other koryu (old styles) developed into systems more familiar to the practitioners of Nihon jujutsu commonly seen today.  These are correctly classified as Edo jūjutsu (founded during the Edo period): they are generally designed to deal with opponents neither wearing armor nor in a battlefield environment.  Most systems of Edo jujutsu include extensive use of atemi waza (vital-striking technique), which would be of little use against an armored opponent on a battlefield.  They would, however, be quite valuable in confronting an enemy or opponent during peacetime dressed in normal street attire (referred to as "suhada bujutsu").  Occasionally, inconspicuous weapons such as tantō (daggers) or tessen (iron fans) were included in the curriculum of Edo jūjutsu.

Another seldom-seen historical side is a series of techniques originally included in both Sengoku and Edo jujutsu systems. Referred to as hojo waza (捕縄術 hojojutsu, nawa jutsu, hayanawa and others), it involves the use of a hojo cord, (sometimes the sageo or tasuke) to restrain or strangle an attacker.  These techniques have for the most part faded from use in modern times, but Tokyo police units still train in their use and continue to carry a hojo cord in addition to handcuffs. The very old Takenouchi-ryu is one of the better-recognized systems that continue extensive training in hojo waza.  Since the establishment of the Meiji period with the abolishment of the Samurai and the wearing of swords, the ancient tradition of Yagyu Shingan Ryu (Sendai & Edo lines) has focused much towards the jujutsu (Yawara) contained in its syllabus.

Many other legitimate Nihon jujutsu ryu exist but are not considered koryu (ancient traditions).  These are called either Gendai jūjutsu or modern jujutsu.  Modern jujutsu traditions were founded after or towards the end of the Tokugawa period (1868), when more than 2000 schools (ryu) of jūjutsu existed. Various traditional ryu and ryuha that are commonly thought of as koryu jujutsu are actually gendai jūjutsu.  Although modern in formation, very few gendai jujutsu systems have direct historical links to ancient traditions and are incorrectly referred to as traditional martial systems or ryu.  Their curriculum reflects an obvious bias towards Edo jūjutsu systems as opposed to the Sengoku jūjutsu systems.  The improbability of confronting an armor-clad attacker is the reason for this bias.

Over time, Gendai jujutsu has been embraced by law enforcement officials worldwide and continues to be the foundation for many specialized systems used by police. Perhaps the most famous of these specialized police systems is the Keisatsujutsu (police art) Taiho jutsu (arresting art) system formulated and employed by the Tokyo Police Department.

If a Japanese based martial system is formulated in modern times (post Tokugawa) but is only partially influenced by traditional Nihon jujutsu, it may be correctly referred to as goshin (self defense) jujutsu. Goshin jujutsu is usually formulated outside Japan and may include influences from other martial traditions.  Brazilian Jiu-Jitsu, which was developed from judo, but with greater emphasis on ground grappling (ne waza), is an excellent example of Goshin Jujutsu.

Jujutsu techniques have been the basis for many military unarmed combat techniques (including British/US/Russian special forces and SO1 police units) for many years.

There are many forms of sport jujutsu, the original and most popular being judo, now an Olympic sport.  One of the most common is mixed-style competitions, where competitors apply a variety of strikes, throws, and holds to score points.  There are also kata competitions, where competitors of the same style perform techniques and are judged on their performance.  There are also freestyle competitions, where competitors take turns attacking each other, and the defender is judged on performance.

Description

Japanese jujutsu systems typically place more emphasis on throwing, immobilizing and pinning, joint-locking, choking, and strangling techniques (as contrasted with other martial arts systems such as karate which is focused on atemi-waza). Atemi-waza (striking techniques) were seen as less important in most older Japanese systems, since samurai body armor protected against many striking techniques.  The Chinese quanfa/ch'uan-fa (kenpo or kung fu) systems focus on punching, striking, and kicking more than jujutsu.

The Japanese systems of hakuda, kenpo, and shubaku display some degree of Chinese influence in their emphasis on atemi-waza.  In comparison, systems that derive more directly from Japanese sources show less preference for such techniques. However, a few jujutsu schools likely have some Chinese influence in their development.  Jujutsu ryu vary widely in their techniques, and many do include significant numbers of striking techniques, if only as set-ups for their grappling techniques.

In jujutsu, practitioners train in the use of many potentially fatal moves.  However, because students mostly train in a non-competitive environment, risk is minimized.  Students are taught break falling skills to allow them to safely practice otherwise dangerous throws.

In jujutsu, there are five main sectors ("arts") of training.  The first, the Art of Blocking, is used to defend against attacks. The second, the Art of the Fulcrum Throw, is employed in modern judo.  The third, the Art of the Non-fulcrum Throw is employed through throws that involve little or no contact with the opponent.  The fourth, the Art of Escaping (Hakko-Dori), is very crucial in many styles of Jujutsu.  The fifth, the Art of Striking (Atemi-Waza), is used more by modern jujutsu-ka (practitioners of jujutsu) who do not employ body armor.

Technical characteristics

Although there is some diversity in the actual look and techniques of the various traditional jujutsu systems, there are significant technical similarities common to all schools:

    - Students learn traditional jujutsu primarily by observation and imitation of the ryu's waza.
    - The unarmed waza of most schools emphasize joint-locking techniques (kansetsu waza).
    - Sometimes, atemi (strikes) are targeted to some vulnerable area of the body; this is an aspect of kuzushi, the art of breaking balance as a set-up for a lock, take-down or throw.
    - Movements tend to capitalize on an attacker's momentum and openings in order to place a joint in a compromised position or to break their balance as preparation for a take-down or throw.
    - The defender's own body is positioned so as to take optimal advantage of the attacker's weaknesses while simultaneously presenting few openings or weaknesses of its own.
    - Weapons training was a primary goal of Samurai training. Koryu (old/classic) schools typically include the use of weapons. Weapons might include the roku shaku bo (six-foot staff), hanbo (three-foot staff), katana (long sword), wakizashi or kodachi (short sword), tanto (knife), or jitte (short one hook truncheon).

Schools and derivatives

Because jujutsu contains so many facets, it has become the foundation for a variety of styles and derivations today.  As each instructor incorporated new techniques and tactics into what was taught to him originally, he could codify and create his own ryu (school).  Some of these schools modified the source material so much that they no longer considered themselves a style of jujutsu.

Old schools

Beginnings

The art began with Mitsuyo Maeda (aka Conde Koma, or Count Combat in English), a Japanese expert judoka and member of the Kodokan.  Maeda was one of five of the Kodokan's top groundwork experts that Judo's founder Kano Jigoro sent overseas to spread his art to the world. Maeda left Japan in 1904 and visited a number of countries giving "jiu-do" demonstrations and accepting challenges from wrestlers, boxers, savate fighters and various other martial artists before eventually arriving in Brazil on November 14, 1914.

Since its inception, judo was separated from jujutsu in its goals, philosophy, and training regime. Although there was great rivalry among jujutsu teachers, this was more than just Kano's ambition to clearly individualize his art. To Kano, judo wasn't solely a martial art: it was also a sport, a method for promoting physical fitness and building character in young people, and, ultimately, a way (Do) of life.  To a very large extent, Brazilian Jiu-Jitsu has also encompassed these philosophies.

It is often claimed that BJJ is a development of traditional Japanese jujutsu, and that Maeda was a jujutsu-ka. However, Maeda never trained in jujutsu. He first trained in sumo as a teenager, and after the interest generated by stories about the success of judo at contests between judo and jujutsu that were occurring at the time, he changed from sumo to judo, becoming a student of Kano's Kodokan judo.  He was promoted to 7th dan in Kodokan judo the day before he died in 1941.

Hélio Gracie himself had already risen to the rank of 6th dan in judo by the time of his fight against Kimura in 1951.

Name

When Maeda left Japan, Judo was still often referred to as "Kano Ju-Jutsu" or, even more generically, simply as "Ju-Jutsu."

Outside Japan, however, this distinction was noted even less. The distinction between a “jutsu” and a “do” is subtle, and is still used somewhat arbitrarily to this day.

Thus, when Maeda and Satake arrived in Brazil in 1914, every newspaper announced jiu-jitsu despite both men being Kodokan Judoka.

The Japanese government itself did not officially mandate until 1925 that the correct name for the martial art taught in the Japanese public schools should be "judo" rather than "jujutsu".  In Brazil, the art is still called "Jiu-Jitsu".  When the Gracies went to the United States to spread their art, the system became known as "Brazilian Jiu-Jitsu" and "Gracie Jiu-Jitsu."

"Jiu-Jitsu" is an older romanization that was the original spelling of the art in the West, and it is still in common use, whereas the modern Hepburn romanization is "jūjutsu." Other common spellings are Jujitsu, Ju-Jitsu, and Ju jitsu.

The art is sometimes referred to as Gracie Jiu-Jitsu (GJJ), but this name is trademarked by Rorion Gracie and specifically refers to the style taught by him and his selected teachers.  Other members of the Gracie family often call their style by personalized names, such as Charles Gracie Jiu-Jitsu or Renzo Gracie Jiu-Jitsu, and similarly, the Machado brothers call their style Machado Jiu-Jitsu (MJJ). While each style and its instructors have their own unique aspects, they are all basic variations of Brazilian Jiu-Jitsu, a derivative of Kano’s judo.

Development

Maeda met an influential businessman named Gastão Gracie who helped him get established.  In 1917, his son Carlos Gracie, still a 14 year-old boy, watched a demonstration by Maeda at the Teatro da Paz and decided to learn jiu-jitsu.  Maeda accepted Carlos as a student, and Carlos went on to become a great exponent of the art and ultimately, with his younger brother Hélio Gracie became the founder of Gracie Jiu-Jitsu, modern Brazilian Jiu-Jitsu.

In 1921, Gastão Gracie and his family moved to Rio de Janeiro. Carlos, then 17 years old, passed Maeda's teachings on to his brothers Osvaldo, Gastão and Jorge.  Hélio was too young and sick at that time to learn the art, and due to medical imposition was prohibited to take part in the training sessions.  Despite that, Hélio learned jiu-jitsu by watching his brothers.  He eventually overcame his health problems and is now considered by many as the founder of Brazilian Jiu-Jitsu (though others, such as Carlson Gracie, have pointed to Carlos as the founder of the art).

Hélio competed in several submission judo competitions which mostly ended in a draw. One defeat (in Brazil in 1951) was by visiting Japanese judoka Masahiko Kimura, whose surname the Gracies gave to the arm lock used to defeat Hélio.

The Gracie family continued to develop the system throughout the 20th century, often fighting “vale tudo” (anything goes) matches (precursors to modern MMA), during which it increased its focus on ground fighting and refined its techniques.

Today, the main differences between the BJJ styles is between traditional Gracie Jiu-Jitsu's emphasis on self-defense, and Sport Brazilian Jiu-Jitsu's orientation towards point competition. There is a large commonality of techniques between the two. Also, there is a wide variety of ideals in training in different schools in terms of the utilization of technique versus how much to attempt to overpower an opponent.

Prominence

Brazilian Jiu-Jitsu came to international prominence in the martial arts community in the 1990s, when Brazilian Jiu-Jitsu expert Royce Gracie won the first, second and fourth Ultimate Fighting Championships, which at the time were single elimination martial arts tournaments.  Royce fought against often much-larger opponents who were practicing other styles, including boxing, shoot-fighting, karate, judo, tae kwon do and wrestling.  It has since become a staple art for many MMA fighters and is largely credited for bringing wide-spread attention to the importance of ground fighting.  Sport BJJ tournaments continue to grow in popularity worldwide and have given rise to no-gi submission grappling tournaments, such as the ADCC Submission Wrestling World Championship.

Comparison with Judo

Combat Strategy

Renzo Gracie wrote in his book, Mastering Jujitsu: "The classical jujutsu of old Japan appeared to have no common strategy to guide a combatant over the course of a fight.  Indeed, this was one of Kano's most fundamental and perceptive criticisms of the classical program."  Maeda not only taught the art of judo to Carlos Gracie, but also taught a particular philosophy about the nature of combat developed by Kano, and further refined by Maeda based on his world-wide travels competing against fighters skilled in a wide variety of martial arts.

The book details Maeda's theory as arguing that physical combat could be broken down into distinct phases, such as the striking phase, the grappling phase, the ground phase, etc.  Thus, it was a smart fighter's task to keep the fight located in the phase of combat that best suited his own strengths.

Renzo Gracie stated that this was a fundamental influence on the Gracie approach to combat.  These strategies were further perfected over time by the Gracies and others, and became prominent in contemporary MMA.

Free Sparring

Like judo, BJJ encourages free sparring against a live, resisting opponent.  Practitioners therefore have the opportunity to test their skills and develop them under realistic conditions, while minimizing the risk of injury. Also known as "rolling."

Divergence from Kodokan Rules

Since judo was introduced to Brazil there have been changes in the rules of sport judo—some to enhance it as a spectator sport, and some for improved safety.  Several of these rule changes have greatly de-emphasized the groundwork aspects of judo, and others have reduced the range of joint locks allowed and when they can be applied.  Many of the banned techniques are preserved in the judo kata, and are practised to varying extents in different clubs.  Brazilian Jiu-Jitsu did not follow many of these changes to judo rules, and this divergence has given it a distinct identity as a martial art, while still being recognizable as a sub-style of judo.  Other factors that have contributed towards the stylistic divergence of BJJ from sport judo include the Gracies' desire to create a national martial art, the influence of Brazilian culture, and the Gracies' emphasis on full-contact fighting and self-defense.

BJJ permits all the techniques that judo allows to take the fight to the ground. These include judo's scoring throws as well as judo's non-scoring techniques that it refers to as 'skillful takedowns' (such as the flying arm-bar).  However, BJJ differs in that it also allows a competitor to drag his opponent to the ground, and also even to drop to the ground himself provided he has first taken a grip.  Early Kodokan judo not only allowed all that BJJ now allows, it even allowed a fighter to drop straight to the ground without first taking a grip.

BJJ's different rules set and point scoring mechanisms are designed to give BJJ an arguably more practical emphasis.  This is done by rewarding positions of control from which the grappler could strike their opponent (if it weren't for the sport's restrictions against striking.)  While judo's greater emphasis on throwing is sometimes criticized as not being as useful in a self-defense situation, the effectiveness of throwing should not be underestimated.  This is especially so when performed on a hard surface and with the freedom to throw their opponent in a manner that would cause great injury (being unrestricted in the circumstances by sport judo's requirement to rotate one's opponent onto their side or back.)

Ground Fighting

BJJ is strongly differentiated by its greater emphasis on groundwork.  This is due to both its radically different point-scoring system, and the absence of most of the judo rules that cause the competitors to have to recommence in a standing position.  This has led to greater time dedicated to training on the ground, resulting in enhancement of judo's groundwork techniques by BJJ practitioners.

However, there are also many techniques that are allegedly created by BJJ, though they already existed in Kodokan judo. This misconception is often the result of incorrect assumptions by BJJ practitioners who simply assume that the techniques they learned in BJJ classes originated in BJJ, and it is also due in some instances to BJJ practitioners genuinely rediscovering techniques that they did not know already existed in judo, such as the Gogoplata which is known in judo as Katato-jime (heel choke).

Along with BJJ's great strengths on the ground comes its relative weakness with standing techniques.  There is an increasing amount of cross-training between the two sports.

The Gi

While the judogi (judo uniform) is regulated and inspected by sanctioning bodies so as to maintain a necessary amount of room between the arm and the sleeve for gripping, and also between the leg and the pants, a BJJ practitioner's gi is not generally as tightly regulated. The practitioner can therefore benefit from a closer fit, providing less material for an opponent to manipulate.

Style of Fighting

Brazilian Jiu-Jitsu emphasizes ground fighting techniques and submission holds involving joint-locks and chokeholds also found in numerous other arts with or without ground fighting emphasis.  The premise is that most of the advantage of a larger, stronger opponent comes from superior reach and more powerful strikes, both of which are somewhat negated when grappling on the ground.

BJJ permits a wide variety of techniques to take the fight to the ground after taking a grip.  Once the opponent is on the ground, a number of maneuvers (and counter-maneuvers) are available to manipulate the opponent into a suitable position for the application of a submission technique.  Achieving a dominant position on the ground is one of the hallmarks of the BJJ style, and includes effective use of the guard position to defend oneself when on the bottom, and passing the guard to dominate from top position with side control, mount, and back mount positions.  This system of maneuvering and manipulation can be likened to a form of kinetic chess when utilized by two experienced practitioners.  A submission hold is the equivalent of checkmate.

Types of Submission

The majority of submission holds can be grouped into two broad categories: joint locks and chokes.  Joint locks typically involve isolating an opponent's limb and creating a lever with the body position which will force the joint to move past its normal range of motion, generally referred to as hyperextension.  Pressure is increased in a controlled manner and released if the opponent cannot escape the hold and signals defeat by submitting. Opponents can indicate submission verbally or they can tap out (i.e. tap the opponent, the mat, or even themselves, several times.)   A choke hold, disrupting the blood supply to the brain, can cause unconsciousness if the opponent does not submit soon enough.

A less common type of submission hold is a compression lock, where the muscle of an opponent is compressed against a hard, large bone (commonly the shin or wrist), causing significant pain to the opponent.  These types of locks are not usually allowed in competition due to the high risk of tearing muscle tissue.  This type of lock often also hyper-extends the joint in the opposite direction, pulling it apart.

Joint Locks

While many joint locks are permitted, most competitions bar or restrict some or all joint locks involving the knees, ankles, and spine.  The reason for this is that the angles of manipulation required to cause pain are nearly the same as those that would cause serious injury.  Joint locks that require a twisting motion of the knee (called twisting knee locks or twisting knee bars, or techniques such as heel hooks, and toe holds) are usually banned in competitions because successfully completing the move nearly always results in permanent damage that requires surgery. Similarly, joint manipulations of the spine are typically barred due to the inherent danger of crushing or mis-aligning cervical vertebrae.  Leg locks are allowed in varying degrees depending on skill level, with straight ankle locks being the only leg locks allowed in the beginner division, or white belt level, straight kneebars being allowed in the intermediate division, or blue belt level and toe holds with the pressure applied inwards are allowed in the advanced division (purple, brown, black).

However, most joint locks involving the wrist, elbow, shoulder or ankle are permitted as there is a great deal more flexibility in those joints and those locks are safe to use under tournament conditions.  Also, some fighters practice moves whose sole purpose is to inflict pain upon their opponent, in the hope that they will tap out.  This includes driving knuckles into pressure points, holding their opponent's head in order to tire out the neck (called the "can opener" or kubi-hishigi) and putting body weight on top of the sternum, floating ribs, or similarly sensitive bones.  These moves are not true submission moves - they are generally only used as distractions mostly in lower levels of competition.  They are avoided or aggressively countered in middle to upper levels of competition.

Chokes and Strangles

Chokes and strangles are a common form of submission. Chokes involve constriction of the windpipe (causing asphyxia.) Strangles involve constriction of the carotid artery (causing ischemia.)

Air chokes are less efficient than strangles and may result in damage to the opponent's trachea, sometimes even resulting in death.  By contrast, blood chokes (strangulations) cut the flow of blood to the opponent's brain, causing a rapid loss of consciousness without damaging any internal structures.  Being "choked-out" in this way is relatively safe as long as the choke is released soon enough after unconsciousness, letting blood back into the brain before oxygen deprivation damage begins.   However, it should not be practiced unsupervised.

The prevalence of the more dangerous "air" chokes has led to the banning of choke holds from some United States police departments. Because of the negative legal connotations of the words "choke" and "strangulation", it is advisable to use the term "lateral vascular restraint" when describing a blood choke used in a self-defense situation.

Training Methods

Sport Brazilian Jiu-Jitsu's focus on submissions without the use of strikes while training allows practitioners to practice at full speed and with full power, resembling the effort used in a real competition. Training methods include technique drills in which techniques are practiced against a non-resisting partner; isolation sparring where only a certain technique or sets of techniques are used against full resistance; and full sparring in which each opponent tries to submit their opponent using any legal technique. Physical conditioning is also an important part of training at many clubs.
