As jujutsu has 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 them originally, they codified and developed their own
ryu (school) or Federation to help other instructors, schools, and clubs. Some of these schools modified the source material enough that they no longer consider themselves a style of jujutsu. Arguments and discussions amongst the martial arts fraternity have evoked to the topic of whether specific methods are in fact not jujitsu at all. Tracing the history of a specific school can be cumbersome and impossible in some circumstances. Around the year 1600, there were over 2000 jujutsu
ko-ryū styles, most with at least some common descent, characteristics, and shared techniques. Specific technical characteristics, a list of techniques, and the way techniques were performed varied from school to school. Many of the generalizations noted above do not hold true for some schools of jujutsu. Schools of jujutsu with long lineages include: •

Ryōi Shintō-ryū Aikido Aikido is a modern martial art developed primarily during the late 1920s through the 1930s by
Morihei Ueshiba from the system of
Daitō-ryū Aiki-jūjutsu. Ueshiba was an accomplished student of
Takeda Sokaku with aikido being a systemic refinement of defensive techniques from Aiki-Jujutsu in ways that are intended to prevent harm to either the attacker or the defender. Aikido changed much during Ueshiba's lifetime, so earlier styles (such as
Yoshinkan) are more like the original Aiki-Jujutsu than ones (such as
Ki-Aikido) that more resemble the techniques and philosophy that Ueshiba stressed towards the end of his life.
Wado Ryu Karate Wadō-ryū (和道流) is one of the four major karate styles and was founded by Hironori Otsuka (1892–1982). Wadō-ryū is a hybrid of Japanese Martial Arts such as Shindō Yōshin-ryū Ju-jitsu, Shotokan Karate, and Shito Ryu Karate. The style itself emphasizes not only striking but also tai sabaki, joint locks, and throws. It has its origins within Tomari-te. From one point of view, Wadō-ryū might be considered a style of jū-jutsu rather than karate. Hironori Ōtsuka embraced ju-jitsu and was its chief instructor for a time. When Ōtsuka first registered his school with the Dai Nippon Butoku Kai in 1938, the style was called "Shinshu Wadō-ryū Karate-Jūjutsu", a name that reflects its hybrid character. Ōtsuka was a licensed Shindō Yōshin-ryū practitioner and a student of Yōshin-ryū when he first met the Okinawan karate master Gichin Funakoshi. After having learned from Funakoshi, and after their split, with Okinawan masters such as Kenwa Mabuni and Motobu Chōki, Ōtsuka merged Shindō Yōshin-ryū with Okinawan karate. The result of Ōtsuka's efforts is Wadō-ryū Karate.
Bartitsu Jujutsu was first introduced to Europe in 1898 by
Edward William Barton-Wright, who had studied
Tenjin Shinyō-ryū and
Shinden Fudo-ryū in
Yokohama and
Kobe. He also trained briefly at the
Kodokan in
Tokyo. Upon returning to England he folded the basics of all of these styles, as well as
boxing,
savate, and forms of
stick fighting, into an eclectic self-defense system called
Bartitsu.
Judo , founder of judo Modern judo is a classic example of a sport that is derived from jujutsu. Many who study judo believe as Kanō did, that judo is not a sport but a self-defense system creating a pathway towards peace and universal harmony. Another layer removed, some popular arts had instructors who studied one of these jujutsu derivatives and later made their own derivative succeed in the competition. This created an extensive family of martial arts and sports that can trace their lineage to jujutsu in some part. The way an opponent is dealt with also depends on the teacher's philosophy with regard to combat. This translates also in different styles or schools of jujutsu. Not all jujutsu was used in sporting contests, but the practical use in the samurai world ended circa 1890. Techniques like hair-pulling, eye-poking, and groin attacks were and are not considered acceptable in sport, thus, they are excluded from judo competitions or
randori. However, judo did preserve some more lethal, dangerous techniques in its
kata. The kata were intended to be practiced by students of all grades but now are mostly practiced formally as complete set routines for performance, kata competition and grading, rather than as individual self-defense techniques in class. However, judo retained the full set of choking and strangling techniques for its sporting form and all manner of joint locks. Even judo's pinning techniques have pain-generating, spine-and-rib-squeezing, and smothering aspects. A submission induced by a legal pin is considered a legitimate win. Kanō viewed the safe "contest" aspect of judo as an important part of learning how to control an opponent's body in a real fight. Kanō always considered judo a form of, and development of, jujutsu. A judo technique starts with gripping the opponent, followed by off-balancing them and using their momentum against them and then applying the technique. Kuzushi (the art of breaking balance) is also used in jujutsu, whereby an opponent's attack is deflected using their momentum against them in order to arrest their movements then throw them or pin them with a technique — thus controlling the opponent. It is known in both systems that kuzushi is essential in order to use as little energy as possible. Jujutsu differs from judo in a number of ways. In some circumstances, judoka generates kuzushi by striking one's opponent along his weak line. Other methods of generating kuzushi include grabbing, twisting, poking or striking areas of the body known as
atemi points or pressure points (areas of the body where nerves are close to the skin – see
kyusho-jitsu) to unbalance opponent and set up throws.
Brazilian jiu-jitsu Brazilian jiu-jitsu (BJJ) was developed after
Mitsuyo Maeda brought judo to Brazil in 1914. Maeda agreed to teach the art to
Luiz França, Jacintho Ferro and
Carlos Gracie, son of his friend, businessman, and politician
Gastão Gracie. Luiz França went on to teach it to
Oswaldo Fadda. After Carlos learned the art from Ferro and Maeda, he passed his knowledge to his brothers Oswaldo, Gastão Jr., and George. Meanwhile,
Hélio Gracie would peek in and practice the techniques, although he was told he was too young to practice. At the time, Judo was still commonly called Kanō jiu-jitsu (from its founder Kanō Jigorō), which is why this style variation is called
Brazilian jiu-jitsu. Its emphasis shifted to
ground fighting because the
Gracie family thought that it was easier to learn than throws and standup fighting, and was also more adequate to the physical limitations of a smaller or scrawny person. Carlos and Hélio developed the style by promoting
challenge fights against practitioners of other martial arts, competitions, and experimenting throughout decades of training. The success of the BJJ specialist
Royce Gracie in the first worldwide modern
MMA competition, the
UFC, brought prominence to BJJ and is largely credited for bringing attention to the importance of ground fighting in mixed martial arts, causing the emerging field to adopt many of its practices. BJJ is primarily a ground-based fighting style that applies close range grappling techniques and uses joint locks and chokeholds to submit the adversary (
submission grappling). But less-practiced stand-up techniques in Gracie jiujitsu survive in some BJJ clubs from its judo and jujutsu heritage (judo throws, knife defense, gun defense, blocking, striking, etc.)
Sambo (right) shows a set-up for a standard Sambo arm-knot, which, if proceeded further, would turn into a standing
Nelson hold without
taking down the opponent. Sambo (an acronym from
samozashchita bez oruzhia, Russian for "
self-defense without a weapon") was an early Soviet martial art, a direct descendant of judo, developed in the 1920s by
Viktor Spiridonov, a
Russo-Japanese War veteran and
Dynamo Sports Society jujutsu instructor. As it was developed largely for police purposes, a special emphasis in Sambo was placed on the standing
armlocks and grappling counters in order to free oneself from holding, apprehending, and escorting a suspect without taking him down; Sambo utilized
throws mainly as a defensive counter in case of a surprise attack from behind. Instead of
takedowns, it used shakedowns to unbalance the opponent without actually dropping him down, while oneself still maintaining a
steady balance. It was, in essence, a standing arm-wrestling, armlock mastery-type of martial art, which utilized a variety of different types of armlocks, knots and compression holds (and counters to protect oneself from them) applied to the opponent's fingers, thumbs, wrist, forearm, elbow, biceps, shoulder, and neck, coupled with
finger pressure on various
trigger points of the human body, particularly sensitive to painful pressure, as well as manipulating the opponent's
sleeve and
collar to immobilize his upper body, extremities, and subdue him. Sambo combined jujutsu with wrestling, boxing, and savage techniques for extreme street situations. Later, in the late 1930s it was methodized by Spiridonov's trainee Vladislav Volkov to be taught at military and police academies, and eventually combined with the judo-based wrestling technique developed by
Vasili Oshchepkov, who was the third foreigner to learn judo in Japan and earned a second-degree black belt awarded by Kanō Jigorō himself, encompassing traditional Central Asian styles of
folk wrestling researched by Oshchepkov's disciple
Anatoly Kharlampiyev to create
sambo. As Spiridonov and Oshchepkov disliked each other very much, and both opposed vehemently to unify their effort, it took their disciples to settle the differences and produce a combined system. Modern sports sambo is similar to sport judo or sport Brazilian jiu-jitsu with differences including use of a
sambovka jacket and shorts rather than a full
keikogi, and a special emphasis on
leglocks and holds, but with much less emphasis on
guard and chokes (banned in competition). == Modern schools ==
