Derivatives and influences

Some examples of martial arts that have developed from or have been influenced by jujutsu are: Aikido, Bartitsu, Hapkido, Judo (and thence Brazilian Jiu-Jitsu and Sambo), Kajukenbo, Kudo, Kapap, and Kenpo – as well as some styles of Japanese Karate. The Wado-ryu school of Karate, for example, is considered as a branch of Shindō Yōshin-ryū Jujutsu which has received strong influences from Okinawan Karate.

Some schools went on to diverge into present day Karate and Aiki styles. The last Japanese divergence occurred in 1905 when a number of jujutsu schools joined the Kodokan. The syllabi of those schools was unified under Kano Jigoro to form Judo.
Bartitsu

Jujutsu was first introduced to Europe in 1898 by Edward William Barton-Wright, who had studied Tenjin Shinyō-ryū and Shinden Fudo Ryu in Yokohama and Kobe, respectively. He had 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 French stick fighting, into an eclectic self-defence system called Bartitsu.
Judo

Modern judo is the classic example of a 'sport' that derived from jujutsu and became distinct - (although many who study Judo still believe as Kano did, that Judo isn't a sport but a self defense system creating a pathway towards peace and universal harmony through the art and physical exercise), Another layer removed, some popular arts had instructors who studied one of these jujutsu derivatives and later made their own derivative succeed in 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. Because in jujutsu every conceivable technique (including biting, hair-pulling, eye-gouging, groin hits, etcetera) is allowed (unlike, for instance, judo, which does not place emphasis on punching or kicking tactics, or karate, which does not heavily emphasize grappling and throwing), practitioners have an unlimited choice of techniques.

Not all jujutsu was used in sporting contests, but the practical use in the samurai world ended circa 1890. Techniques like hair-pulling and eye poking were and are not considered conventionally acceptable to use in sport, thus they are not included in judo competitions or randori. Judo did, however, preserve the 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 fully legitimate way to win. Kano viewed the safe 'contest' aspect of judo as an important part of learning how to actually control an opponent's body in a real fight. Kano always considered judo to be a form of, and a development of, jujutsu.

A Judo technique starts with gripping your opponent followed by off-balancing the opponent and using his momentum against him, and then applying the technique. Kuzushi(the art of breaking balance) is also used in Jujitsu, where the opponent's attack is deflected using his/her momentum against them in order to arrest their movements then throw them or pin them with a technique - thus controlling the opponent. In both systems, kuzushi is essential in order to use as little energy as possible. Jujutsu differs from judo in a number of ways. In some circumstances, jutsuka generate kuzushi by striking one's opponent along his weak line. Other methods of generating kuzushi include grabbing, twisting, or poking areas of the body known as atemi points or pressure points (see kyusho-jitsu) (areas of the body where nerves are close to the skin).
 

Brazilian Jiu-Jitsu

Brazilian Jiu-Jitsu (BJJ) was developed after Mitsuyo Maeda brought judo to Brazil in 1914. At the time, judo was still often commonly referred to as "Jiu-Jitsu", which explains why this derivative of judo is called Brazilian Jiu-Jitsu rather than Brazilian Judo. BJJ dominated the first large modern mixed martial arts competitions, causing the emerging field to adopt many of its practices.

Modern schools

A Japanese-based martial system formulated in modern times (post Tokugawa) that is only partially influenced by traditional Nihon jujutsu, is 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, although derived originally from Kodokan Judo, has evolved independently for many years, and could be considered an example of Goshin Jutsu.

After the transplantation of traditional Japanese jujutsu to the West, many of these more traditional styles underwent a process of adaptation at the hands of Western practitioners, molding the art of jujutsu to suit western culture in its myriad varieties. There are today many distinctly westernized styles of jujutsu, that stick to their Japanese roots to varying degrees.

There are a number of relatively new martial systems identifying themselves as jujutsu. Since they are created in modern (gendai) times, they are often referred to as gendai jujutsu.

Some of the largest post-reformation (founded post 1905) jujutsu schools include (but are certainly not limited to these in that there are hundreds (possibly thousands), of new branches of “jujutsu”):

Sport jujutsu

There are many types of Sport Jujutsu. One version of Sport jujutsu is known as "JJIF Rules Sport Ju-Jitsu", is organized by Ju-Jitsu International Federation (JJIF), and has been recognized as one of the sport of the World Games.

Sport Jujutsu comes in two main variants: Duo (self-defense demonstration) where both the tori (attacker) and the uke (defender) come from the same team and demonstrate self defense techniques, and Fighting System (freefighting) where competitors combine striking, grappling and submissions under rules which emphasise safety. Many of the potentially dangerous techniques such as scissor takedowns, necklocks and digital choking and locking are prohibited in Sport Jujutsu. There are a number of other styles of sport jujutsu with varying rules.
