„Jū“ can be translated to mean „gentle, soft, supple, flexible, pliable, or yielding.“ „Jutsu“ can be translated to mean „art“ or „technique“ and represents manipulating the opponent’s force against themselves rather than confronting it with one’s own force.[1] Jujutsu developed to combat the samurai of feudal Japan as a method for defeating an armed and armored opponent in which one uses no weapon, or only a short weapon.[3] Because striking against an armored opponent proved ineffective, practitioners learned that 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 him, rather than directly opposing it.[4]
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, trapping, joint locks, holds, gouging, biting, disengagements, striking, and kicking). In addition to jujutsu, many schools teach the use of weapons. Today, jujutsu is practiced in both traditional and modern sports forms. Derived sport forms include the Olympic sport and martial art of judo, which was developed by Kanō Jigorō in the late 19th century from several traditional styles of jujutsu, and Brazilian jiu-jitsu, which was derived from earlier (pre–World War II) versions of Kodokan judo.
Jujutsu, the current standard spelling, is derived using the Hepburn romanization system. Before the first half of the 20th century, however, Jiu-Jitsu and Ju-Jitsu were preferred, even though the romanization of the second kanji as Jitsu is unfaithful to the standard Japanese pronunciation. Since Japanese martial arts first became widely known of in the West in that time period, these earlier spellings are still common in many places. Ju-Jitsu is still a common spelling in France, Canada, and the United Kingdom while Jiu-Jitsu is most widely used in Germany and Brazil.
Some define jujutsu and similar arts rather narrowly as „unarmed“ close combat systems used to defeat or control an enemy who is similarly unarmed. Basic methods of attack include hitting or striking, thrusting or punching, kicking, throwing, pinning or immobilizing, strangling, and joint locking. Great pains were also taken by the bushi (classic warriors) to develop effective methods of defense, including parrying or blocking strikes, thrusts and kicks, receiving throws or joint locking techniques (i.e., falling safely and knowing how to „blend“ to neutralize a technique’s effect), releasing oneself from an enemy’s grasp, and changing or shifting one’s position to evade or neutralize an attack. As jujutsu is a collective term, some schools or ryu adopted the principle of ju more than others.
From a broader point of view, based on the curricula of many of the classical Japanese arts themselves, however, these arts may perhaps be more accurately defined as unarmed methods of dealing with an enemy who was armed, together with methods of using minor weapons such as the jutte (truncheon; also called jitter), tantō (knife), or Kaku shi buki (hidden weapons), such as the ryofundo kusari (weighted chain) or the bankokuchoki (a type of knuckle-duster), to defeat both armed or unarmed opponents.
Furthermore, the term jujutsu was also sometimes used to refer to tactics for infighting used with the warrior’s major weapons: katana or tachi (sword), yari (spear), naginata (glaive), and jō (short staff), bō (quarterstaff). These close combat methods were an important part of the different martial systems that were developed for use on the battlefield. They can be generally characterized as either Sengoku period (1467–1603) katchu bu Jutsu or yoroi kumiuchi (fighting with weapons or grappling while clad in armor), or Edo period (1603–1867) suhada bu Jutsu (fighting while dressed in the normal street clothing of the period, kimono and hakama).
The Chinese character 柔 (Mandarin: róu; Japanese: jū; Korean: yū) is the same as the first one in 柔道/judo (Mandarin: róudào; Japanese: jūdō; Korean: Yudo). The Chinese character 術 (Mandarin: shù; Japanese: jutsu; Korean: sul) is the same as the second one in 武術 (Mandarin: wǔshù; Japanese: bujutsu; Korean: musul).
