Mostly a name for modern practical self-defense systems, which are founded after WWII in western countries as a combination of Judo, Karate and Aikido, specialized to use it against modern day attacks. Synonymous words like Jujitsu, Ju-Jitsu or Ju-Jutsu are widely used.
Also name of a combination of western boxing and wrestling with self-defense "tricks", brought from Japan to Europe and the US around 1900 to 1920. In later years often practiced as a companion to judo or as "judo self-defense" until the modern systems were founded. This Jiu-Jitsu often was presented in film, e.g. in the Mr. Moto movies (starring Peter Lorre).
Self-defense arts called Jiu-Jitsu should not be mistaken with ancient Japanese Jujutsu styles, which are traditional, classical bujutsu (martial skills) of the Japanese warriors (samurai) and are in fact koryu (ancient budo). They have not much in common with the Jiu-Jitsu we know.

(Japanese) Jiu Jitsu is most defenetly the best martial art there is. The objecitive is to weaken your opponent by kicking and punching. After that you throw him/her on the ground and choke or hold your opponent to make him/her give up.

Unlike karate you dont have to bow to every fucking thing in the room.

Brazilian Jiu-Jitsu

Brazilian Jiu-Jitsu (BJJ), also known as Gracie Jiu-Jitsu (GJJ), is a martial art that was developed in Brazil by the Gracie family during the mid-20th century. Originally based on the Japanese Martial art of Judo as it existed before World War II, it has since developed into a relatively independent system with a large emphasis on ground fighting and grappling.


History
A Japanese judoka, prizefighter, and former member of the Kodokan named Mitsuo Maeda emigrated to Brazil in the 1910s and was helped greatly by a Brazillian politician named Gastão Gracie. In return for his aid, Maeda taught Judo to Gastão's son Carlos, who then taught the art to his brothers, including Hélio Gracie. Through their own study and development, Carlos and Hélio are regarded as the originators of Brazilian Jiu-Jitsu as a style distinct from Kodokan Judo.

Brazilian Jiu-Jitsu became internationally prominent in the martial arts community in the 1990s, when Brazilian Jiu-Jitsu expert Royce Gracie won several single elimination martial arts tournaments called Ultimate Fighting Championships against sometimes much larger opponents who were practicing other styles.

Brazilian Jiu-Jitsu inherited its emphasis on using off-balancing, leverage, and the opponent's own power, as well as a majority of its technique from Kodokan Judo. However, there has been considerable divergence since that time as Brazilian Jiu-Jitsu evolved. Some argue that the differences are more in culture and moral goals than in the physical principles and techniques of the two arts.

The main difference is that Judo, especially in its Olympic sport form emphasizes throws, while Jiu-Jitsu emphasizes submission of the opponent using joint locks or chokes. Judo has a much higher amount of referee intervention; in Judo matches, the competitors are often returned to the standing position, while in Jiu-Jitsu matches, the participants are generally allowed to remain on the ground while working towards a submission.

Contributing factors to the divergence include the Gracies' desire to create a national martial art, the influence of Brazilian culture, the non-participation of the Gracie schools in sport judo, the post World War II closing of the Kodokan by the American Ocupation Authority (which were only allowed to reopen on the condition that emphasis be shifted towards sport), as well as the Gracies' own additions to the body of technique and opinions regarding self-defense, martial arts and training methods; and, more recently, the influence of mixed-martial-art competitions such as the Ultimate Fighting Championship.

Brazilian jiu-jitsu (BJJ) is a martial art focusing largely on grappling and ground fighting. It utilizes natural body leverage and proper technique to obtain dominant control on the ground and, as a result, provides greater position for striking or submission holds. BJJ has been proven, when used properly, to be an effective method for dealing with bigger and stronger opponents and has become increasingly popular due in part to its great success in the Ultimate Fighting Championship. It can be trained for self defense, sport grappling (gi and no-gi) and mixed martial arts competition and has found its way into the training regiment of nearly every successful martial artist worldwide.
Translated as “the gentle art,” Brazilian jiu-jitsu focuses on using strength and technique in the most efficient way possible to control and overcome opponents of greater size, strength and aggression. With its roots in the Japanese jiu-jitsu of the late 19th and early 20th centuries, the art found its way to Brazil in 1910, when Mitsuyo Maeda, a Japanese jiu-jitsu and judo expert, emigrated to the country. There he became friends with Gastao Gracie, an influential businessman who helped Maeda get established. In return, Maeda taught jiu-jitsu to Gracie’s sons, who became very proficient in the art, eventually passing on Maeda’s teaching in their own schools. The many additions, modifications, and refinements to the art made by the Gracie family were tested against other styles with great success, propelling Gracie jiu-jitsu into the martial arts world and creating a tradition that lives on today. Matt and Nick Serra are the first American black belts under Renzo Gracie, a senior member of the Gracie family world-renowned for his accomplishments in Brazilian jiu-jitsu and MMA. Matt and Nick are proud to carry on the Gracie tradition, sharing their expertise and leadership, as well as their own experiences in jiu-jitsu and mixed martial arts, with their students today.
