There are many variations of the art, which leads to a diversity of approaches. Jujutsu schools (ryu) 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.
Judo was developed by Jigoro Kano in the late 19th century from several traditional styles of jujutsu, and Brazilian jiu-jitsu was derived from earlier (pre–World War II) versions of Kodokan judo.
The major traditonal style that most influences Ryuu Shin today is Daito Ryu Aiki Jujutsu, whose originator was Sokaku Takeda.
