Judo is a martial art that makes use of throws, strangles and joint locks.
There is no kicking or punching in Judo. Judo was originally developed from
Jujutsu and was accepted as an Olympic sport in 1966.

The lethal techniques and
strikes of Jujutsu have been removed from the syllabus, and Judo's founder Kano
designed a syllabus that was meant to aid in the physical fitness of the
Japanese people as well as their character development. As such, Judo was
always designed more to be a sport than a self-defence system.
The
black belt system, that pertains until today in many martial arts
(also see:
Goju Ryu Karate Belt
System) is said to have first developed in Judo. Whereas in the West, great
value is placed on the coveted achievement of a black belt, Japanese instructors
see the black belt as a stage of the student when the real study of the martial art
begins.
