Usage
What is judo? Judo is a martial art and unarmed self-defense system focused on throwing or pinning with a minimum amount of physical effort. It is based on jujitsu. Judo is also a sport and an event in the Summer Olympic Games. In the sport of judo, the object is to score points by throwing or pinning one’s opponent. Names of points awarded for different kinds of throws or holds include yuko and waza-ari. A point known as an ippon is awarded to a competitor who displays perfect technique and results in an automatic victory in the match. A minor penalty is called a shido. A major penalty is known as a hansoku-make and results in disqualification. Many of the throwing techniques used in judo have been adopted in other sparring sports, including in mixed martial arts. A person who practices or competes in judo can be called a judoka. Example: I practice judo, but not competitively—just for self defense and exercise.

Explanation
Judo is a Japanese martial art. Practicing judo is sometimes dance-like and meditative, but it can also be competitive, with opponents attempting to throw each other to the ground. Like most other modern martial arts, judo is an unarmed fighting technique that requires both a well-trained body and mind. It was created in the 1880s by a Japanese athlete and teacher who was strongly influenced by jujitsu. Today, millions of people practice judo, some of them competing annually in tournaments. You can tell how experienced someone is by the color of their belt, ranging from white (beginner) to black.
