When you think of Judo you first imagine spectacular throwing techniques. But it is a very safe sport, as it has strict rules that govern competition and ensure safety.
It is learned on special mats for comfort and safety. The official contest area is a 14.55m x 14.55m square, with a 9.1m x 9.1m square area in its center. It is called “tatami”. You can see it in the picture at the right.
You can not wear anything that can cause damage to your oponent or to yourself, such as bracelets, rings or earings.
There are separate weight divisions for men and women, so you fight against opponents of your sex and approximate weight.

Judo created the system of ranks, now used in most other martial arts. Ranks recognize a person's degree of knowledge, ability, and leadership.
Judo ranks are identified by coloured belts, and ten degrees of advanced grades for black belts. Belt colors are:
