Types of Judo Belts

Colored judo belts were introduced by the Japanese, and were related to the age of the student. The following article will cover all the required information related to these belts, that identify the competence level of an individual.

Achievements in judo are recognized by the series of ranks one earns. Student ranks are called kyu, and are differentiated with the help of colored belts called obi. After one passes through the 'kyu' level or below black belt level 'grades', they move on to the black belt level 'degrees'. These degrees are known as dan. The system of varyingly-colored belts signifying the wearer's grade was invented by an early judo exponent Mikonosuke Kawaishi. Kawaishi was proficient in jujitsu and judo, and taught judo in England and France. He felt that, since judo was based upon the Oriental Japanese culture, it needed some tweaks to attract more Westerners. The grade system caught on in France, and helped spread judo in the West. The Westernized style promoted by Kawaishi, came to be known after him as the Kawaishi Ryu Jujitsu.
Judogi
A judo uniform can be white or blue in color, and is made from cotton fabric. It is called the Judogi, and includes white cotton drawstring pants and a white quilted cotton jacket that is fastened by a colored judo belt. The colors are indicative of the kyu or dan rank.
