In 1882, the educator Jigoro Kano (who later became head of the Tokyo Higher Normal School) personally financed and opened the Kodokan for the study and instruction of judo. This formed the starting-point of the development of modern judo from jujutsu, one of the ancient martial arts.

The aim in judo is not win contests; rather it to train the mind and body. At the beginning of the twentieth century judo became part of the educational curriculum of boys from middle school onwards, and since then it has become very widespread.

In a judo match two participants, each wearing jacket, trousers and belt, contest in an area nine meters square (on fifty tatami mats), and each tries to win by using throwing techniques or grappling techniques.

The ju of judo means “soft” or “gentle”, and the sport was named after the principle shown in the saying ju yoku gou o seisu ―”softness overcomes hardness”. It is unusual for a sport to thus be named according to the principle it works on.

The ability of judo practitioners is indicated by dan and kyu grades. Tenth dan is the highest of the dan grades, and shodan (first dan) the lowest. Kyu grades rank below dan, and first kyu is the highest and fifth kyu the lowest of the kyu grades. These various grades are indicated by the color of the belts worn: red for ninth and tenth dan, red and white for sixth to eighth dan, and black for first to fifth dan. First to third kyu wear brown belts, fourth and fifth kyu white belts, and beginners blue belts.
