Judo: origin, history and rules of this martial art

What is Judo?

Judo has been a Japanese martial art and an Olympic combat sport since 1964.

This self-defense sport aims to improve motor coordination, concentration, self-confidence, in addition to strengthening the physique, spirit and mind.

Currently, judo is a sport widely practiced in the world by adults and children, men, women and the elderly.

Origin and History of Judo

The practice of judo was created in 1882 in Japan by the master Jigoro Kano. In the same year, he created the Kodokan Institute which taught the techniques and philosophy associated with the sport.

In the words of its creator:

Art in which physical and spiritual strength is used to the full.

To create this martial art, he brought together some elements of other ancient martial arts, and shortly after being created, it was made official in Japan.

To a large extent, judo is derived from Ju-jutsu who uses his body to attack his opponent and defend himself.

Foundation of the first Judo school

The first judo school was created in Japan by its founder, Jigoro Kano: the Kodokan.

In addition to developing combat techniques for the sport, the founder combined this martial art with the philosophy ippon-shobu (fighting for the perfect point).

Judo in Brazil

In Brazil, this martial art arrived at the beginning of the 20th century with Japanese immigration to the country. From 1920 onwards, some judo academies were created in the city of São Paulo.

The practice also began to spread to other states in Brazil, however, it was only institutionalized with the creation of the Brazilian Judo Confederation (CBJ) in 1969.

The Creation of the Brazilian Judo Confederation (CBJ)

The Brazilian Judo Confederation (CBJ) was founded on March 18, 1969 in Rio de Janeiro. Without a doubt, she allowed the development of judo in Brazil, administering, coordinating and organizing the practice.
