Judo was first established by master Kano Jigoro with the founding of Kodokan School in 1882.
It is a type of martial arts which derived from jujutsu, another kind of martial arts which its basic idea is to offend and defend from enemies with and without weapons.
Although Kano was very smart and marked high grades in his studies, his body was very weak and was rather sickly.
For his health condition he was a good target of bullying since he was a child, and to overcome his weakness he started to study jujutsu.
He gathered only the strong points of each jujutsu school, weeded out the dangerous parts, devised ways to improve the art and finally founded Kodokan, a completely new school of judo.
For Kano, judo and the purpose of training was nothing more than education, and he divided judo into three ways.
- Judo as a way of fighting: judo is fought on the rigid rules of dynamics, is scientific, and strong-arm methods going against dynamics rule is remonstrated.
- Judo as a way of physical training: aggressive and rough tricks are to be avoided, and physical training is to be achieved by repetitive practices of offense and defense.
- Judo as a way of moral training: formation of proper ethics and personality is achieved by respecting ruled and manners, and contributes to the society.
Today, especially the 2nd and 3rd ways have attracted much sympathy from a wide range of people and judo has become a popular sport all over the world.
It is now a formal event of the summer Olympic Games, and in many Japanese schools taken into P.E. classes for boys.
