Judo is one of the most well known of the traditional Japanese sports. Judo means that even a small wrestler can use the strength and weight of his opponent to overwhelm him. The main techniques are throwing and combination techniques. The purpose of judo is not only to defeat the opponent, but also to train the body and mind. White is the lowest, followed by brown, black is worn from 1st to 5th dan, red and white from 6th to 8th dan, and red from 9th to 10th dan. Judo is the official Olympic discipline for men, and competitors are categorized according to their weight.

Jiu-Jitsu has its roots in sumo wrestling, and you can find descriptions of it in old books that record the history of Japan in the mythical age of the gods

In the Middle Ages, Japan was ruled by a class of professional soldiers called samurai. This provides fertile ground for a variety of martial arts to develop. In addition to fighting with the sword and bow and arrow, the jujutsu developed by the warrior was for fighting the enemy at close range on the battlefield. Several different styles of jujitsu evolved and hand-to-hand combat spread as an important form of military training.

With the end of the Samurai era, Western culture began to permeate Japanese society and Jiu-Jitsu declined, but one young man’s enthusiasm saved it from extinction. That is the founder of today’s judo. He excelled academically but felt inferior due to his petite physique. So he strived to become stronger, and at only 21 years of age, he created a new school, taking the good parts of each jiu-jitsu and creating one. This was the birth of modern judo. Initially, there were only nine disciples, and the dojo (practice hall) was only 12 jō (about 24 square yards).

He then went to Europe to introduce judo to other countries. There is a famous episode aboard the ship during the voyage. When a foreigner made fun of him, he threw him down, but he put his hands under his head so that the person would not get hurt. This shows how judo combines a practical way of fighting with compassion for the enemy.

Many countries and regions are now members of the International Judo Federation. This sport is especially popular in Europe. In fact, more people practice judo in France than in Japan. Japan continues to promote judo overseas by sending instructors to Africa, Oceania and other areas where judo is not well known, and by donating used judo jackets.
