1 what is Judo
Judo is a Japanese word meaning "gentle way," and is a type of martial art that comes from the ancient Japanese martial art of jujitsu, meaning "yielding way." In 1882, Dr. Jigoro Dano, president of Tokyo's University of Education, incorporated what he thought to be the best jujitsu techniques into what is now the sport of judo. Judo emphasizes using balance, leverage, and movement in all of its skills, especially throws.
Practitioners of judo wear a cotton uniform called a judogi, meaning "judo uniform," and sometimes referred to simply as a gi. These uniforms are usually white but can also be blue. They consist of loose drawstring pants and a quilted jacket which is fastened by an obi, or belt. The uniforms were originally created for judo but are now used for many different types of martial arts.
The most noticeable thing to someone watching judo would likely be the variety of powerful throwing techniques. Grappling techniques are also important to learn, and include various control holds, arm and joint locks, pins, and choking techniques. Safety is emphasized in practice, and judo places importance both on fighting done standing and on the ground.
Judo prizes the idea of flexibility in the techniques, tailoring the technique to what is required in a particular moment. Strength is not as important as technique and skill, as well as timing. This enables judo techniques to be performed effectively by a smaller person on a much stronger person.
Judo is popular today with people of all ages, throughout the world. It is an excellent way to stay in shape, as well as increase self-confidence and learn self defense. Body control is developed, as well as quick reflexes, balance, and effective self-defense should the need arise.
Judo is also a competitive sport, introduced as such at the 1964 Olympics. This Olympic sport was only open to men until 1988, when it was a women's demonstration sport; in 1992, judo became an official Olympic medal event for women. There are also collegiate judo competitions in the United States.
The system of ranks found in many martial arts, usually identified by belts of different colors, was first used in judo. The ranks recognize hard work, as well as increased knowledge and ability of the martial art. There are separate junior ranks for children under 17 than there are for adults. Black belts are the highest ranks in judo, with ten different degrees of black belt.
Jigoro Kano is the first person who did the Judo as the sport, and he has been the most famous person in the Judo world. Therefore, now Kano Jigoro cup has begun since the late of 19th century.
2 History of Judo
Back in 1860 Jigoro Kano - judo's founder - was born in Japan. During that time peasants used forms of ju-jitsu to defend themselves, and when he was 23 years old, Kano began instructing his own form of ju-jitsu. He called it Kano Judo.
The judo, Kano showed his pupils was not just a sport but a way of life. He based his teachings around the principles of gentleness. In his own words, "Victory over the opponent is achieved by giving way to the strength of the opponent, adapting to it and taking advantage of it, turning it, in the end to your own advantage."
Kano became the first Asian IOC member in 1912 and began to travel Internationally promoting judo as he toured throughout America and Europe. In 1938 Kano died of pneumonia but not before seeing Tokyo selected as an Olympic site for the 12th Olympic Games.
However, because of the war, those Games were cancelled - and in the end it wasn't until the 1964 Games in Tokyo that judo became an Olympic sport. Some three decades later women's judo was included as an official sport at the 1992 Barcelona Olympic Games.
3 Judo rank system.
Achievement in Judo is recognized by a series of ranks. The student ranks are called kyu and are usually differentiated by colored belts (obi). Different colors may be used around the world and in some countries there are more than 6 kyu ranks. The ten black belt, or expert, ranks are called dan. The traditional Judo ranks are:
English Japanese
6th grade rokyu
5th grade gokyu
4th grade yonkyu
3rd grade sankyu
2nd grade nikyu
1st grade ikkyu
1st degree shodan
2nd degree nidan
3rd degree sandan
4th degree yodan
5th degree godan
6th degree rokudan
7th degree shichidan
8th degree hachidan
9th degree kudan
10th degree judan
In the days before Kano created Judo, there was no kyu/dan ranking system in the martial arts. A more traditional method of recognizing achievement was the presentation of certificates or scrolls, often with the secrets of the school inscribed. Kano started the modern rank system when he awarded shodan to two of his senior students (Shiro Saigo and Tsunejiro Tomita) in 1883. Even then, there was no external differentiation between yudansha (black belt ranks) and mudansha (those who hadn't yet attained black belt ranking). Kano apparently began the custom of having his yudansha wear black obi (belts) in 1886. These obi weren't the belts karateka and judoka wear today -- Kano hadn't invented the judogi (Judo uniform) yet, and his students were still practicing in kimono. They were the wide obi still worn with formal kimono. In 1907, Kano introduced the modern judogi and its modern obi, but he still only used white and black belt ranks.
Professor Kano was an educator and used a hierarchy in setting learning objectives for Judo students, just as students typically pass from one grade to another in the public school system. The Judo rank system represents a progression of learning with a syllabus and a corresponding grade indicating an individual's level of proficiency. Earning a black belt is like graduating from high school or college. It indicates you have achieved a basic level of proficiency, learned the fundamental skills and can perform them in a functional manner, and you are now ready to pursue Judo on a more serious and advanced level as a professional or a person seeking an advanced degree would.
Around 1930 Jigoro Kano created a new belt to recognize the special achievements of high ranking black belts. Jigoro Kano chose to recognize sixth, seventh, and eighth degree black belts with a special obi made of alternating red and white panels (kohaku obi). The white color was chosen for purity, and red for the intense desire to train and the sacrifices made. The colors red and white are an enduring symbol of Japan, and they have been used in Judo since Jigoro Kano started the first Red and White Tournament in 1884. The kohaku obi is often worn for special occasions, but it is not required to be worn at any time and the black belt remains the standard for all the yudansha ranks. Jigoro Kano also created the optional red belt to recognize 9th and 10th degree yudansha.
Theoretically the Judo rank system is not limited to 10 degrees of black belt. The original english language copy (1955) of Illustrated Kodokan Judo, by Jigoro Kano, says: "There is no limit...on the grade one can receive. Therefore if one does reach a stage above 10th dan... there is no reason why he should not be promoted to 11th dan." However, since there has never been any promotion to a rank above 10th dan, the Kodokan Judo promotion system effectively has only 10 dans. There have only been 15 10th dans awarded by the Kodokan in the history of Judo.
Other colored belts for students who had not yet achieved black belt originated later, when Judo began being practiced outside of Japan. Mikonosuke Kawaishi is generally regarded as the first to introduce various colored belts in Europe in 1935 when he started to teach Judo in Paris. He felt that western students would show greater progress if they had a visible system of many colored belts recognizing achievement and providing regular incentives. This system included white, yellow, orange, green, blue, and purple belts before the traditional brown and black belts.
The Judo practice uniform and belt system eventually spread to many of the other modern martial arts, such as aikido and karate, which adapted them for their purpose. Karateka in Okinawa didn't use any sort of special uniform at all in the old days. The kyu/dan ranking system, and the modern karategi (modified judogi) were first adopted by Funakoshi in an effort to encourage karate's acceptance by the Japanese. He awarded the first shodan ranks given in karate to Tokuda, Otsuka, Akiba, Shimizu, Hirose, Gima, and Kasuya on April 10, 1924. The adoption of the kyu/dan system and the adoption of a standard uniform based on the judogi were 2 of the 4 conditions which the Dai-Nippon Butokukai required before recognizing karate as a "real" martial art. If you look at photographs of Okinawan karateka training in the early part of this century, you'll see that they were training in their everyday clothes.
Promotion requirements for each rank vary according to the sensei and the national organization that you are affiliated with. There is no worldwide standard for each rank, although it is generally accepted that a blackbelt has had many years of practice and can perform at least the nage-no-kata, the gokyo-no-waza and the newaza techniques. For further information about promotion requirements see your sensei.
Here's how to tie your belt, proper sizing for a judogi, and some information about where to get a judogi. Here is another article on Origins of the Karate Rank System and on Belt Colors and Ranking Tradition.
4 Judo technique
Nage-Waza (Throwing Techniques)
Nage-waza can be divided into two sub-categories, tachi-waza (standing techniques) and sutemi-waza (sacrifice techniques).
The techniques of tachi-waza are performed while standing and fall into one of three categories: te-waza (hand techniques), koshi-waza (hip techniques), and ashi-waza (foot or leg techniques). The primary part of his body that tori (the thrower) uses to throw uke (the one being thrown) determines what heading a particular tachi-waza technique will fall under.
The techniques of sutemi-waza involve tori dropping to the mat and using his downward momentum to help throw uke. There are two types of sutemi-waza: ma-sutemi-waza (back sacrifice techniques) and yoko-sutemi-waza (side sacrifice techniques). The former involves tori falling to his back to execute the throw. In the latter, tori falls to his side in order to throw uke.
Katame-Waza (Grappling Techniques)
The techniques of katame-waza are usually employed when both competitors have fallen to the mat but there are some katame-waza techniques that can be used while standing. Katame-waza consists of three general types of techniques: osae-komi-waza (hold down or pinning techniques), shime-waza (choke/stangle holds), and kansetsu-waza (joint locking techniques, specifically armbars).
Atemi-Waza (Striking Techniques)
The striking techniques of judo are never practiced outside of kata as forceful or improper technique could lead to serious injuries or death. Atemi-waza are classified as either ude-waza (arm strikes) or ashi-ate (leg strikes).
Randori (Free Practice)
Along with kata (the practice of forms), randori (free practice) is the primary way of practicing and perfecting judo techniques. In randori two judoka spar with each as they might in an actual match. They are allowed to execute almost any nage-waza or katame-waza technique they wish so long as they are careful not to injure their training partner. The use of atemi-waza is randori is prohibited. Also, a few particularly dangerous nage-waza and kansetsu-waza techniques are not permitted in randori or competition.
Kata (The Practice of Forms)
Kata (the practice of forms) are pre-determined movements that are used to instruct in the methods of defense and attack. Kata includes techniques from nage-waza, katame-waza, and atemi-waza. Atemi-waza can be safely practiced in kata because both tori and uke know what maneuvers will occur and can react appropriately.
