Judo is a form of wrestling used mostly in self-defense, and made popular by MMA tournaments such as UFC. It is based on a a knowledge of where the weak points in the human body are located. As a sport it is known as jujutsu or jujitsu. These are Japanese words, for it is most popular in Japan.
The object of judo is to kill or so injure an attacker as to make him completely defenseless. Judo was taught to men in the United States armed services during World War II so that they could defend themselves against enemy soldiers, especially the Japanese, in hand-to-hand combat.
A student of judo is taught how to press or strike various nerve centers and muscles of his opponent so as to temporarily paralyze him. Some of these centers are the solar plexus (just below the ribs), the Adam’s apple, the area behind the ear, and the upper lip. These centers are struck with the side of the hand, stunning the opponent and leaving him open for more direct attacks. Such attacks may often result in serious injury or even death due to damage of the nervous system, brain, and other sensitive areas of the body.
Jujutsu is a scientific way of wrestling. Balancing himself on his right hand, a Japanese expert places his opponent in a leg “scissors” while pulling him down and back with his left hand. He combines a throat-lock with an arm twist, and at the same time throws his opponent off balance by pushing his right foot into the knee.
Another important part of judo is to get your opponent off balance by striking or “clipping” him below the back of the knee with our leg, throwing him back and off his guard. There are various other ways of unbalancing the opponent, such as grasping the hand and quickly turning your back toward him, throwing him over your shoulder. This requires much practice and fast footwork. Such methods of attack make it possible for a small person to overcome a bigger person with little trouble. In fact, the weight of the bigger person is often a disadvantage to him, because the bigger he is the harder he falls.
Judo is often said to be a “dirty” form of jujutsu in which no holds are barred. Jujutsu was first developed by Chinese monks thousands of years ago to defend themselves against robbers. It was taken over by the warrior class of Japan, the samurai, who secretly passed it on from one generation to another. In modern Japan it is taught in schools to children in the form of physical training, and many Japanese soon became very good at it. The secrecy surrounding jujutsu has given many people the idea that it is the best method of defense and attack. However, a good wrestler can hold his own and even win over a jujutsu expert. Many jujutsu holds are used in modern wrestling and MMA.
