It is many things to different people. It is a fun sport, an art, discipline, a recreational or social activity, a fitness program, a means of self defense or combat, and a way of life.
The first time judo was seen in the Olympics was at the 1932 Games in Los Angels, where about 200 judo students gave a demonstration. Judo became an Olympic sport for men in the 1964 games in Tokyo.
Judo, which means "gentle way" is a Japanese martial art based upon the ancient techniques of jujutsu that originated in Japan in the late 19th century. This sport is known for its spectacular throwing techniques but also includes numerous techniques for controlling an opponent while on the ground. Judo is often compared to freestyle wrestling and while the two share many techniques, it retains many dangerous self-defense maneuvers.
The worldwide spread of Judo has led to the development of a number of offshots such as Brazilian Jiu Jitsu. In Sao Paulo I saw some academies to learn Jiu Jitsu and Judo.
This is an uniform that people wear when they do Judo. The belt is usually coloured to indicate rank. In Japan, person who is in the highest rank has a black belt. The jacket is intended to withstand the stresses of grapping and is much thicker than that of a Karate uniform.
The color of ranking in Brazil is different from Japan, U.S, and Canada. Brazilian belt rankings are normally white, blue, yellow, orange, green, purple, brown, and black. Competitors are organised into two categories depending on grading; the first is from white to green and the second is purple through black.
I think most Japanse middle or high school students study how to do Judo in their P.E class. In my case, I practiced it when I was in 9th grade. It was very difficult to throw a person and it was very scary to be thrown. I remember it hurted a lot when I was thrown by my P.E teacher.
Judo is good to learn as you can protect yourself and to discipline yourself. I am glad with the fact that many people around the world like Japanese traditional sport, Judo.
