In appearance, judo is wrestling in jackets. It is the educational values and philosophy which make judo different. At the start, the techniques of judo are studied. Both children and adults learn how to fall safely, how to throw, how to pin down and for adults only how to strangle and armlock. Some of the theory behind the moves, to ensure safety, is also taught to the student. Safety is considered paramount. All students learn the Japanese name for each technique, and they practise in a relaxed and non-competitive way (randori).
At this stage, judo is just play where the students, wearing the well-known white jackets and trousers strive to safely apply their knowledge against an opponent who is doing the same, and generally have fun.
