Judo (柔道, jūdō?), meaning "gentle way", is a modern Japanese martial art (gendai budō) and combat sport, that originated in Japan in the late nineteenth century. Its most prominent feature is its competitive element, where the object is to either throw one's opponent to the ground, immobilize or otherwise subdue one's opponent with a grappling manoeuvre, or force an opponent to submit by joint locking the elbow or by executing a choke. Strikes and thrusts (by hands and feet) — as well as weapons defences — are a part of judo, but only in pre-arranged forms (kata) and are not allowed in judo competition or free practice (randori).
“Before and after practicing Judo or engaging in a match, opponents bow to each other. Bowing is an expression of gratitude and respect. In effect, you are thanking your opponent for giving you the opportunity to improve your techniq“There are people who are excitable by nature and allow themselves to become angry for the most trivial of reasons. Judo can help such people learn to control themselves. Through training, they quickly realize that anger is a waste of energy, that it has only negative effects on the self and others.”
