Judo, 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 maneuver, or force an opponent to submit by joint locking the elbow or by applying 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.

Judo is one of the few sports accessible to almost anyone, including children, adults, senior citizens, even people with disabilities. Because it emphasizes physical and mental development, its influence extends to every area of a person’s life. Physically, Judo improves flexibility, coordination, balance and reflexes. It is a means of self-defense that requires skill rather than just size or strength. Mentally, it promotes concentration, self-confidence and leadership. Because Judo requires a clear and focused mind, it encourages participants to be fully present in the moment. They become more observant and better able to channel their mental and physical energy. Judo participants benefit from practice, but just as important, they learn respect for others. With its strict moral and ethical principles, and its humanitarian approach to life, Judo fosters a sense of respect and consideration. Participants are taught to strive for physical, intellectual and moral perfection, so they can not only improve their own life, but also contribute to the greater good.
