Judo is a modern martial art that originated in Japan in the late 19th century. It focuses on using an opponent's strength and balance against them, allowing smaller or weaker individuals to defend themselves effectively. Practitioners, known as judokas, learn various techniques, including throws, pins, and joint locks, all while emphasizing respect and discipline. In Judo, competitions are held on a mat called a tatami, where judokas face off to score points by successfully executing techniques. The sport promotes physical fitness, mental focus, and self-confidence. Additionally, it teaches valuable life skills, such as perseverance and respect for others, making it popular worldwide.
