Japanese Jiu-Jitsu is a traditional martial art that originated in Japan. It focuses on using an opponent's energy and movements against them, emphasizing techniques such as joint locks, throws, and grappling. This art form was developed by the samurai as a method of self-defense when they were unarmed or in close combat situations. Practitioners of Japanese Jiu-Jitsu learn to control and subdue opponents without relying on brute strength. The techniques are designed to be effective for individuals of all sizes, making it accessible to a wide range of people. Over time, it has influenced various modern martial arts, including Brazilian Jiu-Jitsu and Judo.
