Judo is combat martial art and Olympic sport created in Japan in 1882 by Jigoro Kano. The main objective is to either throw or take an opponent to the ground, immobilize or otherwise subdue an opponent by pinning them to the ground, or force an opponent to submit with a joint lock or choke.

The style and philosophy developed for judo became the model for other modern martial arts and its popularity across the world has led to the development of a number of other amazing martial arts such as Sambo and Brazilian jiu-jitsu.
