Jigoro Kano sent many of his students outside Japan to demonstrate and teach judo. Among these students, Mitsuyo Maeda and Mikonosuke Kawaishi went to the United States of America. After a long trip across the North and South America, Maeda finally settled in Brazil where he started to teach the Gracie family in the late 1910s/early 1920s a form of judo called Kosen Judo which is mainly focused on ne-waza (ground techniques). The Gracie family building on Maeda's legacy developed a system that would later become known as Gracie Jiu-Jitsu (or Brazilian Jiu-Jitsu).
