The history of Brazilian Jiu Jitsu like many martial arts is mired in myth and suspect record keeping. As a relatively modern art with its roots in Brazil and Japan, there is much speculation as to who the major players were in its origins and how the art developed. Several facts that are known is that in the early 20 th century a Judo/Kano Ju-Jutsu (interchangeable names during this time period) practitioner by the name of Mitsuyo Maeda (Conde Koma) traveled to Brazil. He was a prize fighter who also taught Kano Ju-Jutsu to supplement his income.
