Jiu Jitsu originated in the United States in the South Bay (Torrance, Redondo, Manhattan Beach area of LA). It then spread from there throughout Orange County, San diego and the entire country. I am lucky enough to be from the South Bay area of LA where there is a ton of jiu jitsu including the original Gracie academy as well as Rigan Machado's academy. I then moved to San Diego for college. Haha two schools twenty minutes from my house have 5 black belts. Throwdown has Dean Lister as well as 4 other black belt instructors and Alliance MMA has Lovi, Leo Santos, and now Xande and Saulo Ribiero (don't be so mean). San diego= one of the best jiu jitsu and mma scenes in the country. That's just two of the schools there too...just check out one of the 500 "jiu jitsu in SD" threads
