Interesting note on shoot wrestling, it's basically Catch wrestling under rules that don't use pins and do use strikes. Guys like Karl Gotch, Billy Robinson and some others, basically Catch Wrestling masters, trained Fujiwara, Inoki, Funaki, Satoru Sayama and other Japanese pro wrestlers and some of them went on to form Shooto with Sayama (as well as Pancrase). Of course now it includes BJJ and Sambo because over the years the arts have intermixed a lot and now it's all just submission wrestling but soem small differences still exist.
