Sonny Chiba reprises his role from Champion of Death as Masutatsu Oyama, the historical founder of Kyokushin karate in Japan (Oyama makes a cameo appearance in the film as well). Chiba had studied martial arts under the real-life Oyama for several years. True to the film's title, at one point in the course of the narrative he battles a "bear", actually a human actor in a bear costume.
