The popularity of the American Ninja Challenge has led G4 to create an licenced version of SASUKE, from series distributor Tokyo Broadcasting System titled American Ninja Warrior, with all contestants from the United States and all play-by-play commentary in English. As of early August, 2009, the competition has been decided. The competition was filmed from Saturday, August 29th, 2009, through Tuesday, September 1st, 2009. For a list on the obstacles seen in American Ninja Warrior see List Of American Ninja Warrior Obstacles.
The filming took place at 2861 Los Feliz Blvd., Los Angeles, CA 90039, with G4 working in conjunction with Pilgrim Films & Television. Open Try-Outs were scheduled on both Saturday, August 29th and Sunday, August 30th, from 7 AM to 6 PM. Although the days are being used as Open Try-outs, participants have submitted entry videos through G4 to Pilgrim Films, and certain entrants have been called to schedule a specific Try-Outs for one of the two days.
Out of all the competitors that competed on the first two days on the first six obstacles, only those with the top 30 times would move onto the semi-finals. From there, the top 30 would run the full obstacle course with the top 15 moving onto the finals. The finals consisted of two training challenges. For the first,known as the Bungee Cinderstack, competitors had to haul ten cinder blocks across a 50 foot gap while being strapped to a bungee cord. For the second, competitors had to run an obstacle course consisting of an army crawl(Cargo Crawl), a balance beam while carrying a heavy barrel(Double Gallon Log), and running through tires(Twelve Tires). The top ten combined times were flown to SASUKE 23.
