American Ninja Warrior
American Ninja Warrior is a sports entertainment competition spin-off of the television series Sasuke. The series began on December 12, 2009, in Los Angeles, with the top 10 competitors moving on to compete at "Mt. Midoriyama" in Japan. American Ninja Warrior succeeded G4's American Ninja Challenge as the qualifying route for Americans to enter Sasuke. Beginning with the fourth season in 2012, regional finalists and wild card competitors competed on an identical Mt. Midoriyama course in Las Vegas rather than traveling to Japan to compete on Sasuke.
