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. NBC announced in September 2013 that it would air a special USA versus Japan series later that year wherein top American and Japanese competitors would go head-to-head on the Las Vegas Mt. Midoriyama course.
The fifth season of American Ninja Warrior premiered on June 30, 2013 on G4.
