Aired: 2002-

"From the Land of the Rising Sun, 100 determined athletes have accepted the challenge to become NINJA WARRIOR." Think you're in decent shape? Think again, couch bunny. The competitors on this imported competition (it started in Japan in '97, but G4's been airing it here since '02) go through obstacle courses that make American Gladiator look like fucking minigolf.

Ninja Warrior is known as Sasuke in Japan, and is shown in 18 other countries.
