Sasuke

Sasuke is a Japanese sports entertainment reality television show that has been airing since 1997 in which 100 competitors attempt to complete a four-stage obstacle course. Failing any obstacle during a stage, or running out of time on stages with set time limits, leads to elimination. Finishing a stage by reaching the end and hitting the buzzer will grant advancement to the next stage. Sasuke also has many international versions of itself, mainly called "Ninja Warrior", with 20 local shows.
