The Japanese Ninja Warrior obstacle course contains 4 stages.
Stage one is all about speed and balance. Get to the end within the time allotment, without falling.
Stage two also has a time limit which varies in length depending on how challenging the obstacles are. The final three challenges are always the same: Three doors, each heavier than the last, leading to the final timed buzzer.
Stage three is different as there is no time limit. Instead, there are a series of exceedingly difficult obstacles that focus heavily on upper body strength and grip strength.
Few contestants have reached the fourth and final stage. In this stage the contestants must scale a 40 foot wall and a 30 foot rope in a mere thirty seconds. Only two individuals have ever completed the course.
