Sasuke is a Japanese TV show that features contestants running through timed obstacles courses. There are four stages and only three people have completed all four to achieve "total victory." It looks really cool and a nice test of athleticism. The male competition (Sasuke) seems to heavily challenge arm strength. The female version (Kunoichi) appears to focus more on agility as opposed to arm strength.
Some really cool videos: Makoto Nagano winning Sasuke and Ayako Miyake winning Kunoichi
