The Butterfly Wall (バタフライウォール) was a First Stage obstacle, firstly introduced as the second obstacle in SASUKE 14, and then appeared again in SASUKE 15.

In order to advance, competitors had to jump and grab onto a padded wall that spun around a central vertical axis to reach the platform on the other side. Only six competitors failed on this obstacle in its two tournaments span, and was removed in the next tournament.

American Ninja Warrior 8's Butterfly Wall in Stage Two

The Butterfly Wall appeared as the fourth obstacle in Stage Two from American Ninja Warrior 6 to American Ninja Warrior 8, replacing the Balance Tank from the past two American Ninja Warrior seasons. However, there were several differences between the Butterfly Wall used on American Ninja Warrior, compared to the one used in SASUKE:

  • The rotating wall was shaped more like butterfly wings with rounded corners and inclined ledges.
  • The wall was situated much higher up in relation to the starting platform, requiring a more accelerated and higher jump.
  • Competitors must time their release from the wall to grab a rope, then climbed it up (in a similar fashion with the Rope Climb), and finally dropped down to the landing platform.

It took out any competitor who was shorter than average, or had a bad run-up. On American Ninja Warrior 6, only two competitors failed on this obstacle (Yen Chen and Josh Cook). During USA vs. The World, Morimoto Yūsuke failed on this obstacle due to his shorter height, as he could not reach the top of the wall.

On American Ninja Warrior 7, the wall was placed lower than the previous season (from 8 feet to 6 feet). As the result, no competitor failed on this obstacle.

On American Ninja Warrior 8, the distance between the starting platform and the wall was made bigger than on American Ninja Warrior 6 and 7. Therefore, a trampoline was added to the starting platform. Despite that change, no competitor failed on this obstacle once again.

Because of its high success rate, this obstacle was replaced by the Swing Surfer on the next season.
