In spite the fact that it is introduced in SASUKE 19, no one reached the obstacle, as all 100 competitors failed the past stages, with the person who went the farthest only reached the Second Stage. However, TBS teased viewers by showing a tester fail there in the SASUKE 19 opening. Competitors have had good success on the obstacle, with only one failure, Miyazaki Daisuke, in SASUKE 21.
The obstacle was removed in favor of the Floating Boards after Urushihara Yuuji's kanzenseiha, but returned as the fifth obstacle on the Southwest qualifying course during American Ninja Warrior 4. Also, it used during the Northwest finals. It was used again on American Ninja Warrior 6 in Denver and American Ninja Warrior 7 in Pittsburgh.
This obstacle is a set of ascending and descending stairs where the competitor must climb under the steps to reach the next obstacle. There are three intervals of seven steps in total, with the first two going upwards, while the last one goes downwards.
While this obstacle was used on American Ninja Warrior, there were three differences from the SASUKE version. Firstly, the first, second, and third interval contained five, four, and nine steps, respectively (for a total of 18 steps, i.e. 3 steps less than the SASUKE version). Secondly, the gap between each interval and step was higher than the SASUKE version. Finally, unlike on SASUKE (where this obstacle has a high success rate), this obstacle was considered brutal, since several competitors ran out of energy from the previous obstacles and failed. On American Ninja Warrior 7 in Pittsburgh, the third interval was modified, with the third step was removed, and the sixth and seventh step were tilted 15 degrees, making it harder to maintain the grip.
