Although introduced in SASUKE 19, no one reached the obstacle as all 100 competitors failed by the Second Stage, although 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. Unlike on SASUKE (where this obstacle had good success), this obstacle was considered brutal, since several competitors ran out of energy and failed. 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.
On American Ninja Warrior 7, the obstacle was modified where the 4th step, 1st row and 5th step, 3rd row gets tilted to make an incline and the 3rd step has removed from the 3rd row.
