Similar to the Godantobi and Rokudantobi, the Jūnidantobi is a set of eleven slanted planks, five on one side and six on the other, that competitors must jump across in order made it to the twelfth step, the finishing platform, hence the name. They are packed slightly closer together, and each log is angled slightly different to increase the difficulty.
Interestingly, unlike the Godantobi and Rokudantobi (when during the broadcast of Ninja Warrior, the obstacles were called Quintuple Step and Sextuple Step respectively), instead of Duodecuple Step (following the naming pattern), the Jūnidantobi was called Twelve Timbers during the broadcast of Ninja Warrior, although there were actually eleven timbers instead of twelve.
American Ninja Warrior Appearances
The Jūnidantobi appeared as the first obstacle in Stage One on American Ninja Warrior 5, replacing the Step Slider from the previous season, but was only called as the Timbers. Compared to the Jūnidantobi:
- There were only 8 steps instead of 11, and
- All the steps were angled the same way in this version (similar to the Godantobi or Rokudantobi).
Competitors' Success Rate
