This obstacle was composed of three cylindrical beams, all of which were about 150 centimeters long.
- The first beam was made of wood and was the most crooked of the three beams. There was a rope dangling halfway across to aid competitors in traversing.
- The second beam was completely rounded and was made of a much less sturdier material, bamboo. Similar to the first beam, there was also a rope dangling halfway across to aid competitors in traversing.
- The third and final beam was composed of steel, and had less supports than the previous two beams, with no rope to aid the competitors. Unlike the previous beams, once competitors set foot on the steel beam, it began to shake vigorously, making it the most difficult to traverse. This beam was the most hardest and deadliest, and every failure that occurred on this obstacle, happened there.
In the 8th tournament, this obstacle wiped out 3 of 8 competitors attempted it: Okamoto Sayaka (for the second time), Nakao You and Inoue Masumi. Despite good elimination rate, this obstacle wasn't brought back in the KUNOICHI 9's redesign course.
