Ihara Naoki is a sprinter who has competed twice on SASUKE. He made his debut in SASUKE 31, where he flew by most of the first stage, until he reached the Soritatsu Kabe. He had gotten worn out on the Tackle, and it took him three tries to get up the wall. Ultimately, he ran out if time on the Lumberjack Climb. Though it was all cut from the entire broadcast, his full run can be found on YouTube.
He returned in the next competition, where his run was digested, but it showed that he timed out once again on the Lumberjack Climb—at about the exact same spot as last time.
