Hashimoto Kōji (橋本 亘司) is a sports instructor who was the one of the eight qualifiers in the SASUKE 21 Trials. In the trials, he cleared the "Final Stage" in 49.91 seconds, and managed to get the #7 qualifying spot.
During the tournament, he showed great speed, clearing most of the obstacles quickly. He reached the Soritatsu Kabe in great time, with about a minute left. However, he could not scale the wall and timed out there.
In the tournament, he wore #76 but his run was digested. It is shown that he made it to the Slider Jump and successfully reached the net. However, when he was moving down the net, his foot accidentally touched the water and he was disqualified. From what the announcer was saying, he had about 30 seconds left at that time, so he was in great position to clear the First Stage.
He then participated in the SASUKE 23 Trials, and for the third time became a qualifier for SASUKE 23.
In the tournament, he wore #47 but his run was digested. He was finally able to complete the 1st stage with 15 seconds remaining. In the 2nd stage, he completed the Downhill Jump with ease, but when attempting the Salmon Ladder he underestimated the distance between the first and second rungs, landed forcibly back on the first rung and lost his grip.
He then returned for SASUKE 24 and wore #85. There, he cleared the First Stage with 11 seconds remaining. Then, in the Second Stage, he cleared the Salmon Ladder that defeated him last time and the rest of the course. He then demolished the Third Stage, clearing every obstacle without any problems (he is one of the only three people to clear the Third Stage on their first try since SASUKE 4). In the Final Stage, he lost too much time on the Heavenly Ladder and even though he kept a fast pace on the G-Rope, he still timed out inches away from the button.
In SASUKE 25 Hashimoto drew #60 from the lottery. He cleared the First and Second Stages with little time to spare. In the Third Stage he progressed the furthest (along with Li En Zhi), failing to grab the third ledge of the new Ultimate Cliffhanger. He competed in SASUKE 26
