Yamaguchi Kōsuke

Yamaguchi Kōsuke (山口 康輔) is a finswimmer who has attempted SASUKE four times. He debuted in SASUKE 12, where he timed out at the Rope Climb and his run was all cut. After this he started to train in rope climbing and the results are showed, as he cleared the first stage in SASUKE 13. He was slow in the second stage, and he timed out before lifting the second wall of the Wall Lifting. In SASUKE 14, he once again cleared the first stage, this time with over 20 seconds on the clock. He cleared the second stage for the first time, managing to get revenge on the Wall Lifting with only 1.7 seconds left. In the third stage, he cleared the Rumbling Dice, but he landed poorly on the platform and fell into the water. After 9 years and 15 tournaments later, he made a final return in SASUKE 30. He sadly was all cut and failed the Hedgehog.

Trivia
* Every time he failed the first stage, his first stage run was all cut.

* He and Yamamoto Shingo are the only two contestants to ever fail the Rumbling Dice, with both about to complete the obstacle but failing to properly land on the platform.
