Nakamura Satoshi's Salmon Ladder Disqualification

Nakamura Satoshi's Salmon Ladder Disqualification is a disqualification that occurred during SASUKE 23's Second Stage, where Nakamura Satoshi was disqualified for using his feet to touch the side of Salmon Ladder.

The introduction of Salmon Ladder in SASUKE 18 has greatly change the tone of Second Stage, with what used to be a Speed Stage, now acted more like mini-Third Stage, due to the purpose of Salmon Ladder that require upper body to clear the obstacle. It had caused problem and in this tournament, it was no different.

Disqualification
Nakamura was the fourth competitor to attempt Second Stage. Two fellow SASUKE Trials' Qualifiers, Tajima Naoya and Hashimoto Kouji, had previously failed Salmon Ladder. He showed great speed on the obstacle, but when transitioning from the sixth to seventh level, the bar went lopsided and he used his feet to hold himself on the obstacle, thus getting disqualified.

Aftermath
It is speculated that he admitted that he had made a mistake, thus wasn't offered a second run. Most people have seen this as proof that competitors not allowed to use their feet to touch the side of Salmon Ladder.

However, TBS themselves didn't make any modification to prevent further disqualifications in the future. It seemed that it is a rule since the beginning that the competitors are not allowed to touch the obstacle using their feet, hence probably the lack of the modification.
