The Maruta Nobori (丸太登り), referred to as the Barrel Climb on Ninja Warrior, was the first ever obstacle in the SASUKE tournaments. In the first competition, it was called as the Taki Nobori (滝登り), in which Ninja Warrior called as the Cataract Climb.
The obstacle consists of five rotating logs (or drums in the first competition) angled upwards at 45°, making it extremely slippery to traverse.
Without a good foothold, the logs will roll any competitor who lacks the skill for the Barrel Climb into the muddy waters below.
It is best to try and leap over the logs with two, long jumps, as more contact time with the spinning barrels equals failure.
