Maruta Kudari (丸太下り), originally named Taki Kudari (滝下り), called Rapid Descent in English broadcasts, was the third obstacle in the first two SASUKE tournaments, however, with the introduction of Rolling Maruta and Yureru Hashi being relocated in SASUKE 3, it became the fourth obstacle in that tournament and SASUKE 4.
This obstacle was essentially the opposite of Taki Nobori, in which it consisted of five rotating drums that angled at forty-five degrees and the drums were also textured like a waterfall, resembling the name of the obstacle (Taki means "Waterfall" in Japanese). The most notable difference, however, was that the third drum was rotating on its own, probably to resemble the movement of a waterfall. When the obstacle's name switched with Taki Kudari, the design of the obstacle was also modified, now textured as logs, which is the same case of when Taki Nobori's name changed to Maruta Nobori. The third log also no longer rotating on its own.
Competitors could either try to make a huge leap from the top of the obstacle (faster but riskier) or climb down the drums/logs one by one like climbing down a staircase (slower but safer). Most opted to go by the former strategy, as the more contact time with the drums/logs, the more chance for the competitors to fail at the obstacle.
Despite doing a fair amount of damage, when Kanzenseiha was achieved by Akiyama Kazuhiko in SASUKE 4, this obstacle was replaced by the more harder and iconic Jump Hang, though it would later return in SASUKE 31, for which it was combined with Maruta Nobori to create a new obstacle known as Rolling Hill.
