Maruta Nobori (丸太登り), originally named Taki Nobori (滝登り), called Cataract Climb (Taki Nobori)/Barrel Climb (Maruta Nobori) in English broadcasts, was the first ever obstacle appeared in SASUKE.
The obstacle originally consisted of five freely-rotating drums that angled at forty five-degree, making it slippery to traverse. The drums were painted like waterfall, resembling the name of the obstacle (Taki means "Waterfall" in Japanese). When the obstacle's name changed to Maruta Nobori, the design of the obstacle also modified, now using logs instead of drums. The obstacle's visual were also filled with logs design as opposed to empty visual in Taki Nobori.
This obstacle required a good foothold/fast recovery, as the drums/logs would roll when the competitors tried to reach the top of the obstacle. The best way to complete the obstacle was to try and leap over the drums/logs with two long jumps, as the more contact time with the drums/logs, the more chance for the competitors to fail at the obstacle.
