Maruta Nobori

Maruta Nobori (丸太 登り), originally named Taki Nobori (滝 登り), was the first ever obstacle appeared in SASUKE.

The obstacle originally consisted of five freely-rotating drums that angled at 45°, making it slippery to traverse. The drums were textured like waterfall, resembling the name of the obstacle (Taki means Waterfall in Japanese). However, when the obstacle's name changed to Maruta Nobori, the design of the obstacle was also modified, now textured as logs.

This obstacle required a good foothold or fast recovery, as the drums/logs would roll when the competitors tried to reach the top of the obstacle. The best way to clear 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.
