The Kaiten Tsutsu (回転筒) was the third obstacle of the Second Stage from KUNOICHI 3 to KUNOICHI 5 and KUNOICHI 7.

Similar to the Burasagari Maruta, which was used during the First Stage in SASUKE 1 and SASUKE 2, and was also called as the Spinning Log during the broadcast of Ninja Warrior, competitors had to run across a log, which was 30cm in diameter and 3.8m in length to reach the landing platform. From KUNOICHI 5, the log was lengthened to 5 meters in length.

The design of the Kaiten Tsutsu would later be replicated for the Spinning Log on several SASUKE/Ninja Warrior's international formats (e.g. American Ninja Warrior, Ninja Warrior UK, Australian Ninja Warrior, SASUKE Ninja Warrior Indonesia, and SASUKE Vietnam).

In KUNOICHI 9, the Pipe Hold has a similar design with this obstacle, except competitors couldn't stand on top of the log. Also, the Broken Pipes from American Ninja Warrior 9 in Kansas City had a similar design with this obstacle.
