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 major difference between this and Burasagi Maruta is that the log was connected directly to the two platforms, instead of being placed on a higher elevation connected by bars, thus eliminating the sliding method existed in latter one. The design of the Kaiten Tsutsu would later be replicated for the Spinning Log on several SASUKE/Ninja Warrior's international formats.
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.
