The Chou Touhan (超登坂), called the Hill Climb (not to be confused with Sosoritatsu Kabe , which also shares the same name) on Ninja Warrior, was a Second Stage obstacle of the third and fifth KUNOICHI tournaments. It was a hill on a 50° incline, 5 meters long. The competitor had to simply reach the top. It didn't retire anybody thus it was replaced with the Sanrentobi in KUNOICHI 4 , but returned in KUNOICHI 5.

KUNOICHI 4 Version
The Chou Touhan also make its debut in KUNOICHI 4 as well, in the First Stage. However, a different version is used. It consisted of two sloped hill which the second hill is steeper thus having two ropes attached to it. This is proven to be a time waster as no one timed out there. Since Chou Touhan already make its debut in KUNOICHI 4, it has to replaced the Second Stage version thus Sanrentobi took its place.
