Do you remember this word, Chou? I’ve explained it before on my blog (here is my previous post of Japanese slang “Chou” http://discover-jp.blogspot.com/2006_03_01_discover-jp_archive.html.)
On April 17th, new road markings, “Chou Kyuu curve (超急カーブ)” were appeared with white letters on a road in Tokyo. A high school student had an accident at the road before, and police suggested this marking and realized taking advantage of the incident.
“Chou Kyuu curve” means “really sharp bend in the road”. This is of course the first attempt to name “really sharp bend in the road” as “Chou Kyuu curve” with Japanese young people word.

I feel “Chou Kyuu curve” sounds too casual since “Chou” is informal word, and often used among young people. However, when I think suitable word for the road marking, I cannot find suitable one but using “Chou”… Probably, “Chou Kyuu curve” is the best marking to show how the road is sharp bend.
