Choshu is a Japanese comedian who is widely known for having “The most famous gut in Japan!” His debut on Sasuke was mostly a publicity stunt, but his audience didn’t seem to mind.
Koriki Choshu is clearly his stage name. What many Ninja Warrior fans may not know is that this comedian took on the persona of a former popular wrestler in the 80′s and 90′s named Riki Choshu. The similarity in the names Koriki and Riki is no accident. In Japanese, “Ko” means “little” when added as a prefix. In this case, Ko-riki simply means little Riki.
