Tetsurō Degawa

Tetsurō Degawa (出川哲朗^?, Degawa Tetsurō, born February 13, 1964, in Yokohama, Kanagawa) is a Japanese comedian.

Representative of the so-called "reaction entertainers," he is known for his thick voice. His favorite phrase is "Yabaiyo, yabaiyo!" (やばいよやばいよ!, It's dangerous, dangerous!), which has been mimicked by many co-stars. Degawa appeared on the 19th Sasuke competition, where he struggled on the first obstacle (the Sextuple Step) and failed on the second obstacle (the Log Grip).
