Zomahoun Idossou Rufin (born June 15, 1964), popularly known as Zomahon (ゾマホン), is a Beninese foreign personality (gaijin tarento and diplomat) in Japan.
Until 2006, he was a student at Sophia University in Tokyo, where his coursework completed without a degree of Ph.D. in sociology.
In 1998, Zomahoun was "discovered" by a TBS executive and became a cast member on the TV show Koko ga Hen da yo Nihonjin.
In a pool of 100 foreigners voicing their displeasure about certain aspects of Japanese society, he was usually picked due to his hyperactive Japanese speech, causing him to trip over his words and prompting the celebrity panel to yell at him to speak more slowly.
In 2008, he participated in a few episodes (403-406) of Ainori reality show, when the traveling group arrived in Benin.
