Koriki Chōshū (長州小力, Chōshū Koriki^?) (born Kazuteru Kubota (久保田和輝, Kubota Kazuteru^?), February 5, 1972 in the city of Nishi-Tokyo, Tokyo) is a Japanese comedian. He is most famous for his act in which he mocks a famous Japanese professional wrestler Riki Chōshū due to his resemblance. Koriki is a play on Riki's name, meaning something like "little Riki".

Unlike many Japanese comedians, he isn't associated with any entertainment agency, though he belongs to a comedian "pro-wrestling" organization, West Gate Wrestling Federation (西口プロレス, Nishiguchi Puroresu^?).

On Television, he is always seen wearing the same outfit, short bicycle shorts and a far too short T-shirt showing off his protruding belly. He speaks with a very strong lisp (much less so when not in character) and is prone to treating mundane objects (such as his microphone) as wrestling opponents.

As an acting pro wrestler, he uses appropriately strong language, though it's never taken seriously due to his strong lisp.

More recently, he has added Para Para (a Japanese dancing style) to his comedy routine, always to the tune of "Night of Fire", a popular Eurobeat track by Bratt Sinclaire. In 2005, riding the popularity of his act, Koriki was featured in a cover version of Niko's track with Para Para oriented Japanese idol group Hinoi Team, accompanying a video and CD release.
