Takeshi Kitano (?? ?, Kitano Takeshi, b. January 18, 1947) is a Japanese comedian, actor, author, poet, painter, one-time video game designer and film director who has received critical acclaim, both in his native Japan and abroad, for his highly idiosyncratic cinematic work. With the exception of his works as a film director, he is known almost exclusively by the name Beat Takeshi (??????, B?to Takeshi). Since April 2005 he is a professor at the Graduate School of Visual Arts, Tokyo National University of Fine Arts and Music.

Kitano's films are usually dramas about Yakuza gangsters or the police, referred to by critics as being highly deadpan to the point of near-stasis. He often uses long takes where nothing appears to be happening, or with edits that cut immediately to the aftermath of an event. Many of his films express a bleak or nihilistic philosophy, but they are also filled with a great deal of humor and remarkable affection for their characters. Kitano's films paradoxically seem to leave controversial impressions. While formally disguised as dark comedies or gangster movies, his films raise moral questions and provide food for thought. While Kitano's international fame continues to rise sharply, the Japanese public knows him primarily as a TV host and comedian. His portrayal of Zatoichi in the 2003 movie by the same name is said to be his biggest domestic commercial success. During interviews, Kitano is careful to hide his enigmatic personality behind the mask of being a comedian and regular guy. He hosts a weekly television program called Beat Takeshi's TV Tackle (???????TV????), a kind of panel discussion among entertainers and politicians regarding controversial current events. But Kitano's primary role is to provide comic relief and he rarely shares his true feelings regarding controversial social issues. Although he interviewed Sh?k? Asahara, founder of the controversial Japanese religious movement Aum Shinrikyo, on at least two occasions (a fact little known outside Japan), his attitude towards religion is unknown. However, he displayed strong public feelings on one occasion, severely vandalizing an office of the Japanese tabloid Focus after it printed a story about an extra-marital affair.
