Career
He is most famous as one half of the owarai duo Bakushō Mondai along with Yūji Tanaka, where he acts as the boke. Ōta is known for his strained, long-winded speeches, though it is perhaps his profound and sometimes dangerous comments that make him a staple of modern Japanese entertainment, and reflect his rather remarkable personality. As a boke, one is generally expected to fulfill a more ignorant comedy role, but Ōta"s boke has him frequently overstepping classical boundaries into new and often controversial territories, often prompting Tanaka (as the tsukkomi) to bring him back down to reality.
His opinions almost never synch with Tanaka"s, that is to say, he often avoids agreeing with Tanaka by intentionally taking the opposing side simply out of spite, making their boke/tsukkomi relationship much more lively, and perhaps realistic.
He is an active essayist and has published a number of collections. In 2010, Ōta published his first fictional literary work, a collection of short stories, "Maboroshi no Tori" (マボロシの鳥 / Legendary Bird) which he followed with a novel "Bunmei Number Ko" (文明の子 / Child of Civilisation) in 2012.
Ōta has recently found a niche for his relatively extremist and sometimes ridiculous world views as the main speaker in the Nippon television show, Hikari Ōta"s If I Were Prime Minister. Secretary Tanaka, where he acts as the Japanese Prime Minister and addresses various social problems with his own style of radical solutions.
Ōta also voiced Sid in the Japanese dubbed version of the computer-animated film Ice Age and Ice Age: The Meltdown.
