Katsumi Kawahara

Shigeo is released from prison and immediately beaten up by some old associates, which results in him losing his memory. Kasumi, who just by chance happens to be the manager of a band, takes him in and discovers his talent for singing.

Produced by Hitoshi Matsumoto, Documental pits ten comedians against each other. The objective is to make each other laugh in a closed room. Each contestant brings a one million yen participation fee. The last person to stay in the room without laughing wins. The winner is awarded a 10 million yen prize and bragging rights as the funniest comedian.
