Suzuki Matsuo was born on December 15, 1962, in Kitakyushu, Fukuoka Prefecture, Japan. He is a multifaceted Japanese artist, widely recognized for his work as a theatre director, actor, novelist, and screenwriter, in addition to his voice acting roles. His career is primarily centered on stage and live-action film, where he has directed and acted in numerous projects. For instance, he has directed films such as Otakus in Love and Welcome to the Quiet Room, and has acted in live-action features like Ichi the Killer and Shin Godzilla.

Within the realm of anime, Matsuo has taken on a select number of voice acting roles. One of his most recognized performances is as Ludman in the 2019 3D CG anime film Dragon Quest: Your Story. In this adaptation of the Dragon Quest V video game, he voiced the character known as Rodrigo Briscoletti in the English version of the game. Another notable anime role early in his career was providing the voice of Kamon Nandaba in the influential 2000 OVA series FLCL. He also voiced the character Salvatore Bianco in the 2017 anime special The Dragon Dentist.

Matsuo's involvement in anime voice work appears to be occasional rather than a primary focus of his career, and there is no readily available information pointing to recurring collaborations with specific anime directors or studios across his voice roles. His contributions to anime are part of a much broader and more extensive career in Japanese entertainment as a creator and performer.
