His extensive anime credits also feature appearances in JoJo's Bizarre Adventure as a scientist, Black Butler, One Punch Man, Attack on Titan, and The iDOLM@STER.

Beyond traditional anime, Nosaka has a prolific career in dubbing foreign films, television dramas, and video games into Japanese. His voice can be heard as the Japanese dub for David Madsen in Life Is Strange, Vladimir Makarov in Call of Duty: Modern Warfare III, and as a voice in Cyberpunk 2077 and Final Fantasy XVI. In the realm of live-action dubbing, he has contributed to the Japanese versions of major films such as Oppenheimer, the Jurassic World series, and Spider-Man: No Way Home, as well as television series like The Boys and Vincenzo.

A significant achievement in Nosaka's career is his versatility and his success in transitioning into a recognized supporting actor across multiple media formats, including documentaries, commercials, and even stage productions.
