Tadanobu Asano is a highly acclaimed Japanese actor whose career has been primarily defined by his extensive work in live-action film and television. Born on November 27, 1973, in Yokohama, he began his acting career at the age of sixteen and has since become an internationally recognized figure, known for his versatile and often intense performances in both Japanese and Hollywood productions. His live-action filmography is vast and critically celebrated, including notable roles in films such as Ichi the Killer, Zatoichi, Mongol, and as Hogun in the Marvel Cinematic Universe's Thor series.

While Asano's reputation is firmly rooted in live-action performance, his involvement in voice acting for anime is limited. His most prominent and well-documented role in the medium is in the 2009 science fiction action film Redline. In this animated feature, which took seven years to produce and was directed by Takeshi Koike, Asano provided the voice for the character Frisbee. Frisbee is depicted as the genius mechanic and friend to the main protagonist, JP. The film itself is noted for its entirely hand-drawn animation and features a cast that includes other prominent Japanese talents like Takuya Kimura and Yu Aoi. Asano's participation in Redline represents a collaboration with director Katsuhito Ishii, who wrote the original story for the film and with whom Asano had worked on several live-action projects, including The Taste of Tea and Funky Forest.

Beyond this significant voice role in Redline, Asano's filmography, as documented in major film databases, does not list other substantial credits for anime voice acting. His career continues to be focused on live-action roles, with his work as an actor, musician, and artist remaining his primary public and professional identity.
