Takehito Koyasu (Japanese Voice Actor)
About Takehito
Takehito Koyasu is a veteran Japanese voice actor who has been active in the anime industry since the late 1980s. Over the course of his long career, he has built a reputation for voicing complex, often morally ambiguous characters with a smooth and commanding vocal delivery. His range extends from menacing antagonists to eccentric supporting roles, demonstrating a versatility that has kept him consistently in demand across decades of anime production.
His casting as Zeke Yeager is widely regarded as an excellent fit. Zeke is a character who projects calm authority and intellectual superiority, concealing deeper ideological convictions beneath a composed exterior. Koyasu’s naturally deep and measured voice captures this duality effectively, lending Zeke a sense of controlled menace that aligns with the character’s role in the story.
Beyond his work in Attack on Titan, Koyasu is perhaps best known internationally for his portrayal of DIO in JoJo’s Bizarre Adventure, a role that cemented his status as one of anime’s premier voices for sophisticated villains. He has voiced characters across a wide variety of genres, from action and fantasy to comedy and drama.
