Hometown
Ono’s official site lists his place of origin simply as Kōchi, Japan. Public reference sources more specifically identify Sakawa, Kōchi Prefecture as his birthplace.
Career Highlights
Jotaro Kujo is one of Ono’s defining roles. Public filmography records show him voicing Jotaro across multiple major JoJo anime arcs and game projects, making him the core Japanese performer most audiences associate with the character.

Full Current Filmography
The list below is a documented, source-backed filmography summary based on Ono’s official website and public reference databases available as of March 25, 2026.

Dubbing / live-action dubbing
Ono’s official site also lists a substantial dubbing career, including Jim Gordon in Gotham, Steve Jobs in Steve Jobs, Finn Hudson in Glee, and additional foreign-film and TV dubbing roles.
Critical Reception
Ono’s public critical standing is unusually strong for a voice actor because it is supported by both major franchise visibility and formal awards recognition. His Seiyu Awards wins show that industry recognition did not come from a single breakout role alone; it was sustained across years of prominent work.
For Jotaro specifically, the strongest evidence of reception is durability. Ono is the actor carried across nearly every modern Japanese JoJo incarnation of the character, from Stardust Crusaders through Stone Ocean and multiple game adaptations. That consistency strongly suggests his portrayal became the franchise-standard Japanese voice for Jotaro. That final point is an inference based on the documented casting pattern across titles.

English Voice Actor: Matthew Mercer
Date of Birth
June 29, 1982. Public reference sources list Matthew Mercer’s birth date as June 29, 1982, and Behind The Voice Actors identifies his birthplace as Palm Beach Gardens, Florida, USA.
About Matthew
Matthew Mercer is an American voice actor, director, and producer best known for animation, anime dubbing, video games, and Critical Role, where IMDb describes him as a central creative figure and chief creative officer. In anime and game voice acting, he is especially associated with roles such as Jotaro Kujo in JoJo’s Bizarre Adventure, Levi in Attack on Titan, and Chrom in Fire Emblem.
Hometown
The clearest publicly documented origin point I found is Palm Beach Gardens, Florida, USA, which Behind The Voice Actors lists as Mercer’s birthplace. I did not find a stronger official hometown statement in the sources reviewed here, so I am treating birthplace as the most supportable public location reference.
Career Highlights
For JoJo’s Bizarre Adventure, Mercer is the English dub voice of Jotaro Kujo across the modern anime adaptation, including Stardust Crusaders, Diamond Is Unbreakable, Golden Wind, and Stone Ocean. Behind The Voice Actors identifies him as the actor who has voiced Jotaro the most often in English-language releases.
Outside JoJo, Mercer’s broader public profile is unusually large for an English voice actor because he is prominent in both anime and games. Behind The Voice Actors highlights Levi, Chrom, and Jotaro Kujo among his best-known roles, while IMDb emphasizes his work in voice acting alongside his role in building Critical Role into a major media brand.
Full Current Filmography
The list below reflects a source-backed documented filmography summary based on the public sources I checked as of March 25, 2026. Because Mercer’s credits are extremely extensive across anime, games, and original animation, and the available sources here were stronger on major roles than on a single normalized master credits list, this should be read as a documented current profile of major verifiable credits, not a guaranteed exhaustive filmography.
Anime / TV animation
2014–2015: JoJo’s Bizarre Adventure: Stardust Crusaders (Jotaro Kujo).
2018: JoJo’s Bizarre Adventure: Diamond Is Unbreakable (Jotaro Kujo).
2019: JoJo’s Bizarre Adventure: Golden Wind (Jotaro Kujo).
2021–2022: JoJo’s Bizarre Adventure: Stone Ocean (Jotaro Kujo).
Other publicly highlighted anime roles: Attack on Titan (Levi), along with other major dub and animation credits reflected in his public voice-acting profile. Behind The Voice Actors specifically identifies Levi as one of the roles he is best known for.
Video games
Documented major game roles highlighted by public sources: Chrom in the Fire Emblem franchise is one of Mercer’s signature performances, and IMDb also identifies him broadly as a major voice actor in games as well as animation. Because the sources reviewed in this turn were not a complete role-by-role gameography, I am labeling this as a documented major-games section rather than a full chronological master list.
Other screen / production work
IMDb identifies Mercer not only as an actor and director, but also as a producer, and describes him as playing a major executive and creative role within Critical Role. That makes his career broader than a standard dub-only résumé.
Critical Reception
Mercer’s public critical standing is driven less by a single dub-specific award narrative in the sources I reviewed and more by sustained cross-medium prominence. Behind The Voice Actors highlighting Jotaro Kujo, Levi, and Chrom as defining roles is a useful shorthand for how his voice-acting brand is publicly recognized.
For Jotaro specifically, the clearest reception signal is consistency and franchise durability. Behind The Voice Actors shows Mercer as the English actor most associated with Jotaro across the modern anime continuity, which strongly suggests his performance became the default English-language interpretation of the character for a large segment of the anime audience. That final sentence is an inference from the documented multi-series casting pattern.
