In the Japanese version of JoJo’s Bizarre Adventure, young Joseph Joestar is voiced by Tomokazu Sugita. In the English dub of the 2012 anime adaptation, young Joseph is voiced by Benjamin Diskin. For older Joseph in later arcs, the casting changes, but Sugita is the Japanese actor most associated with Joseph overall across Battle Tendency and several game appearances.

Career Highlights
Joseph Joestar is one of Sugita’s best-known anime roles. JoJo-focused sources identify him as the Japanese voice of Joseph in the first season of JoJo’s Bizarre Adventure: The Animation, and Behind The Voice Actors lists him as the performer who has voiced Joseph the most often in Japanese-language releases. That includes Battle Tendency and several game appearances.
Outside JoJo, Sugita’s career highlights include Gintoki Sakata (Gintama), Kyon (The Melancholy of Haruhi Suzumiya), Gyomei Himejima (Demon Slayer), Yusuke Kitagawa (Persona 5), Chrom (Fire Emblem), and Taro Sakamoto (Sakamoto Days). Public profiles consistently frame him as a major modern seiyuu known for a deep, distinctive voice and strong comic timing.
Full Current Filmography
The list below is a source-backed documented filmography summary based on public sources available as of March 25, 2026. Because Sugita’s full credits are extremely extensive and the sources checked here were stronger on major roles than on a single normalized master list, this should be read as a documented current profile of major verifiable credits, not a guaranteed exhaustive filmography.
TV anime
2000s major documented credits: Chobits (Hideki Motosuwa), Kanon (Yūichi Aizawa), The Melancholy of Haruhi Suzumiya (Kyon), Gintama (Gintoki Sakata), Shuffle! (Rin Tsuchimi).
2012: JoJo’s Bizarre Adventure (Joseph Joestar). JoJo-focused sources specifically identify Sugita as Joseph’s Japanese actor in the first season, and note he also voiced old Joseph in Episode 26 and in All-Star Battle.
2010s additional headline credits: Assassination Classroom (Tadaomi Karasuma), The Seven Deadly Sins (Escanor), and continuing franchise work in Gintama.
2020s documented major credits: Demon Slayer (Gyomei Himejima), Sakamoto Days (Taro Sakamoto), plus continuing voice work across anime, games, dubbing, and narration.
Video games
Public sources also document Sugita in major game roles such as Ragna the Bloodedge in BlazBlue, Yusuke Kitagawa in Persona 5, Chrom in Fire Emblem, and Joseph Joestar in JoJo’s Bizarre Adventure: All-Star Battle, Eyes of Heaven, J-Stars Victory Vs+, and All-Star Battle R.
Dubbing / narration / other work
AGRS states that Sugita also works widely in foreign-language dubbing and narration, with the agency specifically highlighting his dubbing role as Komaram Bheem in RRR in addition to his anime career.
Critical Reception
Sugita’s public standing is strong both from franchise visibility and industry recognition. Public sources note that he has been recognized at the Seiyu Awards, and his career profile shows sustained prominence across anime, games, and dubbing for more than two decades.
For Joseph specifically, the clearest reception signal is casting durability. Behind The Voice Actors lists Sugita as the Japanese actor who has voiced Joseph the most often, which strongly suggests his performance became the franchise-standard modern Japanese interpretation of young Joseph Joestar. That final sentence is an inference from the documented multi-title casting pattern.

English Voice Actor: Benjamin Diskin
Date of Birth
August 25. Behind The Voice Actors publicly lists Benjamin Diskin’s birth date as August 25 and his birthplace as Los Angeles, California, USA. In the sources I checked for this response, I did not find a reliable official source confirming a birth year, so I’m not stating one as verified here.
About Benjamin
Benjamin Diskin is an American actor and voice actor known for work in anime dubbing, Western animation, and video games. Behind The Voice Actors currently highlights Joseph Joestar, Numbuh 1 / Nigel Uno, and Ban among the roles he is best known for, while IMDb describes him as having nearly 30 years of voice acting experience across games, anime, and animation.
For JoJo’s Bizarre Adventure, Diskin is the English dub voice of young Joseph Joestar in the first season of JoJo’s Bizarre Adventure: The Animation. JoJo Wiki specifically identifies him with that role in the English dub.
Hometown
The clearest publicly documented origin point I found is Los Angeles, California, USA, which Behind The Voice Actors lists as Diskin’s birthplace. I did not find a stronger official hometown statement in the sources reviewed here, so I’m treating birthplace as the most supportable public location reference.
Career Highlights
For JoJo’s Bizarre Adventure, Diskin is best known as the English voice of young Joseph Joestar in the first anime season. That is the role most relevant to this query, and public JoJo-specific sources tie him directly to it.
Outside JoJo, Diskin has a broad and high-profile voice career. Behind The Voice Actors highlights Joseph Joestar, Numbuh 1 / Nigel Uno, and Ban as signature roles, while public biographical sources also associate him with characters such as Eugene in Hey Arnold!, Sai in Naruto, Death Gun in Sword Art Online, Satoru Fujinuma in Erased, Knuckle Bine in Hunter × Hunter, and Jack in Beastars.
Full Current Filmography
The list below reflects documented publicly accessible credits I could verify from major reference sources as of March 25, 2026. Because Diskin’s credits are extensive and public databases do not always line up perfectly across platforms, this should be treated as a source-backed documented filmography and may not be exhaustive.
Anime / TV animation
JoJo-related credit: JoJo’s Bizarre Adventure: The Animation (Joseph Joestar). JoJo Wiki specifically identifies Diskin as the English dub voice of Joseph in the first season.
Other documented anime and animation roles highlighted by public sources: The Seven Deadly Sins (Ban), Naruto / Naruto: Shippuden (Arashi Fuuma, Sai), Sailor Moon (Gurio Umino), Neon Genesis Evangelion (Kensuke Aida), Sword Art Online (Death Gun), Erased (Satoru Fujinuma), Hunter × Hunter (Knuckle Bine), Beastars (Jack), Aggretsuko (Haida), Digimon Fusion (Shoutmon, Cutemon), Stitch! / Stitch & Ai (Stitch), Blue Exorcist: Shimane Illuminati Saga (Kinzo Shima), Pokémon Horizons (Larry), and MASHLE: Magic and Muscles (Dot Barrett). These titles are all reflected across the public profiles I checked, though not every source provides a fully normalized character-by-character chronology.
Video games
Public sources document major game work including young Xehanort in the Kingdom Hearts series, Jusis Albarea in The Legend of Heroes: Trails of Cold Steel series, Mega Man in Mega Man 11, Lorenz Gloucester and Caspar von Bergliez in Fire Emblem: Three Houses, Victor in Mr Love: Queen’s Choice, Za’ji and other roles in The Elder Scrolls Online, Glenn Lodbrok in Final Fantasy VII Rebirth, and Black Doom in Sonic X Shadow Generations. Public reference sources also show continuing game credits into 2025.
Other screen / performance work
IMDb notes that Diskin has also appeared on screen as an actor, including work such as Kindergarten Cop, while public profiles emphasize that his career spans more than three decades across voice acting and live-action performance.
Critical Reception
Diskin’s public critical profile is driven more by sustained visibility and range than by a single award narrative in the sources I reviewed. Behind The Voice Actors highlighting Joseph Joestar, Numbuh 1 / Nigel Uno, and Ban as signature roles is a useful shorthand for how his voice-acting brand is publicly recognized.
One concrete award note does appear in the public biographical sources: Wikipedia states that Diskin won a Daytime Emmy Award in 2019 for his work on Muppet Babies. That supports the broader picture of him as a performer with substantial recognition beyond anime dubbing alone.
For Joseph specifically, the clearest reception signal is that public JoJo sources continue to identify Diskin directly with the English dub performance of young Joseph in the 2012 anime adaptation. Since Battle Tendency is the part that established Joseph’s anime popularity for many English-speaking viewers, that role remains one of the most search-relevant anime credits attached to his name. The final sentence is an inference based on the role’s prominence in JoJo-related public references.
