When fans hear the iconic, stoic growl of the Joestar family's most famous delinquent, they're listening to a masterclass in modern voice acting. Matthew Mercer brings the English dub of Jotaro Kujo to life across multiple seasons of JoJo's Bizarre Adventure. Capturing a character as emotionally guarded and commanding as Jotaro requires a rare blend of gravity, precise comedic timing, and raw vocal power.
Finding the right voice for a cultural touchstone isn't easy. While the original Japanese performance by Daisuke Ono set a high bar, Mercer carved out a distinct identity for the English version. Let's break down how this performance shaped the character, the career milestones of the actor behind the hat, and what makes this dub adaptation stand out.
Who Voices Jotaro Kujo in English?
Matthew Mercer is the definitive English voice actor for Jotaro Kujo. He voices the stoic protagonist across Stardust Crusaders, Diamond is Unbreakable, Golden Wind, and Stone Ocean. Mercer is a massive name in the voice acting industry, known not just for anime, but for co-founding the massively popular tabletop roleplaying show Critical Role.
Stepping into Jotaro's shoes meant portraying a teenager—and later a marine biologist—who rarely raises his voice yet commands every single room he enters. Mercer adopted a low, gravelly register that matches the character's unbothered posture and brutal efficiency in battle. He didn't try to mimic Ono's Japanese performance note-for-note. Instead, he leaned into his own vocal strengths, giving Jotaro an Americanized swagger that fit the late-1980s aesthetic of Part 3.
The Vocal Challenge of Stardust Crusaders
Playing Jotaro Kujo comes with unique physical demands. The character spends a significant portion of his screen time shouting specific battle cries, most notably his famous "Ora Ora Ora" barrage alongside his Stand, Star Platinum.
Sustaining those throat-shredding sequences without causing long-term vocal damage requires intense technique. Voice actors in action anime often record battle cries in dedicated pickup sessions to protect their vocal cords. Mercer used a chest-heavy projection style that gave the punches real weight, ensuring the English dub matched the kinetic energy of the animation.
Beyond the combat, Jotaro's dialogue is defined by dry sarcasm and deadpan dismissals of absurd situations. Delivering lines like "Good grief" (Yare Yare Daze) requires precise deadpan timing. If a voice actor plays it too goofy, it ruins the cool factor. If they play it too seriously, it becomes boring. Mercer struck a balance that kept fans invested across hundreds of episodes.
Matthew Mercer Beyond JoJo's Bizarre Adventure
To understand why Mercer fits Jotaro so well, it helps to look at his broader career. He's spent decades anchoring major projects in gaming and animation. Some of his most notable credits include:
- Levi Ackerman in Attack on Titan (select video game and promotional materials)
- McCree / Cole Cassidy in Overwatch
- Trafalgar Law in One Piece
- MacCready in Fallout 4
- Ganondorf in The Legend of Zelda: Tears of the Kingdom
This extensive background in playing tough, morally gray, or world-weary heroes gave Mercer the exact toolkit needed for Jotaro. He understands how to inject subtle warmth into a character who acts outwardly cold.
Comparing English and Japanese Performances
Diehard anime fans often debate whether subbed or dubbed versions are superior. In the case of Jotaro Kujo, both Daisuke Ono and Matthew Mercer deliver top-tier performances, but they approach the role with different textures.
Ono's portrayal leans slightly heavier into theatrical anime intensity while maintaining a deep, resonant coolness. Mercer's performance feels grounded in Western action archetypes, sounding like an 80s movie action star trapped in a bizarre supernatural mystery. That subtle shift made the English adaptation accessible to viewers who prefer native-language dialogue without losing the intimidating aura that defines the character.
Common Misconceptions About Jotaro's Voice Cast
Fans frequently mix up voice actors across different parts of the franchise, especially given the rotating cast of protagonists.
One common error is assuming the same actor voiced Jotaro in all video game adaptations prior to the anime. Before the modern anime adaptation started airing, various video games and older OVAs featured different voice talents, such as Crispin Freeman in certain early fighting game appearances. However, once the official David Production adaptation began, Mercer secured the role and has remained the definitive English voice ever since.
Another mix-up involves confusing Jotaro with other Joestar family members like Josuke Higashikata or Giorno Giovanna, who have entirely different voice actors leading their respective arcs.
