In the JoJo’s Bizarre Adventure anime, the Josuke Higashikata most viewers mean is the Part 4 lead from Diamond is Unbreakable. In the Japanese version, Josuke is voiced by Yuki Ono. In the English dub, the character is voiced by Billy Kametz. The official JoJo anime cast page lists Ono as Josuke, and English dub cast databases credit Kametz for the role.
Japanese Voice Actor: Yuki Ono
Date of Birth
Yuki Ono was born on June 22, 1984. His official website lists that birth date in the profile section.
About Yuki
Yuki Ono is a Japanese voice actor and singer best known for major anime and game roles across shonen, sports, fantasy, and character-driven ensemble series. His official website highlights Josuke Higashikata in JoJo’s Bizarre Adventure: Diamond is Unbreakable alongside other signature roles such as Taiga Kagami in Kuroko’s Basketball, Louis in BEASTARS, Kyosuke Kiryu in Yu-Gi-Oh! 5D’s, and Koga Oogami in Ensemble Stars.
For JoJo fans specifically, the most important credit is confirmed by the official Diamond is Unbreakable cast page, which lists 東方仗助 / Josuke Higashikata — 小野友樹 / Yuki Ono. That makes Ono the principal Japanese anime voice of Josuke in the best-known screen version of the character.
Hometown
His official website lists his birthplace as Shizuoka Prefecture, Japan.
Career Highlights
Ono’s documented career highlights include several high-profile lead and fan-favorite roles. His official site filmography names Taiga Kagami in Kuroko’s Basketball, Josuke Higashikata in JoJo’s Bizarre Adventure: Diamond is Unbreakable, Louis in BEASTARS, Kyosuke Kiryu in Yu-Gi-Oh! 5D’s, and Koga Oogami in Ensemble Stars, plus major game roles such as Gran and Lancelot in Granblue Fantasy, Locke Cole in Dissidia Final Fantasy NT, Hawkeye in Trials of Mana, and Tsuzuramaru in Ken ga Kimi.
He also has formal industry recognition. The official Seiyu Awards winners page shows that Ono won Best Supporting Actor at the 7th Seiyu Awards. That award is one of the clearest pieces of evidence for his standing in the Japanese voice-acting industry.
Full Current Filmography
The list below reflects documented credits shown on Yuki Ono’s official website. Because the site presents a selected filmography rather than a complete database of every role, this should be read as an official source-based credit list, not an exhaustive record of every performance in his career.

Kuroko’s Basketball — Taiga Kagami.
JoJo’s Bizarre Adventure: Diamond is Unbreakable — Josuke Higashikata.
Yo-kai Academy Y: Encounter with N — Bakeira, Kengo Benimaru.

Critical Reception
The strongest reliably documented measure of Ono’s critical reception is his Seiyu Awards recognition. The 7th Seiyu Awards officially named him Best Supporting Actor, which indicates that his work had already earned broad professional respect early in his rise as a major anime performer.
His official profile also shows why he remains so recognizable: he has been repeatedly cast in major franchise roles across anime, games, and tokusatsu. In practical terms, that pattern of recurring lead and standout supporting roles in series like JoJo, Kuroko’s Basketball, BEASTARS, and Yu-Gi-Oh! is strong evidence of sustained industry confidence in his range and screen presence. That last point is an inference based on the concentration of prominent roles on his official filmography.

English Voice Actor: Billy Kametz
Date of Birth
Billy Kametz was born on March 22, 1987. Multiple public sources, including his obituary and major cast databases, also record that he died on June 9, 2022, at age 35.
About Billy
Billy Kametz was the English dub voice actor for Josuke Higashikata in JoJo’s Bizarre Adventure: Diamond is Unbreakable. He was an American voice actor whose best-known anime and game roles also included Naofumi Iwatani in The Rising of the Shield Hero, Takuto Maruki in Persona 5 Royal, Ferdinand von Aegir in Fire Emblem, and Galo Thymos in Promare. Behind The Voice Actors and IMDb both identify him as a Los Angeles-based actor originally from Hershey, Pennsylvania, who came to California after performing as Aladdin in Disney’s Aladdin: A Musical Spectacular.
For JoJo readers, the key answer is direct: Billy Kametz is the English voice of Josuke Higashikata in Diamond is Unbreakable. That role remains one of the performances most closely associated with his name.
Hometown
Public sources describe Kametz as originally from Hershey, Pennsylvania, and his obituary states he was born in Lancaster, Pennsylvania. Because “hometown” can be defined differently across sources, Hershey is the most consistently documented place associated with his upbringing and public biography.
Career Highlights
Kametz’s most prominent documented roles include Josuke Higashikata in JoJo’s Bizarre Adventure: Diamond is Unbreakable, Naofumi Iwatani in The Rising of the Shield Hero, Takuto Maruki in Persona 5 Royal, Ferdinand von Aegir in Fire Emblem, and Galo Thymos in Promare. Behind The Voice Actors specifically highlights Josuke, Naofumi, and Takuto Maruki among his signature parts.
He also received major award recognition. Crunchyroll’s 2020 Anime Awards named him Best VA Performance (English) for his work as Naofumi in The Rising of the Shield Hero.
Full Current Filmography
The list below reflects documented credits from publicly accessible sources, mainly Behind The Voice Actors and IMDb. Because those databases can differ and posthumous credits may be updated over time, this is a documented-credit filmography and may not be exhaustive.

Stage work
Before his voice-acting breakout, Kametz performed on stage and later moved to California to play Aladdin in Disney’s Aladdin: A Musical Spectacular during the show’s final year. That stage credit is one of the most consistently cited facts in his professional bio.
Critical Reception
Kametz’s strongest formally documented recognition is his 2020 Crunchyroll Anime Award win for Best VA Performance (English) as Naofumi in The Rising of the Shield Hero. That award gives a clear benchmark for how highly his work was regarded by fans and industry-facing anime media.
Beyond awards, his reputation is reflected in the kinds of roles repeatedly tied to his name: JoJo lead Josuke Higashikata, Persona 5 Royal antagonist-counselor Takuto Maruki, Fire Emblem’s Ferdinand von Aegir, and Promare’s Galo Thymos. Those are major franchise parts rather than one-off minor credits, which strongly suggests he was viewed as a dependable lead and standout supporting performer in English anime dubbing. That final point is an inference based on the prominence and recurrence of his credited roles.
