Daisuke Ono
In Japanese, Jotaro was voiced by Jūrōta Kosugi in the OVAs, but has been voiced by Daisuke Ono since "". Ono first learned of the series when he was studying in college during his free time and came to enjoy the manga. He felt pressure when doing Jotaro's voice, stating that "Jotaro's a representative character of the series." The audition process for the "Stardust Crusaders" television series was separate from that of the game he previously worked on. Ono had to re-audition for Jotaro's character. He further said "Jotaro is a character who's cool and collected and on the verge of boiling over all at the same time. He takes those two contradictory elements and makes them work together at a high level."
