Toonami significantly censors the anime, although it is mostly visible through the script change. Some aspects of the series such as the violence and other details such as Jotaro's underage smoking at not modified, and the uncensored blu-ray version is aired on TV. The series has a TV-MA V content rating, signifying that this program is intended to be viewed by mature, adult audiences and may be unsuitable for children under 17 mainly because of its violence. However, cases of nudity are censored. Jean Pierre Polnareff and Hayato Kawajiri's genitals are thus blurred.
The Toonami version mainly censors the original names and some of the profanities. Since many characters and Stands have names inspired by Western music bands in the original version, the American version changes several names to avoid legal troubles. Examples include Oingo and Boingo who become "Zenyatta" and "Mondatta", Killer Queen becoming "Deadly Queen", King Crimson becoming "Emperor Crimson" and so on. Shots that include a problematic name may have altered. For instance, a shot of a text mentioning Moody Blues has been changed to show "Moody Jazz". The anime also censors some of the strong profanities in the series. For instance in the Episode "The Faraway Journey, Farewell Friends", DIO's line comparing the Joestar Family to "dog shit on the street" was modified so that DIO says "You Joestars have always been a nuisance" instead; in the episode "Goodbye, Morioh - The Golden Heart", Kira's line about having a "rock hard boner" is beeped to prevent the sentence from being completely heard. In Golden Wind's American version, most of the profanities are said in Italian as well.
Some shots covered in Japanese text were also modified to remove the text.
