The next five Parts were gradually released over the next seven years, with the series reaching 50 volumes in total. The final volume of Stone Ocean was released on February 18, 2009.

On August 31, 2012, all 12 bunkoban volumes of Diamond is Unbreakable were made available digitally as the monochrome line of JOJO-D. the digitally released edition of the JoJo's Bizarre Adventure manga.

Volumes can also be downloaded to mobile devices through Shueisha's own Jump Store app for iOS and Android. Vento Aureo and Stone Ocean were made available in the following weeks, and Parts 1-3 were made available on September 21, 2012.
