Sadao Kujo
Also known as: Jotaro's Father
Sadao Kujo is Jotaro Kujo's father — a Japanese jazz-musician who married Holy Joestar in 1969. Largely absent across Stardust Crusaders due to his international touring career, Sadao is one of the franchise's most-discussed off-page parental-figure characters. His relationship to Jotaro is depicted with deliberate restraint — neither hostile nor romanticised — and his structural role across the arc is the Kujo family-name anchor that distinguishes Jotaro from the Joestar bloodline's standard naming convention.
Story
Stardust Crusaders
Part 3 · 1942–1989Sadao's pre-arc biography is depicted across one chapter as a Japanese jazz-musician with international-touring career obligations across the late 1960s and 1970s. He marries Holy Joestar in 1969 and they have Jotaro in 1970. His sustained-absence-from-Jotaro's-childhood is the structural reason Jotaro's pre-arc relationship with Joseph Joestar (his American grandfather) is closer than his relationship with Sadao. The manga depicts Sadao with deliberate restraint — neither hostile nor romanticised — and he survives Stardust Crusaders without on-page combat involvement.
