Sadao Kujo is a minor figure only alluded to in Stardust Crusaders. A celebrated Japanese jazz musician, he is the husband of Holy Kujo and the father of Jotaro, yet his endless touring keeps him entirely off the page throughout the whole story.
Sadao is never actually shown during Stardust Crusaders. Because his musical career keeps him constantly away on tour, the narrative references him without ever bringing him on-panel, and so his design goes undepicted.
Little of Sadao's temperament is spelled out in the manga. What defines him is an all-consuming dedication to performing, a commitment so total that he stays perpetually absent from his family rather than present in their daily lives.

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Sadao built a reputation as a noted jazz performer, though whether he had already earned that fame by the time he married Holy is left unclear. Through their union he became father to Jotaro and, in turn, grandfather to Jolyne. Holy's own father Joseph appears to think little of him, a coldness the story links to Joseph's dim view of Japanese people.
