Question: how is josuke a jojo?
Answer: Why is Josuke a JoJo? Most JoJo's have the nickname JoJo because they're first and last name both has the word "Jo" in it, but Josuke's last name is Higashikata, which has no "Jo" in it, so being a JoJo now means you need Joestar blood or what? The kanji for "suke" can also be read as "Jo".
