Cain was born Dean George Tanaka on July 31, 1966, in Michigan. His biological parents are Sharon Tanaka and Roger Tanaka but the story of who raised Cain is interesting.
His biological father abandoned his family just after two years of marriage to Cain’s mother. When he was three years old, however, his mother moved on and remarried. She married director Christopher Cain, who legally adopted both Dean Cain and his brother.
