Shinoyama graduated from Nihon University. He worked with the Light Publicity agency while still a student, and freelanced after graduation.
Shinoyama has put out a large number of books of photographs of girls, dressed, mostly undressed, and nude.
On November 10, 2009 Shinoyama's home and office were searched by police on suspicion of public indecency. The searches stemmed from concerns regarding nude photos he allegedly took in public of two women in August 2008 for his book 20XX TOKYO. 
He is married to Saori Minami and their son is actor Akinobu Shinoyama.
