Tadanobu Asano actor credit keeps getting declined

I have recently been trying to update the filmography of the great Tadanobu Asano with an early role which despite numerous submissions with backing evidence is getting declined. The film was itself added by me and everything was accepted but not Tadanobu - even though he is clearly on the cover art! I have provided multiple links including an interview were he even discusses the role! The film is Inochi Sasage Soro Yumeoizaka no Ketto. I have noticed this a few times i have tried to add credits that are declined. IMDB is pretty poor on Japanese cinema to begin with so its frustrating when factual credits are declined.
