Kabuki mask? 

Being that actors in kabuki only very rarely, if ever, wear masks, I am curious as to the origin of this kabuki mask, and its appearance, if a nice clear picture can be found. Is it a Noh mask? Is it a mask made to look like kabuki makeup? Or is it completely unrelated to actual kabuki performances, and only sort of looks like some stereotypical conception of what kabuki makeup looks like? Thank you.
