Unfortunately I am very poor and cannot afford such an expensive camera, so I don't really know if this one comes with it in the appropriate language.
However, since I am otherwise a very clever fox, I had a quick look around at the manufacturer and found for you the Italian support page for the Nikon D810, where you can download the manual in Italian (and other software and the latest firmware):
