I had this happen in Nara, too, and they did have antlers at that time. Not only did they mob me, but one of them popped my right in the eye with his antler (I'm really short). Then he grabbed my sisters purse and grabbed a plastic luck charm out of it and chewed it all to pieces. They were still cute, though. We also saw people running and crying.
