Jinmenken

Jinmenken are dogs, but with human faces that supposedly appear at night in Japanese urban areas and run along highways at extremely fast speeds. 

The jinmenken can also talk, but reports say that they will either be rude or will ask to be left alone. Unlike most Japanese urban legends, the human-faced dog is not widely known to kill those unlucky enough to meet it, though they are said to be escaped scientific experiments or the spirits of road crash victims. 

There is also speculation that witnesses who say they have met a jinmenken have actually come across Japanese macaques, which accounts for the quadrupedal movement, dog-like fur, human face and the human-like noises the jinmenken can supposedly make.
