Wild Pig in Kobe

Kobe(神戸) is kind of strange place because of the wild pigs. People usually can't see wild pig in the other places, but it is pretty often to see the wild pigs in Kobe, especially Rokko(六甲), Mikage(御影), and Okamoto(岡本). Most of the time, the wild pigs appear during night time. I have never known the place that we can see the pigs like Kobe. Usually this kind of place is pretty rural region.
