I live in an American Naval Base in Japan. There's city life in front of me; urban life where I'm at, the sea to my left, and a bunch of mountains and forests to my right. Quite a mix..
First of all, there would be a bunch of water Pokemon, and Pelipper. Water Pokemon because of the ocean, and Pelipper because, well, Pelipper live near the sea too. Water Pokemon like Corphish/Crawdaunt, Magikarp, Finneon, basically, all those sea Pokemon. We see a lot of Jellyfish here too, so we'd probably see some Tentacool/Tentacruel, and maybe some Frillish. I doubt we'd see Jellicent, but if we did, they'd be there. Obviously. @_@
And then we'd see a lot of Pidove, Murkrow, and (What would classify as a hawk? It's either Pidgeotto, or Staravia? One of the two.). We see a lot of pigeons, a lot of crows, and a lot of hawks here. So there's our birds.
Japan is known for its cicadas, and that would mean one thing. Nincada.
And then we'd have those city Pokemon. Lots of those cats, Meowth probably the more predominant. Grimer, Trubbish. Some Snubbull, and maybe even Voltorb and Magnemite.
I'm not so sure about the mountains. I know we get wild boar up there, so maybe some Tepig, Phanpy, that sort? Graveler and Geodude, maybe some Timburr and Mankey. And I guess Rattata too.
I think that's it though. I can't really think of anything else that we'd see where I live.
