Last time I was in Japan half a year before covid I finally saw at least one and possibly two tanuki, also known as "raccoon dogs". They are not related to raccoons but have a very superficial resemblance due to dark areas around their eyes.
When I showed the blurry photo I got of a tanuki to a local they said it might be an araiguma. I had to look it up and when I found out it means "raccoon" I thought we had a language barrier/misunderstanding. But when I looked into it on the internet, it turns out that Japan actually has a big problem with feral raccoons!
Now I've been to Japan over ten times, from Okinawa to Hokkaido, and I've seen itachi, tanuki, kitsune, and shika, possibly also some others. But I've never seen a raccoon here. (I haven't seen a kuma or inoshishi in the wild either, but that's probably a good thing.)
My plans are flexible I could be anywhere in Japan in the next 2.5 months. Where could I go to increase my chances of seeing raccoons here?
