I'd also appreciate information about superstitions connected to these areas and if there are special products the people living in these areas produce and/or sell to visitors and tourists.
Edit: Please no more mentions of Aokigahara! I've looked it up, but it doesn't fit what I'm looking for at all. My characters would never visit such a place. The area should have a reputation, yeah, but rather being known for having lots of classical stories and myths about ghosts, yokai and others connected to it.
