BTTheP: I agree that the change from "western myth" to "any myth" is a good one, western stands out more because it seems unlikely that such a figure would return to Japan rather than his country of origin.
LooneyToons: When I wrote that original entry, I was thinking specifically of the Norns -- Viking goddesses -- hanging out in Japan in ''AhMyGoddess''.
Tulling: Is it often the case that even though an anime does not feature Tokyo as such, Japan and japanese people will be featured to the exclusion of all else, even in context where it seems unlikely that it would be so. I am primarily thinking of the fact that magical girls and their supernatural enemies are normally found exclusively in Japan. Would that be a special case of this trope or a separate one?
{{Ununnilium}}: Still falls under this trope. Though there should be a supertrope for this and others (like BigApplesauce), which are basically "Only the home city/state/country of the writers ever has anything happen".
{{Tanto}}: WriterProvincialism, maybe?
Tulling: A good idea for a trope, though I believe CreatorProvincialism would fit slightly better. It is not necessarily the writer's idea that it should be so, they could very well be forced to do it like that by their superiors.
{{Ununnilium}}: ProvincialWorld?
Also, a comic-book variation on this: Earth is where cosmic events that affect the whole universe take place. Perhaps BigBlueSpeck?
{{Robert}}: That's not restricted to comics -- DoctorWho has done it repeatedly. Put it as one of the sub-tropes of the page; Tokyo/New York/London/Earth as the centre of the universe.
For the page name, provincial world doesn't quite seem to fit the trope. How about AudienceCentredUniverse?
Tulling: As you may have noticed, I have already started CreatorProvincialism. Feel free to add to/edit that.

{{thatother1dude}}: I have an idea for a page quote:
Tokyo is in Japan
I am in Japan
thus, I am in Tokyo

{{Mads}}: Does anyone else notice this in Western TV, but with California instead of Tokyo?
I guess there's ''Power Rangers'' where aliens always attack Angel Grove, and ''Sliders'' where sliding was invented in San Francisco, but nothing else comes to mind at the moment. --DocumentN
[=SenatorJ=]: Doc Brown from ''Back to the Future'' posited that the day of all the action that happens in Hill Valley, CA was some sort of "temporal junction point for the entire space-time continuum." Or that it was just coincidence.

* Lampshaded and partially subverted in ''{{Breakout}}'', when the protagonists spend half of part one attempting to get to Tokyo for just this reason. They fail, however.
Wikipedia was unhelpful in figuring out what the ''Breakout'' referred to is, so I'm cutting it for now.
