this at least improves the theoretical nihon wild grass code but it still doesn't work how I want it too...

I noticed that the PokeGear considers Route 49 and friends to be Kanto. Maybe there's a problem there?

But at the very least, by directly comparing to a landmark, everything should be fine...any brighter people who can help?

It's literally just making an if x then y work...
