I don't think It is NYC. Or Japanese, i think it is a Mix of America and Japan, Judging by the actual REGION, I see a desert right after the City Huin, I also see that after the desert there is fairgrounds etc....Then Snowy mountains on each side. So I definetly think it may be a mixture, To date I think this region is the most diverse, with deserts, forests, and a Modern city as well as old, And even Mountains definetly not like our other regions at all I think.
