I disagree, Liberty has no more importance in New York, the word that is, yes there is the statue of liberty but just because the word is used for a random ticket does not nearly give enough proof its based on New York, there is by far, much more proof that it is based off that area in china people keep mentioning, and think about it;
Even if they based the new region off the USA why would they go from Japan to New York when places like California are much closer to Japan, all be it across the ocean. I mean each region is normally a bit of Japan so it makes sense since they have run out of Japan areas they cross over to China as its not far, but it would be redicously far to go oh we've done Japan now Eastern USA.
I'm pretty sure someone also posted before that Isshu's region is very random, with a city and desert very close, New York isnt like that?
