There is a Ninja Area being planned that has an Asian theme to it that will sell many Asian items. You can always upload a Japanese head/body to the server. You can set the Japanese flag in your profile, and I'm pretty sure you can buy a Japanese olympic flag. The guild #1 in the leaderboards is also Japanese. It's not like Japan is apparent anywhere in iEra.
We can't add an area for specific countries, because we can't make it seem like we favor certain countries over others that get left out, and if we added this than every single person from every single country would want an area for their country.
here and there
