The phone below has a Choose language menu in which you can choose your language from a multitude of languages and variants, including 日本語（アメリカ合衆国）:
QUESTION: Is there really an American Japanese language variant?
If yes, how different is it from Tokyo Japanese?
- The title of the dialog is Change language, and units/date format/first day of week/etc are covered by a different dialog.
- Another choice is Italiano (Sudafrica). Even though it might sound surprising, there actually is a variant of Italian in South Africa.
- A Google search shows that the
ja_USlocale seems to be used by quite a few people. Example taken from a technical mailing list (I don't imply that this person is right, I just say that this point of view exists):
you can configure Wine to display Japanese by using the LC_ALL enviroment variable. In the United States, set it to ja_US, and in Japan, set it to ja_JP. The reason for the localization difference is because programs compensate for the different dialects of a language across different nations (think en_US and en_GB, one for the US and one for England.)
