I'm also be bothered by this issue. Firefox provides only 'ja' but trac i18n
only accepts ja_JP. I think it's strange and babel should fallback to accept
'ja' as 'ja_JP'.
It is good to provide locale data of ja_JP because it is explicit and has
detailed data.
But the country code of locale can be ommitted on requesting via Accept-Langage.
I'm using a patch for babel.core.negotiate_locale() localy to accept 'ja'.
