Googling did not seem to help, so assume many Dopers her will know.
My wife’s nephew in Tokyo only recently got into email. He may be the only Japanese guy who is not computer literate. Talking with him on the phone, we finally got him to give us his email address. The domain was .xx.xxxx, so tried sending him an email, but it bounced back. I suddenly realized that had to add an .JP to the end, and then sure enough it went through.
He tried to email us, but we never got it, so I am now thinking he probably has to put a .US on the end of our address. Correct? It would then be firstname.lastname@example.org.US, right?
As it is still night there, if this correct will send him another email telling him about that, and he should have the info by the time he gets up today (tomorrow?).
