Luckily for me, I was able to register without using a Japanese phone number and all that. I think the rule was changed a short while after I originally got it two years ago, so unless you can get a Japanese e-mail, I don't think you can register for mixi now. I've sent out friend requests before, but after that rule, despite having the friend invite, they still had to get a Japanese mobile number/e-mail in order to register it.
