I believe the boxes for the first image say (from top to bottom):
Mail Address
Password
Password (I can't read kanji, but I think it's safe to assume it's something saying to confirm your password)
License Key
The boxes in the second image are:
Mail Address*
Mail Address (confirm)
Username
Password
Password (confirm)
Serial Key
*: again, can't read kanji, but I'm gonna assume it's nothing important. Don't sue me if I'm wrong, though.
