Lol!
In summary, fanspace is completely seperate from tickebo. fanspace is Namie's fanclub whereas tickebo is just a concert ticketing site. You don't need to be a member of fanspace to get Namie's tickets, but you do need a tickebo account to apply for any of her lotteries since she exclusively sells them there.
Signing up through tickebo's English or Japanese site doesn't matter since your account will work on both.
Namie's tickets are digital. So if you win a lottery, tickebo will send you a link about 1-2 weeks before the concert date so that you can download the tickets to your account.
And if you're going with friends, they all need a tickebo account so that you can send their tickets to their account.
You will need to bring your phone to the concert, since they will scan the ticket's QR Code to let you in.
