It is unrelated to the FC, you order through the site. You do have to provide your address etc. however.
I went to the site yesterday and noticed it was asking for Japanese address/phone information. That's actually what prompted my question about buying at the place.
If it was one of the Factory groups or maybe even MM, I would be all over it. I might take a pass on this one, though.
Thank you for the answer.
Thought I might give an update on this since others might have the same idea/question.
I sent an email to the AREA-Q staff and asked about buying an entry ticket from overseas since I wouldn't have a Japanese address. (I thought about this, but I didn't know if that would affect the payment, assuming credit card online.)
They suggested using the hotel address/phone number.
They also said tickets can be purchased there, but recommended buying in advance.
I leave in 16 days. Woo-hoo!!!
