Cardcaptor Sakura Cafe - How to go?

I'm travelling to Tokyo while the Cardcaptor Sakura Cafe is open. I am told that there is an advance reservation system, which brings me to my questions:
-Is advance reservation necessary?
-How do I register in advance? The ticket website is confusing (I don't speak much Japanese). Do I need an account? I found some kind of registration page, but it doesn't let me put in a non-Japanese address.


Here is the cafe website:

And the ticket website:

Reservation is mandatory, and the reservation service requires registration with a Japanese address.

A reservation is necessary, they won`t let you in without it.

For the adress, just copy the adress of your Hotel or any other place, i did that and it worked and as far as i know, other people also used their Hotel adress.

Thanks Jacki. I just contacted my hotel and they said that would be okay.

I didn't know this existed! Love Card Captor Sakura :D Does anyone know will it be easy to go if we don't speak/read Japanese?

So did anyone went?
Need a review n on how its like (foreigner experience) n is it worth the hassle
