1st Concert in Japan: AAA live @ Tokyo Dome in November

Hello, I'll be going to Japan for a concert for AAA, a dance vocal group. It's their first time doing a live at both Kyocera and Tokyo Domes, and I've been an overseas fan going on 11 years.

I was wondering if anybody knows the process of buying tickets to the venue. I live in the US, and it will be my first time in Japan.

Also a general idea of rules I should follow when attending? I'll be going with another friend but he's Japanese American and never been to Japan or speak Japanese. I think my nihongo is better than his...

Can you maybe give us a link regarding the event or at least the group (for those such as myself who have never heard of them)? It would probably help in tracking down the info you want.

Here I am busy googling the group, finding their website, hunting up tour dates, etc doing my best to be helpful...and you can't bother to reply?

When is this supposed top be happening? I can't find it on their official website.

It had already gotten late and I didn't realize the time! I had fallen asleep. Sorry! I didn't mean to come off as rude.
