Hello! I am wondering who here has experience getting a-nation tickets? My friends and I are off to Nagoya in August and hopefully we can catch an a-nation concert. I just do not where in Japan there is to buy tickets? My friend is from japan and she has friends/family/connections there so contact is not a problem. However, her friends do not know really where to get tickets

. Besides yahoo actions japan(because we need 3 tickets for all of us), is there like a store in japan, or an online store even a phone number we can access for tickets? Access and communication is not a problem since my friend can speak the japanese language, has a japanese address and credit card!
I hope anyone here can help, especially the ones living in Japan! Thank you
(Anyone has any idea around what time concert listing are up and when tickets are going on sale?)
