Concert Tickets via Lawson

[melodyofmysoul.livejournal.com]

Hi! I hope someone can help me with this (hopefully not so stupid) query.

I visited Johnny's net recently and went to the concert page out of curiosity, and I saw that the Ticket Availability column for Arashi's concerts was marked for both Members and Ticket Agencies. Upon checking further details on the Ticket Agencies (found here), I saw hotlines for Lawson Ticket which will exclusively open on the first day of ticket sales for a certain venue.

Given those information, I have some questions:

• Are the tickets sold through Lawson open to everyone, or does one still have to be an FC member to be able to buy these?
• If tickets are open even to non-FC members, what are the chances of obtaining tickets through this method? Is it very slim or is there still a reasonable chance of buying one?

I'm asking this since I'm planning on going to Japan in 2016 and I'm looking into watching an Arashi concert if it will coincide with my travel dates. However, I don't want to take the risk of buying a resale ticket since my budget for a concert is just enough for the original price of the ticket.

Thank you in advance to those who will be able to help!
