Just an update for those still trying to get a ~Unchained~ ticket from overseas:
Based on announcement from BoA's official Japanese site, the public lottery is now open through Yahoo Tickets:
Because this is Yahoo Tickets (public) and not Yahoo Tickets Premium, you do NOT need to pre-register a local Japan credit card or bank account for processing the premium membership fee.
All you need is to sign up for a free Yahoo Japan account with a valid email address and a fake local Japanese address. The price is the original 9800 yen plus about 1000 yen of service charges. If you win the lottery (announced Jan 20), you have until Jan 25 to pay for it (I'm guessing through credit cards, but not sure if they accept foreign cards). Successful payment will secure the ticket. Yahoo will email you a ticket reference number about 3 weeks before the concert date, in which you must walk into a Family Mart (convenience store) with the reference number to pick up the physical ticket that has your seat number.
Be warned, because this lottery round is already after Fan Club and after Yahoo Premium, the seats may not be as good.
