www.fdjp.com is how I usually get them. Otherforeign BoA fans that I have met at Japanese concerts have also used them. Very reliable however these are resale tickets so they are much more expensive than listed prices but frequently they can get extremely good seats for extremely high prices. They take Paypal and work in English. The website explains how it works. The tickets may not be available until just days before the concert but they will deliver them to your hotel room. God willing,I am planning to go as well (I already contacted them).
How's the progress Robert? Did you get the ticket yet? Where are you from?
ppl on reddit have found bridge and japanconcerttickets to be reliable.
i emailed govogagin and the guy said tikets will only go on sale on 14nov. anyone knows where this 14nov came from? I havent seen it anywhere
Are you buying ticket from http://www.japanconcerttickets.com/? Because I'm also planning to go to Japan this Dec to see BoA's concert. But it's very difficult for foreigners fans to get the ticket. They only sell ticket on Yahoo Japan and there's no option for International fans to buy it from there. I don't understand Japanese.
