I found out that the Japan NT match I was talking about was against Yemen. I was too late to get an advance-release ticket from FamilyMart, and the Ticket Pia website was busy as soon as tickets went on general sale, but fortunately a member of the PUK soccer club had a spare ticket. (She had bought a ticket but was then asked to help out at the match, so she didn't need her ticket any more.) The match is part of the Asian Cup qualifying campaign. So I hope to see you at the ground on January 20th!
