These are the matches I went to (except the Japan one). In the course of the tournament, I visited Saitama twice, Sapporo, Niigata twice, and Osaka. I turned down a couple of chances to go to other games, and couldn't afford to go to England-Brazil.
I only hope I have the same luck getting tickets for Germany...
Ireland 1 Cameroon 1 (Niigata)
England 1 Argentina 0 (Sapporo)
Japan 1 Russia 0 (Riki's Bar, Urawa)
