I saw the Japan v.s. Brazil World Cup match (June 22, 2006) with a group of 8 Japanese people in some coffee shop. Japan owned Brazil for almost all of the original time of the first half.
I remember how crazy my Japanese friends went when Tamada scored Japan's only goal. Of course, their happiness did not last long when Ronaldo scored an equalizer 10 or so minutes later... it was a great match and a valuable experience for me being with Japanese spectators.
Japan's GK Kawaguchi was really great in that match. He was the best player in that match, IMO.
