Look in this pic, with the U-22 team vs. Sanga. (which finished 2-2 BTW) What is that guy wearing? Is that just a practice jersey, or is it the new Japan jersey? It has a nice color scheme (though some may say it looks too much like France) and looks cool overall (though I wish it had the little bird thing w/ the JFA logo) http://www.sanspo.com/soccer/top/st200302/st2003022701.html
It looks a bit like 00--02 adidas design... which was used for a lot of teams, like Finland, China, Canada, and others... couple of examples: http://www.subside.co.uk/archive/a_shirt.asp?req=4&id=finhss01&tm=339 http://www.subside.co.uk/archive/a_shirt.asp?req=4&id=canass00&tm=377 If I remember correctly the numbering styles for these jerseys were similar to the ones on the picture too... so I'm sure that's what it is... it's probably for practice matches only.
