sandro hiroshi, rodrigo tabata and others brazilian players teh first play now in korea, the second is a key player in santos and in goiás '05.
I heard Kawasaki Frontale went for Sandoro Hiroshi a few years ago but the deal didn't go through in the end. Urawa's Tulio is of Japanese (and Italian) descent although he moved to Japan at 15 and have never played for Brazilian professional teams.
I heard there would be alot of complications with tabata, except for the fact he doesnt want to play for japan, lol
