Koreans and angry Koreanish-Americans don't like Ichiro, and not simply because he's Japanese and really good. There are quotations attributed to him where he says that Koreans smell like garlic, though the original source is never given. He was also quoted as saying he'd like to beat South Korea so badly in the 2006 WBC they'd won't want to play Japan for 30 years, although that may be a misquotation as other variations also exist.
Regarding Korea yesterday, who Japan may end up playing once or twice more, he said:
“This is a difficult game. There’s a destiny,” said Japan’s leadoff hitter, Ichiro Suzuki.
“It’s like a girl you said goodbye to and then you bump into the same girl again on the street so many times, because there’s a destiny to meet again.
Ichiro is known for his colorful comments, so it's not like he reserves them for Korea. You can find pages devoted to great Ichiro quotes, but I won't link to them because they don't cite any of their sources. I will, though, use the World Baseball Classic as an excuse to post what I consider the best Ichiro quotation, on Pittsburgh's rival Cleveland:
"To tell the truth, I'm not excited to go to Cleveland, but we have to. If I ever saw myself saying I'm excited going to Cleveland, I'd punch myself in the face, because I'm lying."
It was about having to play a make-up game there, but it's still funny.
