This is a silly complaint in this particular matter.
1. The guy is paid millions to play baseball. His employer doesn't care if he can speak English.
2. I don't know but he probably lives in Japan during the off season. If so, he likely considers Japan to be his home, not America, and he wants to be Japanese so he feels little reason to learn English.
3. He probably can speak a bit of English and can probably understand the reporters questions. Most Japanese learn a decent amount of English in jr. high and high school, even if they attended one of the schools that focus on baseball, which I think Ichiro did. However, Japanese culture is such that people are reluctant to put themselves in a position where they might make mistakes. This is certainly true when speaking English. Maybe he doesn't want to speak it in public if he's not sure that he won't make any glaring mistakes.
4. I don't know what American companies hire him for promotion here but I'm sure that he's a hero in Japan and makes a ton of money representing Japanese companies. Perhaps he's been advised that he will remain more marketable if he doesn't do interviews in English.
Nobby? Any thoughts?
Anyway, I think it's best for most people who live here to learn the language but this is probably a reasonable exception.
And how about that hit! This was the first inside the park that I've seen. Too bad it was a stand up and not a close, exciting play at the plate.
