I've had a couple of instances in Tokyo where I would say something in Japanese and I'd get replied to in English for a brief conversation, because they didn't want to speak Japanese to me. A couple of instances were Japanese people, and the biggest problem I have is an Indian fellow who works at my local McDonalds. We always have these weird exchanges because he can speak Japanese (working with Japanese customers all day) but whenever I go up to him he immediately tries his hand at English, which isn't so bad. I just start in Japanese, because I don't want to be treated differently, but he refuses to speak Japanese to me so we have really awkward Japanese-English conversations.
But this really isn't a regular thing, and most Japanese people will be really glad that you're trying to learn and speak their language.
