The very first time I came to Japan, I knew virtually no Japanese, and I don't remember seeing much English. Ditto for the 2nd time. BTW that was 9 years ago. Now I speak and read Japanese a lot better, and I notice the English much more.
I wonder if the actual amount of English has increased, or if you just notice it more a) the longer you stay or b) the more Japanese you know.
Any thoughts?
