Ask HN: Why can't I call myself “a Japanese”?
https://news.ycombinator.com/item?id=28793370I am a Japanese working at an American software company. My American coworkers told me that I should say "I am from Japan" instead of "I am a Japanese." I think that's really strange. You can call someone a Korean, a German, a Mexican, or even an American, but not a Japanese? What is this rule, and why does it single out Japanese?
