Interesting. So my book about being Japanese American in Japan talks about the different experiences of those of us from Hawaiʻi vs. Continental US. Not only the way we identify outside of Japan but the way we identify and our different experiences in Japan. Apparently many Japanese people from Hawaii are widely accepted in Japan by Japanese people. While Japanese Americans are more excluded in Japan by Japanese people. Even when both (Continental US and Hawaii) are both 100% Japanese.
And I know recently I got into an argument with someone (not Japanese) who called me American and I said I was from Hawaii and they tried to tell me that I was American. This book helped solidify that here in Hawaii, many of us also differentiate from those in the Continental US when it comes to our views towards our identity. Not because we hate the US but the cultures and the likes are different.
