Sorry for your bad experiences. I was born there, but I must have missed whatever did you wrong. Sumimasen.
As for the Japanese and the Northeast US, seems like apples and oranges to me, or apples and apples or oranges and oranges. Both places are heavily involved with seafood, and respect it's proper preparation.
Your link was interesting - out of 34 different kinds of sushi, one used himono. As I said, I've never seen it myself.
“I was born there”
Oh? What hospital were you born in? How long did you live there?
“but I must have missed whatever did you wrong.”

“As I said, I’ve never seen it myself.”
Yes, I’ve often remarked that being present in a place is not the same thing as learning that place.
