Korean Sushi History

japanese and korean cultures??
k….i have a “friend” who is full korean (linda). i am 1/8 japanese and very proud of my background and history. she is very rude to me, and always making fun of me (rudely) because of the traditions in my family. like-sushi on christams. the other day, she told me that the japanese culture copied from korea. is this true? i tried looking it up on the computer, but none of it made sense.
Don’t worry cultures copy other cultures..so tell her that every cultures copy other ones as well.
Like the American culture copies maybe the Turkish culture.(No offense intended..or anything:D:)
It’s just a part of the culture thing.
