Korean and Japanese food are close but slightly different. Especially traditional food.
I can say both countries influenced each other.
whats the question?
um, the Japanese supposedly come from Korea. and the Koreans come from China/Mongolia. so we're all kind of connected..which leads Jews/Christians/Muslims back to Adam & Eve. the Koreans WERE oppressed by the Japanese for quite some time, so I guess it was kind of inevitable for some sort of culture meshing.
