Good question. My answer to the question is "No, I don't know any Japanese person who eat every day or for every meal." Sushi is still considered as a superb meal at nice restaurants. Generally speaking, we Japanese have a kind of set consisted of rice and miso soup and main dish(like, grilled fish, raw fish, chicken ) for lunch or dinner ordinary. Rice and miso soup are staple food for us(probably rice and miso soup roles are quite close to pasta for Italian).

Recently, sushi is getting much familiar among people, because we can have cheap sushi at grocery store or even convenience store, also number of conveyor-belt sushi restaurant is significantly increasing, they serve sushi at quite cheap price(1 plate = less than 1$).
