Five Japanese food staples include rice, miso soup, noodles, pickles and fish (served grilled, as sushi or in other forms). You'll often encounter all of them together as part of a set meal at a restaurant.
However, certain elements are commonly found in a typical Japanese breakfast. These include steamed rice, miso soup, grilled fish, pickles, natto (fermented soybeans), tamagoyaki (rolled omelet), nori (seaweed), and a variety of side dishes such as vegetables, tofu, or salad.
