In the basement of Tokyo Station is a large shopping mall. Yaesu Hatsufuji is a popular izakaya (Japanese pub) that also serves traditional Japanese breakfasts starting at 7 a.m. The shop fills up quickly as area office workers come for a healthful breakfast. The breakfast includes rice, miso soup, pickles, seaweed and a main dish of grilled salmon, meat and tofu, or a bowl of natto (fermented soybeans).
