Eho-maki (fortune rolls) are futo-maki (thick sushi rolls) eaten on the night of Setsubun. To be related with the Seven Deities of Good Fortune called Shichifukujin, seven fillings are traditionally rolled in a sushi roll. For example, simmered shiitake mushrooms and kanpyo (dried gourd), cucumber, rolled omelet (tamagoyaki), eels, sakura denbu (sweet fish powder), and seasoned koyadofu (freeze-dried tofu) are used. These ingredients represent good health, happiness, and prosperity, and rolling the fillings means good fortune.
Usually, sushi rolls are sliced into bite-sized pieces. But fortune rolls aren't sliced since slicing indicates cutting good fortune. When eating fortune rolls, people face toward the good fortune direction of the year and make wishes.
