Vinegared sushi rice is rolled up in sheets of nori (laver seaweed) with a variety of fillings, such as kanpyo (strips of seasoned gourd), shiitake mushroom, carrot, spinach, and pickles. These are arranged in such a way that the cross-section forms a pattern, such as a flower or animal, when the sushi roll is sliced. Traditionally, futomaki-zushi was prepared for auspicious occasions or ceremonial events, such as Coming of Age Day, weddings and funerals.
