On February 3rd in homes throughout Japan, family members will walk through the rooms of their home throwing beans (mamemaki) in a purifying ritual. While tossing the beans family members will shout oni wa soto, fuku wa uchi (demons out, good luck in) as if to bring about fortuitous luck in the upcoming year. It is common for one person to
play the role of the oni (demon) in this ritual. Often the father of the household is relegated to this job. During this period of seasonal change, like others, was believed to have been a time when evil spirits and monsters gathered, and caused plagues and other disasters. Family members will also eat an amount of beans in accordance with their individual ages sometimes adding one. The addition of one bean may be a symbolic assurance of living another year or may reflect kazoedoshi (a traditional method of counting age in which the one year is counted for time in the womb). Beans are eaten so as to ward off evil and increase resistance to illness.
