The custom of Mamemaki first appeared in the Muromachi period (from 1336 to 1573). It is usually performed by the toshiotoko (年男) of the household (the male who was born on the corresponding animal year on the Chinese zodiac), or else the male head of the household. Roasted soybeans (called "fortune beans" (福豆 fuku mame)) are thrown either out the door or at a member of the family wearing an Oni (demon or ogre) mask, while the people say "Demons out! Luck in!" (鬼は外! 福は内! Oni wa soto! Fuku wa uchi!) and slam the door. This is still common practice in households but many people will attend a shrine or temple's Spring festival where this is done. The beans are thought to symbolically purify the home by driving away the evil spirits that bring misfortune and bad health with them. Then, as part of bringing luck in, it is customary to eat roasted soybeans, one for each year of one's life, and in some areas, one for each year of one's life plus one more for bringing good luck for the year to come.
At Buddhist temples and Shinto shrines all over the country, there are celebrations for Setsubun. Priests and invited guests will throw roasted soy beans (some wrapped in gold or silver foil), small envelopes with money, sweets, candies and other prizes.
