Setsubun: Bean-Throwing Festival (or Bean-Throwing Ceremony) is the day before the beginning of spring in Japan… accompanied by a special ritual to cleanse away all the evil of the former year. This special ritual is called mamemaki (literally “bean throwing”).
Roasted soybeans 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! ).
