豆まき – Bean Throwing
People in ancient Japan believed that they got sick due to evil spirits when the season changed. The bean-throwing ceremony or mamemaki (豆まき) was first held at local shrines and soon after people started doing it in their homes. Usually for a mamemaki an adult man puts on a demon mask and shows up at a house. Family members chase him and throw soy beans at him while they yell “out with the demon and in with good fortune! (鬼は外、福は内)”.
