Setsubun means “division of the seasons” in the literal sense. In ancient times the beginning of each season was called Setsubun. On the Setsubun day, various rituals were conducted to drive away devil’s sprits. Nowadays, however, Setsubun only refers to "Risshun" (beginning of spring) because the day is the most important than the other Setsubun day since the day is a new year’s day in lunar calendar.It is said that both of beans and rice have spiritual power in it, and to throw these things is a good way to drive demons from our own and our house. People used to throw rice in ancient time, but people started to throw beans instead of rice since Chinese folkway was introduced. Since then, people throw beans to drive demons on Setsubun day.
