Setsubun is a Japanese custom.

Today (February 3rd) is Setsubun. It's a Japanese custom to bring luck.
Many Japanese are going to perform a special ritual called Mamemaki.
Mamemaki involves throwing soy beans in their rooms and at the entrance while saying "oni wa soto, fuku wa uchi."
This phrase means "evil out, luck in." 
After they have thrown the beans, they eat the beans, one for each year of a person's life.
For example, a 20 year old man would eat 20 beans.

I wish I were in Japan right now so I could see this. Good writing.
