February 3rd, one day before Risshun, the first day of spring on the lunar calendar, is called Setsubun in Japan. Traditionally, people throw roasted soy beans called fuku mame (fortune beans) at home shouting, "oni wa so to" (get out demons) and "fu ku wa uchi" (come in happiness.) It is believed that people can be healthy and happy if they pick up and eat a number of fuku mame equal to their age.
