Fuku mame are roasted soybeans traditionally used in the Japanese festival called Setsubun. This event marks the beginning of spring and is celebrated on February 3rd. During the festival, people throw these beans to drive away evil spirits and invite good fortune into their homes. The term "fuku mame" translates to "fortune beans." After throwing the beans, it is customary to eat the same number of beans as one's age, plus one for good luck. This practice symbolizes the hope for health and prosperity in the coming year.
