Around February 3rd, a traditional Japanese event called Setsubun is held. This day marks the eve of the beginning of spring according to the old lunar calendar and was an important occasion for people in the past. Even today, the custom of bean-throwing is practiced during Setsubun to ward off evil and invite good fortune. The beans used for this ceremony are roasted soybeans, referred to as “fortune beans.“ In many households, demon masks are prepared, and family members, often children, take on the role of the demon. During bean-throwing, people throw beans around their homes, shouting, “Out with demons! In with fortune!” They throw beans outside to drive away evil spirits and inside to welcome good fortune, focusing on doorways, windows, and other key areas.
