Also, there is a traditional custom that people eat as many beans as their ages to pray for their future well-being. If you are wondering why you see a stack of soybean bags sold at supermarkets only around this season, this will help answer your question.
Actually, the number of people who do the bean-throwing is getting fewer as it is bothersome having to clean up the cracked beans spread in rooms afterwards. Instead, another custom is getting popular that is to eat long Norimaki (Sushi rolls) on Setsudun day, this new custom must have been created for the market expansion of Norimaki.
To experience Mamemaki, it is recommended to visit large temples or shrines on the 3 of February as the Mamemaki festival is held. At the festival, you are not to throw beans, but Sumo wrestler, Kabuki players or those celebrities participate in and they throw beans with tiny gifts toward visitors, which make a chaotic fever among people trying to get the gifts.
