beans for the bean-scattering ceremony
Refers specifically to the roasted soybeans thrown during Setsubun (February 3rd) to drive away evil spirits and invite good fortune.
On Setsubun, we scatter the beans of the bean-scattering ceremony to drive away the demons.
Literally 'year beans' (年 + の + 豆). The name reflects their role in the annual Setsubun ritual to mark the transition from winter to spring.
