Oni are mythical creatures from Japanese folklore, often depicted as large, fearsome demons with horns, wild hair, and sharp claws. They are typically portrayed in bright colors, such as red or blue, and are known for their strength and ferocity. Oni are commonly associated with mischief and evil, but they can also serve as protectors in some stories. In traditional tales, Oni are often seen carrying large clubs and are known to inhabit remote mountains or caves. They are frequently featured in festivals, such as the Setsubun celebration, where people throw beans to drive away evil spirits, including Oni, and invite good fortune into their homes.
