In Japanese folklore, creatures known as yokai and kami are often associated with mischief and fortune. Yokai can embody various forms, including animals or even inanimate objects, and are known for their playful and sometimes malevolent nature. Conversely, kami are divine spirits that can represent elements of the natural world. Some yokai, like Tanuki (raccoon-dogs), are particularly linked with good fortune, while others represent chaos and trickery in human affairs, showcasing a duality in the nature of luck and mischief.
