In Japanese folklore, a yōkai is a spirit or supernatural creature often representing various aspects of the natural and spiritual worlds. Yōkai can embody both benevolent and malevolent traits, serving as protectors or tricksters within folklore. Their stories often reflect the complexities of human experience, blending humor and horror, and offering lessons about morality and the unknown. Furthermore, yōkai remind individuals of the cultural significance of nature and the unseen forces that shape their lives, reinforcing connections between the visible and spiritual realms.
