In Japanese folklore, the Baku is a mysterious dream-eating creature that has captivated imaginations for centuries. This mythological being, often depicted with the body of a bear, elephant’s trunk, tiger’s paws, and ox’s tail, serves as a protective spirit against nightmares and evil spirits.
Legend tells that when the gods created all living creatures, they used leftover pieces to form the Baku. Despite its chimeric appearance, this supernatural entity plays a benevolent role in Japanese mythology, consuming bad dreams and protecting sleepers from harm. People often invoke Baku’s name before bedtime or keep its image near their beds to ensure peaceful rest.
Origins of the Baku in Japanese Folklore
The Baku emerged from Chinese mythology as the ‘Mo’ (貘) before evolving into a distinct Japanese mythological creature during the Muromachi period. This transformation significantly shifted the creature’s symbolism from a general protective spirit to a specialized dream-eating entity.
Ancient Tales and Historical Records
Japanese folklore documents Baku’s creation from unused spare parts after the gods completed their work on other animals. The earliest written records of Baku in Japan date to the 14th-15th centuries, coinciding with increased cultural exchange between China and Japan. The creature’s initial role in Chinese mythology focused on protecting against illness and malevolent forces, while Japanese tales emphasized its nightmare-devouring abilities.

The creature’s depiction evolved uniquely in each area while maintaining its core identity as a dream-eating spirit. These regional adaptations contributed to the rich tapestry of Baku mythology in Japanese culture.
