Earth spider. In Japanese mythology, the Earth Spider, known as Tsuchigumo, is a mythical creature often depicted as a malevolent spider-like entity dwelling underground. Legends surrounding the Tsuchigumo vary, with some portraying it as a monstrous beast capable of shapeshifting to deceive and devour humans. Others depict it as a powerful yōkai (supernatural being) associated with deceit and trickery, luring unsuspecting victims into its lair. The concept of the Tsuchigumo has inspired various tales, artworks, and theatrical performances throughout Japanese history, highlighting its enduring presence in the cultural imagination.
