In Japanese folklore, the moon goddess revered in Shinto is known as Tsukuyomi. She is part of the mythological family of the sun goddess Amaterasu and is associated with nighttime and the lunar cycle. Tsukuyomi’s role in mythology often emphasizes the balance between day and night, as well as the harmony of opposing forces in nature. Various stories depict her as representing calmness and introspection, contrasting Amaterasu's vibrant energy. Tsukuyomi’s symbolism reflects cultural reverence for celestial bodies and the important influence they hold over human life, particularly in relation to agriculture and the passage of time.
