Susanoo (also spelled Susano-o or Susanowo) is a powerful deity in Japanese Shinto mythology, known as the storm god and brother of the sun goddess Amaterasu and the moon god Tsukuyomi. He is associated with sea storms, chaos, purification, and heroic action.
Born from the nose of the creator god Izanagi, Susanoo is part of the central divine trio. He is known for his volatile nature, which led to conflicts with Amaterasu, causing disorder in the heavens. After being banished from heaven, Susanoo descended to the earthly realm of Izumo.
One of his most famous myths involves slaying the eight-headed serpent Yamata-no-Orochi. After defeating the serpent, he discovered the legendary sword Kusanagi-no-Tsurugi (originally Ame-no-Murakumo-no-Tsurugi) in its tail. This sword later became one of the Three Imperial Regalia of Japan.
Despite his chaotic traits, Susanoo is also revered as a cultural hero, protector, and bringer of fertility. He represents the transformative power of nature, where destruction clears the way for renewal. In spiritual practice, he embodies purification and overcoming negativity.
Shrines dedicated to Susanoo include Susa Shrine and Yasaka Shrine. He is still honored in rituals involving protection, exorcism, and safe travel.
