The Kusanagi-no-Tsurugi is a legendary sword from Japanese mythology. Folklore suggests that it was created and handed down by Amaterasu, the sun goddess of Japan. Amaterasu is also considered to be the mythical ancestor of the Japanese Imperial family, and played a crucial role in the formation of Japan. This straight, double-edged sword is known for its mystical abilities. The legend tells that Susanoo, the storm god, wielded it to defeat an eight-headed serpent. After this victorious battle, the sword granted Susanoo the ability to manipulate the wind and repel fire. Currently, it's believed that the sword is safely stored in the Atsuna Shrine in Japan. However, it's never been displayed to the public.
