From one of Orochi's tails, Susano'o took out a sword, which he called "Ame-no-Murakumo-no-Tsurugi" ("Heaven's Cloud-Gathering Sword"), later known as the "Kusanagi-no-Tsurugi". The sword was given to Amaterasu as a gift and was later given to her descendant Ninigi (the great-grandfather of Emperor Jimmu), with the "Yata-no-Kagami" (a mirror) and "magatama" (sacred jewels) as proof of his divine right to rule on Earth (the three Imperial Regalia of Japan).
