Yamata no Orochi
As punishment for his unruly conduct, Susanoo was then driven out of Takamagahara by the other gods. Going down to earth, he arrived at the land of Izumo, where he killed the monstrous serpent Yamata no Orochi to rescue the goddess Kushinadahime, whom he eventually married. From the serpent's carcass Susanoo found the sword Ame-no-Murakumo-no-Tsurugi (天叢雲剣, "Sword of the Gathering Clouds of Heaven"), also known as Kusanagi-no-Tsurugi (草薙剣 "Grass-Cutting Sword"), which he presented to Amaterasu as a reconciliatory gift.
