Kusanagi-no-Tsurugi (草薙の剣) is a legendary Japanese sword and one of three Imperial Regalia of Japan. It was originally called Ame-no-Murakumo-no-Tsurugi (天叢雲剣, "Heavenly Sword of Gathering Clouds"), but its name was later changed to the more popular Kusanagi-no-Tsurugi ("Grass-Cutting Sword"). In folklore, the sword represents the virtue of valor.
