Kusanagi

Kusanagi-no-Tsurugi (^?) is a legendary Japanese sword and one of three Imperial Regalia of Japan. It was originally called Ame-no-Murakumo-no-Tsurugi (^?, "Sword of the Gathering Clouds of Heaven"), 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.

The history of the Kusanagi-no-Tsurugi extends into legend. According to Kojiki, the god Susanoo encountered a grieving family of kunitsukami ("gods of the land") headed by Ashinazuchi (足名椎^?) in Izumo Province. When Susanoo inquired of Ashinazuchi, he told him that his family was being ravaged by the fearsome Yamata-no-Orochi, an eight-headed serpent of Koshi, who had consumed seven of the family's eight daughters and that the creature was coming for his final daughter, Kushinada-hime (奇稲田姫^?). Susanoo investigated the creature, and after an abortive encounter he returned with a plan to defeat it. In return, he asked for Kushinada-hime's hand in marriage, which was agreed. Transforming her temporarily into a comb (one interpreter reads this section as "using a comb he turns into [masquerades as] Kushinada-hime") to have her company during battle, he detailed his plan into steps.
