Kusanagi - Legends

Legends

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 Kushinada-hime") to have her company during battle, he detailed his plan into steps.

He instructed the preparation of eight vats of sake (rice wine) to be put on individual platforms positioned behind a fence with eight gates. The monster took the bait and put one of its heads through each gate. With this distraction, Susanoo attacked and slew the beast (with his sword Worochi no Ara-masa). He chopped off each head and then proceeded to the tails. In the fourth tail, he discovered a great sword inside the body of the serpent which he called Ame-no-Murakumo-no-Tsurugi, which he presented to the goddess Amaterasu to settle an old grievance.

Generations later, in the reign of the Twelfth Emperor, Keikō, Ame-no-Murakumo-no-Tsurugi was given to the great warrior, Yamato Takeru as part of a pair of gifts given by his aunt, Yamato-hime the Shrine Maiden of Ise Shrine, to protect her nephew in times of peril.

These gifts came in handy when Yamato Takeru was lured onto an open grassland during a hunting expedition by a treacherous warlord. The lord had fiery arrows fired to ignite the grass and trap Yamato Takeru in the field so that he would burn to death. He also killed the warrior's horse to prevent his escape. Desperately, Yamato Takeru used the Ame-no-Murakumo-no-Tsurugi to cut back the grass and remove fuel from the fire, but in doing so, he discovered that the sword enabled him to control the wind and cause it to move in the direction of his swing. Taking advantage of this magic, Yamato Takeru used his other gift, fire strikers, to enlarge the fire in the direction of the lord and his men, and he used the winds controlled by the sword to sweep the blaze toward them. In triumph, Yamato Takeru renamed the sword Kusanagi-no-Tsurugi (lit. "Grasscutter Sword") to commemorate his narrow escape and victory. Eventually, Yamato Takeru married and later fell in battle with a monster, after ignoring his wife's advice to take the sword with him.
