The ten-span sword Susanoo used to slay the Yamata no Orochi, unnamed in the "Kojiki" and the "Shoki"'s main text, is variously named in the "Shoki"'s variants as Orochi-no-Aramasa (蛇之麁正, 'Rough [and] True [Blade] of the Serpent'), Orochi-no-Karasabi-no-Tsurugi (蛇韓鋤之剣, 'Korean ("Kara") Sword of the Serpent' or 'Flashing Sword of the Serpent'), and Ame-no-Haekiri-no-Tsurugi (天蝿斫剣, 'Heavenly Fly Cutter', also Ame-no-Hahakiri 'Heavenly Serpent ("haha") Cutter'). In the "Kogo Shūi" it is dubbed Ame-no-Habakiri (天羽々斬, also Ame-no-Hahakiri). This sword is said to have been originally enshrined in in Bizen Province (modern Okayama Prefecture) before it was transferred to Isonokami Shrine in Yamato Province (modern Nara Prefecture).
