This authentic Japanese katana, signed by Bizen Kiyotsugu, was forged during the Muromachi period (15th-16th centuries) and belongs to the celebrated Bizen-den tradition. It features an elegant lacquered koshirae with refined raden mother-of-pearl decoration. The sword comes with its original Japanese torokusho from Mie Prefecture and a Supein Nihonto Certificate of Authenticity.
