Japanese Samurai Katana Attributed to Ujifusa NBTHK Hozon Token | Imperial Japanese Naval Tachi Koshirae | Muromachi Period An impressive Japanese katana attributed to Ujifusa and officially certified NBTHK Hozon Token, mounted in exceptional Imperial Japanese Naval Tachi koshirae with a rare sharkskin-covered saya. Dating from the late Muromachi to early Edo period, this sword originates from one of the most sought-after eras in Japanese sword collecting. Produced during the final decades of the Sengoku period, it represents the age when swords were still forged as true battlefield weapons for professional samurai. The blade is attributed to Ujifusa, son of the renowned Kanefusa and a respected representative of the Mino tradition. Swords of this school are highly regarded for their strong construction, practical design, and historical importance. With a healthy 67 cm nagasa, powerful 3 cm motohaba, and elegant overall proportions, the sword possesses the robust appearance collectors seek in authentic late Muromachi katana. A major highlight of this piece is its outstanding Imperial Japanese Naval Tachi koshirae. The mounting features a rare sharkskin covered saya, an increasingly difficult feature to find on surviving naval officer mountings. The quality and visual impact of the koshirae transform this sword into a remarkable display piece while adding significant collector appeal. The combination of a genuine samurai-period blade and prestigious Imperial Japanese Naval mounting creates a fascinating connection between Japan's feudal warrior tradition and the military history of the modern Empire. The sword is accompanied by NBTHK Hozon Token papers issued by the Nihon Bijutsu Token Hozon Kyokai, confirming the attribution to Ujifusa and recognizing the blade as worthy of preservation.
