Katana - Mumei(No Signature) - NBTHK Hozon Certificate(Ujiyoshi) - Uchigatana Koshirae - Ubu Nakago - Koto Era - Akita 1427

¥750,000 ¥800,000

We proudly present an unsigned sword in excellent condition, accompanied by a Hozon certificate from the Society for the Preservation of Japanese Art Swords(NBTHK). 

The blade's preservation is outstanding, remarkably clean and sound for a work from the Koto period, free from forging flaws, rust, or chips. The jigane features a well-kneaded itame grain, while the hamon, primarily notare, incorporates occasional loose midare, resulting in a moist, niōi-kuchi finish. Furthermore, the hamon is reflected in the hiraji in a tobi-yaki style, creating a dynamic and lively work.

Although this piece is unsigned, in March 1991, the NBTHK certified it as the work of Ujiyoshi and issued a Hozon certificate, recognizing its high value for preservation for future generations. Ujiyoshi was a renowned master swordsmith active in Awa Province (present-day Tokushima Prefecture) from the mid to late Muromachi period.

During the Sengoku period of the Muromachi era, Awa Province was a thriving center for swordsmithing, with over sixty swordsmiths active along the banks of the Kaifu River. It was so prominent that the lord of Kaifu Castle himself forged swords to meet the practical needs of his naval forces.

The koshirae features an elegant tsuba paired with a later-added fuchigashira. This attractive koshirae further enhances the charm of this katana forged during the Sengoku period. With its practical aspects, suitable for both drawing and iaido practice, we encourage you to add this piece to your collection.
