Katana - Mumei(No Signature) - NBTHK Hozon Certificate(Sue Mihara) - Uchigatana Koshirae - Suriage Nakago - Koto Era - Iwate 16247

¥350,000 ¥400,000

This is a very affordable Koto-period katana with a certificate of authenticity, equipped with modern fittings and usable for iaido practice.

For a Koto-period piece, the blade's overall condition is generally good, though there is a chip in the blade approximately 21 cm from the hamachi, indicating actual use. The entire blade shows old polishing, but the jigane and hamon are clearly visible. The jigane features itame grain with some mokume patterns mixed in. The hamon is a narrow, straight line with a tight nioi-kuchi, characteristic of Koto period works.

Although this piece is unsigned, the Society for the Preservation of Japanese Art Swords certified it in February 2015 as a katana by Sue-Mihara and issued a Hozon certificate. Sue-Mihara refers to swords of the Mihara school, active in Bingo Province (present-day Mihara, Hiroshima Prefecture) from the mid to late Muromachi period.

They are highly regarded for their practicality and were prized as exceptional blades (wazamono) during the Sengoku period. Its defining characteristics include a hamon pattern primarily featuring sugaha, inheriting the tradition of Yamato-den, offering a distinct charm compared to Japanese swords made in neighboring Bizen. This makes them highly popular as practical weapons for samurai.

The koshirae is newly equipped with modern iaido fittings, and the tsukamaki has also been newly wrapped.

This is a work by Sue-Mihara that evokes the atmosphere of the Sengoku period, but the price has been significantly reduced due to a chip on the blade. You won't want to miss this.
