¥300,000 ¥350,000

This sword was discovered in the old storehouse of a traditional family.

Although it is unsigned, it is a magnificent piece recognized by the Society for the Preservation of Japanese Art Swords as a work of the Uda school. Overall, the blade has been polished, but there is black rust approximately 2 mm wide on the kissaki of the sashi-omote side, along the blade for about 10 cm from the kissaki, and along the blade for about 15 cm from that point. The jigane features a mix of itame and mokume patterns, with well-defined nie. The hamon is suguha, and the niiokuchi is slightly hazy. It features a funbari and a beautiful shape reminiscent of an elegant tachi. In December 2025, at an appraisal meeting conducted by the Society for the Preservation of Japanese Art Swords, this sword was certified as an authentic Uda-school work and issued Hozon certificate, recognizing it as a piece of high value worthy of preservation for future generations.

The Uda school is said to have originated when the legendary Kunimitsu, along with his clan, moved from Uda in Yamato Province (present-day Uda City, Nara Prefecture) to Etchu (present-day Toyama Prefecture) in the late Kamakura period, forming a group of swordsmiths that flourished through the Muromachi period.

This is a truly magnificent piece, and although it comes with a Hozen certification, we have set the price very reasonably due to some rust on the sashimoto side. If you’re looking for an affordable yet superb Japanese sword, this is an absolute must-buy.
