Accompanied by a certificate of registration as Juyo Token [Important Sword], no. 1352 issued by the Nihon Bijutsu Token Hozon Kyokai [Society for the Preservation of the Japanese Art Sword], dated Heisei 30 (2018).

The Uda School was founded by the smith Konyudo Kunimitsu who moved from the Uda district of Yamato Province (present-day Nara Prefecture) to the Uda district of the same name in Etchu Province (present-day Toyama Prefecture) where his school then flourished from the end of the Kamakura period (1185-1333) until the shinto era (1597-1780). Works and smiths from the end of the Kamakura to the Nanbokucho period (1336-1392) are referred to as Ko-Uda and famous masters from this group were, apart from the aforementioned Kunimitsu, Kunifusa and Kunimune. Incidentally, it is said that Kunifusa has been a student of Norishige. This blade is o-suriage mumei. It shows Yamato characteristics, but with local rural features common with works from Etchu Province.


The sayagaki attestation by Tanobe Michihiro has been translated as:


Designated as Juyo [Important Sword] at the 13th Juyo-shinsa [Examination for Important Swords]

Ko-Uda from Etchu Province

This blade is o-suriage mumei. It shows an exquisite itame that features plenty of ji-nie and much chikei and is hardened in a nie-laden suguha with a wide nioiguchi and is mixed with nie-ashi. Also, the ha is intertwined with sunagashi and kinsuji and thus we have here a masterwork of this school which does not date later than Nanbokucho and which appears to aim at its local predecessor Go Yoshihiro.

Blade length: 70 cm.

Attested by Tanzan at the beginning of spring of the Year of the Boar of this era (2019) and kao [cursive monogram]
