of the late is the second generation of the Yamashiro line in the 's own numbering, the smith whose dated work carries the Eitoku, Shitoku and Meitoku years. The published sources set out the line plainly: a first generation of the Enbun and Jōji years, a Ryōkai-descended Kyō smith who, they write, "is said to have studied under Sadamune of as well"; after him, in the late , "the of the next generation"; and in the early the Ōei , Saemon-no-jō and Shikibu-no-jō. The 's older Kenmu founder is set aside because no work of that date survives. Several blades in this record are appraised in exactly that position, as "a standing between the mid- first generation and the Ōei ".
He works in three manners. Two he carries forward from the first generation. The first is a refined of ko-nie, the nioiguchi tight and clear, with fine hotsure and a faint nijūba, most at home on the tantō, ko-wakizashi and ken. On a tantō dated Shitoku 2 the published sources call it an elegant straight temper that "faithfully inherits the manner of the Rai ancestors"4, and a tachi dated Meitoku 1 is read the same way. The second, and the one most often met in his corpus, is a ko-notare mixed with gunome, laid thickly in nie, with sunagashi, kinsuji and conspicuous yubashiri. The sources name the two together, as a straight temper in the Kyō tradition and a notare inheriting the manner of Sadamune.
The third manner is his own, and it arrives with the tachi, which his generation makes in number. It is a lively gunome-based midare mixing ko-notare, togariba and chōji-like heads, and its tell is named again and again: pairs of gunome "linked by a low, small notare"5, taking on a yahazu, arrow-notch, profile. A tachi dated Eitoku is described as showing "gunome set two side by side", a work that "well shows the character of the Nobukuni of this period"6. On the most animated blades muneyaki, tobiyaki and yubashiri enter, and the bōshi runs midare-komi with hakikake.
Under every temper the jigane is an itame that stands and flows, at times with masame-gokoro, with thick ji-nie and frequent chikei, the trace of the Sōshū study his line inherits. The hereditary carving goes with it. Bonji, kurikara, suken, gomabashi and the invocation of Hachiman Daibosatsu recur across the corpus, and the published sources call this "carving that could be called the family art, and skilful as one would expect"7. A small habit of the signature belongs to this generation as well: the date is cut low on the tang, well below the smith's name, which the sources describe as "seemingly a habit of the Nobukuni of this period"8.
The published sources keep him distinct on both sides. Against the first generation, the dated late-Nanbokuchōtachi and naginata are prized as reference material, since the founder's signed work survives only as tantō and ko-wakizashi. Against the Ōei Nobukuni, they note that the late-Nanbokuchō hand breaks the midare down in a more cursive manner, and they use this point to separate the generations. They are also candid that the name was shared: "there appear to have been several smiths of the same signature in the Nanbokuchō period as well"9. A Meitoku 3 tachi signed Genzaemon-no-jō Nobukuni is by a different hand from the two-character Nobukuni of the same year.
His record holds two Tokubetsu Jūyō and twenty-nine Jūyō, thirty-one blades in the Tokubetsu Jūyō and Jūyō tiers, with a prewar Jūyō Bijutsuhin and Hon'ami Kōchū origami attached to several. He has no National Treasures and no Important Cultural Properties. Of recorded whereabouts, a tantō is held in the Samurai Art Museum in Berlin, and provenance runs to the Hisamatsu Matsudaira family, the Ōta collection and, for one blade, the Imperial Family. None of his work is locked away as designated patrimony, so a signed example does pass into private hands from time to time; it comes only seldom, and a dated, carved tachi of the late-NanbokuchōNobukuni is a landmark when it does.
Historical importance
Where Nobukuni stands among comparable artisans: across all of nihontō, and within tradition, era, and period. The tiers (Foremost · Leading · Major · Notable) weigh official designations from the NBTHK and Japan's Agency for Cultural Affairs, together with historical honors of lasting repute such as the Sansaku and Meibutsu-chō.
