NihontoWatchNihontoWatchSince ancient times, the first generation Nobukuni has been called a pupil of Soshu Sadamune, with his era attributed to Kenmu, but among extant works there are none at all with Kenmu or nearby dates, nor are there works found that can be appraised as going back that far; furthermore, because the style of the oldest extant Nobukuni works with Enbun and Joji dates connects directly to Sadamune, the common theory today is to regard the Enbun and Joji generation as the first. According to records, he is written as the son or grandson of Ryo Hisanobu (son of Ryokai), and the fact that suguha, which is the tradition of the Rai school, is seen in works dated Enbun 3 and Koan 1, and that the kitae flows regardless of whether the hamon is suguha or midareba, makes the attribution convincing. At the end of the Nanbokucho period, there were successive generations of Nobukuni, and further, among the Nobukuni school after entering the Oei era, the two smiths Shikibu-no-jo Nobukuni and Saemon-no-jo Nobukuni are famous as representative smiths, and there are other swordsmiths who sign with the niji-mei Nobukuni; since they all carve Oei dates, they are referred to as "Oei Nobukuni." It is not clear how many people used the same mei, but as expected of a prestigious lineage of Kyo smiths, excellent works are seen among the pieces by swordsmiths who call themselves Nobukuni. The style of the first generation Nobukuni mainly consisted of two types: suguha showing the tradition of Kyo-mono and notare-ba inheriting the Sadamune style, but from the successive generations of Nobukuni at the end of the Nanbokucho period through to "Oei Nobukuni," a style of gunome-style midareba was newly added in addition to the aforementioned styles. This tanto is appraised as the aforementioned successive generation Nobukuni, and it is a good tanto that clearly shows the characteristics of the Nobukuni school, with a refined jigane of ko-itame mixed with moku, and a fired notare-style gunome. Please by all means submit it for Tokubetsu Hozon Token shinsa.

Few Kyoto houses bridged two traditions as deliberately as Nobukuni (信国), the Yamashiro-den lineage whose work runs from the Nanbokucho period through Muromachi and on, in a western branch, into the shinto age. The first generation, the smith the NBTHK counts as shodai, is the master of the Enbun, Koan and Joji years; the older registers placed a founding Nobukuni back in the Kenmu era, but the published sources set that legend aside, since no work survives so early and the style of the oldest dated blades connects directly with that of Sadamune. Two inheritances meet in him. By blood he belongs to the Ryokai line, recorded as son or grandson of Ryo Hisanobu and therefore of Rai descent; by training he is said to have studied under Soshu Sadamune, counted among the Sadamune Santetsu, the three brilliant pupils. The name then passed on: a change-of-generation Nobukuni with Eitoku, Shitoku and Meitoku dates stands at the close of Nanbokucho, and in early Muromachi come the so-called Oei Nobukuni, Saemon-no-jo and Shikibu-no-jo, conventionally the third generation. The published commentary keeps these hands apart and notes that several smiths of the same signature appear within the Nanbokucho period alone. Through Muromachi the line moved to Buzen and then Chikuzen, where it served the Kuroda house of Fukuoka as retained smiths and flourished as the Chikuzen Nobukuni group of Yoshisada, Yoshimasa, Yoshitsugu, Yoshikane and Shigekane. A single steel underlies the whole school. The jigane is an itame mixed with mokume that flows toward the ha and stands into masame, with thick ji-nie and chikei entering frequently; on the finer-forged pieces a streak-like nie-utsuri rises, and that masame-tinged surface is read as the visible token of the Ryokai pedigree.
Over it the temper divides into the manners the sources name together: a suguha expressing the Kyoto tradition, refined in ko-nie with fine hotsure and a niju-ba tendency, carried on tanto and ko-wakizashi; and a ko-notare mixed with gunome inheriting the Sadamune style, laid thick in nie, with kinsuji, sunagashi, hotsure and conspicuous yubashiri, on the most flamboyant pieces stringing into a two-tiered ha. From the late Nanbokucho succession into the Oei generation a third range enters, a gunome-led midare whose tell is paired gunome linked across the valleys by a low ko-notare into a yahazu, arrow-notch, profile, with muneyaki, tobiyaki and niju-ba on the liveliest blades. Above all stands the carving the sources call the house art, the horimono of bonji, kurikara, suken, gomabashi, sanko-ken and the invocation of Hachiman Daibosatsu, often layered one over another in kasanebori; few smiths of the age are so consistently identified by what they carved. The Chikuzen branch carried the masame-leaning itame forward and added a choji-midare with midare-utsuri, Yoshikane reaching toward Soshu-den with deep nioi and thick nie, Shigekane ranked highest in skill within his group and noted as a copyist of meibutsu who emulated Fudo Kuniyuki at the Hama Palace. To kantei Nobukuni is to read the Kyoto traces that part him from Sadamune: the nie-utsuri, the niju-ba, and the hada that drifts into masame along the ha. Within the long succession the shodai remains the touchstone, his dated work the standard against which unsigned blades and generation questions are resolved, the reversed left-form kuni marking the Oei Saemon-no-jo, the yahazu the daigawari hand. The best members rank Jo-jo saku under Fujishiro, and the carving reputation is the constant thread, distinguishing these blades from the plainer utilitarian grooving of contemporary Bizen. Provenance runs through the great houses: the Kuroda wakizashi once carried by Kuroda Nagamasa, a Hongan-ji meibutsu held to have been cherished by Rennyo Shonin, the signed Arao Nobukuni descended in the Asano of Geishu, pieces in the Sanada, Tosa Yamauchi and Tamura families, and a tachi bestowed on the Owari Tokugawa. Examples rest today in the Tokugawa Art Museum, the Kyoto National Museum, shrines such as Atsuta and Ise, and long-held private collections, with the Chikuzen smiths' shogunal-command pieces preserving the historical episodes that produced them.

Yamashiro in the Nanbokuchō period
The divided-courts war impoverished the court society that had sustained Kyōto’s most refined work. With the last Rai masters the classic line effectively closed, while Hasebe and Nobukuni carried the new Sōshū manner into the capital.
Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
