Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
We proudly present this unsigned katana, which features a sayagaki by Sato Kanzan, a leading authority on Japanese sword appraisal, and comes with a certificate of authenticity from the Society for the Preservation of Japanese Art Swords. The blade is in excellent condition, has been polished, and is sound throughout. The jigane features a blend of itame and mokume patterns that is truly awe-inspiring. The hamon exhibits a mix of notare and gunome patterns, with a moist, lustrous nioikuchi. The active hataraki—such as yo, ashi, and tama—are vibrant, making this a sword that never ceases to captivate the viewer. The boshi has a pronounced return that extends to the center of the blade, giving it a hitatsura-style appearance. Although unsigned, in April 1975, the Society for the Preservation of Japanese Art Swords certified this work as a katana by the second-generation Nobutaka and, recognizing its exceptional value, issued a “Tokubetsu Kicho” certificate of authenticity. Speaking of the second-generation Nobutaka, he was a master swordsmith representing the Shinto period who was active in Owari Province (present-day Aichi Prefecture). He produced excellent swords from the early to mid-Edo period, and his collaborative works with the third-generation Nobutaka are also known for their exceptional quality. He succeeded his father, the first-generation Nobutaka, and received the title “Hoki-no-kami” in 1633. He retired and became a Buddhist monk (taking the name Kanyu) in 1662, and continued to forge swords energetically until his death in 1689 at the age of 87. His swords are renowned as practical, battle-ready masterpieces cherished by samurai such as those of the Owari Yagyu Shinkage-ryu school, and are highly regarded by connoisseurs. The sword is equipped with a high-quality shirasaya featuring a sayagaki by Sato Kanzan, a leading authority on Japanese sword appraisal. The sayagaki states that this work was crafted by the second-generation Nobutaka, indicating that

The San'ami line takes its root in Mino Province, where its head smith Kanenori (兼則) worked as one of the so-called Seki Seven Schools. The setsumei place Kanenori from the close of the Nanbokuchō period into the Ōei era of the early Muromachi, alongside Kanemoto and Kanesada among the representative hands of Sue-Seki, and the earliest extant signed tachi of his is appraised as no later than Ōei. A second early smith, Kanekuni (兼国), is recorded as belonging to the San'ami lineage and is judged to predate the Sue-Seki group proper; the remote ancestry given for him runs variously to a disciple of Naoe Kanetomo, to Yamato Kanekuni, or to Kanenori, though the setsumei note that nothing survives to confirm so distant a descent. From this Mino stock came Hōki no Kami Fujiwara Nobutaka (信高), born at Kami-Ōchi in Mino in 1563 and said to descend from San'ami Kanekuni. After receiving the title Hōki no Kami in Tenshō 9 (1581) he moved to Kiyosu in Owari and, serving Tokugawa Yoshinao, later settled at Nagoya, carrying the line into the early Shintō era through a second generation who took the tonsure in Kanbun 2 (1662). Across the corpus the jigane is itame, often closely forged and tending to nagare-hada or flowing grain along the edge, with ji-nie and a frequent standing of the grain (hada-dachi); a faint whitish cast (shirake) marks the older Mino work of Kanenori and Kanekuni. The temper rests on suguha as a base. In the early hands it is a tight, clear (saete) suguha in nioi-deki, sometimes mixed with small gunome, angular elements and pointed ha, carrying ashi, hotsure and scattered tobiyaki.
The Nobutaka works open this out: a broad suguha shifting to shallow notare, ko-notare with a gunome-flavored edge, deep nioi with nie unevenly applied and partly coarse, nie-kuzure at the yakigashira, kuichigai-ba, kinsuji, sunagashi, yubashiri and tobiyaki that climb into the shinogi-ji until the upper half reads as hitatsura. The bōshi runs to sugu with ko-maru, at times midare-komi, pointed, or hakikake, and the early swords keep a slender, high-sori tachi shape while Nobutaka's carry the wide-bodied, ō-kissaki form of the Momoyama transition. The hand is recognized in this pairing of a flowing Mino itame with a suguha core that, in the descendants, breaks toward bold hitatsura. For kantei, the setsumei fix several anchors. In Kanenori's signature the scooped chisel at the fourth stroke of the character kane (兼) is read as a trait of late Nanbokuchō through Ōei work, matched in dated Kaneyoshi mei; the clear suguha of Kanekuni is likened to a Zenjō Kaneyoshi masterpiece. The jizō-flavored bōshi and the nagare-mixed itame in Nobutaka are named as the surviving stamp of the Mino root beneath his Owari manner, and one of his katana is recorded as an Inabae-utsushi. Provenance runs through the corpus: a Kanekuni bears kinzōgan recording it as the sashiryō of Ōkubo Genban-no-jō Tadanari, lord of Odawara in Sagami, worn at the age of ninety-three; Kanenori's tachi descended in the Yamanouchi family. Among the Owari yari makers beginning with Masatsune, Nobutaka's yari of extraordinary length is held in particular regard, and the second-generation Nobutaka is judged no less skilled than his father, with the finest extant Nobutaka works counted to his hand.
