NihontoWatchSummary This blade was signed by Hoki no Kami Fujiwara Nobutaka (伯耆守藤原信高). The swordsmith’s name “Nobutaka” lasted 6th generation during the Edo period. Hoki no Kami was an honorable title given to this swordsmith, and the 1st-5th generation received this title. It is said that Nobutaka was a descendant of Kanekuni, who belonged to Mino koku San-Ami school. We believe the attribution was given to the first-gen Nobutaka, who was especially active during 1596-1615 (Late Azuchi Momoyama- early Edo period). The first-gen Nobutaka was originally from Mino province, which is famous for Japanese sword tradition, MINO-DEN. The first-gen moved to Owari castle at the beginning of the Keicho era(the late 1590s). And he relocated to Nagoya after Nagoya castle was built. There were many swordsmiths from Mino province who moved to Owari province. They are called Owari Seki. The most famous swordsmiths categorized as Owari Seki are the first-gen Hoki no Kami Nobutaka, Hida no Kami Ujifusa, and Sagami no Kami Masatsune. All the highly refined sword-forging techniques the first-gen Nobutaka had passed down to the second-gen. As Owari province(today’s Aichi prefecture) was active in martial arts during the early Edo period, there was much demand among high-class Samurai to order swords forged by the second-gen Nobutaka. He often worked with his son(the third-gen Nobutaka), and there is some remaining work where both signatures are found. This blade is appraised as a Tokubetsu Hozon Token (特別保存刀剣) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). *Please keep in mind that there are a couple of Kitae Kizu on this blade. Fuchi-Kashira We believe the theme of this Fuchi-Kashira is Sasa (笹:bamboo glass). Bamboos grow neatly towards the sky, and it is vital so that this motif represents nobility and strength. Besides, the bamboo breaks straight, but its content is hollow; people thought it showed innocence. According to a foreign legend, the Houhou (鳳凰, Fenghuang) eats bamboo fruits; therefore, bamboo has been considered a sacred plant. Also, as it keeps its green color even in cold winter, people thought the bamboo pattern represented eternity and longevity. Tsuka and Menuki We assume the motif of this Menuki is harness(馬具, Bagu), which was traditionally used during special occasions such as weddings or grand ceremonial processions (seigi 盛儀). These occasions were marked by elaborate and festive rituals, and the harness would be used to adorn the horses, symbolizing prestige, celebration, and the importance of the event. The decorative gear was an essential part of these ceremonies, enhancing their grandeur and significance. Tsuba and Habaki This Tsuba has a family crest called the Aoi-Domoe / Mitsuba-Aoi-no Mon (葵巴/三つ葉葵の紋). This family crest consists of three hollyhock leaves arranged in a circle with their heads together. And the petiole is curved to the left side. This crest is known as the family crest of Tokugawa Shogunate family led by Tokugawa Ieyasu, a famous military commander of the Warring States period. This plant pattern has also been used for the crest of the Kamo shrine in Kyoto prefecture. As mentioned above, the famous Shogunate family, the Tokugawa family, had their family crest with three leaves of Aoi due to the relationship with the Kamo shrine. As its leaves have a habit of always facing the sun, and the word “Aoi” is taken as “Aogu (仰ぐ, looking up)” for the sun, people thought the Aoi pattern would bring good fortune. Saya The surface of this Saya is decorated with the Nashiji Nuri (梨子地塗/梨地塗) technique, which is a kind of Makie (蒔絵) method. This surface treatment method creates a rough texture by creating fine unevenness on the surface of the metal. They also come in varying degrees of gloss, including glossy, semi-gloss, and matte. According to a theory, it was invented in the Kamakura (鎌倉) period (1185-1333), and in the Edo period, various techniques were devised to color artifacts. Authentication Paper They authenticated the blade on March 2nd in the 4th year of Reiwa (2022). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society.

The first-generation Hoki no Kami Fujiwara Nobutaka was born in Eiroku 6 (1563) at Kami-Aruchi in Mino Province. Traditionally said to descend from the San'ami Kanekuni lineage, he received the court title of Hoki no Kami in Tensho 9 (1581) at the age of nineteen. He subsequently moved to Kiyosu in Owari Province and, in Keicho 15 (1610), accompanied Tokugawa Yoshinao to Nagoya, where he became one of the founding figures of the Owari shinto tradition. In Kan'ei 10 (1633) he retired under the Buddhist name Keiyu, dying three years later at seventy-six. His personal name was Kawamura Saemon, and the majority of his extant works are shinogi-zukuri katana and wakizashi, with hira-zukuri tanto and polearms comparatively few.
Nobutaka's forge work reveals the Mino tradition of his origin: itame-hada mixed with nagare-hada, tending toward hada-dachi, with thick ji-nie and chikei. His tempering ranges from tightly controlled notare with clear nioiguchi to bold, spirited compositions in which gunome-midare, tobiyaki, and yubashiri span into the shinogi-ji, developing into hitatsura-like all-over hardening. The nie is deep and sometimes coarsely formed, yielding nie-kuzure at the yakigashira and hotsure along the habuchi, punctuated by frequent kinsuji and sunagashi. His boshi tends to be deeply tempered with long kaeri, at times assuming an ichimai-like boldness.
Among the designated pieces, the Tensho 9 katana is celebrated as an utsushi after the renowned Inabae, executed with natural assurance immediately upon receiving his court title. His imposing o-kissaki katana display the wide-bodied proportions characteristic of the Momoyama period, while even his yari of extraordinary length show no breakdown in execution, demonstrating technical mastery across blade forms.

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.

Mino in the Momoyama period
Unification closed the mass market, and Seki’s smiths moved to where the new money was: the Mishina line to Kyōto with court titles, Daidō smiths to castle towns across the provinces. Mino became the great technical ancestor of the Shintō age.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
