NihontoWatchNihontoWatchThis blade bears the signature “Kanemoto” (兼元). The accompanying NBTHK Tokubetsu Hozon certificate attributes it specifically to Magoroku Kanemoto (孫六兼元), the renowned 2nd generation Kanemoto. The name Kanemoto (兼元) was borne by several generations of distinguished swordsmiths from Mino Province (present-day Gifu Prefecture). Among them, the most celebrated is the 2nd generation Kanemoto (二代兼元), widely known by the honorary nickname Magoroku Kanemoto (孫六兼元). Active during the late Muromachi period (16th century), he is regarded as one of the greatest masters of the Mino tradition, alongside the renowned Kanesada (兼定). His works are admired not only for their exceptional craftsmanship but also for their historical importance during one of the most turbulent periods in Japanese history. During the Sengoku period (戦国時代), Mino Province developed into one of Japan’s foremost centers of sword production. As warfare became increasingly frequent, demand grew for swords that combined durability, sharp cutting ability, and practical battlefield performance. The swordsmiths of the Mino tradition responded by refining forging techniques that emphasized strength, reliability, and efficiency while maintaining a high level of artistic refinement. As a result, Mino blades gained an outstanding reputation among samurai throughout Japan and became one of the most influential sword-making traditions of the late Muromachi period. Historical records indicate that Magoroku Kanemoto first worked in Akasaka (赤坂) before later moving to Seki (関), which had become the leading center of sword production in Mino Province. His blades were highly esteemed by many prominent warriors, including Toyotomi Hideyoshi (豊臣秀吉). Although relatively little is known about his personal life, the enduring reputation of his work speaks eloquently to his extraordinary skill. The prestige of his name was such that successive generations continued to sign their works as “Kanemoto,” establishing one of the longest-lasting lineages among Mino swordsmiths. One of the defining characteristics of the Kanemoto lineage is the distinctive Sanbonsugi (三本杉) hamon—a rhythmic series of sharply pointed gunome resembling rows of cedar trees. While later generations continued to produce this characteristic pattern, it is the 2nd generation Magoroku Kanemoto who is traditionally credited with perfecting and popularizing this iconic style. Today, the Sanbonsugi hamon remains one of the most recognizable and celebrated temper patterns in the history of Japanese swords, and it continues to inspire swordsmiths and collectors alike. The influence of Magoroku Kanemoto extends far beyond the Muromachi period. His name has become synonymous with exceptional sharpness, masterful craftsmanship, and the enduring spirit of the Japanese sword. Even today, “Magoroku” (孫六) remains widely recognized throughout Japan and has been adopted for well-known knife brands and other traditional products, reflecting the lasting prestige associated with one of the greatest masters of the Mino tradition. For collectors and connoisseurs alike, authentic works by the Kanemoto lineage represent not only remarkable examples of Japanese swordsmithing but also enduring symbols of the martial culture and artistic excellence of the Sengoku era. It 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 the blade. Fuchi-Kashira This fuchi-kashira set seems to depict a scene from everyday life in the past. On the fuchi, there is a figure wearing traditional garments, holding a folding fan, and appearing to perform a dance, possibly as part of a celebratory event. Floral decorations and gold accents are applied throughout the design. The background is textured with fine nanako-style granulation, and the carving is highlighted by the use of multiple metals, creating a detailed and three-dimensional appearance. Tsuka and Menuki The menuki seems to depict a heron (鷺, sagi), a graceful water bird. In Japanese tradition, the heron symbolizes noble character because it stands elegantly and unstained even in the muddy waters of rivers and rice fields. The heron is also regarded as an auspicious bird in classical Chinese art. For example, a painting that combines a heron, lotus, and drunken hibiscus is believed to represent a future filled with happiness, wealth, and prosperity. Tsuba and Habaki This tsuba features an openwork design depicting pine branches together with small birds and a monkey. In Japanese art, the pine tree symbolizes longevity and resilience. Birds often represent good fortune or peace, while monkeys are traditionally viewed as clever animals that help ward off misfortune. These motifs were commonly used in sword fittings as familiar and auspicious elements. Pine trees remain green throughout the year, enduring both intense heat and severe cold. Because of this, their pattern has long been regarded as a symbol of eternal youth. The deep greenish-brown color associated with pine is called Tokiwa-iro (常盤色), and pine trees are also known as Tokiwa-gi (常盤木). The word tokiwa means “unchanging,” so Tokiwa-iro expresses a wish for longevity and prosperity. This color was especially valued in the Edo period as a good-luck color. The pine motif conveys an elegant and noble impression, which may be another reason it has been so beloved for centuries. Saya We estimate the surface of this Saya is decorated with the Ishime-Ji (石目地). Its base was hit by Tagane (鏨, chisel for metalworking), and it makes a rough surface that seems stone. Authentication Paper They authenticated the blade on August 22nd in the 20th year of Heisei (2008). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society.

Among the Mino smiths of the late Muromachi period the published sources name Kanemoto, beside Kanesada, as one of the two representatives of the Seki tradition. The name was carried by several generations, but it is the second, the smith the world singles out as Magoroku Kanemoto, who is held the most technically accomplished, and whose bold two-character signed blades fix the kantei. He worked at Akasaka in Mino, where the family used Magoroku as its hereditary common name; the long signatures reading "Nōshū Akasaka-jū Kanemoto" with dates in the Meiō and Eishō years anchor the first generation, while the niji-mei pieces are read as this prized second hand. There are no examined two-character signed examples bearing a date, so the published commentary places his attribution on the manner of the signature and on the temper rather than on a year-mark, and frankly notes that distinguishing the generations is not yet settled.
The core of his work is the hamon called sanbon-sugi, the togariba (three-cedar) temper he is credited with originating, a run of pointed gunome forged in linked clusters. What the judges return to, blade after blade, is that the second generation does not rule it into uniform threes: "the heads of the gunome become rounded in places, showing change, and the hallmark is that the pattern is not standardized"[[c:1]]. The temper rises and falls in a cursive, gyōsō line, breaking from threes into the "twos, fours and fives" the commentary calls nihonsugi, yonhonsugi and gohonsugi[[c:2]], where the later generations of the line grow sharp-angled and geometric. Ashi enter well, the nioiguchi is nioi-dominant and bright, sunagashi runs through, and on his finest blades kinsuji, yubashiri and tobiyaki gather; one published entry singles a katana out as "an especially cursive, freely irregular sanbon-sugi, the most among works of this same hand"[[c:3]].
The jigane is the Mino constant beneath that temper. It is an itame mixed with mokume, flowing and standing a little with a masame-leaning tendency, fine ji-nie adhering and chikei entering, over which rises the whitish shirake-utsuri of Seki steel, the misty reflection that marks a Mino blade. The bōshi answers the edge: it runs in midare-komi to a jizō-like small round, the return often leaning, with hakikake at the point. The sugata is robust and practical, a Sue-Seki sword made for use: shinogi-zukuri katana of somewhat wide body with strong sakizori and an extended chū-kissaki, and hira-zukuri tantō with mitsu-mune and uchizori.
Not every blade keeps the sanbon-sugi. A small group leaves it for a quiet suguha, which the commentary treats as proof of range rather than the norm; of one katana it remarks that "Kanemoto tempers a suguha, rare for him"[[c:4]], and dates such as Daiei 7 and Kyōroku 2 on these pieces supply the scarce year-marks that documentation otherwise lacks. One suguha tantō is judged a Rai-utsushi, an emulation of Kyoto work that "evokes Kaneyuki"[[c:5]], elegant in shape and in ji and ha; the published note adds that a tell of the smiths working in this Rai manner is the leaning bōshi, which the blade shows. Carvings are uncommon in his work, and bonji in particular are rare, recorded on a single wakizashi.
What sets the second generation apart is therefore drawn from his own work, not from a borrowed comparison: the rounded, cursive sanbon-sugi that refuses to become a template, the bright nioiguchi over a Seki jigane, and the leaning jizō bōshi. The published commentary repeatedly places him at the head of the Sue-Seki smiths, calling individual blades typical yet outstanding work of Magoroku Kanemoto, and reading the geometric, ruled sanbon-sugi as the mark of the later generations he stands before.
Fujishiro grades him Jō-jō saku. Thirty designated works stand on record, with no National Treasure, no Important Cultural Property and no Tokubetsu Jūyō blade among them: twenty-seven Jūyō Tōken; one Jūyō Bijutsuhin, the so-called Aoki Kanemoto said to have cut down Magara Masataka at the Battle of Anegawa; and two katana recorded in Honma's inventory of the Imperial collection. That inventory, illustrating both in sanbon-sugi, adds that Kanemoto also made suguha and rarely hitatsura, but that sanbon-sugi was the temper he did best[[c:6]]. His provenance reads as a roll of warrior houses that prized a cutting blade: the Echizen Matsudaira, the Yagyū family, Tani Tateki, and Makishima Kenmotsu Akishige, whose ownership is recorded in the gold-inlaid inscription that gives one katana the name Sasatsuyu Kanemoto. Because almost nothing in this body of work sits in the locked tiers, a signed Magoroku Kanemoto is among the more attainable of the genuinely famous koto names, yet a fine, soundly preserved niji-mei example with documented provenance comes to market only from time to time, and is a notable thing for a collector to encounter when it does.

Kanemoto (兼元) worked at Akasaka in Mino Province, and the line takes its place among the smiths of the late Muromachi period whom the NBTHK registers under the Mino-den tradition centered on Seki. The setsumei place the family within the Sue-Seki (Sue-Mino) milieu, naming Kanemoto alongside Kanesada as the two leading figures of the province in this era; one tantō note instead pairs the name with Kaneshiba, and another with Izumi no Kami Kaneshige, marking the company the line kept. The name passed through successive generations, and the records repeatedly state that distinguishing each generation has not been definitively settled. Dated long signatures reading "Nōshū Akasaka-jū Kanemoto" survive from the Meiō, Bunki, Daiei, Kyōroku, and Eishō eras, while two-character signatures bear no date. The first generation is documented through pieces dated Meiō 6, 8, 9, and 10, all giving the Akasaka residence; the most accomplished hand, and the one the world singles out under the sobriquet "Magoroku Kanemoto," is the second generation. The shared vocabulary of the line is the sanbonsugi (three-cedar) gunome, a sequence of linked pointed crests that rise and fall in groups. The ground is Mino-den through and through: itame-hada mixed with mokume and flowing masame, tending toward standing grain (hada-dachi), with fine ji-nie, chikei, and a whitish shirake-utsuri that the setsumei call out again and again. The temper mixes togariba (pointed elements) and gunome, is nioi-dominant with ko-nie, and runs sunagashi, kinsuji, and occasional tobiyaki; the bōshi is typically midare-komi turning in ko-maru, often described as Jizō-like with hakikake or a falling kaeri. The chief means of separating the second generation from the later line is regularity: as the generations descend, the pointed crests grow sharply angular and standardized, whereas Magoroku's sanbonsugi is deliberately uneven, the gunome heads rounded in places, and the pattern shifts freely into nihonsugi, yonsugi, and gosugi groupings of two, four, and five. The records describe this as a gyōsō (cursive, free) manner.
The first generation, by contrast, does not emphasize sanbonsugi at all, favoring gunome mixed with gunome-chōji and at times yubashiri and tobiyaki; both generations also made suguha, and one tantō is an uncommon Rai-utsushi in elegant straight temper that evokes Kaneyuki. For kantei, the line is read through the standing Mino grain, the shirake-utsuri, and above all the irregular sanbonsugi, with the leaning bōshi a noted point: the records observe that the honka model and these blades share a bōshi that falls over. Named and documented works recur across the register. A naginata dated Kyōroku 1 (1528) carries the full Akasaka signature and is valued as documentary source material, dated two-character pieces being scarce. A katana bearing a kinzōgan inscription on the reverse is known as "Sasatsuyu Kanemoto" and is recorded in the hands of Makishima Kenmotsu Akishige, of the same clan as Furuta Kosukezaemon. The "Aoki Kanemoto," a second-generation work, is said to be the sword with which Aoki Ichishige, a retainer of Tokugawa Ieyasu, killed Magara Masataka of the Asakura side at the Battle of Anegawa in Genki 1 (1570). A further katana carries a Genna 1 (1615) kinzōgan cutting-test inscription by Nakagawa Saheita reading "two bodies," and one suguha katana descended in the Echizen Matsudaira family. Two katana signed Kanemoto are recorded in Honma's inventory of the Imperial collection. Across these works the line is registered as the cutting-edged representative of Sue-Seki, its hand recognized wherever the three-cedar temper runs uneven over standing Mino steel. Learn more →
