Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
NihontoWatchNihontoWatchSummary This blade is attributed to Daido (大道), who was active during the late Muromachi period in Mino province (today’s Gifu prefecture). While the certificate doesn’t mention its age, we made a phone call to NBTHK and confirmed that they estimated the age of this blade around the late Muromachi period. A few swordsmiths used Daido as their maker’s name during the late Muromachi-Edo period. Among Daido, the most famous Daido is Mutsu No Kami Daido (陸奥守大道). He signed as Kanemichi, forging swords in Mino province(Gifu prefecture), and moved to Kyoto in 1569. And he received the name 大(Dai) from the emperor Ogimachi for his excellent swordsmanship. And he changed his name to Dai-Kanemichi. Mino Province Mino Province is one of the most famous and historical sword-forging sites. There were so many schools forging blades during the Samurai period. The swordsmiths who resided in Mino province developed particular sword-forging tradition called MINO-DEN. Its characteristic is the TOGARI(Pointed shapes protruding from the Hamon ) in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868). MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area. Mino was located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of its practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. This blade is appraised as a Hozon Touken (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 visible kizu on the groove of the blade. Fuchi-Kashira This Fuchi Kashira has an entirely different design on each part. The Fuchi part is decorated with a geometric pattern called the Sayagata (紗綾形) design with golden paint, probably gold or brass inlay. The Sayagata (紗綾形) pattern is a design pattern of Manji (万字). Sayagata is one of the auspicious designs meaning “longevity and prosperity” because the pattern representing a large number such as 万, which means ten thousand, connected to each other is said to bring good luck. According to a theory, this motif was brought from a foreign country to Japan in the Momoyama period (1568-1600). In the Edo period, it was commonly used on figured satin and combined with designs that featured Japanese apricot blossoms, chrysanthemums, bamboos, or orchids. On the other hand, we could see that a landscape in engraved on the Kashira part. It depicts mountain scenery, and it seems golden paint was initially applied to these here and there. In addition, the same type of design is used for the Kojiri (鐺, the metal fitting that protects the tip of a scabbard). Tsuka and Menuki Although it is unsure because the judgment is based on the range that could be seen through the gaps between the knots, each Menuki probably expresses the figure of a person carrying a long, thin plant that looks like felled bamboo. There are many examples of sword mountings incorporating familiar motifs from people’s daily lives, and we think this piece is one of them. Tsuba and Habaki This antique iron Tsuba has a symmetrical shape. And its principal motif is a Kumo (蜘蛛, spider) and cobwebs. The spider depicted on the front and the object caught in the spider web depicted on the reverse are each painted in silver, and the cobwebs are depicted using gold or brass inlay techniques. As spiders nest and catch prey with their web, people considered the spider pattern had the meaning of “grabbing happiness” or “attracting things.” The cobweb was treated in Nihonshoki (日本書紀, also called as Nihongi, The Chronicles of Japan), Kokin Wakashu (古今和歌集, an early anthology of Japanese poetry) and also Heike Monogatari (平家物語, The Tale of the Heike). When the cobweb goes down in the morning, it was thought, “the person you are waiting for will come.” The spider pattern has been appreciated thanks to its beautiful nest shape and the meaning of the design. People enjoy using this motif for various items, such as Kimonos (着物, traditional Japanese costume) or ceramics. Saya This scabbard is wrapped with a gorgeously designed cloth. Its pattern is that gives an elegant impression, with a Hishi Mon (菱紋, rhombus pattern, a type of geometric pattern whose basic shape is a diamond shape) being layered with Botan Karakusa (牡丹唐草). It is a combination of Botan (牡丹, peony) flowers and the Karakusa (唐草, arabesque) pattern. Peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a kind of good-omen motif; people regarded it as a rich harvest sign. As mentioned above, a peony is called the Botan in Japanese. When we write this flower’s name in Kanji characters, its second letter means mountain hermit medicine that would give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity. The Karakusa pattern is a design in which vine stems, and leaves are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Among the Karakusa patterns, the Botan Karakusa pattern has been favored as a representative design of Karakusa patterns since the Muromachi period. Authentication Paper They authenticated the blade on June 3rd in the 4th year of Reiwa (2022). They appraised it as Hozon Touken, the blade worth preserving for Japanese society.

From the end of the Muromachi period into the early Shintō era, several Mino swordsmiths bore the name Daidō. The most prominent among them was Mutsu no Kami Daidō, whose signed and dated works survive from the Tenshō era, with recorded dates including Tenshō 2 (1574), 4 (1576), 13, and 18 (1590). Other smiths of the name carried various court titles -- Izu no Kami, Mikawa no Kami, Kawachi no Kami, and Shinano no Kami -- while still others signed without titles as "Seki-jū Daidō," "Gifu-jū Daidō," or "Heianjō-jū Daidō." Among the Mino smiths of this period, Mutsu no Kami Daidō is regarded as particularly highly skilled, "standing alongside Wakasa no Kami Ujifusa."
Daidō's forging typically shows ko-itame mixed with masame, with fine ji-nie well applied. His hamon is characteristically an ō-notare-based ko-gunome-midare, or a shallow notare mixed with ko-gunome, hakoba, and togari-ba; the nioiguchi is consistently described as tight and clear, showing lively variation, with ko-ashi and yō and adhering ko-nie. His bōshi tends toward midare-komi, turning back in a Jizō-like manner or with a pointed tendency. His sugata favors wide mihaba with imposing, dignified constructions, and he produced both katana and wakizashi in hira-zukuri. The carvings found on certain works -- including renderings of "Namu Myōhō Renge Kyō" and Kurikara -- are noted as "superb."
The NBTHK consistently describes Daidō's workmanship in jigane and hamon as "excellent," with blades that are kenzen and of especially fine quality among his oeuvre. His technical ability is characterized as "extraordinary," and the dated inscriptions on his works -- particularly the Minamoto surname and Tenshō-era dates -- are valued as significant documentary records of late-Muromachi swordsmithing in Mino Province.

Seki (関), in Mino Province, grew from two roots set down in the Nanbokuchō period and rose to become the great center of mass sword production in the late medieval age. The published sources trace the wellspring of Mino swordmaking to Kinju (whose name the commentary also reads Kaneshige), counted since antiquity among the Masamune Jittetsu, the ten disciples of Sōshū Masamune, and to Kaneuji of the Shizu line; the Kokon Meizukushi records Kinju as a native of Tsuruga in Echizen who "crossed over to Seki and resided there," carrying the Sōshū-den manner east. Beneath that Sagami inheritance lay a Yamato foundation, legible in the Tegai descent of the Seki Zensada line through Kaneyoshi, so that the Mino-den the Seki workshops forged stands as a fusion of Yamato grain and Sōshū activity in nie. From this Nanbokuchō founding the name multiplied across the Muromachi period into Sue-Seki, the last and largest body of the tradition; its representative masters at the close of the old-sword age were Magoroku Kanemoto, famed for the sanbonsugi, and Izumi no Kami Kanesada, the smith called Nosada, while the Kanefusa, Ujifusa and Daidō hands worked beside them and the move of Wakasa no Kami Ujifusa to Kiyosu carried the Mino body to the threshold of Owari shintō. A common Mino vocabulary binds the Seki body, however widely its members range. The forging is an itame that stands and runs to masame, often mixed with mokume and nagare, over which rises the cool whitish shirake-utsuri of Mino steel rather than the bright midare-utsuri of Bizen; this pale, standing jigane is the constant tell the judges read first, present alike on Kinju's Nanbokuchō katana, Kaneyoshi's Ōei tachi and Nosada's late-Muromachi blades. Over it the smiths temper gunome into which the pointed togariba of Mino enters, with ko-nie clinging to a tight nioiguchi, ashi and yō, and sunagashi streaming through; the bōshi answers in midare-komi turning to a pointed or jizō-cast ko-maru swept with hakikake. From this shared grammar the individual hands diverge.
Kanemoto fixed the regular three-cedar sanbonsugi of pointed teeth; Kanefusa devised the rounded-head, constricted-waist "Kanefusa midare"; Kinju and the early founders held a calmer, rounder gunome away from the restless Shizu line, their work laid with thicker ji-nie and dry, standing grain. The late masters carried the manner to a higher finish: Nosada wove togariba among rounder forms for a broader temper than Kanemoto's one-sided file, and turned at times to a slender Rai-styled suguha with a hidden gunome; Kaneyoshi held instead to a cool ito-suguha, the disciplined Yamato face of late Seki, lightly broken with ko-gunome. A collector seeks Seki because it is the connoisseur's ground for reading Mino-den across a vast body of signed and attributed work. The kantei runs through the jigane first: the standing, masame-leaning itame and the whitish shirake separate a Seki blade from Bizen and Yamashiro, after which the pointed togariba, the dry nie, and the pointed or jizō bōshi confirm the province; the discriminations the judges draw, Kinju held apart from Shizu by his rounder gunome, Nosada parted from Kanemoto by his breadth, give the eye its anchors. Within the school the standing of the best members is settled: Magoroku Kanemoto for the sanbonsugi, Nosada whom the swordbooks call simply "an excellent master" and the most accomplished of the several Kanesada hands, and the early Kinju as a rare and precious founding name, his record running through the Jūyō tier with the signed pieces few and the long blades attributed den. Signature works carry real provenance: a Kinju tantō presented to the Tokugawa shogunal house in 1679, a Nosada katana borne by a chief retainer of the Kii Tokugawa and a tachi forged for the father of Takeda Shingen, a Kaneyoshi tachi transmitted in the Chikuzen Kuroda family. Beyond connoisseurship, Seki's blades earned a battlefield reputation for cutting; the full hiraniku and stout build of the Sue-Seki katana, made to sever, set the wazamono standing that made Mino the working sword of its age.
