NihontoWatchNihontoWatchAntique Japanese Sword Tanto Attributed to Kashu Sanekage with NBTHK Tokubestsu Hozon Certificate 【Description】 This blade is attributed to Kashu Sanekage (加州真景), who was active in the mid – late Nanbokucho period (南北朝: 1362-1375). Kashu is the province’s name in Today’s Ishikawa prefecture, and it is also known as Kaga province. It is said that he learned the sword-forging techniques from Etchu Norishige (越中則重). Kashu has been known for many renowned swordsmiths for a ling time. Although it was not clear when the sword-forging was begun there, it is said that Sanekage was the founder of sword-forging in Kashu. When Sanekage was active in the Nanbokucho period, Japan was tumultuous because the imperial court was split into two sides(south and north). There were many conflicts, and many Samurai were deployed. And Sadatsuna must have dedicated himself to forging high-quality blades for those Samurai who fought in battles. Also, you can see interesting Kissaki (tip of the blade) called Shobu Zukuri (菖蒲造り) . There is no Yokote on this blade. Yokote is the borderline between the tip and cutting edge. We are confident you will appreciate the elegant look of this blade. Naginata Naoshi This type of blade is called Naginata Naoshi (薙刀直し). Naginata is a traditional Japanese pole sword. According to the NBTHK authentication paper, this blade was originally Naginata and was shortened as a Tanto. Naginata was once a primary weapon, but this trend changed during the Samurai period. However, it kept its presence as a Tanto. Naginata has a longer history than Katana has as a weapon. And, Naginata was highly valued among Samurai families because of its history, which led them to believe it was an excellent weapon. There is a saying in Japanese sword collectors about Naginata Naoshi. It goes, “Naginata Naoshi ni Namakura Nashi, ” roughly translated as Naginata Naoshi Katana, is never dull (always sharp). Horimono (Engraving) There is a Horimono (彫物: blade sculpture) on one side of this blade. The Horimono is one of the elements of this blade’s beauty. This pattern is the Suken (素剣). It is a simplified design of the Sanko-Duka-Ken (三鈷柄剣), which is a sword that the Fudo Myo-O (不動明王: acalanātha, one of the objects of worship in Buddhism) brings. It is an esoteric Buddhist tool used for esoteric prayer, meditation, purification, and amulets. It is believed that this sword would exorcize evil spirits. 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). This authentication paper was only given to authentic Japanese swords, especially well preserved and high quality with artistic value. *Please keep in mind that there is a couple of Kitae Kizu on the blade.

Nakago : Nakago is the tang of the Japanese sword. Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged. Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard). Fuchi-Kashira : A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt. The motif of this Fuchi Kashira is the cherry blossom (桜: Sakura).

Only one of Sanekage's signatures carries a date, and it settles almost everything known about him: a hira-zukuri tanto inscribed Fujiwara Sanekage on the omote and Joji 6, second month on the ura, the year 1367, a blade that became an Important Cultural Property and that fixes both his province and his period. Sanekage worked in Kaga in the Nanbokucho years, and the published sources count him in the line of Etchu Norishige, the smith who had carried the Soshu tradition north out of Sagami a generation or two before. They transmit him as Norishige's pupil who later moved to Kaga, but they qualify the link on the dates: Norishige's own signed works fall in the Showa and Gen'o eras at the end of the Kamakura period, while Sanekage signs Joji, two reigns later. The gap is too wide for direct discipleship, and the judges read the connection as an inherited manner rather than a master-and-student bond, a smith who took up the Norishige hand at one or two removes and made it the leading Soshu-den style of his province.
His is a nie-laden hand built on a standing itame. Over a forging of itame, often mixed with mokume and large grain, the surface stands out rather than lying flat, with thick ji-nie gathered on it and chikei entering well, the dark lines of steel that mark the Norishige descent. Onto that jigane he sets a notare mixed with gunome, the nie strong and deep, and through the temper run long sunagashi, often layered several deep, with kinsuji breaking through, hotsure fraying the habuchi, and uchinoke and yubashiri scattered along it. The boshi turns in midare-komi with frequent hakikake, finishing in a small round or sweeping to a yakizume point. It is the activity that the published sources keep naming as his tell, and they describe one greatly shortened katana as showing 「則重に直結する出来を示している」, workmanship connecting directly to Norishige.
The jigane is where his province speaks. The steel runs dark, whitish in the grain over a blackened underlying tone, a color the judges name again and again as a northern-country feeling. It is the half-step that separates him from his model: his itame does not stand as strongly as Norishige's, and against the work of the Sagami homeland the judges find his blade wanting in clarity, writing of one katana that 「相州本国の作に比してはどこか野趣が感じられる」, that compared with the works of the Soshu heartland a certain rusticity is felt in it. That rusticity is not a fault in their account but a fingerprint. The same commentary that calls his manner 「いわゆる則重風を見せている」, showing the so-called Norishige style, sets it down as the work of a country hand who inherited a great tradition and kept its vigor while losing its polish.
Two registers run through his record. The great body of it is the o-suriage mumei katana, shinogi-zukuri blades shortened from longer Nanbokucho tachi, shallow in sori, the kissaki a chu-kissaki or an o-kissaki, attributed to him from the ji and ha alone. Against these stand his rare signed pieces, all tanto and a single wakizashi, hira-zukuri and slightly sun-nobi, the long four- and five-character signatures cut with a fine chisel, several carrying devotional carving, bonji with suken or with gomabashi at the base. A few of the signed tanto are tempered instead in a purely executed narrow suguha with ko-ashi, the calm manner that sits beside his more flamboyant nie work. From the signatures themselves the judges separate generations: a first hand who signs finely and dates to Joji, and a second-generation Fujiwara Sanekage cut with a thicker chisel, judged a skilled smith second only to the first and now recorded under his own entry, so the one name probably spans more than a single lifetime.
What sets Sanekage apart is exactly the distance the published sources measure between him and Norishige. He is held to the Etchu master by the standing hada, the thick ji-nie, the chikei and the nie-laden notare, and he is held away from him by the darker steel and the northern cast, the rusticity that the heartland work does not have. The published commentary on his Important Cultural Property tanto draws the balance plainly, naming in it 「則重伝を継承した加州真景の特色」, the features of Kashu Sanekage as an inheritor of the Norishige tradition. He is not the source of that tradition but its provincial continuation, the hand through which the Soshu-den of Norishige became the nie-based style of Kaga.
For the collector Sanekage is a rare and well-defined northern name. Fujishiro grades him Jo-jo saku. He has no National Treasures; his record runs through one Important Cultural Property, the Joji 6 tanto, and through the Juyo tier, where forty-five of his blades are recorded across many sessions. The dated tanto, the judges note, is of exceptionally high documentary value because so few signed works survive, and his manner is rich in 「野趣に富み, 覇気に溢れる作域」, a workmanship full of rustic spirit and martial energy. His blades carry provenance to the Maeda, the lords of his own province of Kaga, with the dated tanto recorded in the Maeda Toshinari collection, and to the Nakagawa house. Signed Sanekage is among the scarcer things a collector of Soshu-den might hope to meet, the mumei katana coming to light from time to time and a dated signature only very rarely, a document of how the Norishige tradition lived on in the north.

The Kaga inlay tradition (Kaga zōgan) emerged in Kaga Province during the early Edo period, centered on the castle town of Kanazawa under the patronage of the Maeda clan. This distinctive form of hira-zōgan is said to have developed when craftsmen specializing in stirrup decoration (abumi-shi) adapted their metalworking techniques to tsuba and other sword fittings, flourishing from the early seventeenth century through the Kyōhō era (1716–1736). Working against polished grounds of shakudō, shibuichi, or occasionally refined copper (suaka), these artisans created works characterized by their compositional sophistication and technical precision, establishing a regional aesthetic that would influence later generations of metalworkers. The hallmark of Kaga workmanship lies in its masterful deployment of multiple colored metals—gold, silver, copper, shakudō, and shibuichi—inlaid in flat relief against dark, highly polished grounds. Motifs range from naturalistic subjects such as autumn grasses, butterflies, and mandarin ducks beneath willows to more formal designs including paulownia crests and brocade wrappers, all rendered with meticulous kebori line engraving that adds refinement to the broader inlay work.
The compositions typically extend across the entire surface of the guard, creating an effect of visual richness and decorative abundance. Against jet-black shakudō or the warm tonality of suaka, the multicolored inlays achieve a luminous clarity, producing works of elegant splendor (fūryū) that balance technical virtuosity with restrained taste. The tradition's influence extended beyond its geographic center, with works attributed to Kaga methods appearing in collections throughout Japan. Large-scale presentation pieces demonstrate the school's capacity for ambitious design, while the consistent quality of execution across surviving examples suggests a well-established workshop system with shared technical standards. Though individual makers within the tradition rarely signed their work, the distinctive aesthetic—characterized by full-surface compositions, polished dark grounds, and precise multicolor inlay—remains immediately recognizable, preserving the legacy of Kanazawa's metalworking excellence through the Edo period.
