Yamato masame in the service of the Date. The first Kunikane, sent by Date Masamune to study under Echizen Yasutsugu, revived the pure masame-hada of the ancient Hōshō school — straight grain running the full length of the blade — and founded a line that served the Sendai domain through the whole of the Edo period.
The The Sendai Kunikane School (仙台國包), active 1624–1860 in Rikuzen Province across 3 documented smiths: 0 Kokuhō (National Treasures), 1 Jūbun, 4 Jūbi, 1 Tokubetsu Jūyō, 38 Jūyō.
Phase 1 · The Sendai Kunikane School (仙台國包) · 1624 – 1860
Kunikane (國包) — Mainline · 1624-1644. Jūbun, Jūbi, Tokujū, Jūyō. The shodai Kunikane was born Hongō Genzō in Bunroku 1 (1592) at Kokubun-Wakabayashi in Sendai, Mutsu, and entered the service of Date Masamune as a retained smith. By his lord's command he went up to Kyoto and studied under Etchū no Kami Masatoshi; in Kan'ei 3 (1626) he received the court title Yamashiro Daijō, and he styled himself a descendant of the later line of Yamato Hōshō Gorō. That self-styling is the key to him. In the opening decades of the Shintō period, when the Sōshū manner in itame and mokume was the fashion of the day, Kunikane set himself against the current and gave his whole working life to reviving the *masame*-forging, *suguha*-tempering Hōshō-den of old Yamato. The published sources describe a hand that never wavered from that purpose, and the modern designation record bears it out: of the blades on record every signed example is in his own name, with not a single unsigned attribution among them.
His characteristic hand is constant to the point of being unmistakable. The forging is a tightly packed *masame-hada*, at times running into *nagare*, carrying fine *ji-nie* thickly applied and frequent *chikei*, the steel notably clear. A *mizukage* often rises from below the *machi*, and the published sources name this rising water-shadow a personal habit of the smith, calling it on one wakizashi a feature that 「初代国包の手くせといえる」, the kind of small confirming detail that settles an attribution. Over that *jigane* he tempers a *suguha* or *suguha-chō*, frequently broad, shallow in *notare*, the *nioiguchi* deep and bright. The activity is the Yamato kind rather than the Bizen: along the *habuchi* runs general *hotsure*, with *kinsuji* and *sunagashi* set freely into the line, *kuichigai-ba*, *nijūba* and *uchi-noke* mixed in, and *ko-ashi* entering.
The *jigane* is where he is read first and where he is most himself. Fine *ji-nie* and the abundant *chikei* over a clear, well-packed *masame* recur on nearly every blade, the forging only growing more refined as it tightens. The *bōshi* is the Yamato finish, running straight into a *yakizume*-like point with vigorous *hakikake*; the published sources find an archaic fragrance in it even where the rest of a blade is plain. On this last point they are candid in a way that is unusual for designation commentary: measuring him against the early Hōshō, they name where he falls short, citing 「物打上の変化に乏しいことと、帽子が平凡な点にある」, a relative want of variation in the *monouchi* and a commonplace *bōshi*. The same entry holds that the quality of both *ji* and *hamon* on his representative dated katana is nonetheless excellent.
One consistent hand divides into two registers by the shape it takes. The standard work is the *shinogi-zukuri* katana, *ubu* and long-signed, very often dated, with a high *shinogi*, shallow *sori* and an elongated *chū-kissaki*, over which the broad bright *suguha* sits on the tight *masame*; his dated tachi and katana from Kan'ei 4 and Kan'ei 9 are the touchstones for studying his oeuvre. The rarer register is the *hira-zukuri* wakizashi, of which the published sources note that very few survive, prizing them as reference pieces. On these the same temper opens out: the upper half takes a somewhat broader *yakiba*, the *nie* thickens and coarsens in places, *tobiyaki* resembling *yubashiri* appear, the *nioiguchi* tends toward *shizumi*, and the carvings, a plain *suken* and a *katana-hi* with *soe-hi*, are cut with deep channels that reproduce a feature of old Yamato work. Of the Onikiri wakizashi the commentary says it is a piece in which 「初代国包の本領が遺憾なく発揮された」, the smith's true strengths brought forth without reserve.
What sets Kunikane apart in his own period is exactly this fidelity to an older province. The published sources record that 「作風は一貫して大和保昌伝に終始し」, his manner kept to the Yamato Hōshō tradition from first to last, forging *masame* and tempering *suguha* with *uchi-noke*, *hotsure* and *sunagashi*, the *nie* well adhered and the *bōshi* tending to *yakizume*. His bright *masame* and Yamato finish set him against the Sōshū-fashion smiths around him, and his disciplined *suguha* over a clear *jigane* distinguishes him from the kotō Hōshō he revered, whose *monouchi* and *bōshi* he could not quite equal. He retired in Shōhō 2 (1645) and handed the headship to his eldest son Kichiemon, the second-generation Yamashiro no Kami Kunikane, founding a Sendai Kunikane line that carried the *masame* Hōshō-den to the end of the Edo period; the shodai remains the standard against which the later generations are judged.
For the collector he is a Shintō name of real standing. The published record runs through one Important Cultural Property, two prewar Jūyō Bijutsuhin and twenty-nine blades in the Tokubetsu Jūyō and Jūyō tiers, thirty-three designated works on record in all, every one of them signed. There are no National Treasures. His finest, an *ubu*, signed and dated katana preserved in its original form and held in the Uwajima Date family, the published sources call equal to or surpassing the old Hōshō, 「古保昌に優るとも劣らぬ作域」, and a masterpiece of imposing presence. His provenance is grounded in the houses he served and a few long-private hands: the Date and the Uwajima Date families above all, with recorded blades reaching the Imperial collection and the keeping of named collectors such as Kimura Sadazō. A signed shodai Kunikane is not beyond a serious collector's reach in the way a great Kamakura master is, yet the blades are mostly held rather than traded, the *hira-zukuri* wakizashi rarest of all, and a dated example in good state comes to market only from time to time. When one does, it is a clear and self-contained document of how, in an age that had turned to Sōshū, one Sendai smith chose instead to forge his way back to old Yamato.
Kunikane (國包) — Mainline · 1644-1648. Jūbi, Jūyō. Yamashiro-no-kami Fujiwara Kunikane, the second of the Sendai line, was born in Keicho 17 (1612), succeeded to the house in Shoho 2 (1645) at the age of thirty-four, received the Yamashiro-no-kami title in Kanbun 7 (1667), and died in Kanbun 12 (1672) aged sixty-one. He was the eldest son of the founder, the shodai Yamashiro-daijo Kunikane, who claimed descent from the late line of Yamato Hosho, served Date Masamune of Sendai, and by his lord's order went up to Kyoto to study under Etchu-no-kami Masatoshi before receiving the Yamashiro-daijo title in Kanbun 3 (1626). The Kunikane name was the standing forge of the Date house, and across both generations its identity rests on a single inherited manner: the masame forging of the Yamato Hosho tradition, tempered in suguha. The published sources call this his hereditary specialty, the family's transmitted Hosho-style masame at which he was particularly accomplished in the straight temper, and they rate the second generation a master of suguha second only to his father.
His hand is recognized first in the jigane. The blade is a shinogi-zukuri katana with iori-mune, the curvature shallow in the Kanbun manner and the kissaki medium, and over its whole length runs a masame-hada forged tight and well ordered, with ji-nie laid and chikei entering along the masame. This straight-grain jigane is the first of the two Hosho marks, a forging almost no other Shinto school takes as its default, and the second mark is set into it: a chu-suguha frayed at the habuchi into hotsure, mixing kuichigai-ba and a tendency to nijuba, with sunagashi and kinsuji running freely along the masame, the nioi deep and the nioiguchi bright and clear with ko-nie. Where the suguha and the masame both appear on every blade on record, the two together are the surest reading of the smith.
The boshi runs straight, sweeping into hakikake, and closes as often in a yakizume without turnback as in a small round, a Yamato-Hosho boshi habit that follows from the masame and the suguha rather than against them. To this inherited core the published sources add a tell peculiar to the Kunikane hand, and name it as such: a mizukage rising from below the hamachi, a faint pale reflection that on the broad, slightly long late blades connects and runs as an utsuri-like aspect across the lower half. Of one Kanbun katana they write that 「区下より水影が立っているが、初代同様二代にも見る手くせであり」, a habit seen in the second generation as in the founder, and they note alongside it that the nakago file is sometimes finished as a plain, simplified kesho, another of the points to watch in his work. On that same wide blade the masame stands a little on the ura, the ji-nie laid dust-fine and thick, the chikei finely formed.
Against the calm suguha the published sources record that the second generation also leaves a gunome-midare. On these the chu-suguha base mixes in small gunome and a shallow notare, ashi entering and the habuchi frayed, and one wide, long blade carries a suguha that swells into a large, shallow undulation with ko-nie and ara-nie and a nijuba tendency. The sources frame this as the exception within a hand whose default is the straight temper, writing that 「家伝の保昌流の柾目鍍を得意とし」 he was particularly skilled at suguha, with slight gunome-midare seen at times besides. A small register within the corpus carries the founder's own signatures rather than the second generation's, the go Yokei and the title Yamashiro-daijo: blades signed Yamashiro-daijo Fujiwara Yokei Kunikane, one dated Keian 1 (1648), in the same Hosho idiom but read with a founder's accent, the koshi-zori standing high with funbari, the masame tending to stand, the suguha a ko-nie chu-suguha damp and frayed with sunagashi following.
What sets his work apart within the broad world of Kanbun Shinto is not a flourish but the consistency of the Hosho reading: the masame carried the length of the blade, the quiet suguha laid over it, the swept yakizume boshi, and the mizukage below the machi. The published sources keep his standing honestly relative to the founder. They write of one second-generation katana that it is in fact forceful and that its quality is 「殆んど初代に劣らない」, scarcely inferior to the first generation, and of his masame finest pieces that some approach the shodai while his ordinary technique does not equal him. The signature itself is a connoisseur's field: in the second generation's mei the horizontal strokes are driven hard and pressed at their close so that they read like the character ichi, and within the character 包 the inner element is cut in a distinctive form, both, the sources say, important features when reading a Kunikane signature.
Kunikane is rated Jo-saku by Fujishiro. His record is held entirely in the Juyo tier, ten katana of the second generation on record there, with two further blades under the founder's Yokei signature reaching the prewar Juyo Bijutsuhin. He holds no National Treasure and no Important Cultural Property, so the work that can be encountered is the designated Juyo katana, and these come to market only from time to time and with patience, a steady Sendai-Shinto name rather than a rarity locked wholly away. The published sources single out the well-forged, in-the-style pieces as typical and representative of the second generation, one of which, worn at the side of Kan Shinbei, carries a gold-inlaid cutting-test inscription dated Kanbun 11 (1671) and is valued as a documentary representative work. Of his quietest masame katana the sources write that it is 「上品に静温に仕上げている」, finished with refined elegance and a quiet warmth. Among recorded owners of his blades are Kurokawa Fukusaburo and the Kurokawa Institute for Ancient Cultures, which hold the two Yokei-signed Juyo Bijutsuhin, and Itaya Taneo.
