Perry’s arrival in 1853 unraveled the Tokugawa peace and created the first mass demand for working swords in two centuries. Kiyomaro, called the Masamune of Yotsuya, died on its eve; Munetsugu and Yukihide carried the boom to the end.
This Katana is made by Tairyusai Sokan, a pupil of Koyama Munetsugu, in Keio 4 (1868). The blade features a broad and thick shape with a very long and large Kissaki, and a beautiful Gunomemidare Hamon. It comes with an NBTHK Tokubetsu Hozon Token paper.

Sokan was born in the early Bunsei era (1818-1830) as the son of Ono Heizo, in the castle town of Shirakawa in Oshu. His teacher in swordmaking was Koyama Munetsugu, and his forging career appears to have begun around the end of the Tempo era (1830-1844). From around the beginning of the Kaei era he served as a retained smith of the Shimosa Furukawa Domain. Among his later works are examples signed "Abukuma-gawa Sokan," in which he adopted as a surname the Abukuma River of his native region. He began regularly using the art name Tairyusai from around Ansei 1 (1854). His residence in Edo was at Fukagawa Hakozaki. Initially cutting his signatures in kaisho (standard script), from around the eighth month of Ansei 4 (1857) he changed to reisho (clerical script). He was also adept at carving on sword blades and likely served as a capable assistant to his teacher. He continued making swords into the Meiji era, but no works are seen after the Haitorei; he died on January 23, Meiji 16 (1883).
Sokan's blades present the bold, imposing sugata characteristic of the shinshinto period: wide mihaba, thick kasane, shallow sori, and large kissaki, imparting a powerful appearance. The forging shows tightly packed ko-itame with thickly adhering ji-nie and abundant fine chikei; the faintly standing, distinctive midare-utsuri characteristic of this smith also appears. The hamon is based on choji mixed with ko-gunome, gunome, and angular-headed forms, with long ashi entering well; the temper is nioi-dominant with ko-nie and occasional ara-nie, with fine kinsuji and sunagashi, and a bright and clear nioiguchi. In his comparatively early works the choji rises and falls with pronounced variation, producing a more splendid and flamboyant effect, while later works feature a linked succession of somewhat smaller-patterned temper elements. The boshi characteristically runs in midare-komi with ko-maru and a long kaeri.
The NBTHK recognizes Sokan as a smith of high technical ability whose finest works demonstrate that capability to its fullest. His earlier pieces are noted for greater variation within the choji pattern, with the hardened edge displaying noticeable change and a more brilliant effect, while late works show the bright, clear edge standing out strikingly against the robust form. Both ji and ha in his superior examples are described as kenzen (sound and well-preserved), a recurring evaluative commendation. The cutting-test inscriptions that frequently accompany his blades, often by Iga Norishige — counted among the "Four Heavenly Kings" of late-Bakumatsu connoisseurship — are noted as possessing great documentary value, further attesting to the esteem in which Sokan's work was held among warrior patrons of the period.

Born in Kyōwa 3 (1803) at Shirakawa in Ōshū, Koyama Munetsugu (固山宗次) carried a smith's name read variously in the setsumei as Munobei or Sōbei, working under the art-names Issensai and Seiryōsai. He came up alongside elder brothers Munehira and Munetoshi, and although his teacher is traditionally given as Katō Tsunahide, the NBTHK readers repeatedly note that the hand of Katō Tsunatoshi shows through his work more plainly. He first served the Matsudaira house of Shirakawa as a retained smith; when that domain was transferred to Kuwana in Ise, he settled in Edo at Azabu Nagasaka and forged as a Kuwana domain smith. In Kōka 2 (1845) he received the court title Bizen no Suke, the signature Bizen no Suke Fujiwara Munetsugu recurring on the dated katana from that point. His production runs from the latter half of Bunsei into the early Meiji years, and the program it serves is the Bakumatsu fukko revival of Bizen-den: a deliberate return, from an Edo workshop, to the chōji tempering of the old Bizen masters. The shared idiom is consistent across the line. Construction tends to a wide mihaba, thick kasane, shallow sori and an extended chū-kissaki or ō-kissaki, giving the heavy-in-hand shinshintō bearing the readers call taihai. The ground is a tightly packed ko-itame, sometimes flowing toward nagare or masame, carrying extremely fine mijin-grade ji-nie and frequent chikei; faint utsuri rises on a number of blades.
The temper is the heart of the recognition: a nioi-dominant chōji-midare or gunome-chōji, with ko-chōji, togariba and angular heads mixed in, long ashi and yō entering, fine sunagashi and kinsuji, and a bright, clear nioiguchi. To read his hand, the setsumei flag particular chōji shapes (the kawazuko tadpole-head and the kobushi fist-shaped chōji clustered near Keiō-dated work), a midare-komi bōshi turning in ko-maru with hakikake, and the bold, thick-chiseled signatures with prominent chisel-pillows. Cutting-test inscriptions are common, several tied to the connoisseur Iga Norishige, who is recorded learning swordmaking from Munetsugu. His pupils carry the same vocabulary: Tairyūsai Sōkan (宗寛, also Munekane), son of Ōno Heizō and later a Koga/Furukawa domain smith, whose blades add a faint midare-utsuri and a smaller-pattern late temper; and the likely student Kongōsai Munehiro, who copied the same shrine original his master did. For kantei, the discriminating points are the orderly yet varied chōji arrayed shoulder-to-shoulder, the nie-laden Tenpō-era pieces whose habuchi has not yet settled, and a deliberate allusion to the second-generation Kunisuke when kobushi-like chōji appear. The named works root the line in documented copying: an utsushi of the National Treasure Koryū Kagemitsu, reconstructed to its original ubu state with kurikara and bonji carved by Sōkan; and a Tenpō 11 (1840) wakizashi copying the hōchō-shaped Masamune of Egara Tenmangū in Kamakura, carved by Tōryūsai Seiju and dedicated by Nomura Toshikatsu, a rare pairing of two Edo masters. Provenance inscriptions name patrons such as Miyake Takuma and the Furukawa domain on the Sōkan side. Across the NBTHK register, the work stands as a disciplined Edo restatement of the Bizen chōji tradition, prized for the brightness of its nioiguchi and for the documentary value of its dated, commissioned and trial-cut tangs.
