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.
NihontoWatchNihontoWatchMunetsugu was born in 1803 in Oshu Shirakawa, and it is said that he studied under Kato Tsunahide. After the domain was transferred to Seishu Kuwana, he resided in Edo and was active as a swordsmith for the Kuwana domain. In Koka 2, he received the title of Bizen no Suke. His style was consistently Bizen-den, succeeding in firing choji midare with a nioi-gachi structure on a beautiful, well-tightened jitetsu. This work has a wide mihaba, thick kasane, and a grand sugata with a boshi that is a slightly extended chu-kissaki, well-representing the period style of the Bakumatsu. The jitetsu is a tightened ko-itame with fine jinie, and the hamon is fired primarily in choji midare, mixed with gunome, angular ha, and togari-ba. It is an excellent work showing a flamboyant style with frequent ko-ashi and a wide variety of mixed structures in a nioi-gachi composition.

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.

Bakumatsu: the last war market
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.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
