The Yamato schools grew up in the shadow of Nara’s great monasteries: Tegai took its name from a gate of Tōdaiji. Their austere masame and quiet suguha are a temple aesthetic, prized ever since for exactly that restraint.
This is a katana attributed to Ryumon Nobuyoshi from the late Kamakura period, around the Bunpo era. It features a prestigious itosuguha hamon with utsuri and a masamehada jitetsu mixed with itame. The blade is o-suriage, indicating it was originally a longer tachi, and comes with an NBTHK Hozon certificate.

Nobuyoshi is the one famous name of the Ryūmon group, a branch of Yamato swordsmiths active from the late Kamakura period into the Nanbokuchō. The published sources are nearly unanimous on his origins: "Nobuyoshi is traditionally said to have been a smith descending from the Senjuin line"[[c:1]], and because he lived at Ryūmon-shō in Yoshino District, on the road that runs from Yoshino through to Uda, he was given the byname Ryūmon Nobuyoshi. The group is said to have included other smiths, with names such as Nagayoshi and Yoshiyuki appearing in the reference works, but only Nobuyoshi became well known, to the degree that, as one Jūyō commentary puts it, "when one speaks of Ryūmon, it refers to Nobuyoshi"[[c:2]]. No dated blade by him survives; the swordbooks place him around the Shōō or Bunpō eras.
The hand that defines him is not one manner but two, and the NBTHK draws the division on nearly every paper. One mode forges "a lively midare, or a suguha-toned temper into which chōji-ashi enter"[[c:3]], with utsuri standing in the jigane and a Bizen character coming forward. The other is a suguha that frays into hotsure, in which "utsuri does not stand and the Yamato color is strongly shown"[[c:4]], quiet and austere in feeling. His finest signed tachi, the wide-bodied piece once held by the Hori viscount and treasured by Inukai Bokudō, is the showy mode at its best: a wide suguha-chō with shallow notare, mixing gunome, chōji, togariba and angular elements, ashi and yō entering, the nioiguchi tightening with ko-nie, nijūba and uchi-noke worked in, with kinsuji and fine sunagashi. The published sources call it "foremost among works by the same hand"[[c:5]].
The jigane is the constant that carries both modes. It is a well-forged itame that flows and inclines to masame, with thick ji-nie laid finely and chikei entering frequently, the masame strengthening toward the edge on the most Yamato of his blades. Over that jigane the utsuri is the variable: on the Bizen-leaning blades a clear midare-utsuri, sometimes a soft nie-utsuri; on the Yamato blades none at all. The bōshi runs straight and finishes in hakikake, often yakizume, sometimes a ko-maru with a short turnback, and across nearly the whole record the nioiguchi is bright and clear. Even in the lively mode the temper stays suguha-based with chōji and gunome set into it rather than opening into a free chōji-midare, so the bright suguha with hotsure and kuichigai-ba is the Yamato root that holds the two manners together.
His signature divides as his workmanship does. Two ways of cutting the right element of the character 延 are observed, a blocky kaisho form resembling an abbreviated 正 and a cursive sōsho form resembling 氏; the published sources record that later writers "call the former Masa-Nobuyoshi and the latter Uji-Nobuyoshi"[[c:6]]. The distinction is not merely calligraphic, for the sources note that blades with the former signature tend to a more tightly knit hada and those with the latter to a more standing grain, and one signed tachi is read as a transitional piece between the two. Signed works are set with a large two-character mei and survive in only a small number, so a genuine in-mei Nobuyoshi is a precious thing to encounter.
What places him is exactly this position between two traditions. His bright midare-utsuri and chōji-ashi set the Bizen-leaning mode apart from the plainer Senjuin and Taima suguha, while the subdued suguha-with-hotsure keeps him within Yamato. The published sources observe that his smaller-signature blades have since old times been confused with Ko-Bizen Ko-Ichimonji work, and that confusion is itself the measure of where he stands. On the mumei katana, which form the bulk of his record, the judges affirm the attribution from the high-shinogi construction, the flowing masame-inclined forging and the bright suguha alone, calling one such blade a full expression of "the characteristic features and merits of Ryūmon Nobuyoshi in both ji and ha."
For the collector he is a rare early Yamato name carried by a single great work. Fujishiro grades him Jō-jō saku. A signed tachi transmitted as an imperial possession of Emperor Go-Mizunoo is a National Treasure, and the published sources say plainly that "the presence of this celebrated masterpiece has contributed greatly to the high reputation of Nobuyoshi"[[c:7]]; two further signed tachi are Important Cultural Properties, one of them preserved at Shitsukiyama Shrine in Yamaguchi. These are heritage held in shrine and institution and are not encountered on the market. His blades carry distinguished provenance recorded on their own papers, the Hori viscount and Inukai Tsuyoshi on the Tokubetsu Jūyō tachi, the Date of Sendai and the Uesugi among the Jūyō. Beyond the locked tier his record runs through one Tokubetsu Jūyō, the Jūyō and the prewar Jūyō Bijutsuhin, some twenty-six blades in the Tokubetsu Jūyō and Jūyō ranks all told, most held rather than traded. A signed example comes to light only seldom and a fine mumei attribution from time to time, so a privately held Ryūmon Nobuyoshi is a notable thing for a collector, a document of how Yamato and Bizen met in one Yoshino hand.

Among the five schools of the Yamato-den, Senjuin (千手院) is held to be the earliest in origin, its name drawn from the Senjudo, a hall enshrining Senju Kannon (the Thousand-Armed Avalokitesvara) said to have stood at the western foothills of Mt. Wakakusa in Nara. The smiths who gathered in that quarter, working under the patronage and within the orbit of the great temples, formed the group, and their close association with the warrior-monks of the monastic establishments is thought to account for the scarcity of signed work that marks the school across its whole span. Old transmitted writings name two masters of the late Heian period, Yukinobu and Shigehiro, though no secure example by either has been confirmed; the oldest surviving signed piece is a tachi cut with the three-character inscription "Senjuin," placed in the early Kamakura period. Blades prefixed Ko-Senjuin are assigned to the earliest phase and retain the lingering presence of the straight-sword (chokuto) tradition, material indispensable to the study of how the curved shinogi-zukuri blade took form. Production runs from the late Heian period through the Nanbokucho era. The school's vocabulary is rooted firmly in Yamato practice. The jigane is an itame mixed with mokume and passages of nagare-masame, often tending toward hada-dachi, with thick ji-nie adhering well, abundant chikei, and in finer examples a faint nie-utsuri that leaves the steel bright and clear; the masame gathers and strengthens toward the edge on the most Yamato of the blades. The hamon is fundamentally a suguha with a shallow notare tendency, mixing ko-choji, ko-gunome, and ko-midare, the habuchi fraying into hotsure with uchi-noke, nijuba, kuichigai-ba, and yubashiri worked in profusion; thick ko-nie lies along a clear nioiguchi, while kinsuji and sunagashi run vigorously through the ji and ha. The boshi enters straight and forms a ko-maru with vigorous hakikake, or finishes in yakizume.
Within this shared foundation the hands diverge. Yoshihiro is singled out as the smith whose ji and ha vary most, his nie especially strong, swelling from the school's quiet suguha into a flamboyant large midare with kinsuji and sunagashi that reads toward Soshu. Sukemitsu gathers ko-choji, ko-gunome, and small midare on a bright suguha-cho, a Bizen-leaning admixture set against the school's plainer temper, his bold two-character mei itself a mark of the hand. Nobuyoshi of the Ryumon group, a Yamato branch, divides between a lively midare carrying utsuri and a Bizen character and a subdued suguha fraying into hotsure in which the Yamato color stands strongest. To kantei a Senjuin blade is to read its position among its neighbours, and the long-standing rule holds that within the Yamato Five Schools a hamon of unusually vigorous and changeable character should be appraised as Senjuin, against the more restrained tempers of Tegai, Shikkake, Taima, and Hosho. The masame in the ha, the hotsure, kuichigai-ba, and nijuba, and the yakizume or hakikake boshi keep the work within Yamato, while the brightness of the nioiguchi and the ko-midare on the edge set it apart from the plainer suguha of its sister schools. Surviving forms span tachi, katana, kodachi, ken, and yari, the ken notably numerous because they served as goshintai and ritual implements rather than weapons of the warrior class; many blades keep their ubu nakago, with pronounced koshizori and funbari of archaic bearing. Yoshihiro's dated signatures give him a face among many anonymous hands, his manner the touchstone for Soshu-tinged mumei attributions; Nobuyoshi is carried to high standing by a single great signed tachi held as an imperial heritage; Sukemitsu is anchored by a dated reference tachi in the Tokyo National Museum. The bulk of the school's record is mumei, the attributions resting on construction, the flowing masame-inclined forging, and the bright suguha alone, and provenance runs through religious institutions such as Tanzan Shrine and Kyoo Gokoku-ji (To-ji), attesting to the school's monastic roots.
