This is a tanto by Momokawa Nagayoshi, likely from the Joji era (1362-1368). The blade features a sugu-midare hamon on the omote and inverted gunome on the ura, with ayasuji hada and itame hada. It comes with a gold gilt habaki, shirasaya with saya-gaki by Kotoken Kajihara, and a storage bag.

Nagayoshi is the swordsmith of the Momokawa (桃川) group of Echigo province, working in the Nanbokucho period, and he survives in only a small number of signed Juyo blades. Momokawa is a place-name in Echigo, and the published sources record that smiths styling themselves Nagayoshi (長吉) continued there for two, perhaps three generations from the Nanbokucho into the Muromachi period. Their output was scarce, and among the extant works there are no dated examples, so the several generations who bore the name cannot be told apart. One tradition makes him a pupil of Kanro Toshinaga (甘呂俊長) of Echigo, but the published sources set that tradition gently aside on the workmanship, finding little in his work that resembles Toshinaga and reading the ji and ha as Yamato (大和風) in character instead. He is therefore read not by his teacher line but by his own hand, which is consistent across the three forms in which he survives, a tanto, a wakizashi and a tachi.
That hand is, before anything else, a Yamato hand carried into Echigo steel. Over the body the published sources describe a suguha (直刃) base, narrow on some blades and wide on others, the habuchi frequently frayed with hotsure (ほつれ), and along it sunagashi (砂流し) and kinsuji (金筋) run while the nioiguchi stays bright. It is a quiet, restrained temper, far from the showy choji of contemporary Bizen, and the persistent hotsure and the streaming sunagashi are exactly what mark the work as Yamato rather than Bizen. The boshi follows the same idiom, swept with hakikake and turning sharp at the point on the tachi and wakizashi, or finishing in a small ko-maru (小丸) with kinsuji on the tanto, tempered down long on both faces. The jigane carries the same antiquity as the temper, an itame (板目) mixed with mokume (杢) that runs and flows into a nagare grain (流れ肌), standing slightly toward hada-dachi (肌立), and on the wakizashi the flow opens into an ayasugi (綾杉) appearance, the steel tending whitish (白け). This standing, flowing, whitish ji is the constant of the work, the feature that ties the three forms together and the one that separates the Momokawa hand from the Bizen smiths of the same period.
The surviving blades divide into two registers of the one manner. The rarer is the signed tachi, a shinogi-zukuri blade with koshizori and a chu-kissaki, almost ubu, that cuts the long signature toward the mune and carries narrow grooves (細樋) along the shinogi with a plain suken (素剣) in raised relief; over its tight itame the suguha mixes small gunome (小互の目), with chikei (地景) and a bright nioiguchi[[c:1]]. The more numerous register is the hira-zukuri tanto and wakizashi, broad and of slightly extended proportions (寸延び), the tanto with a finely chiseled two-character mei (二字銘) below the mekugi-ana and the wakizashi with the place-name in a five-character signature (五字銘); on the wakizashi a grass-style Kurikara (倶利迦羅) is carved on the omote and a bonji (梵字) with gomabashi (護摩箸) on the ura. Of the wakizashi the published sources judge that it well demonstrates his characteristic style, writing that the blade 「長吉の作風をよく示しており」, the suguha-cho with frequent hotsure and sunagashi taken as the very signature of his manner. The generational question is left open, the literature recording dated examples of the Joji era (貞治) while the extant tachi and tanto are exceedingly few and undated.
For the collector, Nagayoshi is a thin and quiet name rather than a celebrated one, and the honest measure of him is the small body of work on record. The reference texts place him in the Toko Taikan but record no Fujishiro grade, and there is no National Treasure, no Important Cultural Property and no Tokubetsu Juyo among the designated work; the official record runs to three Juyo blades, the tanto, the wakizashi and the tachi by which his hand is read, with no provenance to daimyo houses recorded among them. The signed pieces that survive were held privately, in Niigata and in Shizuoka, when they passed shinsa, and a Momokawa Nagayoshi is met only rarely and almost always signed. Of the tanto the published sources note that it is 「同名中でも時代が古く」, an early and rare survival of the name, while of the rare signed tachi they write 「現存数少ない長吉在銘の太刀として」 its value as reference material is extremely high. When one comes before a student of the northern provinces it is a quiet find rather than a landmark, valued for what the published sources call it, 「長吉研究の好資料の一口である」, an honest and uncommon way to hold the Yamato manner as it was practised far from Yamato, on the Echigo coast.

The Momokawa school takes its name from the locality of Momokawa in Echigo Province, where a small group of swordsmiths worked from the Nanbokucho period into the Muromachi era. Kanro Toshinaga, the figure most closely associated with the school's origins, is traditionally transmitted as a disciple of Takagi Sadamune of Goshu (Omi Province), though the NBTHK has consistently questioned this lineage, observing that Toshinaga's extant signed works -- exceedingly rare tachi and tanto -- bear little technical resemblance to Sadamune's manner. Rather, the examiners conclude that Toshinaga was a nearly contemporaneous smith whose aesthetic belongs entirely to the Yamato tradition. Momokawa Nagayoshi, recorded as Toshinaga's student, similarly shows minimal stylistic debt to his supposed teacher; his jiba is thoroughly Yamato in character, reflecting a distinct regional idiom that appears to have developed semi-independently in Echigo. Together with Heianjo Nagayoshi, who descends from the lineage of Heianjo Mitsunaga and represents a late Muromachi continuation in Yamashiro, these smiths form a loose constellation united less by direct master-pupil transmission than by a shared allegiance to Yamato-derived forging and tempering methods transplanted into provincial settings. The collective technical identity of the Momokawa group is defined by a pronounced nie-dominant aesthetic rooted in the Yamato tradition. Across the school's principal smiths, the forging consistently presents itame-hada mixed with mokume or nagare-hada, with a marked tendency toward masame -- standing grain that the NBTHK identifies as a defining characteristic of Toshinaga's hand and that recurs in Momokawa Nagayoshi's tightly executed, slightly whitish steel. Thick ji-nie and abundant chikei are universal hallmarks, producing surfaces of considerable depth and complexity. In tempering, the school favors nie-laden patterns built on ko-notare, shallow notare, or fundamentally suguha-based modes mixed with ko-gunome, uniformly enriched by vigorous hotsure, sunagashi, and kinsuji that run through the tempered zone with conspicuous energy.
Tobiyaki and yubashiri extend into the ji in Toshinaga's works, while Momokawa Nagayoshi's tempering is distinguished by persistent hotsure and a bright, clear nioiguchi. The boshi across the group consistently shows hakikake -- a feature the NBTHK singles out as diagnostic of Toshinaga and that echoes through Nagayoshi's midare-komi with pointed turnback. Heianjo Nagayoshi's late Muromachi production, while introducing gunome with angular turns and a tightened nioiguchi that inclines toward nioi, nonetheless retains the ji-nie, chikei, and Yamato-inflected grain structure that bind the group together. His occasional departures into hitatsura-like Soshu-flavored work remain distinguishable from true Soshu-den by the characteristically tight nioiguchi that marks the school's identity. The Momokawa school occupies a distinctive position within the broader history of Japanese swordmaking: a provincial tradition whose documented origins lie in Omi and Echigo rather than in the Yamato heartland, yet whose aesthetic -- described consistently by the NBTHK as exhibiting a "distinctly Yamato temperament" -- places it firmly within that lineage of restrained, nie-dominant craftsmanship. Signed works by all members are described as exceedingly rare, and each surviving blade carries exceptional documentary value for the study of medieval swordsmithing outside the major production centers. Toshinaga's works are praised as "truly brimming with haki (martial spirit)," while Momokawa Nagayoshi's few surviving pieces constitute irreplaceable records of Echigo-province traditions that left only the slightest trace in the historical canon. The school's legacy resides not in prolific output or stylistic innovation but in the faithful transmission of Yamato principles into provincial workshops, demonstrating that the tradition's characteristic austerity and nie-driven vigor could flourish far from its geographic origins.
