Carried from Yamato to the northern province of Etchū, the Uda smiths kept a masame-laced tradition through two phases — the founding Ko-Uda generations of the Nanbokuchō, and the long Uda line that worked the forges into the late Muromachi.

The Etchū Uda School (宇多) Lineage
The The Etchū Uda School (宇多), active 1310–1596 in Etchū Province across 48 documented smiths: 0 Kokuhō (National Treasures), 1 Jūbun, 4 Jūbi, 1 Tokubetsu Jūyō, 121 Jūyō.
Kunifusa (國房) — Mainline · 1368-1375. Jūbi, Jūyō. Kunifusa is traditionally held to have been a son of Ko-nyudo Kunimitsu, the late Kamakura-period founder of the Uda school who migrated from Uda District in Yamato Province to Etchu. Tradition further records that Kunifusa studied under Norishige of Etchu. Together with Kunimune, he stands as a representative smith of the Uda group, and from the Nanbokucho period onward several generations continued to bear the same name, with the school flourishing down through the end of the Muromachi period. Works of the branch that does not descend later than the Nanbokucho period are broadly referred to as *Ko-Uda*. The earliest extant dated example bearing the Kunifusa signature is inscribed Koo 1 (1389), while a *Juyo Bijutsuhin* tanto dated Oei 12 (1405) provides critical documentary evidence for the school's chronology. Confirmed signed works reaching back to the late Nanbokucho period are limited to only a few examples, making such pieces especially valuable as documentary material. A separate, unrelated line of Kunifusa smiths worked at Uwajima in Iyo Province from the early Edo period, displaying a distinctly *Horikawa* manner in both workmanship and *nakago* construction.
Because the school originally came from Yamato, many works naturally display a strong Yamato temperament; at the same time, there also exist examples that appear to emulate *Soshu-den* workmanship, thought to follow earlier Etchu masters such as Norishige and Go. The forging characteristically shows *itame-hada* mixed with *mokume* and *nagare-hada*, with the grain tending to stand (*hada-datsu*); *ji-nie* adheres well with frequent *chikei*, and the steel carries a somewhat dark, *kanairo* tone recognized as distinctive of *Hokurikudo-mono* — works of the northern provinces. The *hamon* is most often a *suguha*-based temper with shallow *notare* mixed with *ko-gunome*, showing deep *nioi*, well-adhering *nie*, and activities including *sunagashi* and *kinsuji*; the *nioiguchi* is characteristically bright and clear. In places, somewhat coarse, rounded *nie* appears within the hardened edge — a hallmark of the school — while the *boshi* frequently tends toward *togari* with a deep turn-back and *hakikake*. Generally speaking, while Kunimune's works often show a somewhat standing grain, Kunifusa is frequently seen in tightly forged *jigane*, and the NBTHK has noted that "the excellence of the forging in the *jigane* is a point that warrants an appraisal to Kunifusa."
Across successive designations the NBTHK consistently affirms that Kunifusa is "regarded as one of the more accomplished smiths within the Uda group" and "one of the foremost representatives of the Uda school." His works are repeatedly described as demonstrating workmanship that is "excellent" in both *ji* and *ha*, with pieces praised as *kenzen* — sound and well-preserved — and of high completeness without imbalance. The school's prominence as "a major force in the northern provinces" is a recurring theme, and even later-generation works are acknowledged for maintaining good quality of execution. Kunifusa's oeuvre encompasses a range from subdued *suguha*-tone pieces conveying the Yamato homeland to vigorously unsettled *midare* compositions richly covered in *nie*, demonstrating that his tradition commanded both restraint and expressive breadth across its long productive span from the Nanbokucho period through the close of the Muromachi era.
Kunifusa (國房) — Mainline · 1381-1384. Jūbi. Smith of the Etchū Uda School.
Kunimitsu (國光) — Mainline · 1317-1319. Tokujū, Jūyō. Uda Kunimitsu (宇多国光), known as Ko-nyudo Kunimitsu (古入道国光), is traditionally regarded as the founder of the Uda school. According to accepted tradition, around the Bunpo era (1317–1319) he relocated from Uda District in Yamato Province to Utsu in Etchu Province, establishing a lineage that would flourish through subsequent generations. He is said to have had sons named Kunifusa and Kunimune, and subsequent smiths bearing the name Kunimitsu appear to span several generations from the late Kamakura into the Nanbokucho period. No definitively signed works by Ko-nyudo Kunimitsu himself are confirmed; however, extant tachi bearing the signature "Uda Kunimitsu" and datable to the late Kamakura period are reasonably attributed to his hand.
Blades attributed to Ko-nyudo Kunimitsu strongly display a Yamato-like character in both *jihada* and *hamon*. The forging typically shows tightly worked *ko-itame-hada*, at times with *masame-hada* mixed in toward the edge, well covered with *ji-nie* and intermingled with *chikei*. A whitish *utsuri* reminiscent of *shirake* may stand out in the *ji*. The *hamon* is characteristically *suguha*-based, occasionally exhibiting shallow *notare* with a slight admixture of small *gunome*; *ko-nie* adheres well, and *sunagashi* and *kinsuji* appear along the temper line. The *boshi* returns in *ko-maru* with *hakikake* at the tip. *Bo-hi* carved on both sides with *maru-dome* is a recurring feature.
Ko-nyudo Kunimitsu occupies a position of considerable importance as the progenitor of the Uda school, one of the principal forging traditions of Etchu Province. His work demonstrates the direct transmission of Yamato-den characteristics into a provincial setting during the late Kamakura period. Blades attributed to his hand that survive in *kenzen* condition constitute valuable reference material for understanding the formative period of the Uda tradition and the broader dissemination of Yamato forging methods into the northern provinces.
Kunimitsu (國光) — Mainline · 1362-1368. Jūyō. The Uda school traces its origin to the late Kamakura period, when the elder priest Konyudo Kunimitsu relocated from Uda District in Yamato Province to Etchu Province, thereby becoming the founder of the lineage. Kunimitsu's sons included Kunifusa and Kunimune, and the line prospered through the Nanbokucho period and onward into the Muromachi period. Works from the late Kamakura through the Nanbokucho period are generally referred to as Ko-Uda. Among blades signed Kunimitsu, there appear to have been multiple generations, with smiths succeeding to the same name into the Muromachi period.
Since the Uda group originally came from Yamato Province, their works naturally tend to show strong Yamato characteristics. The *jigane* displays *itame* mixed with *mokume*, with *chikei* appearing and well-developed *ji-nie*; the steel often shows a golden tone with some blackish coloration, becoming whitish in places. Early Ko-Uda works exhibit strong *koshizori* with *funbari* and *ko-kissaki*, while the later Oei-era Kunimitsu produces refined, slender tanto in *hira-zukuri* with *uchizori*. The *hamon* ranges from shallow *notare*-based *gunome-midare* with deep *nioi* and well-adhering *nie* to narrow *suguha* carrying a slight *ko-notare* and fine *hotsure*. The *boshi* in *o-maru* with a tendency toward *yakitsume* conveys the school's Yamato provenance.
Both the Ko-Uda founder's works and the later Oei-era Kunimitsu are consistently praised as *kenzen* and of notably high workmanship. The distinctive blackish cast within the golden-toned *jigane* and the presence of rounded *nie* within the temper are hallmarks by which the school's characteristics are clearly indicated. The earliest dated work, bearing a Gen'o 3 (1321) inscription, constitutes valuable documentary material for the study of the school's origins.
Tomonori (友則) — Mainline · 1390-1394. Jūyō. Tomonori belongs to the Uda school of Etchu Province, a lineage founded when the monk-smith Konyudo Kunimitsu migrated from Uda District in Yamato to Etchu around the Bunpo era (1317-1319) of the late Kamakura period. The school thereafter prospered through the Muromachi period, with smiths such as Kunifusa, Kunimune, and Kunitsugu active during the Nanbokucho era. According to the *meikan*, five smiths bearing the name Tomonori are recorded, beginning with one active around the Meitoku era (c. 1390) and continuing to the Eisho era (1504-1521). His surviving works are appraised as dating from the late Nanbokucho through the early Muromachi period, and the term "Ko-Uda" is applied to works from this early phase of the lineage.
Tomonori's forging is *itame-hada* mixed with *mokume*, tending toward standing grain, with abundant *ji-nie* and finely entering *chikei*; the *jigane* characteristically shows a somewhat dark "*kan'a-iro*" tone that the NBTHK assessors identify as strongly representative of "northern province" work. His *hamon* ranges from *chu-suguha* with mixed *ko-gunome* containing *ashi* and *yo* to broader patterns incorporating *gunome* and *togariba*; in his most dramatic works, *nie* is powerfully applied, with coarse particles spilling into the *ji*, while *tobiyaki* and *muneyaki* develop to reveal a *hitatsura*-like appearance. The *boshi* in such pieces forms a flame-like configuration with deep tempering and *nie-kuzure*. Even in his quieter *suguha* pieces, the *nioiguchi* is bright and *kenzen*.
Among the Uda group, for which extant works are not particularly numerous, Tomonori stands as a smith of high technical ability whose range encompasses both restrained *suguha* and boldly *nie*-laden *hitatsura*-style works. An *ubu-nakago*, signed tachi of the kind represented in the 17th-session designation is noted as particularly rare. That one of his works appears in the *Kozan oshigata* further attests to the esteem in which his blades have been held as study material for this school.

Kunihisa (國久) — Mainline · 1394-1428. Jūyō. Uda Kunihisa belongs to the Uda school, which traces its origins to the late Kamakura-period smith Konyudo Kunimitsu, who relocated from Uda District in Yamato Province to Etchu. In the Nanbokucho period smiths such as Kunifusa, Kunimune, and Kunitsugu were active, and the line flourished through successive generations down to the end of the Muromachi period. According to the sword reference compendia, Kunihisa is traditionally said to have been the son of Kunifusa (or, in some sources, Kunimune), and beginning with the Oei era there were several generations using the same name, continuing through as many as six generations down to the Bunmei era. Works that do not descend past the Nanbokucho period are termed Ko-Uda, while later works are broadly referred to simply as Uda.
Because the group originally came from Yamato Province, many works naturally display a strong Yamato temperament, and at the same time examples with a *Soshu-den* flavor also exist. The *jigane* of Kunihisa around the Oei era is characteristically a dense *ko-itame* mixed with *mokume*, with abundant *ji-nie* and finely entering *chikei*; the steel often shows a somewhat blackish tone, with a faintly whitish *utsuri*-like appearance or *shirake-utsuri* standing up. The *hamon* ranges from *chu-suguha* toned with accompanying *ko-gunome* to shallow *notare* mixed with *gunome* and angular *kakuba* elements. The school's distinctive, strongly lustrous, rounded *ha-nie* adhere thickly, and *kinsuji* and *sunagashi* run through the tempered area. The *boshi* characteristically tends toward a pointed tip with a long *kaeri* and *yakisage*, reflecting mannerisms in which the school's traits are conspicuously manifested. In both *jigane* and *hamon*, the finest Oei-era works amply display the style so characteristic of the school -- so fine, as the setsumei note, as to nearly be mistaken for that of Rai Kunimitsu or Rai Kunitsugu.
Kunihisa produced tanto, wakizashi, tachi, and even yari, all of high quality. His tanto are comparatively numerous, while tachi and uchigatana are fewer but uniformly well-crafted. His output in forms such as *kanmuri-otoshi-zukuri* further demonstrates the school's Yamato heritage. Among his extant works, the dated example of Oei 7 (1400) is the earliest recorded and constitutes valuable documentary material. Both *ji* and *ha* are consistently praised as *kenzen* and bright, and his workmanship is repeatedly described as preeminent, vividly demonstrating the high level of skill attained by the Uda group in the early Muromachi period.
Kunifusa (國房) — Mainline · 1455-1457. Jūyō. Smith of the Etchū Uda School.
Kunimune (國宗) — Mainline · 1394-1428. Jūyō. Smith of the Etchū Uda School.
Kunitsugu (國次) — Mainline · 1469-1487. Jūyō. The Uda school traces its origin to the late Kamakura period, when the monk Kunimitsu migrated from Uda District in Yamato Province to Etchu Province. Kunitsugu is a name borne by several generations within this lineage; reference works record the first as a brother of Kunifusa, active around the Enbun era (1356-1361), and the line continued through at least the Tenbun era (1532-1555). The school flourished particularly during the Muromachi period, producing a substantial body of work across long swords, tanto, and yari.
The Kunitsugu setsumei reveal a consistent Uda character: an *itame-hada* that tends toward standing grain (*hada-dachi*), sometimes mixed with *masame* or *mokume*, often with a slightly blackish tone to the *ji*. The tempering favors *ko-notare* mixed with *gunome* and *ko-gunome*, laden with clustered *nie*, frequent *sunagashi*, and intermingled *kinsuji*. A Nanbokucho-period tachi (Juyo, 23rd Session) displays "an *itame* forging with a tendency toward *masame*" and "a whitish *utsuri*," with *ko-gunome* mixed with *ko-midare* showing "abundant activities -- *ashi* and *yo*, well-formed *nie*, and *sunagashi*." A tanto of the Oei to Shocho era (Juyo, 15th Session) presents "the typical manner of Uda work from that time," with deep *nioiguchi* and thick *nie*.
The school's designated corpus includes a yari dated Bunmei 17 (1485) -- a rare signed spear predating the common Muromachi-period proliferation of such weapons -- which the NBTHK deems "valuable as important material for research into the Uda school." Across blade forms and periods, the Uda Kunitsugu works maintain a robust, *nie*-laden aesthetic tempered by the provincial vigor of their Etchu origin.

The Etchū Uda School (宇多) Lineage
The The Etchū Uda School (宇多), active 1310–1596 in Etchū Province across 48 documented smiths: 0 Kokuhō (National Treasures), 1 Jūbun, 4 Jūbi, 1 Tokubetsu Jūyō, 121 Jūyō.
Kunifusa (國房) — Mainline · 1368-1375. Jūbi, Jūyō. Kunifusa is traditionally held to have been a son of Ko-nyudo Kunimitsu, the late Kamakura-period founder of the Uda school who migrated from Uda District in Yamato Province to Etchu. Tradition further records that Kunifusa studied under Norishige of Etchu. Together with Kunimune, he stands as a representative smith of the Uda group, and from the Nanbokucho period onward several generations continued to bear the same name, with the school flourishing down through the end of the Muromachi period. Works of the branch that does not descend later than the Nanbokucho period are broadly referred to as *Ko-Uda*. The earliest extant dated example bearing the Kunifusa signature is inscribed Koo 1 (1389), while a *Juyo Bijutsuhin* tanto dated Oei 12 (1405) provides critical documentary evidence for the school's chronology. Confirmed signed works reaching back to the late Nanbokucho period are limited to only a few examples, making such pieces especially valuable as documentary material.

The *hamon* is most often a *suguha*-based temper with shallow *notare* mixed with *ko-gunome*, showing deep *nioi*, well-adhering *nie*, and activities including *sunagashi* and *kinsuji*; the *nioiguchi* is characteristically bright and clear.

Kunifusa (國房) — Mainline · 1381-1384. Jūbi. Smith of the Etchū Uda School.
Kunimitsu (國光) — Mainline · 1317-1319. Tokujū, Jūyō. Uda Kunimitsu (宇多国光), known as Ko-nyudo Kunimitsu (古入道国光), is traditionally regarded as the founder of the Uda school. According to accepted tradition, around the Bunpo era (1317–1319) he relocated from Uda District in Yamato Province to Utsu in Etchu Province, establishing a lineage that would flourish through subsequent generations. He is said to have had sons named Kunifusa and Kunimune, and subsequent smiths bearing the name Kunimitsu appear to span several generations from the late Kamakura into the Nanbokucho period. No definitively signed works by Ko-nyudo Kunimitsu himself are confirmed; however, extant tachi bearing the signature "Uda Kunimitsu" and datable to the late Kamakura period are reasonably attributed to his hand.
Blades attributed to Ko-nyudo Kunimitsu strongly display a Yamato-like character in both *jihada* and *hamon*. The forging typically shows tightly worked *ko-itame-hada*, at times with *masame-hada* mixed in toward the edge, well covered with *ji-nie* and intermingled with *chikei*. A whitish *utsuri* reminiscent of *shirake* may stand out in the *ji*. The *hamon* is characteristically *suguha*-based, occasionally exhibiting shallow *notare* with a slight admixture of small *gunome*; *ko-nie* adheres well, and *sunagashi* and *kinsuji* appear along the temper line. The *boshi* returns in *ko-maru* with *hakikake* at the tip. *Bo-hi* carved on both sides with *maru-dome* is a recurring feature.
Ko-nyudo Kunimitsu occupies a position of considerable importance as the progenitor of the Uda school, one of the principal forging traditions of Etchu Province. His work demonstrates the direct transmission of Yamato-den characteristics into a provincial setting during the late Kamakura period. Blades attributed to his hand that survive in *kenzen* condition constitute valuable reference material for understanding the formative period of the Uda tradition and the broader dissemination of Yamato forging methods into the northern provinces.
Kunimitsu (國光) — Mainline · 1362-1368. Jūyō. The Uda school traces its origin to the late Kamakura period, when the elder priest Konyudo Kunimitsu relocated from Uda District in Yamato Province to Etchu Province, thereby becoming the founder of the lineage. Kunimitsu's sons included Kunifusa and Kunimune, and the line prospered through the Nanbokucho period and onward into the Muromachi period. Works from the late Kamakura through the Nanbokucho period are generally referred to as Ko-Uda. Among blades signed Kunimitsu, there appear to have been multiple generations, with smiths succeeding to the same name into the Muromachi period.
Since the Uda group originally came from Yamato Province, their works naturally tend to show strong Yamato characteristics. The *jigane* displays *itame* mixed with *mokume*, with *chikei* appearing and well-developed *ji-nie*; the steel often shows a golden tone with some blackish coloration, becoming whitish in places. Early Ko-Uda works exhibit strong *koshizori* with *funbari* and *ko-kissaki*, while the later Oei-era Kunimitsu produces refined, slender tanto in *hira-zukuri* with *uchizori*. The *hamon* ranges from shallow *notare*-based *gunome-midare* with deep *nioi* and well-adhering *nie* to narrow *suguha* carrying a slight *ko-notare* and fine *hotsure*. The *boshi* in *o-maru* with a tendency toward *yakitsume* conveys the school's Yamato provenance.
Both the Ko-Uda founder's works and the later Oei-era Kunimitsu are consistently praised as *kenzen* and of notably high workmanship. The distinctive blackish cast within the golden-toned *jigane* and the presence of rounded *nie* within the temper are hallmarks by which the school's characteristics are clearly indicated. The earliest dated work, bearing a Gen'o 3 (1321) inscription, constitutes valuable documentary material for the study of the school's origins.
Tomonori (友則) — Mainline · 1390-1394. Jūyō. Tomonori belongs to the Uda school of Etchu Province, a lineage founded when the monk-smith Konyudo Kunimitsu migrated from Uda District in Yamato to Etchu around the Bunpo era (1317-1319) of the late Kamakura period. The school thereafter prospered through the Muromachi period, with smiths such as Kunifusa, Kunimune, and Kunitsugu active during the Nanbokucho era.

Kunihisa (國久) — Mainline · 1394-1428. Jūyō. Uda Kunihisa belongs to the Uda school, which traces its origins to the late Kamakura-period smith Konyudo Kunimitsu, who relocated from Uda District in Yamato Province to Etchu. In the Nanbokucho period smiths such as Kunifusa, Kunimune, and Kunitsugu were active, and the line flourished through successive generations down to the end of the Muromachi period. According to the sword reference compendia, Kunihisa is traditionally said to have been the son of Kunifusa (or, in some sources, Kunimune), and beginning with the Oei era there were several generations using the same name, continuing through as many as six generations down to the Bunmei era. Works that do not descend past the Nanbokucho period are termed Ko-Uda, while later works are broadly referred to simply as Uda.
Because the group originally came from Yamato Province, many works naturally display a strong Yamato temperament, and at the same time examples with a *Soshu-den* flavor also exist. The *jigane* of Kunihisa around the Oei era is characteristically a dense *ko-itame* mixed with *mokume*, with abundant *ji-nie* and finely entering *chikei*; the steel often shows a somewhat blackish tone, with a faintly whitish *utsuri*-like appearance or *shirake-utsuri* standing up. The *hamon* ranges from *chu-suguha* toned with accompanying *ko-gunome* to shallow *notare* mixed with *gunome* and angular *kakuba* elements. The school's distinctive, strongly lustrous, rounded *ha-nie* adhere thickly, and *kinsuji* and *sunagashi* run through the tempered area. The *boshi* characteristically tends toward a pointed tip with a long *kaeri* and *yakisage*, reflecting mannerisms in which the school's traits are conspicuously manifested. In both *jigane* and *hamon*, the finest Oei-era works amply display the style so characteristic of the school -- so fine, as the setsumei note, as to nearly be mistaken for that of Rai Kunimitsu or Rai Kunitsugu.
Kunihisa produced tanto, wakizashi, tachi, and even yari, all of high quality. His tanto are comparatively numerous, while tachi and uchigatana are fewer but uniformly well-crafted. His output in forms such as *kanmuri-otoshi-zukuri* further demonstrates the school's Yamato heritage. Among his extant works, the dated example of Oei 7 (1400) is the earliest recorded and constitutes valuable documentary material. Both *ji* and *ha* are consistently praised as *kenzen* and bright, and his workmanship is repeatedly described as preeminent, vividly demonstrating the high level of skill attained by the Uda group in the early Muromachi period.
Kunifusa (國房) — Mainline · 1455-1457. Jūyō. Smith of the Etchū Uda School.
Kunimune (國宗) — Mainline · 1394-1428. Jūyō. Smith of the Etchū Uda School.
Kunitsugu (國次) — Mainline · 1469-1487. Jūyō. The Uda school traces its origin to the late Kamakura period, when the monk Kunimitsu migrated from Uda District in Yamato Province to Etchu Province. Kunitsugu is a name borne by several generations within this lineage; reference works record the first as a brother of Kunifusa, active around the Enbun era (1356-1361), and the line continued through at least the Tenbun era (1532-1555). The school flourished particularly during the Muromachi period, producing a substantial body of work across long swords, tanto, and yari.
The Kunitsugu setsumei reveal a consistent Uda character: an *itame-hada* that tends toward standing grain (*hada-dachi*), sometimes mixed with *masame* or *mokume*, often with a slightly blackish tone to the *ji*. The tempering favors *ko-notare* mixed with *gunome* and *ko-gunome*, laden with clustered *nie*, frequent *sunagashi*, and intermingled *kinsuji*. A Nanbokucho-period tachi (Juyo, 23rd Session) displays "an *itame* forging with a tendency toward *masame*" and "a whitish *utsuri*," with *ko-gunome* mixed with *ko-midare* showing "abundant activities -- *ashi* and *yo*, well-formed *nie*, and *sunagashi*." A tanto of the Oei to Shocho era (Juyo, 15th Session) presents "the typical manner of Uda work from that time," with deep *nioiguchi* and thick *nie*.
The school's designated corpus includes a yari dated Bunmei 17 (1485) -- a rare signed spear predating the common Muromachi-period proliferation of such weapons -- which the NBTHK deems "valuable as important material for research into the Uda school." Across blade forms and periods, the Uda Kunitsugu works maintain a robust, *nie*-laden aesthetic tempered by the provincial vigor of their Etchu origin.
