The Edo Nara School (奈良) Lineage
The The Edo Nara School (奈良), active 1650–1850 in Edo across 76 documented smiths: 0 Kokuhō (National Treasures), 9 Jūbun, 24 Jūbi, 13 Tokubetsu Jūyō, 131 Jūyō.
Yasuchika (安親) — Mainline. Jūbun, Jūbi, Tokujū, Jūyō. Tsuchiya Yasuchika (土屋安親), also known as Yagohachi, was born in Kanbun 10 (1670) as the son of Tsuchiya Chuzaemon, a retainer of the Shonai domain in Dewa Province. While still young he entered the school of Shoami Chinku, married his teacher's daughter, and in Genroku 16 (1703), at the age of thirty-four, went to Edo, where he undertook further training under Nara Tatsumasa — at which point, as the NBTHK setsumei consistently observe, "his innate talent fully blossomed." Around the Shotoku era he entered the service of Matsudaira Daigaku-no-kami, a nephew of Tokugawa Mitsukuni and lord of the twenty-thousand-*koku* Moriyama fief in Oshu. In Kyoho 16 (1731), at the age of sixty-one, he took the tonsure and adopted the art name Tou (東雨). He left numerous masterpieces to the world and was later celebrated — together with Nara Toshihisa and Sugiura Joi — as one of the "Three Masters of Nara" (*Nara sansaku*), recognized as an artist of the very highest ability.
Yasuchika's technical range is exceptional. His oeuvre encompasses work in iron, *shakudo*, *shibuichi*, brass (*shinchu*), and refined copper (*suaka*), with surfaces treated as polished grounds (*migaki-ji*), hammered textures (*tsuchime-ji*), and stone-grain finishes (*ishime-ji*). His signature carving methods include *sukidashi-bori* modeled relief, *takabori* high relief, the thread-fine line work of *kebori*, and — more rarely — the single-stroke *katakiribori* incision. Polychrome metal inlay (*iroe*) in gold, silver, shibuichi, and suaka is deployed with what the NBTHK describes as "an unrivaled equilibrium in compositional planning and in the exquisitely balanced placement of colored metals." His iron *tsuba* frequently employ the distinctive *daigaku-gata* form conceived for his patron, while his *kozuka* demonstrate the capacity to "draw forth a small universe" within a confined surface. In later works signed Tou, NBTHK examiners identify an austere, detached realm (*kotan*) — a shift from the vigorous pictorialism of his Edo-period maturity toward something "profoundly rich in nuance."
Across the designation records, certain evaluative themes recur with striking consistency. The NBTHK praises Yasuchika's "warm, humane sentiment" and "gentle humanism," visible in his treatment of figures such as Jurojin, Daruma, and the creatures that populate his compositions — faces rendered with "an unmistakable mildness," animals depicted so as to seem "almost alive." His narrative scenes are likened to hanging paintings (*ichifuku no e*), unfolding atmospheric effects "akin to watercolor." Whether rendering a carp amid turbulent waves, wild geese descending in rain, or Li Bai gazing at a waterfall, Yasuchika's compositions are praised for their "outstanding" interlinked design across front and back, their "free and untrammeled manner, calm and unforced," and a compositional intelligence in which "tension and relaxed release coexist." In subject, technique, and the sustained refinement of his carving, the setsumei affirm that his is an art in which, as one examiner concludes, "the sharpness of Yasuchika's skill is scattered throughout."
Toshinaga (利寿) — Mainline. Jūbun, Jūbi, Tokujū, Jūyō. Nara Toshihisa (奈良利寿), commonly known as Tahee or Taheibei (太兵衛), was born in Kanbun 7 (1667) and died in Genbun 1 (1736) at the age of seventy. He stands as the eldest and, by broad scholarly consensus, the most technically accomplished of the celebrated *Nara sansaku* — the Three Masters of Nara — alongside Tsuchiya Yasuchika and Nara Jōi. As head master of the Nara school during the mid-Edo period, Toshihisa defined the mature idiom of the lineage at its creative zenith. His oeuvre is dominated by *fuchi-kashira* sets, which constitute the great majority of his surviving work; *tsuba* and *kozuka* by his hand are notably scarce, lending such pieces exceptional documentary value when they surface. Several of his compositions — gamecocks, Jurojin with *minogame*, Shoki and oni, and tigers amid waterfalls — recur across multiple authenticated works, establishing a recognizable thematic vocabulary that later generations of the school would emulate.
Toshihisa's technical command is most fully expressed in his mastery of *sukidashi takabori*, a method of relief carving in which figures are raised from the ground plane with subtly graduated levels of height, producing an illusion of spatial depth within the severely limited surface area of sword fittings. His grounds are themselves works of considered craftsmanship: he employed a distinctive personal *ishime-ji* texture on *shakudo*, iron, and brass plates alike, and also worked polished *shibuichi* and *oborogin* grounds finished with selective applications of lacquer to deepen tonal contrast. His deployment of *irogane* — colored-metal inlay and overlay using gold, silver, *shakudo*, *shibuichi*, and *suaka* — is characteristically restrained; rather than saturating a composition with polychrome display, he applies *iroe* sparingly to heighten dramatic tension. In his battle and animal subjects, figures carved in emphatic high relief appear to thrust outward from the metal surface, while surrounding elements are rendered at lower relief planes, creating a dynamic interplay between foreground and ground that NBTHK examiners have repeatedly described as uniquely characteristic of his manner.
Toshihisa's significance within the history of Japanese metalwork extends beyond technical virtuosity. His figural subjects — whether the fierce combative energy of a gamecock poised to strike, the coiled tension of a tiger surveying its prey in the manner described as *koshitan-tan*, or the serene authority of Bishamonten commanding a narrow *kashira* face — consistently achieve an expressive intensity that transcends mere decorative function. NBTHK scholarship has emphasized his singular ability to convey the philosophical duality of *do* (movement) and *sei* (stillness) within a single composition: a quality that elevates his finest works from accomplished craft to genuine artistic statement. Several of his pieces bear distinguished provenance, including examples from the Ryushido collection of Mitsumura Toshimo with inscriptions by the celebrated Meiji-era metalworker Unno Shomin. As the senior figure among the Nara sansaku, Toshihisa established the standard of dignified, powerfully carved relief work against richly textured grounds that came to define the school's highest aspirations.
Joi (乗意) — Mainline. Jūbi, Tokujū, Jūyō. Sugiura Joi (1701-1761), known by the art name Issando, trained under Juei in the lineage of Nara Toshiharu and rose to become one of the celebrated "Three Masters of Nara" (*Nara sansaku*) alongside Toshihisa and Yasuchika. Born in Genroku 14, he also used the names Sen'emon and Eishun throughout his career. His place within this triumvirate secured his lasting reputation as one of the foremost independent metalworkers of the mid-Edo period, working outside the patronage structures that governed the Goto house.
Joi is most closely identified with *nikuaibori*, a modulated relief-carving technique he developed into a personal specialty of unrivaled refinement. Through subtle variations in height and volume, he coaxed remarkably expressive surfaces from bare metal grounds, often completing entire compositions through chisel work alone, dispensing with *zogan* (inlay) and *iroe* (colored metal accents). His preferred format was the *kozuka*, where *nikuaibori* found its fullest expression on *oborogin* polished grounds. He also employed *kebori* (fine line engraving) for textures such as fur and flowing water, and incisive *katakiribori* for sharp geological forms. When he did turn to inlaid techniques, as in his *fuchi-kashira* sets on brass or plain copper (*suaka*) grounds, his *takabori* (high relief) and *sukidashi-bori* displayed equal mastery, with precisely modulated gold and *shakudo* inlay enhancing the sculptural depth.
Joi's *tsuba* are recognized as extremely rare, making any authenticated example a significant survival. His most celebrated subject, the lion casting its cub into Chigiri Valley, exists in closely related versions across multiple designations and is published in the canonical reference *Tagane no Hana*. Whether rendering the anxious gaze of a parent lion or the lively expressions of Chinese boys at play, Joi's work is distinguished by its immediacy and the sheer expressive authority of his chisel.
Tou (東雨) — Mainline. Jūbun. Smith of the Edo Nara School.
Shozui (政随) — Mainline. Jūbi, Jūyō. Hamano Masayuki was an outstanding talent among the disciples of Nara Toshihisa and was commonly known as Tarobei. He trained many pupils and established the Hamano school as one of the principal lineages of urban metalworkers (*machibori*), thereby founding an independent tradition comparable in stature to the Yokoya school. As recorded in the *Edo Kinko Meifu*, he "thundered through the world," gaining widespread fame as one of the "Four Heavenly Kings of Nara" (*Nara Shitenno*). He used numerous art names throughout his career, including Otsuryuken, Miboku, Kankei, Rifudo, Yukotei, Shuhosai, Hankeishi, Isshunan, and others. Among his followers, artists such as Kakusui, Naosui, and Masaryo are known as excellent craftsmen who carried forward the lineage.
Masayuki's technique was highly esteemed, and he excelled in every approach — whether in bold *sukidashi-bori*, *nikiai-bori*, *nikubori*, or *katakiribori*. His manner is characterized, as the *Soken Kisho* appraises it, by a preference for "the challenging," through which he reveals a bold spirit; his work is "brisk and forceful." While inheriting the style of his master Toshihisa and incorporating mannerisms associated with Joi and Yasuchika, he devised an individual sculptural approach, adding distinctive nikubori-like modeling to high-relief subjects. The Hamano school's characteristic manner — using vertically oriented compositions and placing the principal subject in a large, forceful arrangement realized through realism — was firmly transmitted within the lineage.
In his later years, Masayuki left many powerful works that can be called distinctly his own, making vigorous use of robust high relief. His late pieces, often signed with age statements recording his seventies, fully display what the NBTHK describes as "the true essence of his art through the vigorous deployment of his powerful carving techniques." Works from this final period combine daring with attentiveness, their polychrome *iroe* accents executed with great care, standing as eloquent testaments to his elevated technical skill and the enduring vitality of the tradition he founded.
Sekibun (赤文) — Mainline. Jūyō. Katsurano Sekibun, who employed the art name Yurakusai, was born in Kansei 2 (1790) at Murakami in Echigo Province. As a young man he traveled to Edo and studied under the Hamano family, acquiring the foundational discipline of that distinguished lineage. From his adoption of the art name Yurakusai, it is further conjectured that he undertook training in Kyoto, broadening his technical and aesthetic formation beyond a single school. In Bunsei 7 (1824) he entered the service of the Sakai family of Shonai domain as a retained artisan (*kakae-ko*), and from Koka 2 (1845) onward he settled permanently in Tsuruoka, where he continued to work until his death in Meiji 8 (1875) at the remarkable age of eighty-seven. For his inscriptions he used a distinctive cursive hand modeled on the calligraphic style of Kameda Bosai, the celebrated scholar of his native Echigo.
Sekibun devoted himself to the study of Tsuchiya Yasuchika, refining his skills with that master's example as his ideal, and produced an oeuvre in which *tsuba* are especially numerous. For the ground metal he frequently employed iron and *shakudo*, and he "excelled especially at applying *iroe* to a style of strongly modeled high-relief carving." His technical repertoire further encompassed *sukidashi-bori*, *katakiribori*, *nikuai-bori*, and various forms of *zogan* (inlay). Among pictorial subjects he favored animals and birds, with tigers and newts (*imori*) counted as particular strengths. His celebrated "Dawn Crow" (*Akegarasu*) *tsuba*, conceived as the sky at daybreak with *suaka* ground and *shakudo suemon-zogan* crows beating toward the sun, is singled out by the NBTHK alongside his octagonal newt-design *tsuba* as among his finest achievements.
The NBTHK consistently characterizes Sekibun's work as possessing a "high degree of refinement" in both composition and carving method, praising his "compositional command and carving skill" as "truly superb." His productions are recognized for their distinctive vitality -- an intensity of expression deemed "indeed characteristic of Akafumi" -- realized through the full mobilization of a wide range of carving methods together with inlay and polychrome metalwork techniques. Whether working on intimate *tsuba* or ambitious multi-component *soroi kanagu* such as his Twelve Zodiac fitting set, Sekibun's works are commended as fully demonstrating the "sharpness of the maker's abilities," securing his place as one of the most accomplished provincial metalworkers of the late Edo period.

Noriyuki (矩随) — Mainline. The first-generation Hamano Noriyuki (矩随), also read as Norizui, was a direct disciple of Hamano Shōzui (政随), the outstanding Edo-period metalworker who stood as a leading representative of the Nara school of *kinkō*. Among Shōzui's pupils, Noriyuki distinguished himself most prominently, earning the high praise of having surpassed his teacher. He employed several art names over the course of his career, including Bōsaiken, Bōsōken, and Kaiundō. Together with his adopted son, the second-generation Noriyuki (who signed as Shōjuken), he is renowned as one of the foremost masters representing the Edo Nara-school lineage.
Noriyuki's technical signature is his mastery of *usunikubori* — thin, precisely controlled relief carving — combined with richly varied *iroe* in gold, silver, *shibuichi*, and *suaka*. Within the Nara school, the continuation of the manner of Toshiaki and Shōzui is clearly evident in his work, particularly in the modeling of figural facial features, which are rendered in distinctly higher relief than their surroundings — a hallmark of the school. His favored grounds include polished *oboro-gin* and *shakudō chirimen-ishime*, and he demonstrates equal command of *takabori*, *nikuai-bori*, *sukidashi-bori*, and *nikiai-bori*. Compositions exploit open space with superb control, treating subjects ranging from Buddhist iconography and the Six Immortal Poets to Tatar horsemen and pastoral scenes with a refined sensibility.
The NBTHK consistently characterizes Noriyuki's works as demonstrating "refined sensibility and technique to their fullest extent," noting compositions of "superb compositional scheme" that "skillfully exploit open space." His depictions of sacred and literary subjects are praised for their "profound solemnity" and expressive richness. The designating body identifies his mature works as "excellent examples from Noriyuki's fully matured period," affirming his position as a master who carried the Nara-school tradition forward with both technical authority and artistic distinction.

Works from this final period combine daring with attentiveness, their polychrome *iroe* accents executed with great care, standing as eloquent testaments to his elevated technical skill and the enduring vitality of the tradition he founded.
Sekibun (赤文) — Mainline. Jūyō. Katsurano Sekibun, who employed the art name Yurakusai, was born in Kansei 2 (1790) at Murakami in Echigo Province. As a young man he traveled to Edo and studied under the Hamano family, acquiring the foundational discipline of that distinguished lineage. From his adoption of the art name Yurakusai, it is further conjectured that he undertook training in Kyoto, broadening his technical and aesthetic formation beyond a single school. In Bunsei 7 (1824) he entered the service of the Sakai family of Shonai domain as a retained artisan (*kakae-ko*), and from Koka 2 (1845) onward he settled permanently in Tsuruoka, where he continued to work until his death in Meiji 8 (1875) at the remarkable age of eighty-seven. For his inscriptions he used a distinctive cursive hand modeled on the calligraphic style of Kameda Bosai, the celebrated scholar of his native Echigo.
Sekibun devoted himself to the study of Tsuchiya Yasuchika, refining his skills with that master's example as his ideal, and produced an oeuvre in which *tsuba* are especially numerous. For the ground metal he frequently employed iron and *shakudo*, and he "excelled especially at applying *iroe* to a style of strongly modeled high-relief carving." His technical repertoire further encompassed *sukidashi-bori*, *katakiribori*, *nikuai-bori*, and various forms of *zogan* (inlay). Among pictorial subjects he favored animals and birds, with tigers and newts (*imori*) counted as particular strengths. His celebrated "Dawn Crow" (*Akegarasu*) *tsuba*, conceived as the sky at daybreak with *suaka* ground and *shakudo suemon-zogan* crows beating toward the sun, is singled out by the NBTHK alongside his octagonal newt-design *tsuba* as among his finest achievements.
The NBTHK consistently characterizes Sekibun's work as possessing a "high degree of refinement" in both composition and carving method, praising his "compositional command and carving skill" as "truly superb." His productions are recognized for their distinctive vitality -- an intensity of expression deemed "indeed characteristic of Akafumi" -- realized through the full mobilization of a wide range of carving methods together with inlay and polychrome metalwork techniques. Whether working on intimate *tsuba* or ambitious multi-component *soroi kanagu* such as his Twelve Zodiac fitting set, Sekibun's works are commended as fully demonstrating the "sharpness of the maker's abilities," securing his place as one of the most accomplished provincial metalworkers of the late Edo period.

Noriyuki (矩随) — Mainline. The first-generation Hamano Noriyuki (矩随), also read as Norizui, was a direct disciple of Hamano Shōzui (政随), the outstanding Edo-period metalworker who stood as a leading representative of the Nara school of *kinkō*. Among Shōzui's pupils, Noriyuki distinguished himself most prominently, earning the high praise of having surpassed his teacher. He employed several art names over the course of his career, including Bōsaiken, Bōsōken, and Kaiundō. Together with his adopted son, the second-generation Noriyuki (who signed as Shōjuken), he is renowned as one of the foremost masters representing the Edo Nara-school lineage.
Noriyuki's technical signature is his mastery of *usunikubori* — thin, precisely controlled relief carving — combined with richly varied *iroe* in gold, silver, *shibuichi*, and *suaka*. Within the Nara school, the continuation of the manner of Toshiaki and Shōzui is clearly evident in his work, particularly in the modeling of figural facial features, which are rendered in distinctly higher relief than their surroundings — a hallmark of the school. His favored grounds include polished *oboro-gin* and *shakudō chirimen-ishime*, and he demonstrates equal command of *takabori*, *nikuai-bori*, *sukidashi-bori*, and *nikiai-bori*. Compositions exploit open space with superb control, treating subjects ranging from Buddhist iconography and the Six Immortal Poets to Tatar horsemen and pastoral scenes with a refined sensibility.
The NBTHK consistently characterizes Noriyuki's works as demonstrating "refined sensibility and technique to their fullest extent," noting compositions of "superb compositional scheme" that "skillfully exploit open space." His depictions of sacred and literary subjects are praised for their "profound solemnity" and expressive richness. The designating body identifies his mature works as "excellent examples from Noriyuki's fully matured period," affirming his position as a master who carried the Nara-school tradition forward with both technical authority and artistic distinction.
