NihontoWatchNihontoWatchTetsu kitae meji tatemaru gata sayu o-sukashi uzumaki mon kin zogan kaku mimi koniku ryohitsukubo jitate In the late Edo period, amidst the decline of the various houses of Hirata, Hayashi, Nishigaki, and Shimizu, it was Fukanobu of the Kamiyoshi family and the master Jinzaemon Rakuju who adorned the end of Higo tsuba. Rakuju was born in Kumamoto in Bunka 14 and, until his death in Meiji 17, served as the third generation of the Kamiyoshi family; he is a tsubako who gained great popularity and was highly praised for his tetsu kitae, shape, zogan methods, and sukashi, which are reminiscent of the early Edo Higo kinko Hayashi Matashichi. Among Rakuju's tetsu-ji, there are those with a visible kitae hada commonly referred to as "gamahada," which shares commonalities with Matashichi; old texts state "its appearance is like clouds, or like the skin of a toad, or like the root of a taro," suggesting that he took Matashichi as his model and applied various ingenious techniques to the tetsu hada. The true essence of Higo tsuba lies in the method of coloring the iron, and it is said that Rakuju's sabitsuke was meticulously applied, with his techniques reaching the pinnacle of research into the Matashichi den, resulting in particularly excellent workmanship. This tsuba is one such example, finished with Rakuju's unique kitae and sabitsuke techniques, which, coupled with the spiral-shaped kin zogan, radiates the charm of the master Rakuju's tsuba. It is published in the Token Kinko Meisaku Shu, edited by Ogura Soemon under the supervision of Akiyama Kyusaku, Honma Junji, and others, published in Showa 11 from the Hosokawa family collection.

Kamiyoshi Rakuju, also recorded as Kanki Rakuju, was the third-generation master of the Kamiyoshi lineage, a branch descending from the celebrated Hayashi Matahachi of Higo Province. The family's founder is said to have been Kamiya Jinzaemon, who entered the service of the Hosokawa house when Hosokawa Tadatoshi took possession of Higo. In the time of Juhei Tadamitsu, the family received the transmitted traditions of the Hayashi house by domain order and devoted itself to reviving the manner of the Kasuga school. The second generation, Juhei Kunihira Fukanobu, was born in Tenmei 6 (1786) and died in Kaei 4 (1851) at the age of sixty-six; his works are characterized by sincerity and outstanding dignity, never resorting to ostentation or novelty for its own sake. Rakuju was Fukanobu's son, born in Bunka 14 (1817) and dying in Meiji 17 (1884) at the age of sixty-eight. Both father and son enjoyed a high reputation as master craftsmen, and several collaborative works by the pair are recorded. That Juhei Tadamitsu is referred to as "the Kamiyoshi grandfather" and Fukanobu as "the Kamiyoshi father" testifies to the great importance of Rakuju's presence within this lineage.
Rakuju's gold inlay was said to demonstrate such technical brilliance that he was called "a second coming of Matahachi," an expression of the highest praise within the Higo tradition. His kinzogan approaches the level of the founding master, displaying a suppleness and vigor that is both delicate and forceful. His forging of the plate metal is also excellent: the well-refined iron exhibits the purplish patina characteristic of Higo tsuba, unctuous in appearance and lustrous, with subtly uneven clusters of texture that impart an elegant charm. He devised and successfully expressed a distinctive surface variation known as gama-hada ("toad-skin"), a special textural effect on the base metal that became one of his hallmarks. The Kamiyoshi family further employed a special uchikomi-tagane (punch-chisel) treatment above and below the nakago-ana — characteristically two marks above and three below — which serves as a decisive identifying feature, enabling attribution of works by both Fukanobu and Rakuju even when unsigned. His openwork encompasses kage-sukashi ("shadow openwork") renderings of butterflies, rain-dragons, auspicious clouds, and warabite (bracken-hand) motifs, all drawn from patterns handed down within the Hayashi school, executed with freely controlled forms that deliberately leave chisel traces to express both refined elegance and strength.
Beyond his accomplishments as a metalworker, the Higo Kinkoroku records that Rakuju's appraisal of metalwork was considered foremost in Higo, and that regarding the construction of sword mountings he attained an especially deep mastery of the inner principles. Beginning with the daimyo's personal mountings and extending throughout the domain household, most refined constructions were produced under his direction. His fully coordinated so-kanagu mountings — including celebrated copies of mountings favored by Miyamoto Musashi — are consonant with the aesthetic of the Hosokawa school of tea, combining pronounced martial character with restrained elegance. Several of his works are transmitted as former possessions of the Hosokawa family. The recurring appearance of the patron name "Ogi Masakuni" inscribed alongside Rakuju's signature on multiple designated works suggests the support of an important commissioning figure, though no other patron's name has been encountered in the same manner. Rakuju stands as a representative figure in late-Edo Higo metalwork, an artisan whose spirited resolve to rival Matahachi yielded works of elevated and refined character.

The Kamiyoshi (神吉) school is the fifth of the celebrated Higo kinko lineages, established in Higo Province under the patronage of the Hosokawa house during the mid-to-late Edo period. According to the NBTHK setsumei, the progenitor of the Kamiyoshi line was Kamiya Jinzaemon[[c:1]], who is said to have become a craftsman when Hosokawa Tadatoshi entered Higo. The school's formal artistic lineage, however, traces directly to Hayashi Matashichi (又七), founder of the Hayashi school. In the time of Juhei Tadamitsu — also known as Masatada (正忠) — the family received by domain order the transmitted traditions (soden) of the Hayashi house and devoted itself to reviving the manner of the Kasuga school (春日派), that is, the Hayashi school. Born in Horeki 4 (1754), Masatada initially studied tsuba making under Zenshichi, a pupil of the second-generation Nishigaki Kanshiro, before entering the school of the third-generation Hayashi Tohachi by official command. He thereafter became an appointed craftsman (kakae-ko) to the Hosokawa family, and from his house emerged the school's two greatest masters: his son, the second-generation Fukanobu (深信, 1786--1851), and his grandson, the third-generation Rakuju (楽寿, 1817--1884). The collective style of the Kamiyoshi school is anchored in the conscious revival of Hayashi-school aesthetics, rendered through a vocabulary of refined iron plate work, controlled openwork, and gold inlay of exceptional sophistication. Their iron plates display the purplish patina (murasabi) characteristic of Higo tsuba — described repeatedly in the setsumei as possessing a viscous, lustrous quality (nettori to shite tsuya ga ari) with subtly uneven surface clusters (jiso) that impart an elegant charm (gashu). The school is distinguished by several signature technical achievements: gama-hada (蟇肌, "toad-skin"), a distinctive surface texture devised and perfected by Rakuju; kareki-zogan (枯木象嵌, "withered-tree" inlay), a gold inlay technique extending from the plate onto the rim; and kuzubishi (葛菱, kudzu-diamond) and uzumaki (渦巻, whirlpool) motifs rendered in gold nunome-zogan. Rakuju's gold inlay was praised across multiple setsumei as approaching the level of the founding master Matashichi himself — the recurring epithet "a second coming of Matashichi" (Matashichi no sairai) appears as a fixed formula in the NBTHK appraisals.
The Kamiyoshi family further employed a distinctive punched-chisel treatment (uchikomi-tagane) above and below the nakago-ana — characteristically two strikes above and three below for Rakuju — enabling attribution of unsigned works by both Fukanobu and Rakuju. Favored design motifs include warabite (蕨手, bracken-hand) openwork, shadow butterflies (kage-cho sukashi), rain-dragons (uryu), auspicious clouds (zuiun), and tomoe forms, all drawn from the Hayashi-school repertoire. Fukanobu's works are consistently characterized as sincere and dignified (seijitsu de hinkaku no sugureta sakufu), never resorting to eccentricity or novelty, while Rakuju brought a more forceful and inventive energy to these inherited forms. The Kamiyoshi school occupies a place of singular importance within the Higo kinko canon as the lineage that most faithfully preserved and reinvigorated the Hayashi tradition into the late Edo period. That Juhei Tadamitsu is referred to as "the Kamiyoshi grandfather" and Juhei Fukanobu as "the Kamiyoshi father" — both epithets defined in relation to Rakuju — testifies to the commanding stature of the third-generation master within this lineage. Fukanobu, though fewer signed works survive, produced pieces of such accomplishment that the NBTHK describes his finest tsuba as the hakubi (白眉, "crowning achievement") among his oeuvre — notably a yatsu-warabite design in imitation of Matashichi with gold sayagata inlay and the Hosokawa kuyo-mon (九曜紋) crest. The father-and-son collaborative works (gassaku) by Fukanobu and Rakuju further demonstrate the school's integrated mastery. Rakuju's late works, produced after decades of striving toward the example of Matashichi, are described as having attained an elevated and refined quality (kosho na sakuhin). Several pieces are recorded as former possessions of the Hosokawa family itself, and the recurrence of the patron name Ogi Masakuni (荻昌国) in commissioned inscriptions attests to the school's intimate relationship with prominent supporters. In the NBTHK's assessment, the finest Kamiyoshi works approach the level of the Hayashi school's founding master — a judgment that secures the school's legacy as the most distinguished heir to the Matashichi tradition.
