The Bungo School

Ko-Bungo is the school of Yukihira — the early Kamakura master whose rare signed tachi stand among Kyūshū’s finest, one a Kokuhō — working in a manner that still remembers the ancient smiths: standing hada, yaki-otoshi, a quiet suguha. Around him gathered Chōen and the line that carried the province’s forge into the Muromachi period, centuries before the mass-production era of Bungo Takada.

The Bungo School (豊後) Lineage

The The Bungo School (豊後), active 950–1500 in Bungo Province across 11 documented smiths: 1 Kokuhō (National Treasures), 11 Jūbun, 9 Jūbi, 6 Tokubetsu Jūyō, 24 Jūyō.

Phase 1 · Ko-Bungo (古豊後) · 950 – 1333

Ko-Bungo (古豊後) names the opening chapter of the Bungo school, the work made in the province of Bungo in Kyushu from the close of the Heian period into the Kamakura era, before the school descended into the prolific Takada production of later centuries. Its central figure is Yukihira, signing *Bungo no Kuni Yukihira saku*, whom the setsumei place among the Kyushu *koten-ha* (the Kyushu classical group) as the maker of the highest technical level, with a comparatively large number of surviving works. The phase is rooted in the temple smiths of Mount Hiko (*Hikosan*): tradition makes Yukihira a disciple of the monk Sadahide, whose own signatures (*Bungo no Kuni Sō Sadahide saku*) appear on slender *tachi* of closely related manner, while the sources disagree over whether Sadahide was teacher or pupil. The entries also record Yukihira as one of the *goban-kaji* serving the retired Emperor Go-Toba, the smith Chōen transmitted variously to Buzen, Yamato, or Bungo, and the grandson Chikushi Masatsune, marking out the early Kyushu circle from which the school grew. The style the setsumei describe is archaic and quiet. The *sugata* is slender with high *koshizori* and pronounced *funbari*, a small *ko-kissaki*, and curvature that settles toward the point, a *tachi* form said not to descend beyond the early Kamakura. The *kitae* is *itame* tending to *nagare*, soft and *nettori* (viscous and clinging) in feel, with thick *ji-nie*, *chikei*, and a whitish *shirake* cast or *utsuri* suggestion. The *hamon* runs *suguha* to *ko-midare* with *ko-gunome* and *ko-ashi*, worked in *ko-nie*, the *nioiguchi* repeatedly turning *urumi* (moist and soft); *kinsuji*, *sunagashi*, and *yubashiri* appear, and a *yakiotoshi* drops the temper just above the *machi*, a habit the entries flag as a fingerprint shared with old Kyushu work such as Ko-Hōki and Ko-Naminohira. Carving is distinctive: the Ko-Bungo blades carry *ukibori* *kurikara*, *bonji*, *suken*, Jizō Bosatsu, and the "pine-eating crane" (*matsukui-zuru*), motifs the setsumei state are not seen in works before Yukihira and were later transmitted to Bungo. This restrained, *nie*-laden, carving-rich manner stands apart from the standardized later Bungo Takada output. For *kantei*, the setsumei isolate firm anchors: the soft *nettori* steel with whitish tone, *suguha* or *ko-midare* with *urumi* *nioiguchi*, the base *yakiotoshi*, and the *haura* signature placement Yukihira followed against the convention of his day, a practice the entries link only to Sanjō Munechika and certain Ko-Aoe descendants. The dated *tachi* of Genkyū 2 (1205) fixes the working period. The Kanchi-in text warns that crude *mei* are genuine and skilled ones suspect, since Yukihira "could not write well," and that forgeries arose already in Kamakura. Provenance runs deep: a Yukihira *tachi* identified with the Minamoto treasure "Usugoromo / Usumidori" and bestowed by Tsunayoshi per the *Tokugawa Jikki*, two Imperial Household *gyobutsu* Yukihira *tachi*, and Sadahide blades transmitted through the Mōri and tied to Emperor Go-Mizunoo, with Hon'ami *origami* by Kōon, Kōchū, and Kōon recurring across the group.

Major smiths

Yukihira (行平) — Mainline · 1199-1206. Kokuhō, Jūbun, Jūbi, Tokujū, Jūyō. In the second month of Genkyu 2 (1205), Yukihira of Bungo signed and dated a tachi that still survives; retempered long ago, it is called precious by the published record as the document that fixes his activity at the turn of the Heian and Kamakura periods. He bore the appellation Ki no Shindayu (紀新太夫), worked in Bungo province in Kyushu, and stands at the head of the group the NBTHK calls the Kyushu classical school: his designation texts open with the standing sentence that "within the Kyushu classical school his technique and fame are the highest, and comparatively many of his works survive" (九州古典派の中でも技術と名声が最も高く、現存する作品も比較的多い). Tradition binds him to the monk-smith Joshu, also read Sadahide, of Mount Hiko in the same province, as the monk's pupil by most accounts, his teacher by others, his son by others still. He is also transmitted as one of the goban-kaji of the retired emperor Go-Toba. Even so, the sources note that at first glance his work appears older still. His manner is described as wholly close to Joshu's. The forging is soft and viscous, the nettori steel of the published sources, with a peculiar sheen (一種の色沢があり); the temper is suguha or a small midare, and in either case the nioiguchi clouds softly in urumi; and the habit of dropping the temper above the machi in a yakiotoshi is, the texts add, the same hand in both men (区上で焼き落す手癖も同様). The yakiotoshi is often large, running about half a sun above the machi, and it is fragile evidence: of one greatly shortened katana the sources note plainly that the yakiotoshi has been lost to the shortening itself. His tachi are slender with a small kissaki, the koshizori high and the funbari marked, the curve falling away toward the tip; smallish blades of around two shaku two sun are often met, and a truly large tachi is called exceptional. The jigane is itame, in places flowing and occasionally showing larger grain, with fine, thick ji-nie, delicate chikei and a whitish shirake-utsuri that stands out against the soft steel. Over it the hamon runs as a narrow suguha-cho mixing ko-midare, ko-gunome and a shallow notare, with ko-ashi entering and ko-nie adhering; faint kinsuji and slight sunagashi appear, and small yubashiri drift along the habuchi, in places with a nijuba tendency. The boshi is tempered low and runs sugu into a small ko-maru, at times in the manner of yakizume or with hakikake. One Juyo text gathers the whole into a sentence, "this is a quintessential tachi by Yukihira of Bungo" (豊後の行平の典型的な太刀である): slender and small of kissaki, the jigane a packed ko-itame of viscous character, the hamon a narrow suguha with a little ko-midare and a large yakiotoshi, distinctive carvings at the base, the signature on the haki-ura in artless characters. Two registers carry his name beyond the steel. The first is the chisel. Most of his blades bear small, antique carvings at the koshimoto, foremost a kurikara in relief within a hitsu, with bonji, and at times a Jizo Bosatsu, a pine-eating crane, cherry blossoms or a suken within the groove; the published sources state that "carving of this kind is not seen in works before his" (この種の彫刻は彼以前の作には見当らない), and the imperial-collection texts add that the method was handed on to later Bungo work. A blade wholly without carvings is the rarity; of one such tachi, once held by Tokugawa Iesato, Honma Junji wrote that its workmanship nevertheless ranks among the most outstanding in the oeuvre. The second register is the mei. He cuts a long signature, Bungo no kuni Yukihira saku (豊後国行平作), on the haki-ura toward the mune, the reverse of the general practice of his day; ordinary tachi-mei pieces survive, but only a few. The characters are scratched and artless, and in that clumsiness lies his individuality, for the Showa Meizukushi (正和銘尽), the oldest of the sword books, already records that forgeries of Yukihira abounded in the Kamakura period and teaches that skillfully written characters are all false signatures (銘字の巧みなものは皆偽銘). His rare forms belong here too: a signed ken called notably well made; tanto, exceptionally rare for his period; and a kodachi, few in his work, recorded in the Kozan Oshigata. Not all of these marks are his alone. The soft steel, the urumi of the nioiguchi and the yakiotoshi are named by the published sources as features common to the old work of Kyushu at large, Ko-Naminohira among them, and the imperial-collection texts trace that company to the classical style of the Shosoin treasures, faithfully transmitted. What sets Yukihira at its head is the union of the school features with his own: the nettori itame under shirake-utsuri, the quiet suguha-cho with its small midare, the carvings at the koshimoto, and the long mei on the haki-ura. His fame is itself ancient, secure since the Kamakura period, when the sword books already had to warn against his forgers; his koshimoto carvings stand at the beginning of sword horimono and anticipate the carving smiths of later centuries; and the Bungo tradition descends from his school. Fujishiro rates him Sai-jo saku, and thirty-seven designated works stand on record, thirty-three of them signed. Two signed tachi are handed down as gyobutsu in the imperial collection; ten blades are Important Cultural Properties; five are prewar Juyo Bijutsuhin, among them the Genkyu-dated tachi once owned by Kujo Michihide and a tanto formerly of Uesugi Kensho; and five blades hold the Tokubetsu Juyo rank and fifteen the Juyo, twenty in the two tiers together. His blades passed in the Tokugawa shogun family and in the Mito and Kishu Tokugawa houses, and two tachi carry origami of Hon'ami Koon dated Kanbun 1 (1661). Even unsigned he is scarce: only four mumei works stand among the designations, one a greatly shortened katana bearing the suriage-mei Yukihira agaru (行平上ル), another the tachi of the Kishu Tokugawa family. The imperial and Cultural Property pieces are patrimony, resting in the imperial collection, in shrines and in long-held collections; what a collector may realistically encounter is the Tokubetsu Juyo and Juyo tier, twenty blades, most of them signed tachi of the classic manner. Such a blade comes to market only rarely, and the old caution of the Meizukushi keeps the question of the mei alive after seven centuries; when a tachi with the scratched, artless long signature on the haki-ura does appear, the yakiotoshi intact above the machi, it carries a signature cut at the very dawn of the Kamakura period in the smith's own hand.
Sadahide (定秀) — Mainline · 1160-1161. Jūbi, Jūyō. Sadahide worked in Bungo Province at the turn of the Heian and Kamakura periods, and the published sources record him as a monk of Mount Hiko, the old religious mountain of Kyushu. They place him at the root of the Bungo tradition beside its founding figure, Yukihira, though they cannot settle which of the two came first: "Sadahide was a monk of Hikosan, said to be either the teacher or the disciple of Yukihira" (定秀は彦山の僧で行平の師とも弟子ともいう). No dated blade survives to fix him in time. What survives instead is a small group of signed tachi inscribed Bungo no kuni so Sadahide, and the form of those blades does the dating: slender, with a high koshi-zori and clear funbari, the point sinking a little to a ko-kissaki, an archaic and elegant shape that, in the words of the 70th Juyo commentary, does not descend below the early Kamakura. His hand is read first in the calm of the temper. Over the whole of his signed work runs a narrow suguha carrying a shallow notare, into which he mixes a quiet ko-midare rather than the showy clove-flower of contemporary Bizen. The tell of that edge is its nioiguchi, which the published sources describe again and again as softly clouded, urumi, never bright and clear; the Hon'ami appraisal of his tanto puts it that the temper is suguha-toned with small irregularities, the nioiguchi "moist and softened" (匂口がうるんで). Thick ko-nie gathers along it, and uchinoke-like crescents, a faint nijuba, fine kinsuji and sunagashi work through the edge without ever crowding it. The boshi runs straight to a yakizume on one face and turns in a small ko-maru on the other, often with hakikake. It is, as the commentary on the signed ko-tachi has it, the "gentle, restrained charm of a Kyushu work" (九州物らしい穏やかな魅力). The jigane carries the same archaic register. He forges an itame that flows toward masame and stands a little, well refined in the manner the sources liken to Yukihira's own, with ji-nie adhering and fine chikei entering. Over it the steel takes a whitish, shirake cast rather than the bright midare-utsuri of Bizen; the prewar Juyo Bijutsuhin tachi note only an utsuri-like effect on the same ji. Taken together, the flowing whitish ji and the nie-laden, clouded suguha are exactly what the 70th Juyo entry calls the "characteristic ji and ha of the Kyushu classical group" (九州古典派の地刃の特徴が表れている), and they are the surest way his work is told from the brighter classical hands of Bizen and Yamashiro. There are two faces to his record. The first is the signed tachi and ko-tachi just described, the recognized prime of his hand. The second is the mumei tanto in hira-zukuri with mitsu-mune that Hon'ami Mitsutsune appraised as Sadahide in 1678, issuing a thirty-sheet origami and cutting the name in vermilion. On that blade the jigane is in nothing different from his usual, but the hamon turns especially exuberantly midare in the upper half, an effect, the commentary states plainly, "not seen in Yukihira" (行平には見られない出来である). The omote carries a raised-relief Kurikara and the ura a bonji, carvings of a kind also found on Yukihira. Mitsutsune judged the blade an early Bungo work and, precisely because it showed a workmanship Yukihira does not, named it Sadahide, a judgment the published sources call admirable. What sets Sadahide apart within his own circle is named in the sources themselves. He is held close to Yukihira in his itame and his nie-laden suguha, yet distinguished from him by that upper-blade midare and by the scale and manner of his signature, which the judges admit is itself unsettled: "the signatures of Sadahide seen to date are not uniform, and there is room for study as to which should be taken as typical" (経眼した定秀の銘振りは一律ではなく). One tachi cuts the character katsu together with cherry blossoms, a motif also seen on Yukihira, while a carved katsu is otherwise known on Ohara Sanemori of old Hoki, so the connoisseurship places him squarely among the classical hands of the western provinces. He stands before the flowering of Bungo into its later, more numerous schools, one of the quiet early roots of swordmaking on the southern island. For the collector he is a rare and early name. Fujishiro grades him Jo-jo saku. He has no National Treasures and no Important Cultural Properties on record; his standing rests instead on the prewar Juyo Bijutsuhin designations of three signed tachi and on two modern Juyo blades, the signed ko-tachi of the 70th session and the Hon'ami-appraised tanto of the 12th. The published commentary makes the point that, signed Sadahide being so few, "the very signature of Sadahide, of which in-mei examples are extremely scarce, is exceptionally valuable" (在銘品が極めて少ない定秀の銘字も非常に貴重). His blades are documents as much as swords. One of the Juyo Bijutsuhin tachi is transmitted as a piece "received by Mori Hidechika, the first Mori lord, from Emperor Go-Mizunoo" (毛利家初代秀就が後水尾天皇より拝領したものと伝える), and the Mori house and the Tokyo collector Takenaka Jiro appear among his recorded owners; of present whereabouts the record names the Kyushu National Museum, Iyo Inari Jinja and Itsukushima Jinja. A signed Sadahide comes to light only seldom, and a privately held example would be among the rarer things a collector of early Kyushu work could hope to encounter, valued less for availability than for the document it carries of how the Bungo tradition began.
Masatsune (正恒) — Mainline · 1199-1201. Jūbi. Smith of the Bungo School.
Choen (長圓) — Mainline · 987-989. Tokujū. Smith of the Bungo School.
Choen (長圓) — Mainline · 1213-1219. Jūyō. Choen was a swordsmith of Buzen Province, traditionally said to have been active around the Eien era (987-989). According to the *meikan*, several smiths bearing this name are known across succeeding generations, and those using a two-character signature are associated with the Genryaku era (1184-1185). There is also a tradition identifying Choen as a Yamato smith. Signed works are extremely few, making attribution a matter of careful stylistic appraisal rather than documentary certainty. The characteristics attributed to Choen's work include a conspicuously sticky, *nettori* quality in the *jigane*, with fine *ji-nie* adhering closely. The forging is a well-compacted *ko-itame* with areas tending toward *masame*, producing an attractive, somewhat whitish cast overall. The *hamon* ranges from fine *suguha* to *chu-suguha* with *gunome*, and within it places showing an *urumi* (moist, soft) tendency appear -- features that, as the NBTHK notes, "well express the characteristics of Kyushu work." The presence of *ko-nie*, *kinsuji*, and *sunagashi* further enriches the temper. These qualities strongly call to mind works such as those of Bungo Yukihira, and the period of the oldest surviving example should not descend later than Yukihira's own time. Blades attributed to Choen display an archaic *sugata* with slender proportions, *ko-kissaki*, and deep *koshi-zori*, in which "both *ji* and *ha* are outstanding." One blade preserves an *orikaeshi-mei* in bold, thick chisel-work -- the oldest surviving signed example known today. A further notable tradition holds that the ancient treasure sword of the Minamoto clan, the *tachi* called Usumidori ("Pale Green"), is in fact this very blade. Even where attribution to Choen cannot be confirmed with certainty, as with a tanto bearing a Kenpo 1 (1213) date inscription, the workmanship and inscriptions remain valuable.
Munechika (宗近) — Mainline · 999-1004. Jūyō. Smith of the Bungo School.

Phase 2 · Bungo (豊後) · 1333 – 1500

Where the early Ko-Bungo of Yukihira represents the province's *koto* opening, the later Bungo phase covers the smiths who carried sword production in the province through the Nanbokuchō and Muromachi centuries, by which time the work had reorganized around the Takada lineage and its allied groups in Kyūshū. The setsumei name Tomoyuki of Bungo, who signed "Hōshū Fujiwara Tomoyuki" and is treated as a representative figure of the Nanbokuchō Bungo smiths; Sadayuki, placed in the Takada school and transmitted as the son of Tomoyuki; and Norisada of Kutsunami-gō in Naoiri District, working around the Hōtoku era. The Takada body itself is subdivided in these notes, with a *Hira-Takada* group named, and the Kutsunami smiths of Naoiri are recorded as a small, poorly documented offshoot. Bungo sits within a wider Kyūshū sphere, and the setsumei repeatedly read these blades against that regional context rather than against Yukihira's earlier output. The traits recorded for this phase are quieter and more workmanlike than the refined horimono associated with Ko-Bungo Yukihira. Tomoyuki's *tantō* show *itame-hada* with flowing, standing grain, *sō-gunome* mixed with *ko-notare*, a subdued (*shizumi*) *nioiguchi*, *sunagashi*, and *bōhi* carved *kaki-nagashi*; one setsumei calls his manner Yamato-like, "a manner shared broadly by Kyūshū works," while noting a separate resemblance to Sa Yasuyoshi of Chikuzen and to the Enbun-era Kanemitsu line of Osafune. Sadayuki's Takada *katana* runs to *ko-notare* mixed with *ko-chōji*, *ko-gunome*, and small *midare*, with a *shirake* tendency in the *ji* and a tightening *nioiguchi*. Norisada's blade is *chū-suguha* with mixed small *gunome*, faint *utsuri*, and a *nioiguchi* tending toward *urumi*, described as a subdued (*jimi*) *dekiguchi*. The horimono here is functional *bōhi* rather than the carving that distinguishes the early phase. For *kantei*, the distinguishing features the setsumei supply are the *suguha*-and-*gunome* or *ko-notare* hamon, the *shirake* or *urumi* tendencies in *ji* and *nioiguchi*, and the Yamato-tinged, regionally shared manner, all of which separate the later Bungo from Yukihira's earlier work. The notes also caution against confusion within the phase itself: a second Sadayuki line of the Nanbokuchō period signs in *tachi-mei* with a differing calligraphic form and must not be read as the Takada Sadayuki. Provenance is documentary rather than illustrious. Norisada's dated Hōtoku 3 blade is published in the *Kōzan Oshigata* and is valued for research into the Kutsunami smiths, while Tomoyuki's *Sadaji*-dated *tantō* are cited as scarce surviving signed and dated examples of the line.

Yukihira (行平) — Mainline · 1199-1206. Kokuhō, Jūbun, Jūbi, Tokujū, Jūyō. In the second month of Genkyu 2 (1205), Yukihira of Bungo signed and dated a tachi that still survives; retempered long ago, it is called precious by the published record as the document that fixes his activity at the turn of the Heian and Kamakura periods. He bore the appellation Ki no Shindayu (紀新太夫), worked in Bungo province in Kyushu, and stands at the head of the group the NBTHK calls the Kyushu classical school: his designation texts open with the standing sentence that "within the Kyushu classical school his technique and fame are the highest, and comparatively many of his works survive" (九州古典派の中でも技術と名声が最も高く、現存する作品も比較的多い). Tradition binds him to the monk-smith Joshu, also read Sadahide, of Mount Hiko in the same province, as the monk's pupil by most accounts, his teacher by others, his son by others still. He is also transmitted as one of the goban-kaji of the retired emperor Go-Toba. Even so, the sources note that at first glance his work appears older still. His manner is described as wholly close to Joshu's. The forging is soft and viscous, the nettori steel of the published sources, with a peculiar sheen (一種の色沢があり); the temper is suguha or a small midare, and in either case the nioiguchi clouds softly in urumi; and the habit of dropping the temper above the machi in a yakiotoshi is, the texts add, the same hand in both men (区上で焼き落す手癖も同様). The yakiotoshi is often large, running about half a sun above the machi, and it is fragile evidence: of one greatly shortened katana the sources note plainly that the yakiotoshi has been lost to the shortening itself. His tachi are slender with a small kissaki, the koshizori high and the funbari marked, the curve falling away toward the tip; smallish blades of around two shaku two sun are often met, and a truly large tachi is called exceptional. The jigane is itame, in places flowing and occasionally showing larger grain, with fine, thick ji-nie, delicate chikei and a whitish shirake-utsuri that stands out against the soft steel. Over it the hamon runs as a narrow suguha-cho mixing ko-midare, ko-gunome and a shallow notare, with ko-ashi entering and ko-nie adhering; faint kinsuji and slight sunagashi appear, and small yubashiri drift along the habuchi, in places with a nijuba tendency. The boshi is tempered low and runs sugu into a small ko-maru, at times in the manner of yakizume or with hakikake. One Juyo text gathers the whole into a sentence, "this is a quintessential tachi by Yukihira of Bungo" (豊後の行平の典型的な太刀である): slender and small of kissaki, the jigane a packed ko-itame of viscous character, the hamon a narrow suguha with a little ko-midare and a large yakiotoshi, distinctive carvings at the base, the signature on the haki-ura in artless characters. Two registers carry his name beyond the steel. The first is the chisel. Most of his blades bear small, antique carvings at the koshimoto, foremost a kurikara in relief within a hitsu, with bonji, and at times a Jizo Bosatsu, a pine-eating crane, cherry blossoms or a suken within the groove; the published sources state that "carving of this kind is not seen in works before his" (この種の彫刻は彼以前の作には見当らない), and the imperial-collection texts add that the method was handed on to later Bungo work. A blade wholly without carvings is the rarity; of one such tachi, once held by Tokugawa Iesato, Honma Junji wrote that its workmanship nevertheless ranks among the most outstanding in the oeuvre. The second register is the mei. He cuts a long signature, Bungo no kuni Yukihira saku (豊後国行平作), on the haki-ura toward the mune, the reverse of the general practice of his day; ordinary tachi-mei pieces survive, but only a few. The characters are scratched and artless, and in that clumsiness lies his individuality, for the Showa Meizukushi (正和銘尽), the oldest of the sword books, already records that forgeries of Yukihira abounded in the Kamakura period and teaches that skillfully written characters are all false signatures (銘字の巧みなものは皆偽銘). His rare forms belong here too: a signed ken called notably well made; tanto, exceptionally rare for his period; and a kodachi, few in his work, recorded in the Kozan Oshigata. Not all of these marks are his alone. The soft steel, the urumi of the nioiguchi and the yakiotoshi are named by the published sources as features common to the old work of Kyushu at large, Ko-Naminohira among them, and the imperial-collection texts trace that company to the classical style of the Shosoin treasures, faithfully transmitted. What sets Yukihira at its head is the union of the school features with his own: the nettori itame under shirake-utsuri, the quiet suguha-cho with its small midare, the carvings at the koshimoto, and the long mei on the haki-ura. His fame is itself ancient, secure since the Kamakura period, when the sword books already had to warn against his forgers; his koshimoto carvings stand at the beginning of sword horimono and anticipate the carving smiths of later centuries; and the Bungo tradition descends from his school. Fujishiro rates him Sai-jo saku, and thirty-seven designated works stand on record, thirty-three of them signed. Two signed tachi are handed down as gyobutsu in the imperial collection; ten blades are Important Cultural Properties; five are prewar Juyo Bijutsuhin, among them the Genkyu-dated tachi once owned by Kujo Michihide and a tanto formerly of Uesugi Kensho; and five blades hold the Tokubetsu Juyo rank and fifteen the Juyo, twenty in the two tiers together. His blades passed in the Tokugawa shogun family and in the Mito and Kishu Tokugawa houses, and two tachi carry origami of Hon'ami Koon dated Kanbun 1 (1661). Even unsigned he is scarce: only four mumei works stand among the designations, one a greatly shortened katana bearing the suriage-mei Yukihira agaru (行平上ル), another the tachi of the Kishu Tokugawa family. The imperial and Cultural Property pieces are patrimony, resting in the imperial collection, in shrines and in long-held collections; what a collector may realistically encounter is the Tokubetsu Juyo and Juyo tier, twenty blades, most of them signed tachi of the classic manner. Such a blade comes to market only rarely, and the old caution of the Meizukushi keeps the question of the mei alive after seven centuries; when a tachi with the scratched, artless long signature on the haki-ura does appear, the yakiotoshi intact above the machi, it carries a signature cut at the very dawn of the Kamakura period in the smith's own hand.
Sadahide (定秀) — Mainline · 1160-1161. Jūbi, Jūyō. Sadahide worked in Bungo Province at the turn of the Heian and Kamakura periods, and the published sources record him as a monk of Mount Hiko, the old religious mountain of Kyushu. They place him at the root of the Bungo tradition beside its founding figure, Yukihira, though they cannot settle which of the two came first: "Sadahide was a monk of Hikosan, said to be either the teacher or the disciple of Yukihira" (定秀は彦山の僧で行平の師とも弟子ともいう). No dated blade survives to fix him in time. What survives instead is a small group of signed tachi inscribed Bungo no kuni so Sadahide, and the form of those blades does the dating: slender, with a high koshi-zori and clear funbari, the point sinking a little to a ko-kissaki, an archaic and elegant shape that, in the words of the 70th Juyo commentary, does not descend below the early Kamakura. His hand is read first in the calm of the temper. Over the whole of his signed work runs a narrow suguha carrying a shallow notare, into which he mixes a quiet ko-midare rather than the showy clove-flower of contemporary Bizen. The tell of that edge is its nioiguchi, which the published sources describe again and again as softly clouded, urumi, never bright and clear; the Hon'ami appraisal of his tanto puts it that the temper is suguha-toned with small irregularities, the nioiguchi "moist and softened" (匂口がうるんで). Thick ko-nie gathers along it, and uchinoke-like crescents, a faint nijuba, fine kinsuji and sunagashi work through the edge without ever crowding it. The boshi runs straight to a yakizume on one face and turns in a small ko-maru on the other, often with hakikake. It is, as the commentary on the signed ko-tachi has it, the "gentle, restrained charm of a Kyushu work" (九州物らしい穏やかな魅力). The jigane carries the same archaic register. He forges an itame that flows toward masame and stands a little, well refined in the manner the sources liken to Yukihira's own, with ji-nie adhering and fine chikei entering. Over it the steel takes a whitish, shirake cast rather than the bright midare-utsuri of Bizen; the prewar Juyo Bijutsuhin tachi note only an utsuri-like effect on the same ji. Taken together, the flowing whitish ji and the nie-laden, clouded suguha are exactly what the 70th Juyo entry calls the "characteristic ji and ha of the Kyushu classical group" (九州古典派の地刃の特徴が表れている), and they are the surest way his work is told from the brighter classical hands of Bizen and Yamashiro. There are two faces to his record. The first is the signed tachi and ko-tachi just described, the recognized prime of his hand. The second is the mumei tanto in hira-zukuri with mitsu-mune that Hon'ami Mitsutsune appraised as Sadahide in 1678, issuing a thirty-sheet origami and cutting the name in vermilion. On that blade the jigane is in nothing different from his usual, but the hamon turns especially exuberantly midare in the upper half, an effect, the commentary states plainly, "not seen in Yukihira" (行平には見られない出来である). The omote carries a raised-relief Kurikara and the ura a bonji, carvings of a kind also found on Yukihira. Mitsutsune judged the blade an early Bungo work and, precisely because it showed a workmanship Yukihira does not, named it Sadahide, a judgment the published sources call admirable. What sets Sadahide apart within his own circle is named in the sources themselves. He is held close to Yukihira in his itame and his nie-laden suguha, yet distinguished from him by that upper-blade midare and by the scale and manner of his signature, which the judges admit is itself unsettled: "the signatures of Sadahide seen to date are not uniform, and there is room for study as to which should be taken as typical" (経眼した定秀の銘振りは一律ではなく). One tachi cuts the character katsu together with cherry blossoms, a motif also seen on Yukihira, while a carved katsu is otherwise known on Ohara Sanemori of old Hoki, so the connoisseurship places him squarely among the classical hands of the western provinces. He stands before the flowering of Bungo into its later, more numerous schools, one of the quiet early roots of swordmaking on the southern island. For the collector he is a rare and early name. Fujishiro grades him Jo-jo saku. He has no National Treasures and no Important Cultural Properties on record; his standing rests instead on the prewar Juyo Bijutsuhin designations of three signed tachi and on two modern Juyo blades, the signed ko-tachi of the 70th session and the Hon'ami-appraised tanto of the 12th. The published commentary makes the point that, signed Sadahide being so few, "the very signature of Sadahide, of which in-mei examples are extremely scarce, is exceptionally valuable" (在銘品が極めて少ない定秀の銘字も非常に貴重). His blades are documents as much as swords. One of the Juyo Bijutsuhin tachi is transmitted as a piece "received by Mori Hidechika, the first Mori lord, from Emperor Go-Mizunoo" (毛利家初代秀就が後水尾天皇より拝領したものと伝える), and the Mori house and the Tokyo collector Takenaka Jiro appear among his recorded owners; of present whereabouts the record names the Kyushu National Museum, Iyo Inari Jinja and Itsukushima Jinja. A signed Sadahide comes to light only seldom, and a privately held example would be among the rarer things a collector of early Kyushu work could hope to encounter, valued less for availability than for the document it carries of how the Bungo tradition began.

Choen (長圓) — Mainline · 987-989. Tokujū. Smith of the Bungo School.
Choen (長圓) — Mainline · 1213-1219. Jūyō. Choen was a swordsmith of Buzen Province, traditionally said to have been active around the Eien era (987-989). According to the *meikan*, several smiths bearing this name are known across succeeding generations, and those using a two-character signature are associated with the Genryaku era (1184-1185). There is also a tradition identifying Choen as a Yamato smith. Signed works are extremely few, making attribution a matter of careful stylistic appraisal rather than documentary certainty. The characteristics attributed to Choen's work include a conspicuously sticky, *nettori* quality in the *jigane*, with fine *ji-nie* adhering closely. The forging is a well-compacted *ko-itame* with areas tending toward *masame*, producing an attractive, somewhat whitish cast overall. The *hamon* ranges from fine *suguha* to *chu-suguha* with *gunome*, and within it places showing an *urumi* (moist, soft) tendency appear -- features that, as the NBTHK notes, "well express the characteristics of Kyushu work." The presence of *ko-nie*, *kinsuji*, and *sunagashi* further enriches the temper. These qualities strongly call to mind works such as those of Bungo Yukihira, and the period of the oldest surviving example should not descend later than Yukihira's own time. Blades attributed to Choen display an archaic *sugata* with slender proportions, *ko-kissaki*, and deep *koshi-zori*, in which "both *ji* and *ha* are outstanding." One blade preserves an *orikaeshi-mei* in bold, thick chisel-work -- the oldest surviving signed example known today. A further notable tradition holds that the ancient treasure sword of the Minamoto clan, the *tachi* called Usumidori ("Pale Green"), is in fact this very blade. Even where attribution to Choen cannot be confirmed with certainty, as with a tanto bearing a Kenpo 1 (1213) date inscription, the workmanship and inscriptions remain valuable.

Yukihira (行平) — Mainline · 1199-1206. Kokuhō, Jūbun, Jūbi, Tokujū, Jūyō. In the second month of Genkyu 2 (1205), Yukihira of Bungo signed and dated a tachi that still survives; retempered long ago, it is called precious by the published record as the document that fixes his activity at the turn of the Heian and Kamakura periods. He bore the appellation Ki no Shindayu (紀新太夫), worked in Bungo province in Kyushu, and stands at the head of the group the NBTHK calls the Kyushu classical school: his designation texts open with the standing sentence that "within the Kyushu classical school his technique and fame are the highest, and comparatively many of his works survive" (九州古典派の中でも技術と名声が最も高く、現存する作品も比較的多い). Tradition binds him to the monk-smith Joshu, also read Sadahide, of Mount Hiko in the same province, as the monk's pupil by most accounts, his teacher by others, his son by others still. He is also transmitted as one of the goban-kaji of the retired emperor Go-Toba. Even so, the sources note that at first glance his work appears older still. His manner is described as wholly close to Joshu's. The forging is soft and viscous, the nettori steel of the published sources, with a peculiar sheen (一種の色沢があり); the temper is suguha or a small midare, and in either case the nioiguchi clouds softly in urumi; and the habit of dropping the temper above the machi in a yakiotoshi is, the texts add, the same hand in both men (区上で焼き落す手癖も同様). The yakiotoshi is often large, running about half a sun above the machi, and it is fragile evidence: of one greatly shortened katana the sources note plainly that the yakiotoshi has been lost to the shortening itself. His tachi are slender with a small kissaki, the koshizori high and the funbari marked, the curve falling away toward the tip; smallish blades of around two shaku two sun are often met, and a truly large tachi is called exceptional. The jigane is itame, in places flowing and occasionally showing larger grain, with fine, thick ji-nie, delicate chikei and a whitish shirake-utsuri that stands out against the soft steel. Over it the hamon runs as a narrow suguha-cho mixing ko-midare, ko-gunome and a shallow notare, with ko-ashi entering and ko-nie adhering; faint kinsuji and slight sunagashi appear, and small yubashiri drift along the habuchi, in places with a nijuba tendency. The boshi is tempered low and runs sugu into a small ko-maru, at times in the manner of yakizume or with hakikake. One Juyo text gathers the whole into a sentence, "this is a quintessential tachi by Yukihira of Bungo" (豊後の行平の典型的な太刀である): slender and small of kissaki, the jigane a packed ko-itame of viscous character, the hamon a narrow suguha with a little ko-midare and a large yakiotoshi, distinctive carvings at the base, the signature on the haki-ura in artless characters. Two registers carry his name beyond the steel. The first is the chisel. Most of his blades bear small, antique carvings at the koshimoto, foremost a kurikara in relief within a hitsu, with bonji, and at times a Jizo Bosatsu, a pine-eating crane, cherry blossoms or a suken within the groove; the published sources state that "carving of this kind is not seen in works before his" (この種の彫刻は彼以前の作には見当らない), and the imperial-collection texts add that the method was handed on to later Bungo work. A blade wholly without carvings is the rarity; of one such tachi, once held by Tokugawa Iesato, Honma Junji wrote that its workmanship nevertheless ranks among the most outstanding in the oeuvre. The second register is the mei. He cuts a long signature, Bungo no kuni Yukihira saku (豊後国行平作), on the haki-ura toward the mune, the reverse of the general practice of his day; ordinary tachi-mei pieces survive, but only a few. The characters are scratched and artless, and in that clumsiness lies his individuality, for the Showa Meizukushi (正和銘尽), the oldest of the sword books, already records that forgeries of Yukihira abounded in the Kamakura period and teaches that skillfully written characters are all false signatures (銘字の巧みなものは皆偽銘). His rare forms belong here too: a signed ken called notably well made; tanto, exceptionally rare for his period; and a kodachi, few in his work, recorded in the Kozan Oshigata. Not all of these marks are his alone. The soft steel, the urumi of the nioiguchi and the yakiotoshi are named by the published sources as features common to the old work of Kyushu at large, Ko-Naminohira among them, and the imperial-collection texts trace that company to the classical style of the Shosoin treasures, faithfully transmitted. What sets Yukihira at its head is the union of the school features with his own: the nettori itame under shirake-utsuri, the quiet suguha-cho with its small midare, the carvings at the koshimoto, and the long mei on the haki-ura. His fame is itself ancient, secure since the Kamakura period, when the sword books already had to warn against his forgers; his koshimoto carvings stand at the beginning of sword horimono and anticipate the carving smiths of later centuries; and the Bungo tradition descends from his school. Fujishiro rates him Sai-jo saku, and thirty-seven designated works stand on record, thirty-three of them signed. Two signed tachi are handed down as gyobutsu in the imperial collection; ten blades are Important Cultural Properties; five are prewar Juyo Bijutsuhin, among them the Genkyu-dated tachi once owned by Kujo Michihide and a tanto formerly of Uesugi Kensho; and five blades hold the Tokubetsu Juyo rank and fifteen the Juyo, twenty in the two tiers together. His blades passed in the Tokugawa shogun family and in the Mito and Kishu Tokugawa houses, and two tachi carry origami of Hon'ami Koon dated Kanbun 1 (1661). Even unsigned he is scarce: only four mumei works stand among the designations, one a greatly shortened katana bearing the suriage-mei Yukihira agaru (行平上ル), another the tachi of the Kishu Tokugawa family. The imperial and Cultural Property pieces are patrimony, resting in the imperial collection, in shrines and in long-held collections; what a collector may realistically encounter is the Tokubetsu Juyo and Juyo tier, twenty blades, most of them signed tachi of the classic manner. Such a blade comes to market only rarely, and the old caution of the Meizukushi keeps the question of the mei alive after seven centuries; when a tachi with the scratched, artless long signature on the haki-ura does appear, the yakiotoshi intact above the machi, it carries a signature cut at the very dawn of the Kamakura period in the smith's own hand.
Sadahide (定秀) — Mainline · 1160-1161. Jūbi, Jūyō. Sadahide worked in Bungo Province at the turn of the Heian and Kamakura periods, and the published sources record him as a monk of Mount Hiko, the old religious mountain of Kyushu. They place him at the root of the Bungo tradition beside its founding figure, Yukihira, though they cannot settle which of the two came first: "Sadahide was a monk of Hikosan, said to be either the teacher or the disciple of Yukihira" (定秀は彦山の僧で行平の師とも弟子ともいう). No dated blade survives to fix him in time. What survives instead is a small group of signed tachi inscribed Bungo no kuni so Sadahide, and the form of those blades does the dating: slender, with a high koshi-zori and clear funbari, the point sinking a little to a ko-kissaki, an archaic and elegant shape that, in the words of the 70th Juyo commentary, does not descend below the early Kamakura. His hand is read first in the calm of the temper. Over the whole of his signed work runs a narrow suguha carrying a shallow notare, into which he mixes a quiet ko-midare rather than the showy clove-flower of contemporary Bizen. The tell of that edge is its nioiguchi, which the published sources describe again and again as softly clouded, urumi, never bright and clear; the Hon'ami appraisal of his tanto puts it that the temper is suguha-toned with small irregularities, the nioiguchi "moist and softened" (匂口がうるんで). Thick ko-nie gathers along it, and uchinoke-like crescents, a faint nijuba, fine kinsuji and sunagashi work through the edge without ever crowding it. The boshi runs straight to a yakizume on one face and turns in a small ko-maru on the other, often with hakikake. It is, as the commentary on the signed ko-tachi has it, the "gentle, restrained charm of a Kyushu work" (九州物らしい穏やかな魅力). The jigane carries the same archaic register. He forges an itame that flows toward masame and stands a little, well refined in the manner the sources liken to Yukihira's own, with ji-nie adhering and fine chikei entering.
