At the southern edge of the sword world, in Satsuma, the Naminohira line ran unbroken from the late Heian period into the nineteenth century — among the longest-lived schools of them all. Founded when Masakuni came south from Yamato, its smiths kept the Yamato manner in flowing itame and narrow suguha, marked by yaki-otoshi at the hamachi and a moist, subdued nioiguchi. The early Ko-Naminohira masters around Yukiyasu carry the designations; the long Sue-Naminohira continuation kept the forge alive for five more centuries.

The Satsuma Naminohira School (波平) Lineage
The The Satsuma Naminohira School (波平), active 987–1900 in Satsuma Province across 58 documented smiths: 0 Kokuhō (National Treasures), 3 Jūbun, 2 Jūbi, 3 Tokubetsu Jūyō, 18 Jūyō.
Phase 1 · Ko-Naminohira (古波平) · 987 – 1393
Within the long span of Naminohira, *Ko-Naminohira* (古波平) marks the formative chapter, the body of smiths and works held in the setsumei to not descend past the Nanbokuchō period. The setsumei place the school's base at Naminohira in Taniyama District of Satsuma Province in southern Kyushu, where, by tradition, a Yamato smith named Masakuni settled in the late Heian era around Eien (987 to 989) and founded the line. His son Yukiyasu stands at the head of the working lineage, and the name Yukiyasu passed through generation after generation as the main line (*chakuryū*), with smiths favoring the characters *yuki* (行) and *yasu* (安). The setsumei attach the lineage to the Yamato Senjuin tradition; one Jūyō-Bijutsuhin record fixes the earliest dated inscription in all of Japanese swords to a Heiji 1 (1159) *tachi* read as Yukimasa, recorded in the *meikan* as Ko-Hahei. Beyond Yukiyasu the corpus names Yasuji, Chikayasu, Yasumitsu, Tomoyasu, and Yamauchi Yasuyuki, the named members of this early generation.
The phase style sits close to Yamato yet keeps a Satsuma accent the setsumei return to repeatedly. The forging is *itame* with a flowing *nagare* and *masame* tendency toward the edge, the grain at times standing (*hada-dachi*), carrying well-adhered *ji-nie* and fine *chikei*; the steel is described as *nettori*, a viscous, soft-feeling ground, often with a whitish *shirake-utsuri*. The temper is a narrow *suguha* to *hoso-suguha*, shading at times into *ko-midare* or shallow *notare*, worked in *ko-nie* with frequent *hotsure*, *nijūba*, *yubashiri*, and intermittent *kinsuji* and *sunagashi*. Two diagnostics recur: the *nioiguchi* tends to *urumi*, a moist, subdued quality, and the temper drops away at the base in *yakiootoshi*. The sugata is archaic, slender with deep *koshizori* and *funbari* in the older *tachi*, the *bōshi* commonly *yakizume*. The setsumei frame this against the later Sue-Naminohira only by exclusion: Ko-Naminohira is the early, hand-built work that does not descend beyond Nanbokuchō, set apart from the school's Muromachi disorder and *shintō* decline noted in one record, rather than the routinized later output.
For kantei, the setsumei converge on a recognition cluster: *nettori* ground, *urumi* *nioiguchi*, base *yakiootoshi*, *nijūba* and fine *sunagashi*/*kinsuji* within a *suguha* of strong Yamato cast, an *ayasugi*-like *masame* flavor noted in older works. The records caution that this conservative manner shows little change by period, so a missing *nengō* makes dating difficult and the *ubu* form carries weight. Several setsumei align Ko-Naminohira with other Kyushu classical lines, naming Bungo Yukihira and Miike Mitsuyo as kin in archaic flavor. For provenance and benchmark, the texts cite the *tachi* at Sanage Shrine as Yukiyasu's oldest, the named *tachi* "Sasanuki" transmitted in the Kabayama family of the Shimazu, and a Kareki 2 (1327) dated *tantō*, the rarity of signed and dated early pieces giving the surviving examples their documentary weight.
Yukiyasu (行安) — Mainline · 1308-1311. Jūbun, Jūbi, Tokujū, Jūyō. The oldest Yukiyasu, the published sources record, is the tachi preserved at Sanage Shrine, an Important Cultural Property, and after it comes the tachi called Sasanuki, handed down in the Kabayama family, a branch of the Shimazu house. Yukiyasu is the head name of the Naminohira school of Satsuma. Its founder by tradition is a smith named Masakuni, said to have come from Yamato to Naminohira in Taniyama District in the late Heian period, though no securely attributable work of his survives. His son was Yukiyasu, and the name passed down the main line generation after generation into the shinshinto era. The published sources call the smiths and works no later than the Nanbokucho period Ko-Naminohira, and one entry places Yukiyasu in the stream of the Yamato Senjuin school, a descent it finds borne out by the style of the work.
His manner is close to Yamato, and the published sources name the points that make it Naminohira. The itame flows and turns to a strong masame toward the edge, and the steel carries a viscous, soft feeling the sources call nettori. Over it runs a narrow suguha, finely frayed with hotsure and worked in ko-nie, with yubashiri and nijuba, the nioiguchi clouding in places to urumi. At the base the temper drops away in a yakiotoshi. Of the classical signed tachi raised to Tokubetsu Juyo the sources write that the steel is "viscous, with ji-nie"[[c:1]] and that the temper is "dropped greatly at the base"[[c:2]], and they read the soft steel, the clouded nioiguchi and the dropped base as the points of the school.
The jigane is the steadiest of these marks. Fine ji-nie lies thick on the early tachi, chikei enter, and on another signed tachi the sources note that the steel "has a nettori feeling"[[c:3]]. A whitish shirake-utsuri rises on several blades, and on the later broad works the steel stands a little and turns somewhat dark. The boshi runs straight to a yakizume, or turns in a small round on one face. Activity in the edge varies with the blade. One early tachi, compared with ordinary Ko-Naminohira, shows less urumi and fine sunagashi and kinsuji working well, while a signed tachi of the Nanbokucho period is called "restrained and deeply flavoured in manner"[[c:4]].
His record divides into two forms of the one hand. The first is the slender, classical early-Kamakura tachi, ubu and signed, with a small kissaki, a high and wide shinogi, deep koshizori and funbari, its four-character signature cut with a thick chisel on the upper hira-ji. The second is the broad, powerful work of the late Kamakura to early Nanbokucho period, long and wide with a high wazori. Its finest example is a mumei tachi that first passed Juyo and then Tokubetsu Juyo, its chu-suguha carrying faint streak-like nijuba from base to tip. Beside these stand a fully preserved naginata, which the sources value as one of the school's few surviving examples, and a shortened tachi signed on the haki-ura with the added character zo, a rarity they call valuable as documentary material. Across the span the sources are frank about dating: "as a rule the manner does not change with the age, and this is the point of recognition for this smith and his school"[[c:5]].
The published sources set his traits within a wider Kyushu picture rather than claim them for him alone. The fine nie, the nettori steel, the weak and clouded nioiguchi and the yakiotoshi at the machi give the school an antique fragrance, and the naginata entry notes that this is "shared with the works of other classical Kyushu schools such as Yukihira and Miike Mitsuyo"[[c:6]]. Against Yamato proper he is told by that soft steel and the dropped base. The broad mumei tachi they judge "without flamboyance, yet a savour-rich masterpiece attributed to this smith, showing a dignified presence"[[c:7]], and they hold it the Yukiyasu that represents the school.
For the collector Yukiyasu is a rare early Kyushu name, graded Jo-jo saku by Fujishiro. He has no National Treasures. His record runs through one Important Cultural Property, one prewar Juyo Bijutsuhin, and seven blades in the Tokubetsu Juyo and Juyo tiers, two of which rose to Tokubetsu Juyo: the classical signed tachi and the broad mumei tachi. Of recorded whereabouts, a tachi is held at Sanage Shrine, and the Sasanuki tachi of the Kabayama family ties the name to its home province. The published sources stress that Ko-Naminohira Yukiyasu are few and dated examples rare, so a signed piece comes to light only seldom, and a privately held example with the soft steel and dropped base is a notable thing for a collector to encounter.

Yukimasa (行正) — Mainline · 1159-1160. Jūbi. Yukimasa of Satsuma is known through a single signed tachi dated the second day of the eighth month of Heiji 1 (1159), recognised as a Juyo Bijutsuhin in 1934. The published sources identify him with the Ko-Naminohira smith of the signature compendia: 「この行正は銘鑑に古波平と伝えられているものに該当するであろう」 (this Yukimasa probably corresponds to the one the compendia transmit as Ko-Naminohira). Of the inscription they write 「平治元年紀は現存する日本刀の最古の年紀であり資料的に大変貴重である」 (the Heiji 1 date is the oldest date on any surviving Japanese sword, and of great value as documentary material).
The tachi is long, at two shaku seven sun two bu, and keeps its original tang. The sources describe it as 「生ぶ茎で茎先鍵形ごころとなり腰反り高く踏張り強くついた姿である」 (an *ubu* tang whose tip tends toward a hooked shape, with a high *koshi-zori* and strong *funbari*). The jigane is a tightly packed *ko-itame* mixed with *masame*, with *chikei*, and fine *ji-nie* lying thickly over it. The temper is recorded as 「刃文小沸出来の小乱二重刃ごころあり、砂流しかかる」 (a *ko-midare* in *ko-nie-deki* with a suggestion of *nijuba*, and with *sunagashi*).
On the *haki-omote* the tang also bears the name Kuniyasu, whose meaning the sources leave open, suggesting it may be the name of an owner. The blade is published in the Satsuma To Meisakushu and the Toei Tekiroku. On this one work Yukimasa stands as a late Heian smith of the Naminohira line in Satsuma, his dated tachi combining a deep *koshi-zori* with the *masame*-mixed jigane and *nie*-based *ko-midare* that the sources record. He is distinct from the Bizen smith of the same name.

Phase 2 · Sue-Naminohira (末波平) · 1393 – 1900
Within the long Satsuma lineage that ran from the *kotō* into the *shinshintō* period, Sue-Naminohira (末波平) names the later chapter that carried the Naminohira tradition forward from the close of the Nanbokuchō age through the Muromachi era and into the early Edo workshops of Satsuma and neighbouring Ōsumi. The setsumei place a roster of dated smiths here: *Sadatsugu* of Satsuma and *Haruyuki* around the Tenmon era; *Shigekane* of Ōsumi, signing "Sūshū jū" and said also to have forged in Satsuma, dated Tenbun 14 (1545); *Atsukura*, who unusually prefixed the surname Fujiwara, active through Eiroku, Genki and Tenshō; and *Sadakiyo*, assigned to the Satō line, one of three branches (Hashiguchi, Ishigami, Satō) into which the group divides. The later Yuki-named continuation reaches into the Shintō period with *Yasunetsune*, counted as the fifty-ninth generation, with works dated to Enkyō and Meiwa. Throughout, the smiths worked under the Shimazu of southern Kyushu, geographically removed from the mainland centres.
The setsumei describe a recurring later manner: a forging in which the *hada* stands out and flows with a whitish cast, a low-tempered *suguha* carrying *hotsure*, and a *nioiguchi* that tends toward *urumi*, a moist and soft quality, so that both *ji* and *ha* can read as subdued. This is framed as transmitting the manner of the forebears, the Ko-Naminohira tradition, and as conservative in character, where the early phase is described instead by a fine *hoso-suguha* with *yaki-otoshi* at the *hamachi*. Several pieces here, however, depart from that base by taking up the fashions of their day. The setsumei record works in *Sue-Bizen* style with *koshi-biraki gunome* mixed with pointed and compound elements, and Atsukura's *Sue-Sōshū*-leaning blade with *tobiyaki* approaching a partial *hitatsura*. Given the thin corpus, these are presented as the documented range rather than as fixed traits of the phase.
For kantei, the setsumei separate this phase from Ko-Naminohira by the standing, flowing *hada* and whitish tone paired with the low, *urumi*-tending *suguha*, against which the brighter, *saeru* and strongly *nie*-laden examples are flagged as exceptions worth noting. The *koshi-biraki gunome* with *togariba*, the *katte-sagari* or *higaki* *yasurime*, and the pointed *midare-komi bōshi* with *hakikake* recur as period markers, while *sakizori* and *funbari* register Muromachi *sugata*. Named hands anchor the group: Shigekane and Sadakiyo near Tenmon, Atsukura through Tenshō, and Haruyuki, whose work the setsumei compare to the Bungo Hirataka-Takada school, raising a possible contemporaneous link. The later Yasunetsune line then ties Sue-Naminohira to the Satsuma Shintō idiom, with wide, slightly long proportions and *imo-tsuru* *nie-suji*.
