The sword-town of the Tōkaidō. At Shimada in Suruga, the Yoshisuke and Sukemune lines headed a Sōshū-current school that armed the Imagawa, Takeda and Hōjō through the Sengoku century — best remembered for powerful tantō, made for warlords who knew exactly what a blade was for.

The Suruga Shimada School (島田) Lineage
The The Suruga Shimada School (島田), active 1430–1600 in Suruga Province across 9 documented smiths: 0 Kokuhō (National Treasures), 0 Jūbun, 1 Jūbi, 0 Tokubetsu Jūyō, 30 Jūyō.
Phase 1 · The Suruga Shimada School (島田) · 1430 – 1600
Hirosuke (廣助) — Mainline · 1504-1521. Jūbi, Jūyō. Hirosuke (広助) worked at Shimada in Suruga in the late Muromachi period, and his surest date is a katana he forged away from home: signed Shimada Hirosuke made this in Koshu[[c:1]], dated the second month of Eiroku 2 (1559), it carries the owner inscription of Hara Mino Nyudo, the Toratane counted among the twenty-four generals of the Takeda. The published sources set the Shimada school out from its own genealogy. Yoshisuke, who took the Buddhist name Keizen, worked around Kosho, with his younger brother Sukemune; both names ran through several generations, and Hirosuke appears among the pupils of the third Yoshisuke. The sword directories cited in his Juyo papers make him the son of the second Yoshisuke, active around Eisho, with a second generation around Tensho and later bearers of the name reaching the shinto period.
His generations are a question the published record leaves open. Two texts state that Hirosuke was a single generation only, while others count several smiths of the name, and one Juyo paper holds that the signature style of its katana is the oldest of them, around Tenbun. Another judges by the form of the mei that its blade belongs between Eiroku and the first years of Tensho. Yoshisuke, Sukemune and Hirosuke are named together as the representative smiths of the school, and the three of them are recorded working in Koshu from Eiroku into the beginning of Tensho.
Within that trio the sources give Hirosuke the boldest hand. They write that among the three "Hirosuke shows the most robust manner and has spirit"[[c:2]], and that he generally excelled in wide, imposing work[[c:3]]. His katana are wide in mihaba, often thick in kasane, with a marked sakizori and a chu-kissaki that extends or opens into an o-kissaki. The jigane is itame with ji-nie, at times mixed with mokume or o-hada and flowing in places, and in several works the steel has a slightly whitish cast; one katana shows a tight ko-itame instead.
The hamon is built on a ko-notare or notare tone mixed with gunome and a choji feeling, with angular and pointed elements, ashi entering and sunagashi frequent, in deep nioi with ko-nie. Tobiyaki enter on some blades and muneyaki on one, kinsuji on others, and the nioiguchi ranges from tight to somewhat sunken. The Koshu katana of Eiroku 2 is tempered in pointed gunome with ko-choji, strong in nie, its boshi turning ichimai and returning deeply. Elsewhere the boshi runs midare-komi to a ko-maru with a pointed tendency, at times with hakikake or a long return. Bo-hi are the usual carving; a katana with bonji, suken and gomabashi is noted for carvings that are rare in his work. The papers explain the school's manner as strongly influenced by Soshu, Ise and Mino, or by late Soshu and late Seki work.
Two works stand apart. One Juyo katana is called the finest of his oeuvre[[c:4]], and the sources ask whether he privately modeled himself on the manner of Bizen Chogi[[c:5]], since apart from its strong sakizori the build seems exactly that, and the activity within the ha is called superb. A kata-kiriha-zukuri wakizashi, wide and elongated, is a joint work of Motosuke and Hirosuke, described as rare among Shimada blades[[c:6]] and placed between the end of Tenbun and Koji. Of other blades the texts write that the work is splendid and the quality of ji and ha outstanding. His mei is a large two-character 広助 below the mekugi-ana, in several works cut with a thick chisel.
Fujishiro grades him Jo saku. Nine designated works stand on record: seven Juyo, the Koshu katana as a Juyo Bijutsuhin, and one katana recorded in Honma's inventory of the Imperial collection, whose text repeats that Hirosuke's work is most often of the boldest kind. The Hara Toratane inscription is the one provenance his record preserves. The seven Juyo blades are the part of his work a collector may realistically meet, and even these appear on the market only from time to time.
Yoshisuke (義助) — Mainline · 1455-1526. Jūyō. The oldest dated blade to survive under the name Yoshisuke is a tanto signed Suruga no Kuni ju Yoshisuke saku and dated the eighth month of Eisho 2 (1505). Its commentary states that among extant works those with an Eisho date are the oldest[[c:1]]. Yoshisuke is the principal name of the Shimada school of Suruga, a Muromachi group whose work the published sources read as strongly marked by neighboring Sagami. The sword directories place a first generation in the Kosho era and a second around Eisho and Daiei, and the name then continues in succession into the shinshinto period. One directory entry instead assigns a Tensho Yoshisuke to a fourth generation. Honma's inventory of the Imperial collection adds the school genealogy: a Yoshisuke of the Kosho era with the Buddhist name Keizen, and his younger brother Sukemune.
The hand that most distinguishes Yoshisuke is the one carried on the katana. Of the Daiei katana the published sources write that he received strong influence from Sagami work, judging it beyond doubt[[c:2]]. The form is *shinogi-zukuri* with *mitsu-mune*, the curvature shallow and the point an *o-kissaki*. The *itame* flows and stands open, with *ji-nie* adhering and *chikei* entering. Over it he tempers a *notare* with a boxed (*hako*) look that takes in *togariba*, the *nioiguchi* somewhat tight with *ko-nie* and *sunagashi* running. The *boshi* runs *midare-komi*, rounded at the tip with a long return, and is tempered deep. A *bo-hi* finished in *kaku-dome* carries a relief *kurikara* at the waist of the omote and a *sanko-ken* on the ura. The commentary judges ji and ha good and the carving skilled, and adds that in this too the blade is close to late Soshu work[[c:3]].
The quieter half of his work lives on the tanto and the wakizashi. There the *itame* is tightly forged, with areas of *nagare-hada* and a *masame* tendency toward the mune, turning somewhat whitish, with *ji-nie* forming well. The temper is a shallow *notare* mixed with *gunome* on the tanto and a *notare-ba* with *nie* on the wakizashi. On the Eisho tanto it becomes a large *gunome* with a *choji* flavor, tempered deep. The *nioiguchi* is deep and the *nie* adhere well, *sunagashi* runs through, and in places the *habuchi* frays into *hotsure*. The *boshi* is mostly *sugu* to *ko-maru*, and an *ichimai* on the Eisho piece. The carving continues in this register, a *kurikara* within the *koshi-bi* on one tanto and a *bonji* with *suken* and a *shobu-hi* on the wakizashi.
The tanto recorded in Honma's inventory of the Imperial collection widens that register. Its *itame* leans to *masame* and turns whitish, with *tobiyaki* mixed in. The *notare* takes in *gunome*, *sunagashi* runs frequently and *nie* attach, and the *boshi* runs *midare-komi* and returns pointed. The inventory judges this Yoshisuke old among the smiths of the name[[c:4]], while noting that the generations of Yoshisuke and Sukemune are hard to date from their signatures alone. His record therefore reads as two manners sorted by form rather than by date: the Soshu-leaning katana on one side, and the school's tanto and wakizashi on the other.
The dated tangs are what hold these blades against the directory chronology. In the earlier commentary on the Daiei katana, the published sources called Daiei the oldest date among extant works, and the inscription on its tang extremely valuable[[c:5]]. The Eisho tanto, designated later, moved that anchor back to 1505. A tanto placed perhaps after Tenbun draws its own note, for it carries, unusually, an openwork *kurikara*[[c:6]], and it is judged good in ji and ha and a valuable reference piece. The undated *katakiriba-zukuri* wakizashi is placed around Tenbun, its carving well composed and skilled. No successor line can be drawn through any single hand in so small a record. The published sources value these early pieces instead as material for the study of a name that runs through several generations.
Five designated works are on record, four Juyo blades and the tanto of Honma's inventory, all of them signed. He has no National Treasure or Important Cultural Property, and no provenance or institutional holder is recorded for any of his blades. The four Juyo blades are of unrecorded whereabouts and are held rather than traded, so a signed Shimada Yoshisuke of Juyo rank comes to market only occasionally. When one does, its interest lies where the published sources place it: in a dated tang that anchors the school's chronology, in skilled carving, and in the late Soshu character of the katana.
Sukemune (助宗) — Mainline · 1558-1570. Jūyō. Smith of the Suruga Shimada School.
Yoshisuke (義助) — Mainline · 1492-1504. Jūyō. Yoshisuke is the principal mainstream name of the Shimada school of Suruga Province, a Muromachi workshop that the published sources place at the head of all Shimada work. "Within the group of works known as Shimada-mono, the principal mainstream lineage is that of Yoshisuke"[[c:1]], one Jūyō commentary states plainly, and the name carried that standing across several generations. The reference works arrange those generations with the first about the Kōshō era, called Yasumasa, the second about Meiō and Eishō, and successors continuing without break to the end of the Edo period. That neat scheme is the difficulty rather than the answer, for no work bearing a date earlier than Eishō survives, the oldest extant example being an Eishō 2 tantō of 1505 regarded as the second generation. Because the signature style does not separate the hands either, the published record holds that the individual generations cannot be told apart, and a signed Yoshisuke is read for its workmanship rather than assigned a number.
His characteristic hand is a Sōshū-leaning midare. Over the itame the temper is a notare crossed with gunome, the two together appearing on five of his six designated blades, with ko-chōji and pointed elements entering, ko-ashi, a nioiguchi inclining to tighten, and ko-nie adhering, through which sunagashi and kinsuji run. The kinship is stated outright: of one katana the published sources write that the Shimada style "bears a deep relationship with the late Sōshū smiths, and the two groups mutually influenced one another"[[c:2]]. The boshi follows the midare, running to a midare-komi that turns back with a pointed tendency, sometimes a yaki-tsume. Against this typical manner stands an uncommon register the NBTHK itself flags, a narrow suguha that on one late katana the commentary calls "a narrow suguha, comparatively uncommon for Yoshisuke"[[c:3]], the temper there a hoso-suguha with a slight admixture of small gunome, ko-nie adhering and a hotsure-like tendency.
The jigane is the steady foundation beneath both manners. The forging is an itame, well knit and at times dense, that overall flows and leans toward masame, standing somewhat open with hada-dachi on half his blades, fine ji-nie lying through it and a passage of one blade appearing whitish. This flowing, slightly standing itame, rather than a tight Bizen jigane, is what marks the Shimada hand for the eye, and it is the surface on which the nie activity of the ha is laid. On the finest of his blades the result is a jihada and hamon that the published record singles out for clarity, the v12 katana being judged the work in which "both jihada and hamon are especially clear and bright"[[c:4]] among his surviving pieces.
The Shimada workshop ranged widely in form, and Yoshisuke's surviving designations show it. They run from shinogi-zukuri katana with strong sakizori through hira-zukuri wakizashi and an uchizori tantō to a large-bodied yari, the published sources noting that "the Shimada lineage produced comparatively many yari"[[c:5]] and naming his ōmi-yari a superior example among them. His horimono are a school feature carried with skill, bonji and the figure of Marishiten cut in relief within a wide groove, shin and gyō kurikara on the two faces of a wakizashi, suken and gomabashi on a tantō. The mei is cut ubu, either a bare two-character Yoshisuke or a three-character Yoshisuke saku, at times in a fine chisel cut large, and because the dates and signatures will not divide the generations it is the quality of a given blade, not its mei, that the published sources weigh.
What distinguishes Yoshisuke is best drawn from his own grounded traits rather than by contrast. His is the Sōshū-influenced notare-gunome in nie, with sunagashi and kinsuji over a flowing, standing itame, a provincial Suruga reading of the late Sōshū idiom; the narrow suguha is the deliberate exception, and the prominent horimono and the yari are the marks of the broader Shimada shop around him. Where a generational verdict is impossible, the commentary turns to the blade itself, calling the v20 tantō, an ubu hira-zukuri piece with uchizori, "an exceptional blade among works signed with this name"[[c:6]], and reading another katana as a work near the earliest surviving phase. The cut struck into the mune at the monouchi of one of his katana drew a separate remark, the published sources observing that it "speaks to martial use"[[c:7]], a reminder that these were the working blades of a Muromachi province.
Yoshisuke is rated Chū-jō saku by Fujishiro, a solid provincial standing rather than a first rank, and his designated record is modest in scale and entirely signed. Six of his blades hold the Jūyō rank, his record reaching no higher tier, so his work is encountered as Jūyō and lower-ranked pieces rather than as patrimony held permanently out of reach. One blade carries a notable provenance, having been held by the Imperial Family. The number of designated works on record is small, and across the run of generations under one undivided name a securely fine example, of the clarity the published sources praise in his best katana and tantō, is the thing worth waiting for. Such a blade comes to market only from time to time, and when one does it is a good representative of a respected provincial school whose work sits close to the late Sōshū tradition.
Sukemune (助宗) — Mainline · 1444-1449. Jūyō. A katana now in Osaka, designated at the fourteenth Jūyō session in 1966, is judged in its commentary to be "sound in both ji and ha and thought to represent Sukemune's finest work"[[c:1]], and it gives the measure of the man. Sukemune is, with the mainstream Yoshisuke, one of the two principal names of the Shimada school of Suruga Province, a Muromachi workshop on the Tōkaidō between Mino and the late Sōshū hearths. The published sources place him as the younger brother of the founder Yoshisuke in the mid-Muromachi period, and the name carried that standing through several generations down into the shintō era. The reference works arrange those hands across a long run, citing Sukemune work as early as the Bun'an and Bunki eras and then a Sukemune of the Tenbun era, so the name spans the whole Muromachi century. Because the signature style does not separate the generations either, a signed Sukemune is read for its workmanship rather than assigned a number, and the date inscriptions, where they survive, do the work the mei cannot.
His characteristic hand is the connected gunome that the published sources name the school's own. Over the itame the temper is a gunome run together in series, crossed with gunome-chōji and pointed togariba, at times taking a box-shaped form, abundant nie lying through it with tobiyaki, kinsuji and sunagashi, the nioiguchi bright. Of the long katana designated in 2020 the NBTHK writes that "the hamon features the Shimada school's hallmark of connected gunome"[[c:2]] and reads its bright nioiguchi, kinsuji and sunagashi as "features that strongly express the characteristic manner of Sukemune"[[c:3]]. The boshi follows the midare, running midare-komi to a ko-maru with hakikake, on the largest blade strongly covered in nie and tending toward nie-kuzure. This is the manner the published record ties to the late Sōshū smiths, to late Seki and to the Senju group, and reads as close to the work of Mino and Ise.
The jigane is the steady foundation beneath the ha. The forging is an itame, well knit and at times dense, that overall flows and leans toward masame, ji-nie lying through it and chikei entering, with a tendency toward hada-dachi where the grain stands open. On the 2020 katana that jigane is described as a tightly forged itame, partly flowing and tending toward masame, the ji-nie finely granular yet densely applied and the chikei clearly visible, a Suruga reading of the Sōshū surface rather than a tight Bizen jigane. It is on this flowing, slightly standing steel that the nie activity of the edge is laid, and the finest of his blades are praised for the clarity that results, the bright nioiguchi and the streaming kinsuji and sunagashi together.
The designations show the Shimada shop's range of form. Three of the four with commentary are shinogi-zukuri katana, several with strong sakizori or a tachi-like koshizori, one of them an eighty-centimetre blade of robust, tachi-like make rich in hataraki; the fourth is a hira-zukuri tantō of orthodox, curvature-less form. On that tantō the manner shifts to the school's other register, a suguha mixed with small gunome over a flowing itame, sunagashi and kinsuji appearing, which the published sources read as work "made with an eye toward the manner of Shizu"[[c:4]], appraising the piece as older than the Tenbun Sukemune of the meikan. His horimono are a school feature carried with skill, bonji, a grass-script kurikara, a clawed ken, futasuji-hi closed with maru-dome and gomabashi, which the commentary ties to Muromachi carving in general and to the work of the Shimohara smiths.
What distinguishes Sukemune is best drawn from his own grounded traits. His is the connected gunome in abundant nie, with kinsuji and sunagashi over a flowing, masame-leaning itame, a provincial Suruga reading of the late Sōshū idiom that the published sources set beside Mino and Ise work; the Shizu-leaning suguha of the tantō is the deliberate exception, and the prominent horimono is the mark of the broader Shimada shop, shared with Yoshisuke and Hirosuke. Where a generational verdict is impossible the commentary turns to the blade, calling the Osaka katana the finest work of the name, sound in ji and ha, and fixing one hand within the long run by the blade rather than the signature. The last of his katana drew the further observation that, though signed on the sashi-ura in the manner of a tachi, it should be understood as an uchigatana, a reading the NBTHK reaches from the position of the mekugi-ana and the overall sugata.
Sukemune's designated record is modest in scale and entirely signed, four of his blades holding the Jūyō rank with his record reaching no higher tier, so his work is encountered as Jūyō and lower-ranked pieces rather than as patrimony held permanently out of reach. He carries a Tōkō Taikan value of 450 monme, a solid provincial standing rather than a first rank, in keeping with a respected one-province name. One blade of his is recorded in Imperial provenance, the kind of holding from which a Shimada work rarely returns to circulation. The number of designated works on record is small, and across the run of generations under one undivided name a securely fine example, of the soundness in ji and ha that the published sources praise in his Osaka katana, is the thing worth waiting for. Such a blade comes to market only from time to time, and when one does it is a good representative of a provincial school whose hand sits close to the late Sōshū tradition.
Yoshisuke (義助) — Mainline · 1573-1592. Jūyō. Smith of the Suruga Shimada School.
Other smiths
Motosuke (元助) — Mainline · 1532-1555. Smith of the Suruga Shimada School.
Sukemune (助宗) — Mainline · 1661-1673. Smith of the Suruga Shimada School.
Yoshisuke (義助) — Mainline · 1394-1428. Yoshisuke (義助) was the principal mainstream smith of the Shimada school of Suruga Province (Sunshū). According to *meikan* sources, the first generation is placed in the Kyōshō era, with successive generations continuing the same name without interruption from the Muromachi period through the *shinshintō* era. However, it is difficult to distinguish these generations with precision, and among extant works, the earliest dated examples bear inscriptions from the Eishō era (1504-1521). The Shimada lineage in general is noted for their affinity with the workmanship of Mino, Ise, and *Sue-Sōshū* traditions, and Yoshisuke stands as the school's most prominent representative.
The forging across designated works typically presents *itame-hada* mixed with *mokume*, often with the grain standing out (*hada-dachi*) and a tendency toward *masame* near the edge, accompanied by *ji-nie* and a somewhat whitish tonality. The *hamon* ranges from *chū-suguha* mixed with *ko-gunome* to *gunome-midare* incorporating *togariba* and *ko-notare*, frequently with thick *nie*, *sunagashi*, and *kinsuji*. The *habuchi* characteristically shows *hotsure*, and the *bōshi* often exhibits *hakikake*. This repertoire demonstrates considerable versatility, from the archaic quality (*kochō*) observed in early-period katana to the forceful intensity found in later tantō and wakizashi. The school also produced comparatively many *yari*, and Yoshisuke's spearwork -- including *ōmi-yari* of substantial proportions -- exhibits an unbroken, well-composed style.
Yoshisuke's tantō and wakizashi are frequently encountered in *hira-zukuri* with *mitsu-mune*, often displaying thick *kasane* and the distinctive withered *fukura* (*fukura kare*) characteristic of the school. Several designated pieces bear skillfully executed *horimono*, including relief carvings (*ukibori*) of Fudo Myōō and openwork (*sukashi-bori*) -- the latter noted by examiners as an uncommon feature for this smith. The dated Genki 2 (1571) tantō provides valuable documentary material for study of the lineage's later generations.
