    Tokubetsu hozon certificate № 2002993 of the N.B.T.H.K., dated January 15, 2016. NOBUIE TSUBA by Steve Waszak The iron tsuba made by the two early Nobuie masters are regarded as the greatest sword guards ever made across hundreds of years of Japanese history.  Only a small handful of other smiths' names are even mentioned in the same breath as that of Nobuie.  Despite the well-deserved fame of the Nobuie name, virtually nothing is known with certainty about the lives of the two men who made the pieces carrying this name.  They are thought to have been men of Owari Province, with the Nidai Nobuie also spending time in Aki Province at the end of the Momoyama Period. Two Nobuie tsubako are recognized.  The man whom most consider to have been the Shodai signed his sword guards with finer and more elegantly inscribed characters than the smith seen by most as the Nidai.  The term used to describe the mei of the Shodai is "hanare-mei" or "ga-mei," while that used to characterize the signature of the Nidai is "futoji-mei" or "chikara-mei."  These terms refer to the fineness and grace of the Shodai's signature and the relatively more powerfully inscribed characters of the Nidai's.  The Shodai is thought to have lived during the Eiroku and Tensho eras in the latter part of the 16th century, while the Nidai's years are considered to have been from Tensho into the Genna era.  This locates both smiths well within the Golden Age of tsuba artists -- the Momoyama Period. Nobuie tsuba are esteemed and celebrated for the extraordinary beauty of their iron.  The combination of the forging of the metal, the surface treatment by tsuchime and yakite married to powerfully expressive carving, the masterful manipulation of form, mass and shape, and the colour and patina of the iron makes Nobuie sword guards not only unique in the world of tsuba, but the greatest of the great. The sword guard here is a Shodai-made masterwork, done in mokko-gata form, a shape the early Nobuie smiths mastered to a degree unmatched by any others.  The expanding of the mass of the tsuba from the seppa-dai to the mimi, increasing by 50% from the centre of the guard to the rim, creates a sense of exploding energy, which is then contained by the uchikaeshi-mimi, yielding a lightning-in-a-bottle effect of captured energy.  The hammering the master has employed to finish the surface is subtle and sensitive, achieving a resonant profundity, and the deep blue-black colour -- augmented by a lustrous patina -- leaves the tsuba to positively glow in one's hand.  In this piece, Nobuie has used a motif of several kamon, or family crests, each carved only lightly on the surface in a loose ring around the nakago-ana.  Due to the shallow depth of this carving, together with the tsuchime finish of the plate, the effect is to leave the kamon with a sort of weathered appearance, recalling the prime aesthetic values of sabi and wabi, which had great circulation in the Tea Culture so ascendant in the Momoyama years.  However, the effects of sabi and wabi expressed in the treatment described above are amplified and deepened by the color and patina of the iron, thereby adding yet another aesthetic value -- yuugen -- which is linked with the abiding mystery of the universe and one more — mono no aware — which alludes to the pathos of life's experiences and transitory nature.  In short, this Nobuie tsuba joins poetry with power and therein exemplifies the unrivalled brilliance of Nobuie workmanship.
  • A circular iron tsuba with a design of three monkey toys (kukurizaru) in small openwork (ko-sukashi); the plate further decorated with four rows of brass dot inlay (ten-zogan). The center of the plate and the openings are outlined with brass wire. Copper sekigane. A few dots missing. Muromachi period. Dimensions: 89.0 x 88.2 x 2.9 mm. Kukurizaru was an often used motif on old tsuba. The symbol has two explanations: (1) "upright" monkey, a sort of roly-poly toy, alludes to 'never-ever give up' property of the samurai; (2) monkeys are represented with their hands and feet tied to their back to symbolize self-control. Other examples of the same design:

Design is supplemented with a round family crest (mon) of three fans in openwork (sukashi). Hitsu-ana and the mon are outlined with brass rope. Copper sekigane.

    Some attribute such tsuba as belonging to Heianjō or even Yoshirō School, and date them to Momoyama period. I keep this piece under Ōnin rubric, late Muromachi, but this is just a question of personal preference.

    Some inlay is missing, some repaired; traces of rust. Otherwise - decent condition.

  • The thin, four-lobed iron plate of brownish color is carved on each side with two concentric grooves in the middle of the web, and with four thin scroll lines (handles, kan) that follow the shape of the rim. The hitsu-ana were added at a later date.  Copper sekigane. Kamakura-bori school. Muromachi period, circa 1400-1550. Size: Height 80.4 mm, width 79.0 mm, thickness 3.2 mm at seppa-dai and 2.7 mm at the rim. Weight: 97.7 g. NBTHK Certificate №4004241: 'Hozon' attestation. As for the motif: the concentric circles is a widespread and generic design. It is described by John W. Dower [The Elements of Japanese Design, 1985, p. 132, #2201-30] as follows: Circle: Enclosure (wa). As a crest by itself, the cirlce carries obvious connotations of perfection, harmony, completeness, integrity, even peace. [...] Ordinary circles are labeled according to their thickness, with terminology ranging from hairline to "snake's eye". The motif that is described by both Compton Collection and R.E. Haynes as "scrolls", presented by John W. Dower as "Handle (kan): Although probably a purely ornamental and nonrepresentational design in origin, over the centuries this motif acquired the label kan, denoting its resemblance to the metal handles traditionally used on chests of drawers. [...] Very possibly the "handle" motif represents an early abstract version of the popular mokko, or melon pattern." Early Chinese Taoists claimed that special melon was associated with the Eastern Paradise of Mount Horai just as life-giving peaches were associated with the Western Paradise of the Kunlun Mountains. [...] A design motif called mokko (also translated as "melon" in accordance with the two ideographs with which it is written) may have nothing to do with the fruit. Mokko designs... are widely used as crests of both private families and Shinto shrines and are repeated as background designs that evoke a sense of classicism" [Symbols of Japan. Merrily Baird, 2001]. There is a look alike tsuba at Dr. Walter A. Compton Collection, 1992, Christie’s auction, Part II, pp. 14-15, №16: The description goes: “A kamakurabori type tsubaMuromachi period, circa 1400. The thin, six-lobed iron plate is carved on each side with a wide groove that follows the shape of the rim, and with six scroll lines and a single thin circular groove. […] The hitsu-ana was added at a later date, circa 1500-1550.  Height 8.3 cm, width 8.6 cm, thickness 2.5 mm. The tsuba was initially intended  to be mounted on a tachi of the battle type in use from Nambokucho to early Muromachi period (1333-1400)”. Sold at $935. And another one in Robert E. Haynes Catalog #9 on page 24-25 under №23: R.E. Haynes description: “Typical later Kamakura-bori style work.

  • Iron tsuba of round form with design of water plantain (omodaka) and wild goose in openwork (sukashi). Slightly rounded, square rim. Copper sekigane. Kyo school. Late Muromachi period: Early 16th century (Tenbun era) [Sasano's attribution]. Height: 76.2 mm. Width: 75.8 mm. Rim thickness: 5.3 mm. Center thickness: 4.5 mm. Provenance: Sasano Masayuki Collection, № 68: "The water plantain (omodaka) first appeared as a design for sword fittings in the Heian period. From such early beginnings, this decorative plant has shared a long history with the samurai. Also known as shogun's grass (shogununso), it was held in high esteem as a symbol of victory". The same tsuba was found at Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections. Sotheby's, London, Thursday 10 April 1997, page 22, item 60, saying that this is a "Kyo-sukashi tsuba, early to middle Edo period (late 17th/18th century) [Sotheby's attribution], and that it represents "a small bird among omodaka and aoi plants".  
  • Ko-kinko ymagane cast tsuba of mokko form (kirikomi-mokkō-gata) with chiseled diaper pattern of double head waves on both sides and a rabbit cast and carved with its eye inlaid in yellow metal (gold or brass) on the face. Fukurin which holds together the sandwiched layers of metal (sanmai) is about 2.4 mm wide. A look-a-like tsub of oval form instead of mokko-gata  is illustrated at Robert E. Haynes's Catalog #3,1982 on page 11, lot 15: "Rare design in style of Sanmai (three layers) / Wasei work. With yamagane core and heavy rim cover. The web plates are carved with double head Goto style waves and the face has a fox. The web plates were riveted at the seppadai.  See Lot 4, page 8. Ca. 1350. Ht. 6.6 cm, th. 3 mm" [underscore mine]. Quality of photo is so poor that I decided not to provide it here. Muromachi (if we follow Robert) or Momoyama period. The Momoyama attribution is mostly based on a fact that "waves and rabbit" motif became most popular in Momoyama times. Size: 68.5 x 59.8 x 4.0 mm. NBTHK Certificate № 423120. This tsuba is listed at Yakiba website with the following passage: "Attributions as well as dating of this type of tsuba has been the subject debate over the years. There are those who believe these type of tsuba to be ko-Mino (early Mino School) tsuba, others believe them to be tachi-kanaguchi tsuba. Still others insist they are simply ko-kinko (early soft metal) tsuba. This tsuba was authenticated and determined to be "Ko-Kinko" by the NBTHK". Oval form tsuba with the same design can be found in this collection - TSU-0323.

  • Iron tsuba of round form with design of rabbit (usagi) in openwork (sukashi) and inlaid with designs of plants and family crests (mon) in suemon-zōgan. A branch with lonely leaf, half chrysanthemum, and flying wild geese on the face represent autumnal connotations. The same motif is complemented by a clove (choji) on the reverse.  The family crests (mon) include: interlocked rings (kanawa; wachigai), three encircled lines or stripes (hikiryo), bit or muzzle (kutsuwa - horse's harness element with possible christian symbolism), and encircled triangle (uroko, fish scale).

  • Iron tsuba of round form with design of slanting rays of light (shakoh) or clock gear (tokei) in openwork (sukashi). Commonly considered a Christian / Jesuit motif. Round-cornered rim. Copper sekigane. Momoyama period: Late 16th century (Tensho/Keicho era). Height: 72.5 mm, Width: 72.2 mm, Rim thickness: 5.5 mm, Center thickness: 5.3 mm. Round-cornered rim. Provenance: Sasano collection. Sasano Masayuki, Japanese Sword Guards Masterpieces from The Sasano Collection, Part I, № 136: "The general belief that this design represents the gear of a clock is erroneous, rather it shows the slanting rays of light from a cross, with the small diamond shapes representing the upright and transverse bars. The Christian influence is obvious..."  
  • Iron tsuba of octafoil form with design of rudder (kaji) and lake in openwork (sukashi) outlined with brass wire. Thin plate also decorated with three concentric circular rows of brass dots (nail heads) in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire. Cut-outs for kozuka and kogai probably added later.  Slightly raised rim between the indentations (suki-nokoshi-mimi). The inlaid metal of red-ish hue, so it may be copper, not brass. Sekigane, visible on the NBTHK paper photo, are missing, possibly removed by a previous owner. Muromachi period. Ōnin school. Unsigned. Dimensions: 81.2 mm x 81.8 mm x 2.7 mm. Weight: 79.0 g. Large nakago-ana: 34 mm high and 10 mm wide. NBTHK certificate №455786: Hozon. Note regarding design: it was quite hard to interpret the big oval opening. The first suggestion was 'sea cucubmer', and it was based on a design published by Kazutaro Torigoye [Kodogu and tsuba. International collections not published in my books (Toso Soran), 1978] on page 202: Katchūshi tsuba: Sea cucumber and butterfly. Look and judge yourself:

    Torigoye: sea cucumber and butterfly.

    The second suggestion - 'lake' - came from [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014], page 14 №5:

    Ko-Katchūshi tsuba: Lake and pine.

    Opening on my tsuba looks more like the 'lake'. Also, rudder and lake make more sense than rudder and sea cucumber. At least to me...    
  • Small iron tsuba for a dagger (tantō), of quatrefoil form (mokkō-gata), with raised rim (mimi), decorated with flat brass inlay (hira-zōgan) to form an abstract design alluding to the mushroom of immortality (reishi). Opening (hitsu-ana) to the left of nakaga-ana probably cut later and fitted with shakudo sekigane. Maker's signature on seppa-dai: Koike Naomasa (小池 直正).

    Momoyama period: End of the 16th - beginning of the 17th century. Dimensions: Height 53.7 mm; Width: 45.5 mm; Thickness at centre: 3.5 mm; at rim: 4.9 mm.

    Compton Collection, part II, pp. 14-15, №17: Kamakura-bori tsuba, ca. 1450.

    NBTHK paper says that the motif is Hakkei (八景), i.e. "Eight Views," so several interpretations are possible (the original Chinese ones, Omi Hakkei, etc.).  However, most likely it is the 'Eight views of Omi' (近江八景  - 'Omi Hakkei'). Why the artist selected a 6-lobed form for depicting 8 views remains unclear, and thus we are in our right to raise the question whether the motif is indeed Hakkei. The term Omi hakkei (eight views of Omi) refers to painting or print sets which illustrate life on the shores of Lake Biwa in Omi (now Shiga Prefecture). The model for such paintings came from China, where, from the eleventh century onward, painters had produced eight views of the Hsiao and Hsiang lake areas of Hunan Province. The themes, which follow the original Chinese models, are: geese descending to land, returning fishing boats, clearing rain, a snow-covered evening landscape, the autumn moon, night rain, a temple bell at evening, and the glow of sunset. Japanese artists have also used the eight-theme approach for other parts of country - including cities - and applied it to subject matter other than landscapes. [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, page 308-9]. Japan Encyclopedia by Louis Frédéric also mentions Omi Hakkei as "Eight landscapes of Omi", and states that this theme was often cited in poetry after 1500. It is likely that the tsuba in focus is designed under the influence of the theme popularity in the 16th century. The theme was effectively exploited by prominent ukiyo-e artists Suzuki Harunobu and Utagawa Hiroshige in the 18th and 19th century, respectively. These are the eight scenes of the theme (see Wikipedia):
    • Returning sails at Yabase (矢橋の帰帆) - Yabase. Yabase is an old harbour on the east side of the lake. Near the Tokaido, it was used for a shortcut to Otsu by boat.
    • Evening glow at Seta (勢多(瀬田)の夕照) - The Chinese Bridge at Seta. The long bridge across the Seta was used by the Tokaido. In the background the "Fuji of Omi", the Mikamiyama. It is just above 400 m, but indeed well visible.
    • Autumn moon at Ishiyama (石山の秋月) - Ishiyama Temple. The Ishiyamadera was located on a hillside next to the Seta River. It got his name form the strange rocks on which it is built, partly on supporting beams. A hut at the upper end of the site allows a view of the lake, and the moon.
    • Clear breeze at Awazu (粟津の晴嵐) - Awazuhara. Awazu is well known for its pine wood, Awazu-ga-hara.
    • Evening bell at Miidera (三井晩鐘) - Mii-dera. Miidera temple was built in the 8th century. Its famous bell is one of the "Three bells of Japan", the other two being those at Byoodo-in, Uji and at Jingoji, Kyoto.
    • Evening rain at Karasaki (唐崎の夜雨) - Karasaki Shrine. Karasaki is a small cape with a single large pine tree, a hitsu-matsu.
    • Wild geese returning home at Katata (堅田の落雁) - Ukimido. Alighting geese cannot be seen always, however the little temple near Katata in the square hōkyō-style, detached from the lakeside, connected by a bridge. The first part of the name uki is the same as in Ukiyo-e, meaning floating. Midō means temple.
    • Evening snow at Hira (比良の暮雪) - Hira Mountains. The Hira mountains on the west side of the lake experience the hard winter, when the winter monsoon brings much snow from the continent.
    In any case, as a conservative, I say that it is a landscape motif and a late Muromachi period work, rather than Omi hakkei motif and a mid-Muromachi work.
  • Iron tsuba of round form with brown patina decorated with the design of a Buddhist temple bell (tsurigane) in openwork (sukashi), with details outlined in brass wire (sen-zōgan), the outer ring  decorated with two rows of brass dots (ten-zōgan), and the bell details carved in sukidashi-bori as on kamakura-bori pieces.

Interestingly, this type of bell (tsurigane) is not described as a family crest (mon), while suzu and hansho bells are.

  • Tsuba of chrysanthemoid form (kikka-gata) with yamagane core and woven copper wire pattern. Copper sekigane. Shingen school. Height: 70.2 mm; Width 67.2 mm; Thickness at seppa-dai: 3.4-3.6 mm, overall 7.3 mm. Weight 82.7 g Inscription on the wooden box reads: "Muromachi period Mumei Zōgan Shingen Tsuba" Muromachi period, 16th century. Age attribution is based on the fact that the core is made of yamagane; later copies of Edo period are usually made of iron. This small and light tsuba was likely mounted on a combat sword, while larger and much heavier woven wire Shingen tsuba of Edo period were of purely decorative purpose. http://varshavskycollection.com/shingen-tsuba/
