• 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...    
  • 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). Brass wire trim around the openwork elements and the seppa-dai, scalloped wire inlay around the hitsu-ana. Iron is dark, almost black. Brass or copper elements vary in shades of lighter and darker yellow with red-ish hue. Ōnin school. Late Muromachi period, 16th century. Height: 89.6 mm; Width: 89.3 mm; Thickness at seppa-dai: 3.0 mm. Weight: 129.7 g.
  • Iron tsuba of half round and half lobed (chrysanthemoid) form decorated with plants and family crests (mon) in cast brass inlay (suemon-zōgan), and scattered brass dots inlay (ten-zōgan); brass wire inlay outlining the rim, seppa-dai, and hitsu-ana (scalloped wire) on both sides. Surface treated with hummer punch marks. The chrysanthemoid half of the plate chiseled  with thin shallow grooves, outlining the petals. Copper sekigane. On the face the inlay represents: mandarin orange (tachibana), half karahana, encircled bellflower, and four encircled three-stipe family crest (mitsubiki-mon of Sakuma and Abe clans, and some others). On the reverse the design is similar but two of the mitsubiki-mon symbols replaced with two comb-shaped Genji-mon ideographs. Ōnin school. The end of mid-Muromachi period, beginning of the 16th century. Size: 74.3 x 72.7 x 2.4 mm.  
  • Iron tsuba of round form decorated with floral motif in brass or copper inlay (suemon-zōgan) and family crests (mon) in small openwork (ko-sukashi). Occasional brass dots or nail heads in brass ten-zōgan. Sukashi elements outlined with inlaid brass wire. Seppa-dai outlined with rope-shaped brass wire (nawame-zōgan); kozuka-hitsu-ana outlined with scalloped brass wire. Ōnin school. Mid to late Muromachi period, 15th or 16th century. Height: 88.9 mm; Width: 88.5 mm; Thickness at seppa-dai: 2.9 mm. Family crests (mon) in openwork: cherry blossom (sakura) - kamon of Sakurai and Yoshino clans, four-section lozenge (waribishi) - kamon of Takeda clan, the seven stars of the big dipper (maru ni nanatsuboshi) - kamon of Chiba clan, two encircled stripes (futatsubiki) - kamon of Ashikaga clan. Brass inlays represent flowers, branches and leaves, as well as halved plum blossom, halved chrysanthemum blossom, cloud, and chrysanthemum-on-water symbol - the mon of Kusunoki Masashige. Abundance of family crests of so many powerful warrior clans symbolizes heritage. "The brass trim around the kozuka hitsu-ana andd the seppa-dai are characteristics of Onin work" [Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]
  • Iron tsuba of round form decorated with chrysanthemums, pine cones and needles, pampas grass, vines, cherry blossoms, and wild geese in brass inlay (suemon-zōgan) and pierced with designs of water clover (denjiso) and half bellflower (or karahana) to the left and to the right of nakago-ana as well as double bars above and below nakago-ana (possibly with the meaning of number 2 or ordinal 2nd). Most probably the sukashi elements here are the family crests (mon). Unsigned. Ōnin school. Muromachi period; 15th or 16th century. Height: 82.1 mm; Width: 80.9 mm; Thickness at seppa-dai: 2.4 mm NBTHK # 2003827: Tokubetsu Hozon Tosogu Kanteisho (特別保存刀装具鑑定書) - "Extraordinarily Worthy of Preservation".
  • Iron tsuba of round form inlaid with brass and shakudo (suemon-zōgan) with a design of tendrils, leaves, double gourds, and folding fan with two wild geese on the face and the same design only with a fan with two interlocked rings (wachigai) on the back. 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.

    Late Muromachi period (1514-1573). Size: 77.4 x 77.1 x 3.8 (center), 3.2 (rim) mm
  • Iron tsuba of mokko form (quatrefoil) decorated with a pair of cherry blossoms (sakura) in small openwork (ko-sukashi) and inlaid in brass (suemon-zōgan) with designs of waves, distant pines, chrysanthemum flowers in halves, tendrils and leaves, lightning or thunder symbol (inazuma), flying geese and family chrests (mon): two interlocked rings (wachigai) on the face, and three encircled stripes (maru-no-uchi-ni-mitsuhikiryo) - kamon of the Kikkawa clan  - on the reverse. Hitsu-ana outlined with inlay of brass wire. Surface treated with lacquer. Copper sekigane. Though some consider this type of tsuba to resemble Heianjo school, “...the brass trim around the hitsu-ana is a characteristics of Ōnin work” [Japanese sword guards. Onin – Heianjo – Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]. The Ōnin origin is reinforced by scattered ten-zōgan elements here and there through the plate. It is possible that the tsuba was initially of round form and later trimmed to mokko shape. Mid Muromachi period; 15th century. Dimensions: Height: 87.2 mm; Width: 87.9 mm; Thickness at seppa-dai: 3.6 mm.
  • Thin iron tsuba of round form with design of family crests (mon) and arabesque (karakusa) in brass or copper inlay (suemon-zōgan) and occasional scattered brass dots or nail heads in ten-zōgan. Seppa-dai outlined with brass wire in the shape of a rope; kozuka-hitsu-ana outlined with scalloped brass wire. Rounded rim with iron bones (tekkotsu). The surface covered with lacquer (urushi). Ōnin school. Late Muromachi period, 16th century. Family crests on the face: 1:30: Two lines (double stripe) encircled (maruni futatsu biki). 4:30: Stylized clove (choji). 7:30: Divided rhombus, or four lozenges incorporated in one (wari-bishi); it is also called Takeda-bishi, the family crest of warrior Takeda Shingen (among the others). 10:00: Stylized Genji-mon (Genji kō-zu) or incense symbol. On the reverse: 2:00 - "Chinese cloud" not a crest. 5:00: Bit (Kutsuwa) 7:30: Number four in a fan (ōgi-san) 10:30: Two dots in a well frame (igeta).      
  • Iron tsuba of round form profusely decorated with brass inlay of plants, birds, well, and family crests (mon) in suemon-zōgan technique and occasional brass dots (nail-heads) or ten-zōgan. Seppa-dai and kozuka-hitsu-ana outlined with brass inaly, possibly repaired: rope-shaped wire here and there replaced with flat wire. The plate is very thin, with remnants of lacquer. Ōnin school. Size: 75.8 x 75.2 x 2.3 mm. Weight: 77.5 g. On the front side (omote) motif includes the following elements (from 12 o'clock, clockwise):
    1. Water plantain (a.k.a. arrowhead, or omodaka): "a perpetual plant of the water plantain family, was also called shōgunsō (victorious army grass). Because of this martial connotation, it was a design favored for the crests of samurai families" [see: Family Crests of Japan. // Stone Bridge Press, Berkeley, CA, 2007; p. 63].
    2. Heron (sagi): "...considered an emblem of longevity, and from China comes the practice of regarding the bird as a mount of the gods and the Taoist sennin. [...] heron also reflects an inauspicious connotation, for the word sagi is homophone for 'fraud' and 'false pretenses'." [see: Merrily Baird. Symbols of Japan. Thematic motifs in art and design. // Rizzoli international publications, Inc., 2001; p. 112]. Some may say, that this is not a heron but a crane (tsuru). It's very possible, and in this case the negative connotation is lost, but the reference to longevity and allusion to sennin remain.
    3. Pampas grass (susuki, or obana): as per Merrily Baird, p. 95 and John W. Dower, p. 66, pampas grass is one of the Seven Grasses of Autumn. When combined with flying wild gees, conveys strong autumnal mood.
    4. Plum blossom (ume): according to Merrily Baird, the flower has a vast variety of symbolic meanings, including longevity, and a reference to the Chinese Taoists. It is used in 80 family crests [see: Japanese Design Motifs: 4,260 Illustrations of Japanese Crests; Compiled by the Matsuya Piece-Goods Store; Translated by Fumie Adachi. // Dover Publications, Inc., 1972.] Plum is "celebrated for its sweet perfume, delicate blossoms, and habit of blooming at the end of winter".
    5. Tree flying wild geese (kari): "Wild geese arrive in large flocks in southern regions during the autumn months, and following their migratory instincts, head back north in spring" [Family Crests of Japan, pp. 85-86]. "The importance of geese in Japanese art was further secured by stories of several military heroes who had achieved victory in battle when a sudden breaking of ranks by flying geese signaled an ambush. The protective role of the birds led to their frequent use in decorating sword furnishings and possibly also their adoption as a family crest motif.Finally, the goose in Asia plays a role in religious traditions" [Merrily Baird, pp.111-112].
    6. Hikiryō (line, or bar, or stripe) - a symbol which consists of one, two, or three horizontal or vertical stripes in a circle. "In wartime, Japanese generals [...] surrounded their encampments with huge cloth curtains. Usually these were made of cloth sewn together horizontally and varying in color [...] to distinguish the individual general and his followers. The stripe thus assumed strong martial connotations, and became a mark of identification on personal military gear as well. In the early fourteenth century  the heads of the Ashikaga and Nitta, then the two most powerful clans in Japan, both adopted stripe patterns as a family crest". [See: Family Crests of Japan, p. 111 and John W. Dower. The elements of Japanese design - A handbook of family crests, heraldry & symbolism. // Weatherhill, New York, Tokyo, 1985, p. 144].
    On the reverse (ura) motif includes the following elements (from 12 o'clock, clockwise):
    1. Hikiryō, see above.
    2. Pampas grass (susuki, or obana), see above.
    3. Bellflower (kikyo): One of the Seven Grasses of Autumn. "As a crest, it have been adopted among the warriors around the thirteenth century, primarily because of it's beauty" [John W. Dower, p. 48].
    4. Four flying wild geese (kari), see above.
    5. Weeping willow (yanagi): "It is commonly represented with water, snow, swallows, or herons.  A branch of willow (yoshi) is one of the attributes of the Buddhist deity Senju Kannon (Thousand-Armed Kannon), who is said to use the branch to sprinkle the nectar of life contained in a vase. [Merrily Baird, pp. 66-67].
    6. Lone plum blossom in a well frame/crib (igeta, izitsu): "Well crib was one of the most popular motifs in Japanese heraldry".  As a crest it may stay simply for the first character (i) of the family name, however, with a flower inside the well frame, and together with the other symbols present, it may aggravate the sense of autumn-ness. The ten-zōgan dots in this particular case may represent the snowflakes or autumn stars.
    The beholder may imagine a high-ranking samurai resting near a river or lake after the battle. Surrounded by clusters of pampas grass, he's watching a flock of geese flying in the skies; it is late in the autumn, and the occasional snowflakes hover around; heron is walking amidst the arrowheads, hunting for food. The last lonely plum blossom floating in a well... According to Gary D. Murtha, this type of tsuba "could be considered as Onin or as early Heianjo work. The brass trim around kozuka hitsu-ana and the seppa-dai are characteristics of Onin work [see: Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27].  
  • Iron tsuba of round form, slightly convex, decorated with persimmon (kaki), simplified Genji-kō (incense game symbol) and halves of plum blossoms (ume) in brass inlay on both sides, and with part of bellflower (kikyo) in openwork. Outer rim, seppa-dai, bellflower openwork, and kozuka-ana outlined with brass inlay; traces of lacquer to surface. The symbolic meaning alludes to Chapter 20: Asagao (朝顔, the bellflower or "morning face") of Tale of Genji by Murasaki Shikibu (11th century AD). The events take place in the 9th lunar month (Nagatsuki) and involve the following poetry by Prince Genji: saku hana ni / utsuru chō na wa / tsutsumedomo / orade sugiuki / kesa no asagao [I would not have it said / that my heart has turned toward / a flower in bloom — / yet how hard it is to pass / without plucking a “morning face”!]. Measurements: H: 76.6 mm; W: 76.3 mm; Th.: 3.6 mm (seppa-dai), 3.0 mm (rim) Time: Late Muromachi (1514 – 1573).
  • Iron tsuba of quatrefoil form (mokka-gata) adorned with the design of stars, wild geese, blossoms, leaves and tendrils realized in the brass inlay. The inlay technique includes suemon-zōgan and ten-zōgan. A smaller opening (kozuka hitsu-ana) surrounded by a scalloped brass border. The seppa-dai bordered with linear inlay. A few dots of inlay on both sides are missing. Measurements: height 71 mm, width 70 mm, thickness at centre 2.7 cm Time: Late Muromachi (1514 – 1573)  
  • Iron tsuba of a round form (maru-gata) pierced (sukashi) with two six-petal flowers at 6 and 12 o’clock and modified lozenges at 3 and 9 o’clock, and inlaid in brass (suemon-zōgan) with tendrils and flowers (chrysanthemum, cherry blossom, Chinese bellflower, paulownia); openings outlined with scalloped brass wire. The plate is slightly concave with traces of lacquer on the surface. Nakago-ana plugged with copper sekigane. Some elements of inlay missing. The rim with conspicuous tekkotsu, quite worn. Measurements:  Height 92.0 mm; Width 86.3 mm; thickness at seppa-dai 3.2 mm, at rim 4.2 mm. Time: Late Muromachi (1514 – 1573) or earlier.
  • Large iron tsuba with hammer marks on the surface, small oval opening to the right of nakaga-ana; yamagane fukurin chiselled with tortois shell diaper pattern.

    Early Muromachi period (1393-1453). Size: 101.2 x 101.9 x 2.4 (center), 5.2 (rim) mm; weight: 148.4 g.  
  • Iron tsuba of mokkō-form with a pine and a frog on the face and a snail on the back, carved and inlaid with gold. Each figurative element of the design is signed on three inlaid cartouches: Masaharu (正春), Kazuyuki (一之), and Yoshikazu (良一) [read by Markus Sesko]. Snake, snail, and frog together make a design called "SANSUKUMI" - Three Cringing Ones [Merrily Baird]. The snail can poison the snake, the frog eats the snail, and the snake eats the frog. It's unclear whether the pine replaces the snake on this tsuba, or the snake is hiding in the pine? Anyway, the frog and the snail are clearly represented. "Maybe we have here a joint work with Masaharu (the silver cartouche next to the pine) being the master and making the plate and Kazuyuki and Yoshikazu as his students carving out the frog and the snail respectively". Copper sekigane.

    Dimensions: 70.9 x 67.2 x 3.0 mm. Edo period (18th century).

    Markus Sesko writes: "I agree, the frog and the snail most likely allude to the san-sukumi motif. It is possible that we have here an artist's choice to deliberately leave out the snake, maybe he thought that the motif is already obvious and there is no need to add a snake to make it clear that the tsuba shows the san-sukumi motif." [Markus Sesko].

    Kazuyuki (一之): adopted son of Kumagai Yoshiyuki, student of Ichijō (Gotō-Ichijō Scool) [M. Sesko 'Genealogies', page 19.] Masaharu (正春): Kasuya fam., student of Masamichi (1707-1757) who was the 4th generation Nomura School master in Edo. [M. Sesko 'Genealogies', page 49.]

    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.
