• Iron tsuba of round form decorated with inlay of four concentric rows of brass dots or nail heads (ten-zōgan) and a circular brass wire inlay inside the innermost row of dots. Copper sekigane. Muromachi period, 15th or 16th century. Unsigned. Ōnin school. Size: 87.9 x 87.8 x 2.2 mm. Ōnin school got its name from the Ōnin War (応仁の乱 - Ōnin no Ran) - a civil war that lasted 10 years (1467–1477) during the Muromachi period in Japan.
  • 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, on both sides decorated in low relief (kebori) with a dragon, eyes inlaid in brass. NBTHK: Hozon, № 4011013. Kamakura-bori type of tsuba. Med-Muromachi period, c. 1450. Diameter: 90 mm; Thickness (centre): 3.3 cm, Thickness (rim): 2.4 cm Reference: Japanese Swords and Sword Fittings from the Collection of Dr Walter Ames Compton (Part I). — NY: Christie's, 1992, p. 10, №2. Obviously, Compton's tsuba has an altered nakago-ana and placed on the photo upside down. Compton's tsuba has a raised mimi, while mine does not. Two other examples of the same design may be found at: (1) Christie, Manson & Woods auction sales “Kotetsu”, 1980, page 12, №10 and (2) Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections №36, pp. 18-19. Both have raised mimi, the latter classified as Katchushi tsuba. More about Kamakura-bori tsuba here.  
  • 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".  
  • Iron tsuba of round form represents an eight-spoke Wheel-of-the-Law and in the same time (because of the inner shape of cut-outs) - a sixteen-petal imperial chrysanthemum in openwork (sukashi). Decorated on both sides with vines, leaves, and tendrils in suemon-zōgan and sen-zōgan. Spokes and hitsu-ana decorated with rope-like linear brass inlay (nawame-zōgan). A somewhat look-a-like tsuba is referenced in Gary D. Murtha's Japanese Sword Guards. Onin-Heianjo-Yoshiro book on page 61. Mr. Murtha attributes his piece to Heianjo school of Azuchi-Momoyama or early Edo period. However, tsuba in this collection looks older and bolder than the one in his book. It is larger (84 mm vs. his 66 mm), the spokes are longer, the inlay is of better quality, it is relatively thin, with deep black patina, and with the traces of lacquer (urushi). This may indicate that this tsuba belongs to Ōnin school and dates at least to late Muromachi period, ca. 1550, if not 1450 AD. Mid to late Muromachi period (ca. 1450-1550). Dimensions: 84.3 x 83.2 x 3.2 mm "In Japan, the Wheel-of-the-Law is an attribute of such deities as  Senju Kannon, the Thousand-Armed Kannon, and Dainichi Nyorai, the principal deity of Shingon Buddhism [Merrily Baird]. May be used as a family crest (mon).

  • 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. This type of plate and carving show the uniform work produced by several schools in the Muromachi period. Some had brass inlay and others were just carved as this one is. The hitsu are later.

  • Iron tsuba of square with cut-off edges form (sumi-iri-kakugata) with lattice design in openwork (sukashi) and solid center. Hitsu-ana plugged with lead.

    Unsigned. Late Muromachi period, ca. 16th century.

    Size: 81.3 x 80.0 x 3.6 mm References: 1) Tsuba Kanshoki. Kazutaro Torogoye, 1975, p. 95, lower image. It's also called Kyō shōami. 2) KTK-11: Koshi motif, Late Muromachi (16th c.)
  • Ko-kinko ymagane cast tsuba of oval form 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 2.7 mm wide. Possibly, early Mino (ko-Mino) school. Size: 66.6 x 59.9 x 4.0 mm. Some connoisseurs believe that this kind of tsuba was in mass production at the time. Small animal believed to be a fox, however some attribute it to a long-tailed rabbit or a squirrel. I am leaning towards the rabbit. Similar example is found at Robert E. Haynes Catalog №3, April 9-11, 1982 on page 11, under № 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. The only difference betwen my tsuba and his is that his has a square hole on the right shoulder of the seppa-dai. Early Muromachi (if we follow Robert it is even Nanbokucho, 1337-1392) or Momoyama period. The Momoyama attribution is mostly based on a fact that “waves and rabbit” motif became most popular in Momoyama times. Mokkōgata tsuba of similar design in this collection - see TSU-0282.

  • 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:

  • The thin iron plate of round form and black colour carved in sukidashi-bori with the design of rocks, waves, bridge, mountain pavilion and 5-storey pagoda under the moon, on both sides, alluding to Todai-ji temple in Nara. Slightly rounded rectangular hitsu-ana probably pierced later. Very narrow raised rim as usual in katsushi tsuba. In a modern wooden box.

  • Iron tsuba of round form with design of diamond-shaped family crest (waribishi-mon) in openwork (sukashi). Bevelled, raised rim. Kozuka-hitsu-ana plugged with tin or lead. Ko-Katchushi school. Early Muromachi period: Early 15th century (Oei era). Size: Height: 89.3 mm. Width: 89.0 mm. Rim thickness: 4.3 mm. Center thickness: 2.9 mm. Provenance: Sasano Masayuki Collection, № 41: "In this tsuba, a family crest incorporating four lozenges sits upright on the right side of the nakago-ana. The straight lines of the lozenge add substance and power. Initially, the crest creates confusion regarding the age, yet the overall impression is one lacking in vigor and probably dates rather later than Nanbokucho period".  
  • Iron tsuba of round form decorated with a design of bracken scrolls and paulownia leaves and blossoms (kiri-mon) in openwork (sukashi). Details carved in kebori. Squared rim with iron bones (tekkotsu). Hitsu-ana plugged with shakudō.

    Unsigned.

    Muromachi period, ca. 16th century.

  • 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.

Two lower round openings may also serve as udenuki-ana. Copper sekigane. Unsigned. Late Muromachi or Momoyama period, 16th century. Diameter: 90.4 x 89.8 x 2.8 mm.
  • Two ymagane tsuba (daisho) with chiseled diaper pattern of waves. The larger tsuba (dai) is of mokkō form with a wide (4.6 mm) polished rim (fukurin?). Water spray is realized in copper ten-zōgan. Size: 75.0 x 71.6  x 3.2 (center), 4.0 (rim) mm. Copper sekigane. The smaller tsuba (sho) is of oval form, without a rim. No inlay. Size: 53.2 x 45.5 x 4.1 mm. Ko-kinko school. Muromachi period. In Kokusai Tosogu Kai; 5th International Convention & Exhibition, 2009 on page 51 under № 5-U8 there is a piece from George Gaucys collection, described as follows: Unsigned Tachi-Kanagushi tsuba, Yamagane base. Nami (wave) motif. Circa: Muromachi period (15th century). 6.88 x 6.81 x 0.45 (rim), 0.36 (center). The classic wave form is typically seen in Muromachi period tosogu. The patina is rich and rustic, which presents history and warmth. This tsuba may be interpreted as either tachi-kanagushi or ko-kinko work. Early tachi tsuba were symmetrical in design and also not very sophisticated, Design elements filled in up to seppadai as the waves do in this tsuba. There is a simple fikurin of the same metal and it is flat to the plate. On the ko-kinko side, the crests of the waves show more complexity than tachi works and less symmetry. A very intriguing tsuba from late Muromachi period."

  • 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”!].

  • 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.

Lobes are decorated with landscape motifs in low relief carving (sukidashi-bori). On the obverse: A hut under a full moon, Shinto shrine gates (torii) with pines and a full moon, rocks, a large pine tree, and a temple (pagoda) surrounded by rocks and waves. On the reverse: waves, fishing boat, wild gees in flight under full moon, maple, hexagon (tortoiseshell, kikko) with a dot inside and a dot outside (inclusion/exclusion symbol), and chrysanthemum (the last two may be family crests, mon).

    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.
  • Thin iron plate of round form and black color carved in sukidashi-bori with design of rocks, waves, clouds, temple gates (torii), mountain pavilion and 5-storey pagoda on both sides, alluding to Todai-ji temple in Nara. Hitsu-ana pierced later. Very narrow very slightly raised rim. Copper sekigane.

  • Iron tsuba of slightly elongated round form decorated with design of melon flowers, vines, and leaves in brass flat inlay (hira-zōgan) on both sides. Slightly raised rim (mimi) carved in a way to simulate ring-shaped covering (fukurin). Kozuka hitsu-ana and kogai hitsu-ana both plugged with soft metal (tim or lead). Copper sekigane.

Note on design: though this design resembles family crests with oak and mulberry leaves, I believe it's  a melon flower [see Jeanne Allen. Designer's guide to Samurai Patterns. Chronicle Books, San Francisco, 1990, page 114, №130 "Melon Flowers":

    Note about the distribution of thickness (niku-oki): "this tsuba has toroid features, niku raises from the rim towards the centre but thins once more out when approaching the seppa-dai" [M. Sesko, "Handbook...", p. 48].
  • An iron tsuba of 12-lobed form with alternating four solid and four openwork areas, each with a central bar. Symbolism remains unclear, possibly - a gunbai, i.e. military leader's fan. The solid parts decorated with 5 to 6 rows of brass dots of nail heads inlaid in ten-zōgan. The center of the plate as well as the sukashi elements are outlined with brass wire. The kozuka-hitsu-ana seems original. Muromachi period. Dimensions: 77.9 x 77.5 x 3.2 mm.

Seppa-dai and hitsu-ana outlined with brass wire. Late Muromachi period (Ca. 1514-1573). Ōnin school. Unsigned. Dimensions (mm): 80.4 x 79.8 x 3.6 (center) 3.2 (rim). Similar tsuba in this collection: TSU-0374.2018
  • Iron tsuba of round form with design of  hatchet, snowflake, and triple diamond in openwork (ko-sukashi), and inlaid with five concentric circles of brass dots (ten-zōgan) and brass inner circular line. Sukashi elements outlined in brass.

    Late Muromachi period. Diameter: 82.4 mm; Thickness: 3.0 mm The triple lozenge (or diamond) is similar to the one on TSU-305 from Sasano Collection # 15. Very old motif; as Sasano remarks in his book "...represents the unstable political situation at the time".

    Kokusai Tosogu Kai 5th International Convention & Exhibition, October 28-30, 2009 at NEZU Museum, Tokyo, Japan, on page 83 provides the following explanation of the triple diamond symbol: "The pine bark is the form of the Diamonds, "Bishi", mon, seen from Nara period, found on cloth stored in the Shoso In, and used primarily by the Takeda family. The form of Bishi mon [similar to ours] is called "Chu Kage Matsukawa Bishi", (Middle Shaded Pine Bark Diamond)."

    A combination of hatchet (usually an axe) and a triple diamond (Matsukawabishi) alludes to the Nō play Hachi-no-ki (ref: Iron tsuba.

  • 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.

    TSU-0323. Ko-kinko yamagane tsuba with waves and rabbit motif.

  • Iron tsuba of slightly elongated round form decorated with three pairs of snowflake-form small perforations (ko-sukashi), each outlined with brass wire; five concentric circular rows of dots inlaid in brass or copper ten-zōgan (some dots are missing). Hitsu-ana of oval form. Ōnin school. Unsigned. Late Muromachi period. Dimensions: 75.6 mm x74.6 mm x 3.0 mm. Weight: 78.0 g. Old NBTHK certificate (green paper): Tokubetsu Kicho - "Extraordinary Work". Unlike most Ōnin ten-zōgan tsuba this one does not have circular brass wire inlay inside the dots area; neither it has brass trim around seppa-dai or hitsu-ana.  
  • Iron tsuba of mokkō form decorated with inome (wild boar's eye) in openwork (sukashi) outlined with brass wire. The plate decorated with 3 concentric circular rows of brass dots in ten-zōgan.

    Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: 72.1 x 71.3 x 2.3 mm.
  • Iron tsuba of round form with design of military commander's fan (gunbai) in openwork (sukashi). Square rim. Hitsu-ana plugged with lead or tin. Ko-tosho school. Mid Muromachi period. Late 15th century: Entoku era [1489-92] / Meio era [1489-1501]. Height: 80.3 mm, Width: 81.5 mm, Rim thickness: 3.0 mm. Centre thickness: 3.5 mm. Provenance: Sasano Masayuki Collection,  №23 in Japanese Sword Guard Masterpieces from the Sasano Collection, 1994: Ko-tosho. Sukashi design: Military commander's fan (gunbai). Mid Muromachi period. Late 15th century (Entoku / Meio era). The military commander's fan (gunbai) was cherished by samurai warriors. This tsuba is relatively thick, with the large fan nicely positioned on the plate.
  • Iron tsuba of four-lobbed mokkō form (possibly it was circular and then altered to produce the mokkō) with slightly raised rim decorated with three kukurizaru ('tied up monkey' toy) in openwork (sukashi) next to kogai-hitsu-ana; inlaid in red-ish copper (suaka) with the design of bamboo stems and leaves, and shapeless masses which most probably represent snow. Kozuka-hitsu-ana plugged with shakudo. Probably original kogai-hitsu-ana. Copper sekigane. Surface still covered with lacquer (urushi). Late Muromachi period (1514-1573). Size: 86.1 x 85.8 x 2.6 mm NBTHK Certificate №4002543: Hozon - "Worthy of preservation" (Attribution: Mumei Heianjō Zōgan)
  • 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.

  • Iron tsuba of round form with design of iris and snowflake in openwork (ko-sukashi or small cut-outs) outlined with brass wire. Three concentric rows of brass dots (ten-zōgan), with a brass circular line inside the innermost row of dots (missing on the back). Hitsu-ana is not outlined with brass wire, which let us suppose that it was cut out at a later date. Iron and brass. Ko-sukashi and ten-zōgan technique. Mid Muromachi period (1454-1513). Height: 74.0 mm, Width: 73.6 mm, Thickness: 3.0 mm.

    NBTHK certification of 1968: "Kicho". Condition is relatively poor: rust, missing inlay, scratches.

    While representation of the snowflake is rather standard, the meaning of the other cut-out design was initially less clear. Similar symbol was found at (1) "Kokusai Tosogu Kai, International Convention & Exhibition, September 24-25, 2005, The Frazier Historical Arms Museum, Louisville, Kentucky, USA"; on page 21 there is a photograph J-6 of a ko-tosho tsuba with "iris theme openwork"; (2) Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections. Sotheby's, London, Thursday 10 April 1997; page 11, lot 6 - a ko-katchushi tsuba of early Muromachi period fith "simple design of stylized iris". In both sources the symbol is explained as 'iris" (kakitsubata).

  • 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...    
  • The chrysanthemoid (kiku-gata) iron plate with polished surface decorated with arabesque (karakusa) and paulownia (kiri) leaves and flowers in brass, copper and silver flush inlay (hira-zōgan) on both sides. Some of the inlay goes over the edge. Kozuka- and kogai-hitsu-ana are filled with lead plugs. Sekigane of copper. Chrysanthemum and paulownia are the symbols of imperial family. The face is signed: Izumi no Kami to the right of nakago-ana, and Yoshiro on the left; the back is signed Koike Naomasa. His signed work is considered by many experts to have been made-to-order only. The original wooden box (tomobako) with inscription (hakogaki) signed by Dr. Kazutaro Torigoye and dated Showa 39 (1964). The late Muromachi or Momoyama period, 16th century. Dimensions: 89 mm x 84 mm x 3.6 mm; Weight: 170 g. Hakogaki lid: Yoshirō  kikka-gata Hakogaki lid inside: Iron, signed on the omote: Izumi no Kami – Yoshirō; on the ura: Koike Naomasa. Kikka-gata, pronounced maru-mumi, two hitsu-ana, karakusa, and kiri design in brass, silver, and suaka hira-zōgan. Height 8.5 cm, thickness 3.5 mm. Herewith I judge this work as authentic. On a lucky day in July of 1964. Torigoe Kōdō [Kazutarō] + kaō According to Robert Haynes [Catalog #7, 1983; №32, page 42-43] "This full form of the signature is seen very rarely". His example, illustrated in that catalogue, measures: height = 86 mm, thickness at seppa-dai = 3.75 mm and signed Izumi no Kami Yoshiro on the back and Koike Naomasa on the face. The further description of his specimen by Robert Haynes:
    "Early signed example of the work of Koike Naomasa. The kiku shape iron plate is well finished. The flush inlay is brass, for the scroll work on both sides, with the leaves and kiri mon in brass, copper and silver with strong detail carving. Some of the inlay goes almost over the edge, which is goishi gata. The large hitsuana are plugged in lead with starburst kokuin surface design. [...]The face is signed in deep bold kanji: Koike Naomasa; the back is signed: Izumi no Kami, on the right and Yoshiro on the left. There are one or two small pieces of inlay missing. Sold by Sotheby London, Oct. 27, 1981, lot 368. Height = 86 mm, thickness (seppa-dai) = 3.75 mm, (edge) = 4 mm."
    Another similar example presented at: "Tsuba" by Günter Heckmann, 1995, №T55 — "Designation: Koike Naomasa. Mid Edo, end of the 17th century. Iron, hira-zogan in brass, copper, silver and shakudo, katakiri-bori. Tendrils and leaves. 87.0 x 78.0 x 4.0 mm." Reference: Japanische Schwertzierate by Lumir Jisl, 1967, page. 13. [SV: Actually, his tsuba is signed Izumi no Kami  Yoshiro on the back; and Koike Naomasa on the front, exactly as Robert Haynes's tsuba. Dating this tsuba Mid-Edo, 17th century may be considered a misattribution]. More details regarding the Yoshirō tsuba. 
  • 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.

    Ōnin school. Unsigned. Late Muromachi period, 16th century. Dimensions: 88.8 x 88.3 x 3.0 mm. As per Merrily Baird, two legends are usually associated with the image of tsurigane, a large, suspended Buddhist bell: one is that of Dojo Temple (Dojo-ji), and the other is of Benkei stealing the tsurigane of Miidera Temple. Interestingly, this type of bell (tsurigane) is not described as a family crest (mon), while suzu and hansho bells are.  
  • Iron tsuba of round form decorated with design of moon, stars, cloud, snowflake, gorintō, and Genji-mon in negative openwork (in-sukashi). Raised tubular rim (dote-mimi). Deep black patina, traces of lacquer. Naka-daka type of plate (thicker in center, getting thiner towards the rim). Visible gap between the rim and the plate. Dimensions: Height: 91.7 mm; Width: 90.8 mm; Thickness at seppa-dai: 2.5 mm, plate before rim: 2.2 mm, of the rim: 5.6 mm. At least Mid Muromachi period, 15th century, but possibly earlier. In 'Silver Book', commenting tsuba №34 Sasano writes: "The technique used to create the rim is the same used for the peak (koshimaki) of helmets (kabuto) during the Kamakura and Nanbokucho periods." On the other hand, the abundance of sukashi elements points towards later times, perhaps late Muromachi or even Momoyama period. "Gorintō is a grave stone composed of five pieces, piled on one the other, representing, from the bottom upward, earth, water, fire, wind, and heaven, respectively" [Nihon Tō Kōza, Volume VI, Part 1.  AFU, 1993, p. 6. / LIB-1554]. A romantic description of the piece may look like this: The air is scented (incense symbol); it's a graveyard, marked by gorintō; a winter (snowflake) evening or night (moon, stars); mist is rising from a ravine towards moon. I did not manage to find a katchūshi piece of this design, only a few Kamakura-bori tsuba:

    Japanese Sword Fittings. Collection of G.H. Naunton, Esq., by Henri L. Joly, - 1912; №9.

    While the upper tsuba is dated end of Muromachi, the lower is attributed to the 17th century - Momoyama or early Edo period, though the author put this attribution under question. Deciphering of the strangely shaped opening to the left of nakago-ana is sometimes "a conventional scroll", and sometimes - a fern or bracken. I think mine is a cloud or mist, but I don't have any material evidence proving this understanding and came to conclusion by context only. It may easily be a dinosaurs playing ball. The fact that this thing always accompanies the Genji-mon, or incense symbol, it may be a scent itself.
