Provenance: The second John Harding." Also at: JAPANESE SWORD-FITTINGS & METALWORK IN THE LUNDGREN COLLECTION. Published by Otsuka Kogeisha, Tokyo 1992. № 134. Description on page 173: Sword guard with design of shrimps in inlay (scarlet [sic] maple leaves and deer on the reverse side). Unsigned. Heianjō inlay school. Vertical 6.85 cm, horizontal 6.90 cm, Th. of rim 0.40 cm. Iron. Taka-bori relief and brass inlay. Momoyama period, 16th - 17th century. According to Merrily Baird, maple leaves, especially if paired with the deer, allude to autumnal tradition of Japanese aristocracy of viewing the seasonal changes of color in the Nara area. The lobster is typical Japanese ebi, - it lacks prominent claws, and has a spiny shell. As a symbol of longevity and good fortune, lobster is a staple of New Year's decoration.

Iron tsuba of round form pierced with design of paulownia (kiri) in a circle in positive silhouette (ji-sukashi), details carved in low relief (sukidashi-bori). Hitsu-ana were cut later and then both plugged with lead or pewter. Brown patina. The most unusual characteristic of this tsuba is its 'positiveness': the absolute majority of Kamakura-bori tsuba are of ko-sukashi type, i.e. with small openings, presenting the motif in negative silhouette. Kamakura-bori school. Muromachi period (ca. 1450). Size: Height: 85.1 mm, width: 84.8 mm, thickness at seppa-dai: 3.2 mm, at rim: 2.8 mm. Weight: 79.1 g. A similar tsuba is presented at Japanese Swords and Sword Fittings from the Collection of Dr. Walter Ames Compton. Part I. Christie's, New York, March 31, 1992, page 11, №3: "A Kamakura-bori tsuba. Muromachi period, ca. 1450. The round iron plate is pierced with an openwork design of a paulownia crest (kiri-mon), the surface details of which are carved in low relief. The design is repeated on the reverse. The edge is slightly raised  and the rim has some iron bones. 78 mm x 77 mm x 3.5 mm. Hakogaki by Sato Kanzan, dated summer 1973."

Iron tsuba of round form decorated with two boar's eyes (inome) and two dragonflies (tombo) in small openwork (ko-sukashi) outlined with brass wire. The plate also decorated with 2 to 5 concentric circular rows of brass dots (nail heads) in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire. The inlaid metal is of red-ish hue, so it may be copper, and not brass. The surface has remnants of lacquer. Ōnin school. Mid Muromachi period, middle of 15th century. Dimensions: Diameter: 90 mm, thickness: 3.2 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13]. Two other cutouts - in the form of what in European tradition symbolizes the heart, on the top and in the bottom of tsuba disc - may have two different explanations. The most usual one, inome - "Heart-shaped pattern, which is said to go back to the shape of a wild boar's eye" [Markus Sesko. Encyclopedia of Japanese Swords. Print and publishing: Lulu Enterprises, Inc., 2014.]. This understanding is shared by Robert Haynes [Robert E. Haynes. Study Collection of Japanese  Sword Fittings. Nihon Art Publishers, 2010.] and elsewhere, with an exception of Okabe-Kakuya [Okabe-Kakuya. JAPANESE SWORD GUARDS. Museum of Fine Arts, Boston. In cooperation with the department of Chinese and Japanese art; - 1908, p. 14], who provides the illustration of inome-shaped cut-outs with the following explanation: " The tsuba shown in Fig. 13 approaches a square form with rounded corners and is perforated with Aoi decoration. But this book was written long time ago, when people even at MFA might not know enough... The same interpretation of the said heart-like symbol (aoi leaf) is given at Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p. 54: "This mokkō-formed tsuba recalls the aoi form, perforated as it is with the four aoi leaves." It is possible that the "wild boar's eye" theory was developed by later scholars.   There is also a theory, supported by Graham Gemmell, saying that: “In simple terms Onin works are decorated Ko-Katchushi tsuba. … But, not content with iron alone, they began to decorate it with what was, in the early Muromachi period, a rare and valuable metal, brass. The Onin workers cut the design into the iron, using narrow channels, cast the brass, piece by piece, and then hammered it into the iron plate as though they were putting together a jigsaw. When complete the tsuba would be black lacquered exactly as the plain iron ones had been, the brass shining dully through it in a way that fulfilled the goal of shibui or restrained elegance.” [Tosogu. Treasure of the samurai. Fine Japanese Sword Fittings from The Muromachi to The Meiji Period, by Graham Gemmell. // Sarzi-Amadè Limited, London, 1991. An exhibition held in London from 21st March to 4th April, 1991]. The following illustration from Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; pp. 43 supports the idea. Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."  

Iron tsuba of round form decorated with design of pine tree mushrooms (matsutake) in openwork (sukashi). Hitsu-ana of elongated oval form. Raised rim (mimi) with iron bones (tekkotsu). Copper sekigane. Size: 84.5 mm x 85.1 mm; thickness: 3.0 mm (center), 5.6 mm (rim). Mid Muromachi period, 15th century. The shape and width of the rim, as well as the shape of the hitsu-ana, argue for earlier Muromachi. Tsuba is slightly wider than high, that might suggest middle of Muromachi age. According to Robert Haynes, circa 1450-1500.

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.

Late Muromachi period, 16th century. Dimensions: 81.1 x 79.5 x 3. mm (seppa-dai), 2.2 mm (base plate), 4.4. (rim).

The mountain pavilion and bridge carved in sunken relief on the iron tsuba – both part of Tōdai-ji, a temple in Nara – are detailed in fine kebori (line) engraving. As a result of the chiselling used to create the relief, the ground of the piece is relatively thin”. Also page 41 in Tsuba Kanshoki. Kazutaro Torogoye, 1975 [LIB-1480.2018].

This tsuba is very much similar to TSU-0384.  

Kozuka with seven insects (fly, grasshopper, bee, butterfly, dragonfly, firefly, and cricket) and grass with dewdrops motif. Shakudō, flush gold inlay (hira-zōgan). 95.2 (H) x 13.7 mm (W). Mid Edo period (Late 17th - early 18th century, Genroku era 1688-1703). Unsigned. Kaga school. A look-a-like kozuka (with five insects) is illustrated at Japanese Sword Fittings.

Iron tsuba of round form with design of lattice (kōshi-mon, 格子文) cut in openwork (sukashi), with low relief shallow linear carving along the bars. Well forged plate with brown-ish hue. To the right of nakago-ana there is a clear inscription of the character Shō (正), which is explained by Markus Sesko is follows: "The Shinsa obviously recognized more from the signature when having the tsuba in hand, i.e. they were confident to say it is signed "Shōami" but the rest is illegible (ika-fumei, 以下不明). That is, if they were just able to read the first character SHŌ (正) and saw that there were two more, most likely A (阿) and MI (弥), they would have put those character in boxes on the paper. Boxes around characters namely means that the character is not 100% legible but it can be assumed what it is." Momoyama or early Edo period. Dimensions: 85.9 mm diameter, 3.6 mm thickness at seppa-dai. Weight: 79 g. NBTHK certificate № 425069 with attestation: Hozon - "Worthy of preservation". A similar tsuba is presented at Japanese Sword Fittings from the R. B. Caldwell Collection. Sale LN4188 "HIGO". Sotheby's, 30th March 1994, №15. The description says: "A rare early Kamakura-bori tsuba. Nambokucho period (late 14th century). Of circular form, the dark plate carved and pierced with a gate design, the struts with double engraved lines. Unsigned. 8.5 cm." The lot was sold for 1,840 GBP. We have two possible explanations of the discrepancy between Sotheby's and Shinsa/Sesko attribution: 1) either Sotheby's or Shinsa/Sesko were wrong in their attribution or 2) these are two different pieces, one - Kamakura-bori from the 14th century and another - Shōami from 16th/17th century. Anyway, I would consider my piece as a Shōami tsuba of Momoyama - early Edo period, just for the sake of modesty.    

Iron tsuba of mokko form decorated with trellis, vines, foliage, and gourds inlaid in brass with details carved in low relief.

NBTHK: Tokubetsu Hozon №2003186.

Momoyama period (1574 – 1603). Dimensions: H: 85.5 cm, W: 79 mm, Thickness (centre): 4.8 mm. Tsuba of a similar design can be found in this collection [TSU-0373]. In that example, the plate was later pierced with geometrical mon-like openwork to resemble Koike Yoshirō's handguards. More about this type of tsuba here.

Shingen school (or style) tsuba of round form with an iron core of spoked-wheel shape, with its centre covered with a copper plate decorated with star-shaped punch marks. From this copper plate outward, the body is formed by brass and copper wire (flat and twisted) in a weave pattern. Both hitsu-ana are outlined in brass with a raised rim. Copper sekigane. Unsigned. Edo period, 18th century. SOLD   Height: 98.0 mm, Width: 97.4 mm, Thickness at seppa-dai: 6.0 mm. Weight: 290 g. NBTHK certificate №436696: 'Hozon' attestation. Citing "JAPANESE SWORD-MOUNTS IN THE COLLECTIONS OF FIELD MUSEUM" by Helen C. Gunsaulus, Assistant Curator of Japanese Ethnology. 61 plates. Berthold Laufer, Curator of Anthropology. Field Museum of Natural History, Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p.45: "An unusual group of tsuba popular in the late sixteenth century and afterwards is made up of those guards known as Shingen tsuba, a name which was derived from a sixteenth-century warrior, Takeda Shingen (Takeda Harunobu, 1521-73), who is said to have preferred this style of guard, as it combined strength and lightness. Under the category of "Shingen", four different types abd generally listed, though a fifth appears in the drawings in the Boston Catalogue of Okabe Kakuya "Japanese Sword Guards" (p. 21). It is square, that form which is said to have been used in Ashikaga days for scaling walls, the sword having been set up as a step. [...] The following descriptions include, however, the Shingen tsuba usually met with.

1. So-called Mukade ("centipede") tsuba are made of iron in which a centepede is inlaid in brass or copper wire. Mukade tsuba of Myōchin and Umetada warkmanship have been found with the inscription, "Made to the taste of Takeda Shingen".
2. There are those of solid iron, with need centers of brass, to the edges of which is affixed a weaving of brass and copper wires which is bound to the foundation disk by a rim, usually decorated simply.
3. Another type is of solid iron, bored at intervals and laced with braided or twisted wires of copper and brass.
4. The fourth type is a chrysanthemoid form, chiselled in open work and laced or woven tightly with copper and brass wire."

I believe that my tsuba [№ TSU-0338] belongs to the fourth type. However, this particular specimen does not conform with the description of Shingen tsuba as combining strength and lightness. Its weight is 290 g, which tells us that most probably it had purely decorative function (as most tsuba in Edo period). A somewhat similar design can be found at wikimedia. A look-a-like tsuba is illustrated at Compton Collection, Part II, p.p. 26-27, №54. It is dated ca. 1700. It was in a box with Sato Kanzan inscription, and had NBTHK certificate attesttion of 'Tokubetsu Kicho'. Price realized: $5,280.

Iron tsuba of round form decorated with design of sea waves in low relief carving (kebori) and pierced with design of cherry blossom in negative silhouette (in-sukashi) and water wheel in positive silhouette (ji-sukashi). The solid portion of the plate has a shallow groove just before the edge. Copper sekigane. School attribution is unclear. Unsigned. Momoyama period, 16th - 17th century. Dimensions: Height: 70.3 mm, width: 71.1 mm, thickness at seppa-dai: 4.4 mm, at rim 4.1 mm. Provenance: Robert E. Haynes, Mark Weisman. This is what shibuiswords.com says about this tsuba:

"A very unusual iron plate tsuba. The solid plate is carved with waves on both sides. A cherry bloom in sukashi, lower left, and the right third of the plate in openwork with design of a water wheel. The rim with some iron bones. The hitsu-ana is original but the shape may have been slightly changed. One would expect this to be the work of the early Edo period, but the age of the walls of the sukashi would suggest that this is a work of the middle Muromachi period. This must be the forerunner for the Edo examples we see of this type of design." (Haynes)

I managed to find a look-a-like tsuba in Haynes Catalog #5, 1983, pp. 20-21, №44: "Typical later Heianjo brass inlay example. Ca. 1725. Ht. 7 cm., Th. 4.5 mm., $100/200". We see that the  plate design of both tsuba is the same, and the only difference is the trim. It would be logical to assume that both pieces were made at about the same time, rather than 225 years apart. To be fair, let's accept that they were made in Momoyama period.

Kozuka made of pure copper with Daruma motif. The engraving technique is known as katakibori ("half-cut carving"). Signed on the back: Yasuchika. Size: 96.5 (H) x 14.5 mm (W). Edo period (Late 18th century). The technique of Katakiribori was developed by  Yokoya school of artisans. Detailed account of Yasuchika family of kodōgo carvers is given at Japanese Sword Fittings from the Alexander G. Mosle Collection; Sebastian Izzard LLC, 2004 on page 64. The article ends with the following statement: "Given the popularity of his style and his many students, it is not surprising that a number of works bearing Yasuchika's signature are today disputed." S. Izzard attributes Yasuchika masters to Nara school. Yasuchika-signed kozuka in Important Japanese Swords and Sword Furniture and Works of Art [November 5, 1980, sales "Kotetsu". New York, Christie, Manson & Woods International Inc., 1980, pp.92-93, lot 172 and 173] are stylistically very different to our example. A shibuichi katakiribori kozuka, bearing the signature of Yashuchika, is illustrated at The Hartman Collection of Japanese Metalwork [sold at auction by Christie, Manson & Woods Ltd. June 30 and July 1, London, 1976] on page 82, lot 291. It depicts Daikoku and stylistically similar to ours. The description on page 83 says: "signed Yasuchika, and inscribed "drawn by Hanabusa Itcho" (Yasuchika IV, school of Iawamoto konkan, circa 1800)". A detailed account of Yasuchika signatures is presented at Masterpiece tsuba and kodogu from the Hans Conried and Alexander G. Mosle collections. Important woodblock prints by Utamaro, Hokusai, Hiroshige, Yoshida and other masters. San Francisco, September 1-25, 1983. Catalog #7. Robert E. Haynes, Ltd., pp. 141-174. The example that looks like ours is on page 146: Though we have to admit that the example from Catalog #7 by Robert E. Haynes looks much stronger.
