Iron tsuba of round form decorated with dragonfly (tombo) and comma (comma-like swirl, tomoe) in openwork (sukashi) outlined with brass wire. The plate decorated with 5 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: Diameter: 89.5 mm, thickness: 3.1 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].   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 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:   While the upper tsuba is dated the 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 to prove this understanding, and I came to a conclusion based only on context. It may easily be dinosaurs playing ball. The fact that this thing always accompanies the Genji-mon, or incense symbol, it may be a scent itself.

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."

Round iron plate of grey colour decorated in low relief (sukidashi-bori) on the face with sea waves (both layered waves, seigaiha, and rough waves, araumi), sago palm (cycas revoluta, sotetsu), presumably orchid leaves (ran) - five of them - hanging from the above, and  reeds (ashi), and on the back with waves (seigaiha only), rocks, chrysanthemums (kiku), clove (chori), reed, and presumably orchid leaves - three of them - hanging from the above. The kozuka-hitsu-ana was probably cut later. The plate is lacking the raised rim, typical for the kamakura-bori school. Muromachi period.  Dimensions: Height: 76.8 mm, width: 76.1 mm, Thickness at seppa-dai: 3.3 mm, at rim 2.0 mm. Height of nakago-ana: 29 mm. Weight: 82.4 g. NBTHK certificate № 402152: Hozon - "Worthy of preservation". A similar (most probably the same) tsuba is illustrated and described at Butterfield & Butterfield. IMPORTANT JAPANESE SWORDS, SWORD FITTINGS AND ARMOR. Auction Monday, November 19th, 1979. Sale # 3063 under lot № 66. It describes the piece as following: “Kamakura bori work of the Muromachi period. Round thin plate with some small iron bones in the edge. Carved with design of plants (sego palm) rocks, and waves on the face. The back has half of two chrysanthemums, waves, clove, and sego palm leaves. The kozuka-hitsu has been added and later enlarged. A good typical example without the rim most have. Diameter: 7.7 cm., thickness 2.5 mm. Estimated price $100-200":

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 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.

Published in Japan in 1994.

Iron tsuba of round form with a butterfly (left) and dragonfly (right) design in openwork (sukashi), outlined with brass wire. The thin plate is also decorated with five concentric circular rows of brass dots (nail heads) in ten-zōgan; brass wire outlines the centre of the plate. School: Ōnin ten-zogan. Late Muromachi period, 16th century. Diameter: 88 mm, thickness at seppa-dai: 3.1 mm. Another tsuba of similar design, Tōshō school, is illustrated in this collection; see TSU-0353.2018. The design is referenced in LIB-1359.2017 Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections, Sotheby's, London, Thursday, 10 April 1997; p. 18, item 37: "pierced with two large formalised butterflies..."

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."  

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.  

Iron tsuba of round form with design of two paper lanterns in openwork (small cut-outs, ko-sukashi ) outlined with brass wire. The plate is decorated with four concentric rows of brass dot inlay (ten-zōgan), with a brass circular wire inside the innermost row of dots (missing on the back). Hitsu-ana of rectangular form is not outlined with brass wire, which let us suppose that it was cut out at a later date. Copper sekigane. Mid Muromachi period (1454-1513). Diameter: 74.0 mm, thickness: 2.6 mm. Tsuba is illustrated at: 新版 日本刀講座 小道具鑑定編 本間 薫山 佐藤 寒山 : Shinhan Nihonto Koza, Volume VI, Kodogu Part 1. Under supervision of Honma Kunzan and Sato Kanzan. 鍔 無名 応仁 鉄地) 丸形 小透 槌目 真鍮据文 点象嵌 丸耳 : Tsuba with no signature, Ōnin style. Base metal iron (jigane), round shape, small perforations (ko-sukashi), hammering finish (tsuchime). Pre-cast brass inlay (shinchu suemon-zōgan); dot inlay (ten-zōgan); round edge (maru-mimi). English translation of the book indicated above Nihon Tō Kōza, Volume VI, Part 1 by Harry Afu Watson, AFU Research Enterprises, Inc., 1993. Tsuba in question illustrated on page 14 and described as follows: " Tsuba mumei Ōnin. Tetsu ji maru gata ko-sukashi tsuchime shitate shinchū suemon ten zogan maru mimi. Brass suemon". My question remains: why such a text is called 'translation' while it looks more like transliteration of romanization?
