• Iron tsuba of oval form with design of  a gourd or aubergine vine with fruits, leaves, and blossoms climbing a trellis, and a fence in yellow brass and red copper flat inlay (hira-zōgan); inlay engraved. Two latticed windows represented by openwork (sukashi). The iron web has deep black patina. The seller attributes this tsuba to Heianjo-Namban school, whatever it means. Momoyama or early Edo period, 17th century. Kaga or Heianjō School. Unsigned. Height: 77.3, Width: 73.1, Thickness at seppa-dai: 3.6 mm.
  • 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 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. Heianjō or Kaga School. Muromachi or Momoyama period, 16th century. Iron, hira-zōgan brass inlay. Round (maru gata) form, diameter 79 mm. Size: 80.3 x 78.4 mm; thickness at seppa-dai: 3.4 mm; at the middle: 3.8 mm; before the rim: 2.4 mm, rim: 2.8 mm. 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":

    Jeanne Allen. Designer's guide to Samurai Patterns. Chronicle Books, San Francisco, 1990. Page 114, №130.

    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].
  • Iron tsuba of round form decorated with eight roundels – circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiseled in kebori, and with flat brass inlay (hira-zōgan) of vines or leaves all over the plate. Both hitsu-ana trimmed in brass. Nakago-ana of rectangular form, with copper sekigane. Four positive openwork (ji-sukashi) roundels at 12, 3, 6, and 9 o'clock; and four negative openwork (in-sukashi) roundels with cherry blossom, bellflower, and two variations on suhama theme. Yoshirō school (Kaga-Yoshirō). The Momoyama or early Edo period, late 16th to early 17th century. Size: diameter 81.4 mm, thickness 4.7 mmat seppa-dai, 4.0 mm at rim. Christie's lot description: AN IRON TSUBA; EDO PERIOD (17TH CENTURY). THE DOLPHYN COLLECTION OF SAMURAI ART. The round iron tsuba pierced with roundels of various floral motifs interspersed among scrolling foliage, all inlaid with brass. 8.1 cm. high. Provenance: Pabst Collection (no. 338).
  • Iron tsuba of round form decorated with eight circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiseled in kebori, as well as with flat brass inlay (hira-zōgan) of vines, leaves, and flowers all over the plate. Yoshirō school (Kaga-Yoshirō). The Momoyama or early Edo period, 17th century. Size: diameter 80 mm, thickness at seppa-dai 3,6 mm. Symbols: [12:00 o'clock] - Wood sorrel (katabami) and swords ; [9:00] - Cherry blossom (sakura); [7:30] - Bellflower (kikyō), kamon of Toki clan; [3:00] - possibly, a six-petal Chrysanthemum (kiku) or a Passion flower (tessen); [1:30] - Hemp (asanoha). The symbols at 6:00, 10:30, and 4:30 o'clock seem to be geometrical patterns of auspicious meaning: a cross in a square, a four pointing star, and a diamond, respectively. Alternatively, we may look at this piece as purely decorative, with patterns at 12:00, 3:00, 6:00, and 9:00 o'clock in negative openwork (in-sukashi), and at 1:30, 4:40, 7:20, and 10:30 o'clock - in positive openwork (ji-sukashi, or yō-sukashi). Markus Sesko in his Handbook of sword fittings related terms [Herstellung und Verlag: Books on Demand GmbH, Norderstedt, 2011] discriminates this type of openwork in a separate class: Ranma-sukashi: "This term is applied to circular sukashi with family crests to their inside, which are arranged running along the rim area. The description goes back to the opened boards (ranma) between the sliding doors and the ceiling of Japanese rooms. Ranma-sukashi are mostly seen on old Heianjō- or Yoshirō-zōgan-tsuba but also on works of Hayashi Matashichi" [page 30].
  • 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..."  
  • Kyo-sukashi iron tsuba of round form with design of hollyhock (aoi ) and wild geese. Slightly rounded rim. Copper sekigane. Momoyama period, late 16th - early 17th century. Height: 82.6 mm, Width: 82.1 mm, Thickness at seppa-dai: 4.5 mm. NTHK (Nihon Token Hozon Kai) certified.  
  • Iron tsuba with design of a cricket and grass inlaid in brass (suemon-zōgan) and a bridge over a stream in openwork (sukashi) on both sides. Inlay of distant part of the cricket's antenna is missing. Heianjō School. Momoyama period. Diameter: 79.5 mm, thickness at seppa-dai: 3.3 mm NBTHK # 4002100.
  • Iron tsuba of 8-lobed form pierced with six openings (sukashi) and decorated with design of bamboo and arabesque in flat brass inlay (hira-zōgan). Two of the openings serve as hitsu-ana. The design on the face represents bamboo trunks and leaves, clouds, waves, and vines; on the back - vines and leaves, that forms an arabesque (karakusa) motif. Rounded square rim. 'Silver' patina. Hitsu-ana with copper sekigane. Heianjō (most probable) or Kaga-Yoshirō school. Late Muromachi or Momoyama period; 16th century. Size: Height: 74.6 mm; Width: 69.5 mm; Thickness at seppa-dai: 4.2 mm. Weight: 113.9 g. Provenance: Gary D. Murtha. This tsuba is illustrated at: Japanese sword guards. Onin - Heianjo - Yoshiro by Gary D. Murtha [GDM Publications, 2016, p. 48]: "Iron, 80x75x3 mm tsuba with brass karakusa vines and leaves on one side with bamboo, leaves, and clouds on the reverse. This tsuba is one of those pieces that might be classified as Onin or Heianjo work, but the flush inlay tips it to the Heianjo side. Late Muromachi period." I would like to add that it easily may also be classified as Kaga-Yoshirō. Robert Haynes in Study Collection.., page 32, illustrates a look-a-like example, and writes: "This style of inlay, where the designs on the face and the back are very different, was common to the work of artists in Kyoto in the Momoyama period."
  • Iron tsuba of round form with two ebi (lobster) on omote (obverse side) and shika (deer) among scattered momiji (maple leaves) on ura (reverse side) motif in brass takabori (high relief) suemon-zōgan. Traces of lacquer. Unsigned. Late Muromachi / Momoyama period (late 16th / Early 17th century). Dimensions: 69.0.6 mm (H) x 69.6 mm (W) x 3.4 mm (T, seppa-dai). Weight: 92.6 g.

Description at Christie's: "The iron plate depicting two lobsters in takabory and brass takazogan, the reverse similarly decorated with deer among scattered maple leaves, square mimi, late Muromachi / early Momoyama period (late 16th/early 17th century) Diameter 68 mm, mimi thickness 4 mm. 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.
  • Well-forged iron plate of round shape (maru-gata) is decorated with water weeds or arabesque (karakusa) in flat brass inlay (hira-zōgan) all over and eight family crests (mon) of round form in cast brass with delicate linear carving (kebori) and openwork (sukashi). Crests represent: [at 9 hours] three counter-clockwise commas or swirls (tomoe); [at 10:30] plum blossom (ume); [at 12:00, 1:130, and 7:30] - stylized flower made by cutting out five suhama symblos (flower-shaped suhama); [at 3:00] bellflower (kikyō); [at 4:30] seven-star crest (shichiyō-mon); [at 6:00] cherry blossom (sakura). Brass-trimmed ryo-hitsu. Copper sekigane. Yoshirō school. Momoyama or early Edo period, end of the 16th to first half of the 17th century (1574-1650). Inscription on seppa-dai: 八幡 - Hachiman. Size: height 89.6 mm, width 89.3 mm, thickness at seppa-dai 3,0 mm. Weight 129.7 g. NBTHK certificate № 4007685, June 27, 2015: HOZON (Worthy of Preservation). As for the inscription, Nihonto Message Board blog discussion provides the following explanation of the inscription: "An expression of conviction as to being the best under the sun". On the other hand, there may be more in this confluence of symbols: the tomoe crest at 9:00 is "the kamon of Hachiman, the war god" [Family Crests of Japan; Stone Bridge Press, Berkeley, CA, 2007, p. 108]. The character 八 in the inscription cut stronger than the other kanji, and may be by a different hand in different time. 八 (hachi, eight): "The numeral eight was appreciated because its shape broadens toward the bottom, symbolizing eternal expansion" [ibid, p. 119]. It may be said that this tsuba is dedicated to Hachiman. Other crests (suhama, bellflower, seven-stars, plum and cherry blossoms) collectively allude to "good old times" when Fijiwara and Taira clans were in full bloom. Markus Sesko believes that the inscriptions reads: Hachiman: "the inscription is/was HACHIMAN (八幡), the God of War and a relatively popular inscription for tsuba, swords and armor." Elliott Long and Robert Haynes provide the following explanation of the inscription: "...hachi is correct and represents the name of the HACHI SHRINE. The inscription reads 'YAWATA' which is the name of the mountain in Mino Province where the HACHI Shrine is located". Details on Hachiman Shrine in Yawata (八幡市) can be found elsewhere, including Historical and geographical dictionary of Japan by Edmond Papinot. Van Ham auction house provides the following description: MON-SUKASHI TSUBA. MARUGATA. Japan. Momoyama period. Yoshiro school. Iron with inlays of brass.

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."

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 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).

    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.    
  • A yamagane tsuba of oval form with green-ish black patina decorated in usuniku-bori carving and gold iroe with wisteria (fuji) motif plus nanako-ji ground on both sides. Kozuka-hitsu-ana possibly cut later.

    Momoyama or may be even Muromachi period. Dimensions: 70.0 x 61.2 x 5.0 (center) mm
  • Relatively thick iron tsuba of rounded square form with slightly elevated rim decorated in carving (sukidashi-bori) and yellow brass (shinchū) inlay (suemon-zōgan) with legendary creatures (humans with cow heads) in a pine tree forrest on the face,  and a horned man with a stick hunting a rabbit in the woods on the reverse.  Large hitsu-ana possibly cut off later on. In the beginning of the 20th century such tsuba were usually attributed to Fushimi-Kaga school. This one may be attributed to either Ōnin or to Heianjō. The latter seems most plosible because of the thick web and dull patina. The technique may also be called "shinchū-zōgan". Momoyama or early Edo period. Unsigned. Dimensions: 72.3 x 68.4 x 4.1 mm
  • Iron tsuba of round form with dam-shaped rim (dote-mimi) pierced with hitsu-ana and two udenuki-ana (probably cut later on) decorated in flat inlay (hira-zōgan) with vines and symbols of thunder or lightning (possibly - family crest, mon). Hitsu-ana and nakago-ana with copper sekigane.

    Ōnin or Heianjō school, or, possibly Kaga or Umetada school. Momoyama period or earlier (Muromachi), 16th century. Unsigned.

  • Iron tsuba of mokko form decorated with brass flat inlay (hira-zōgan) all over on both sits and going over the rounded rim. Black patina, well-forged iron. Hitsu-ana outlined with brass inlay. Former owner's catalogue number in red paint reads 25-17-61. Gary D. Murtha provides detailed account of this type of tsuba in Japanese Sword Guards. Onin-Heianjo-Yoshiro book on pages 118-122. He calls this type of tsuba "Heianjo Mogusa Tsuba": "The term mogusa is commonly used for an inlay design that represents an aquatic weed, similar to a duck weed or sago plant, which is known to quickly invade and overtake bodies of water. [...] Perhaps the visual image has some cross-over meaning for samurai in that, like the plant, a small aggressive samurai force could conquer a larger foe/area." I tried to find any reference to "mogusa" in literature, - to no avail. Neither on the vastness of internet, including Wikipedia... I did find the "duckweed" (one word), but visually it has nothing to do with the pattern on tsuba. "Sago plant" probably stands for 'Sago palm", and there is some very distant reminiscence in the construction of the sago palm leaf and the said design of inlay, but I would not go that far. In the old catalogues, such as Naunton and Hawkshaw collections, this pattern as called "sea weed" and/or "conventional fir". I will stick to these descriptions, tested by the time, and leave the enigmatic "mogusa" alone. Obviously, this type of tsuba has transformed into Yoshirō tsuba, both in Kaga province and Bizen province. Momoyama period (ca. 1660). Dimensions: 74.5 x 73.7 x 4.4 mm.
