• Iron tsuba of round form decorated with eight roundels – circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiselled in kebori, and with flat brass inlay (hira-zōgan) of vines or leaves all over the plate. Both hitsu-ana are trimmed with brass. Nakago-ana of trapezoidal form. A distinctive character of this tsuba is a mon at 12 hours, depicting paulownia, or Kiri-mon [桐紋] – a symbol of the Toyotomi clan, led by Toyotomi Hideyoshi (豊臣 秀吉, 1537 – 1598). Kiri-mon was also used as fuku-mon (alternative family crests) for the Imperial Family and Imperial Court. Another important emblem at 6 o’clock is the Katakura clan [片倉氏, Katakura-shi] family crest. Katakura Kagetsuna (片倉 景綱, 1557 – 1615), a retainer of Date Masamune (伊達 政宗, 1567 – 1636); Kagetsuna was operational in Hideyoshi’s Odawara campaign in 1590, which ultimately ended the unification of Japan. Unsigned but may be attributed to Koike Yoshirō Naomasa or his workshop (Yoshirō, orKaga-Yoshirō school). Dimensions: Diameter: 85.5 mm; Thickness at seppa-dai: 5.0 mm.

    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.
  • 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 round form adorned with the design of stars, wild geese, floating blossoms, leaves and tendrils realized in brass inlay. The inlay technique includes suemon-zōgan and ten-zōgan. Two smaller openings (hitsu-ana) surrounded by a scalloped brass border. The seppa-dai border inlay is missing, as well as a few other fragments of inlay on both sides. Sword cut at 12 o'clock on the reverse. A tsuba with a strong autumnal connotation, which once belonged to a great battle weapon. One of only three known jūyō Ōnin tsuba. Translation of the paper, issued by the Japanese sword fittings (tosogu) examination board: Designated as jūyō-tosogu at the 34th jūyō-shinsa held on April 14th 1988 Kaki-karimon zōgan-tsuba (花卉雁文象嵌鐔) — Tsuba with zōgan design of flowers and wild geese. Mumei: Onin (応仁) Tokyo. Nakasono Tokumi (中園とくみ) Measurements: height 9.5 cm, width 9.4 cm, thickness at rim 0.35 cm Interpretation: marugata, iron, brass zōgan, two hitsu-ana Time: end of Muromachi Explanation: Ōnin-tsuba are thin iron ita-tsuba which show a brass zōgan ornamentation. All of them are mumei and there is the theory that they were made in the Onin era (1467-1469) although today more and more the theory is accepted that they are in general late Muromachi period works. There are two kinds of brass zōgan interpretations: One depicts irregularly arranged tachibana branches, wild geese, chrysanthemums, flowers, or karakusa for example, and the other one shows punctual zōgan elements, which are referred to as hoshi-zōgan or ro-zōgan, and concentrical zōgan elements between the nakago-ana and the rim. The latter interpretations might also be accompanied by simple ko-sukashi in the form of butterflies, clouds, hats, or stylized mountains. This tsuba is a typical work from the former category. It is large and feels massive and the powerful and impressive zōgan and the excellent iron make it a highly tasteful piece.

All typical emblems with bellflower, two variations on suhama theme, and 3, 4, 5, and 6-poinitng mon variations. A distinctive character of this tsuba is a mon at 12 hours depicting water plantain (omodaka).

    “Omodaka was also called shōgunsō (victorious army grass); because of this martial connotation, it was a design favored for the crests of samurai families” [Family crests of Japan, Stone Bridge Press, Berkeley, California]. Yoshirō school (Kaga-Yoshirō). The Momoyama or early Edo period, beginning of 17th century. Size: Height: 81.4 mm; width: 81.2; thickness 3.8 mm at seppa-dai.
  • Iron tsuba of circular form with a branch of loquat (biwa) pierced in positive silhouette (ji-sukashi) and carved in marubori technique (marubori-sukashi). Kozuka and kogai hitsu-ana are plugged with shakudo.

    Signature: Choshu Kawaji ju Hisatsugu saku. Chōshū school in Nagato province.

    According to M. Sesko 'Genealogies' Hisatsugu was a 4th generation Kawaji School master from Chōshū (present day Nagato), with the name Gonbei, formerly Toramatsu, adopted son of Tomohisa (1687-1743) [page 117]. For Tomohisa work see TSU-0104 in this collection.
  • 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 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 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 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].
