• 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.
  • Iron tsuba of mokkō form (mokkōgata) pierced (sukashi) and inlaid with precast dark brass inlay (taka-zōgan) with somewhat abstract/geometrical design that can be liberally described as pines, mist, and snow.

    Momoyama or early Edo period. End of the 16th - beginning of the 17th century. Heianjō school. Unsigned. Dimensions: 86.8 x 82.9 x 4.5 mm.
  • 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 round form pierced (sukashi) in a chessboard fashion and decorated with linear (sen-zōgan) and cast (suemon-zōgan) brass inlay, including symbols of the swastika, flower-lozenge, maple leaf, pine needle, etc. on both sides; rim and openings outlined with brass inlay. Nakagō-ana plugged with copper fittings (sekigane).

    Momoyama period. End of the 16th - beginning of the 17th century. Dimensions: Diameter: 75.5; Thickness: 4.5 mm.  
  • Iron tsuba of otafuku-gata form decorated on the face with death and autumn motifs: autumnal grasses and flowers in yellow brass and shakudō, skull, limb bone and sternum inlaid in shakudō. On the reverse the plate is inlaid in red copper with a chrysanthemum and maple leaves floating in stylized water streams. "Plants floating atop water form common motifs, as occurs with chrysanthemums, maple leaves, and cherry blossoms, in particular." [Merrily Baird]. Such plants may be used as a family crest (mon), or may be just a reminder of a floating nature of life.   Momoyama period, late 15th century. Dimensions: 75.3 x 69.9 x 4.3 mm.
  • Iron tsuba of round form pierced (sukashi) and inlaid in flat (hira-zōgan) and cast brass (suemon-zōgan), details carved in kebori, with design of two phoenixes, bamboo, and paulownia leaves and flowers (kiri-mon) on both sides. According to seller: Bizen-Yoshirō school (or Heianjō school). Unsigned.

    Momoyama period. End of the 16th - beginning of the 17th century. Dimensions: Diameter: 99.5 mm; Thickness: 2.1 mm at centre; 4.3 mm at the rim. According to Merrily Baird (Symbols of Japan), "bamboo teamed with paulownia blossoms or with paulownia and the phoenix, in reference to the Chinese legend that the phoenix perches only on the paulownia and eats only the bamboo". Citation from http://www.clevelandart.org/art/1986.2.1: "The immense heraldic birds on display [...] reflect the Momoyama era's spirit of newly gained self-confidence and an affinity for grand expressive statements in painting, architecture, the textile and ceramic arts, as well as garden design. While that period preceded the arrival of prosperity, it clearly marked an extraordinary moment in Japanese cultural history, one frequently compared with the twelfth century of the Heian period.  [...] Rather than an emblem of immortality, as it is in Western lore, in Japan, the phoenix evolved out of its origins in Chinese mythology to become, by the sixteenth century, an auspicious symbol of political authority. Together with clusters of the distinctively shaped paulownia leaves, this long-tailed, mythical bird  [...] proclaiming an air of graceful command".  
  • 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."
  • Small iron tsuba for a dagger (tantō), of quatrefoil form (mokkō-gata), with raised rim (mimi), decorated with flat brass inlay (hira-zōgan) to form an abstract design alluding to the mushroom of immortality (reishi). Opening (hitsu-ana) to the left of nakaga-ana probably cut later and fitted with shakudo sekigane. Maker's signature on seppa-dai: Koike Naomasa (小池 直正).

    Momoyama period: End of the 16th - beginning of the 17th century. Dimensions: Height 53.7 mm; Width: 45.5 mm; Thickness at centre: 3.5 mm; at rim: 4.9 mm. Other examples of signed Koike Naomasa work in this collection: TSU-0346. Reference: The closest example in literature is in Compton Collection (II): №11 with the description: “A Koike School tsuba, Edo period (circa 1625), signed Koike Yoshiro. Sheet-brass flush inlay of cloud forms and wire inlay creating the same shape. Koike Yoshiro Naomasa worked from the Keicho to the Genna periods (1596-1623). He arrived in Kyoto from Kaga.” [Japanese Swords and Sword Fittings from the Collection of Dr. Walter Ames Compton (Part II) / Sebastian Izzard, Yoshinori Munemura. — Christie's, New York, October 22, 1992].

  • Iron tsuba of round form with three stylized folding fans motif  in openwork (sukashi). Kogai-hitsu-ana with shakudō sekigane. Iron bones (tekkotsu) on the rim. Momoyama period or earlier. Possibly, Ko-Shōami school.

    Size: 76.8 x 75.7 x 4.0 mm.

    [Seller alleged that the motif is "Buddhist wheel", which seems unlikely.
  • Circular tsuba (marugata ) with design of futatsu-domoe (twofold tomoe) in negative openwork (kage-sukashi), folded-over rim (uchikaeshi-mimi ). The ‘head’ of the left tomoe altered to form an opening for scabbard accessory (kata-hitsu-ana), adorned with gold ategane fitting with file marks (tate-yasurime). The hammer-blow finish of the surface (tsuchime-ji). Signed to the left of nakaga-ana: Yamakichibei (山吉兵). Attributed by Steve Waszak a the Second Generation (Nidai) master.

    Tomoe (Comma): The character (Chinese pronunciation bā). A pattern resembling the two-comma tomoe (futatsu-domoe) has been found in ancient cultures on all inhabited continents. ...aside from their military function, a ritual or fetish value, perhaps related to their testicular shape. It also has yin-yang connotation. The gold sekigane confirms the high value of the piece to the owner.
