    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 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 represents an eight-spoke Wheel-of-the-Law and in the same time (because of the inner shape of cut-outs) - a sixteen-petal imperial chrysanthemum in openwork (sukashi). Decorated on both sides with vines, leaves, and tendrils in suemon-zōgan and sen-zōgan. Spokes and hitsu-ana decorated with rope-like linear brass inlay (nawame-zōgan). A somewhat look-a-like tsuba is referenced in Gary D. Murtha's Japanese Sword Guards. Onin-Heianjo-Yoshiro book on page 61. Mr. Murtha attributes his piece to Heianjo school of Azuchi-Momoyama or early Edo period. However, tsuba in this collection looks older and bolder than the one in his book. It is larger (84 mm vs. his 66 mm), the spokes are longer, the inlay is of better quality, it is relatively thin, with deep black patina, and with the traces of lacquer (urushi). This may indicate that this tsuba belongs to Ōnin school and dates at least to late Muromachi period, ca. 1550, if not 1450 AD. Mid to late Muromachi period (ca. 1450-1550). Dimensions: 84.3 x 83.2 x 3.2 mm "In Japan, the Wheel-of-the-Law is an attribute of such deities as  Senju Kannon, the Thousand-Armed Kannon, and Dainichi Nyorai, the principal deity of Shingon Buddhism [Merrily Baird]. May be used as a family crest (mon).

  • 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.

  • 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 could have been trimmed with brass now lacking. Nakago-ana of triangular form, possibly enlarged, with copper sekigane. 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 round form profusely decorated with brass inlay of plants, birds, well, and family crests (mon) in suemon-zōgan technique and occasional brass dots (nail-heads) or ten-zōgan. Seppa-dai and kozuka-hitsu-ana outlined with brass inaly, possibly repaired: rope-shaped wire here and there replaced with flat wire. The plate is very thin, with remnants of lacquer. Ōnin school. Size: 75.8 x 75.2 x 2.3 mm. Weight: 77.5 g. On the front side (omote) motif includes the following elements (from 12 o'clock, clockwise):
    1. Water plantain (a.k.a. arrowhead, or omodaka): "a perpetual plant of the water plantain family, was also called shōgunsō (victorious army grass). Because of this martial connotation, it was a design favored for the crests of samurai families" [see: Family Crests of Japan. // Stone Bridge Press, Berkeley, CA, 2007; p. 63].
    2. Heron (sagi): "...considered an emblem of longevity, and from China comes the practice of regarding the bird as a mount of the gods and the Taoist sennin. [...] heron also reflects an inauspicious connotation, for the word sagi is homophone for 'fraud' and 'false pretenses'." [see: Merrily Baird. Symbols of Japan. Thematic motifs in art and design. // Rizzoli international publications, Inc., 2001; p. 112]. Some may say, that this is not a heron but a crane (tsuru). It's very possible, and in this case the negative connotation is lost, but the reference to longevity and allusion to sennin remain.
    3. Pampas grass (susuki, or obana): as per Merrily Baird, p. 95 and John W. Dower, p. 66, pampas grass is one of the Seven Grasses of Autumn. When combined with flying wild gees, conveys strong autumnal mood.
    4. Plum blossom (ume): according to Merrily Baird, the flower has a vast variety of symbolic meanings, including longevity, and a reference to the Chinese Taoists. It is used in 80 family crests [see: Japanese Design Motifs: 4,260 Illustrations of Japanese Crests; Compiled by the Matsuya Piece-Goods Store; Translated by Fumie Adachi. // Dover Publications, Inc., 1972.] Plum is "celebrated for its sweet perfume, delicate blossoms, and habit of blooming at the end of winter".
    5. Tree flying wild geese (kari): "Wild geese arrive in large flocks in southern regions during the autumn months, and following their migratory instincts, head back north in spring" [Family Crests of Japan, pp. 85-86]. "The importance of geese in Japanese art was further secured by stories of several military heroes who had achieved victory in battle when a sudden breaking of ranks by flying geese signaled an ambush. The protective role of the birds led to their frequent use in decorating sword furnishings and possibly also their adoption as a family crest motif.Finally, the goose in Asia plays a role in religious traditions" [Merrily Baird, pp.111-112].
    6. Hikiryō (line, or bar, or stripe) - a symbol which consists of one, two, or three horizontal or vertical stripes in a circle. "In wartime, Japanese generals [...] surrounded their encampments with huge cloth curtains. Usually these were made of cloth sewn together horizontally and varying in color [...] to distinguish the individual general and his followers. The stripe thus assumed strong martial connotations, and became a mark of identification on personal military gear as well. In the early fourteenth century  the heads of the Ashikaga and Nitta, then the two most powerful clans in Japan, both adopted stripe patterns as a family crest". [See: Family Crests of Japan, p. 111 and John W. Dower. The elements of Japanese design - A handbook of family crests, heraldry & symbolism. // Weatherhill, New York, Tokyo, 1985, p. 144].
    On the reverse (ura) motif includes the following elements (from 12 o'clock, clockwise):
    1. Hikiryō, see above.
    2. Pampas grass (susuki, or obana), see above.
    3. Bellflower (kikyo): One of the Seven Grasses of Autumn. "As a crest, it have been adopted among the warriors around the thirteenth century, primarily because of it's beauty" [John W. Dower, p. 48].
    4. Four flying wild geese (kari), see above.
    5. Weeping willow (yanagi): "It is commonly represented with water, snow, swallows, or herons.  A branch of willow (yoshi) is one of the attributes of the Buddhist deity Senju Kannon (Thousand-Armed Kannon), who is said to use the branch to sprinkle the nectar of life contained in a vase. [Merrily Baird, pp. 66-67].
    6. Lone plum blossom in a well frame/crib (igeta, izitsu): "Well crib was one of the most popular motifs in Japanese heraldry".  As a crest it may stay simply for the first character (i) of the family name, however, with a flower inside the well frame, and together with the other symbols present, it may aggravate the sense of autumn-ness. The ten-zōgan dots in this particular case may represent the snowflakes or autumn stars.
    The beholder may imagine a high-ranking samurai resting near a river or lake after the battle. Surrounded by clusters of pampas grass, he's watching a flock of geese flying in the skies; it is late in the autumn, and the occasional snowflakes hover around; heron is walking amidst the arrowheads, hunting for food. The last lonely plum blossom floating in a well... According to Gary D. Murtha, this type of tsuba "could be considered as Onin or as early Heianjo work. The brass trim around kozuka hitsu-ana and the seppa-dai are characteristics of Onin work [see: Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27].

  • Iron tsuba of mokko form (quatrefoil) decorated with a pair of cherry blossoms (sakura) in small openwork (ko-sukashi) and inlaid in brass (suemon-zōgan) with designs of waves, distant pines, chrysanthemum flowers in halves, tendrils and leaves, lightning or thunder symbol (inazuma), flying geese and family chrests (mon): two interlocked rings (wachigai) on the face, and three encircled stripes (maru-no-uchi-ni-mitsuhikiryo) - kamon of the Kikkawa clan  - on the reverse. Hitsu-ana outlined with inlay of brass wire. Surface treated with lacquer. Copper sekigane. Though some consider this type of tsuba to resemble Heianjo school, “...the brass trim around the hitsu-ana is a characteristics of Ōnin work” [Japanese sword guards. Onin – Heianjo – Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]. The Ōnin origin is reinforced by scattered ten-zōgan elements here and there through the plate. It is possible that the tsuba was initially of round form and later trimmed to mokko shape. Mid Muromachi period; 15th century. Dimensions: Height: 87.2 mm; Width: 87.9 mm; Thickness at seppa-dai: 3.6 mm.
  • 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 round form inlaid with brass, copper, and shakudō wire fastened to the surface with metal staples (mukade-zōgan); Scalloped brass inlay around the rim. Early Edo, 17th century. Height: 84.8 mm; Width 84.8 mm; Thickness at seppa-dai: 3.7 mm. Weight 161.6 g. Design is thought to resemble a centipede. "Centipede-like inlay (mukade zogan) of alternating iron and brass staples produce an appearance that was particularly favored by Takeda Shingen (1521-1573), one of the most powerful warlords of his time. The centipede is sacred to Bishamon (God of War) and especially propitious for a warrior.
