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 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 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].

Large iron tsuba with hammer marks on the surface, small oval opening to the right of nakaga-ana; yamagane fukurin chiselled with tortois shell diaper pattern.

Early Muromachi period (1393-1453). Size: 101.2 x 101.9 x 2.4 (center), 5.2 (rim) mm; weight: 148.4 g.  

The thin, four-lobed iron plate of brownish color is carved on each side with two concentric grooves in the middle of the web, and with four thin scroll lines (handles, kan) that follow the shape of the rim. The hitsu-ana were added at a later date.  Copper sekigane. Kamakura-bori school. Muromachi period, circa 1400-1550. Size: Height 80.4 mm, width 79.0 mm, thickness 3.2 mm at seppa-dai and 2.7 mm at the rim. Weight: 97.7 g. NBTHK Certificate №4004241: 'Hozon' attestation. As for the motif: the concentric circles is a widespread and generic design. It is described by John W. Dower [The Elements of Japanese Design, 1985, p. 132, #2201-30] as follows: Circle: Enclosure (wa). As a crest by itself, the cirlce carries obvious connotations of perfection, harmony, completeness, integrity, even peace. [...] Ordinary circles are labeled according to their thickness, with terminology ranging from hairline to "snake's eye". The motif that is described by both Compton Collection and R.E. Haynes as "scrolls", presented by John W. Dower as "Handle (kan): Although probably a purely ornamental and nonrepresentational design in origin, over the centuries this motif acquired the label kan, denoting its resemblance to the metal handles traditionally used on chests of drawers. [...] Very possibly the "handle" motif represents an early abstract version of the popular mokko, or melon pattern." Early Chinese Taoists claimed that special melon was associated with the Eastern Paradise of Mount Horai just as life-giving peaches were associated with the Western Paradise of the Kunlun Mountains. [...] A design motif called mokko (also translated as "melon" in accordance with the two ideographs with which it is written) may have nothing to do with the fruit. Mokko designs... are widely used as crests of both private families and Shinto shrines and are repeated as background designs that evoke a sense of classicism" [Symbols of Japan. Merrily Baird, 2001]. There is a look alike tsuba at Dr. Walter A. Compton Collection, 1992, Christie’s auction, Part II, pp. 14-15, №16: The description goes: “A kamakurabori type tsuba, Muromachi period, circa 1400. The thin, six-lobed iron plate is carved on each side with a wide groove that follows the shape of the rim, and with six scroll lines and a single thin circular groove. […] The hitsu-ana was added at a later date, circa 1500-1550.  Height 8.3 cm, width 8.6 cm, thickness 2.5 mm.
