Iron tsuba of round form decorated with dragonfly (tombo) and comma (comma-like swirl, tomoe) in openwork (sukashi) outlined with brass wire. The plate decorated with 5 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: Diameter: 89.5 mm, thickness: 3.1 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13].   Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."

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".  

Gomoku-zōgan tsuba. Iron, inlaid with brass scrap (gomoku-zōgan), and polished. Height: 75.3 mm; Width 74.9 mm; Thickness at seppa-dai: 3.6 mm. Weight 130.2 g. Edo, 18th century. Gary D. Murtha dedicates 10 pages to this type of tsuba: "...they were made by soldering brass overlay scraps to the iron plate". Actual gomoku-zōgan tsuba are seldom found in collections most likely because they have little if any artistic attributes. In addition, many have rough surfaces making them questionable for use on a sword. It is said that many of these were produced in Yokohama for export to the West during the late Edo period". G. D. Murtha then describes the technique of making gomoku-zōgan in every detail, and states that "The brass pieces are said to represent 'fallen pine needles', a description most likely created to add aesthetic value to help market the tsuba" [see:Gary D. Murtha. Japanese sword guards. Onin - Heianjo - Yoshiro. GDM Publications, 2016; pp. 160-161].

Oblong round shape (nagamaru-gata) tsuba with design of dragonfly (tombo or katsumushi) and wheel (kuruma) in negative openwork (kage-sukashi), round rim (maru-mimi ). Copper sekigane.

Okamoto Yasukazu's Owari to Mikawa no tankō, №181 characterizes the tsuba as follows: "Katsumushi, kuruma-sukashi no zu (dragonfly and wheel sukashi). Mei: Yamakichibei (Shodai). Such small tsuba are rare for the Shodai. The nakago-ana is also small so it was probably intended to be mounted on a tantō. Regardless of its size, the iron is outstanding and the workmanship shows the characteristic features of the Shodai (first generation). The kuruma-sukashi design is interpreted here in a half-moon shape and only on one side of the tsuba. Such a design is also seen on works of the Nidai (second generation)...". Signed to the left of nakaga-ana: Yamakichibei (山吉兵へ). Attributed to the First Generation (Shodai) master.

Iron tsuba of round form with a Marsilea (water clover, paddy plant, denjiso) in openwork (sukashi) and a cricket carved in low relief (katakiribori) with extremities and one antenna inlaid with brass; the other antenna is carved in kebori (which antenna is inlaid and which is carved alternates on the face and on the reverse). The plate decorated with vertical file stroke ornamentation (tate-yasurime). Raised dam-shaped rim (dote-mimi). Inscription from a previous collector in red oil paint: 22-71-1. Edo period, possibly 17th century. Katchushi school.

Size: 75.0 x 74.4 x 3.6 (center), 5.0 (rim) mm.

The plant Marsilea (paddy plant, denjiso), common names include water clover and four-leaf clover because the long-stalked leaves have four clover-like lobes and are either held above water or submerged. In The elements of Japanese design by John W. Dower, this motif is listed under the numbers 634-35 Paddy Plant (denjiso). Obviously, as a four-leaf clover it is an auspicious symbol. The four leaves radiate out as the shape of the kanji 田 (romaji 'ta'), which means 'rice paddy'. This symbol may be used as a family crest (mon), and this would be the most probable explanation of the sukashi on this tsuba.
