Iron tsuba of round form with design of water plantain (omodaka) and wild goose in openwork (sukashi). Slightly rounded, square rim. Copper sekigane. Kyo school.

Provenance: Sasano Masayuki Collection, № 68: "The water plantain (omodaka) first appeared as a design for sword fittings in the Heian period. From such early beginnings, this decorative plant has shared a long history with the samurai. Also known as shogun's grass (shogununso), it was held in high esteem as a symbol of victory". The same tsuba was found at Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections. Sotheby's, London, Thursday 10 April 1997, page 22, item 60, saying that this is a "Kyo-sukashi tsuba, early to middle Edo period (late 17th/18th century) [Sotheby's attribution], and that it represents "a small bird among omodaka and aoi plants".  

Iron tsuba of slightly elongated round form with design of wild geese and drops on pampas grass (masashino) in openwork (sukashi). Rounded rim. Copper sekigane. Owari school. Early Edo period: early 17th century (Kan-ei era). Height: 78.8 mm. Width: 76.3 mm. Rim thickness: 6.1 mm. Center thickness: 6.4 mm. Provenance: Sasano Masayuki Collection, № 169. A description of musashino symbolism can be found at Symbols of Japan by Merrily Baird [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001]: Musashino - "the plain of Musashi - a large expanse in the Tokyo area, was celebrated in poetry for the grasses that grew there before the recent era of industrialization... The use of Musashino themes was particularly common in the Momoyama and Edo periods". Pampas grass with dew drops and wild geese in flight collectively provide strong autumnal connotation.  

Iron tsuba of oval form with design of iris and plank bridge (yatsubashi) in openwork (sukashi). Rounded cornered rim. Unsigned. Attributed to Jingo - 3rd generation Shimizu, 2nd generation Jingo (1691-1777) [M. Sesko, Genealogy..., p. 94]. Edo period: Late 18th century (Hohreki / Meiwa era). Height: 69.5 mm. Width: 65.2 mm. Rim thickness: 4.6 mm. Center thickness: 4.8 mm. Provenance: Sasano Masayuki Collection, № 251: "Shimizu. Third generation Jingo (died at 87 years of age in the sixth year of An-ei, 1777). The eight-section bridge with irises are arranged to create the design of 'yatsubashi'. The features are unique for the Shimizu school and show no influence of the Hirita, Nishigaki or Hayashi schools". The design visually resembles a butterfly. As described in Family Crests of Japan by Stone Bridge Press [Family Crests of Japan; Stone Bridge Press, Berkeley, CA, 2007], and also in Japanese Family  Crests by Yuzuru Okada [Yuzuru Okada. Japanese Family Crests // Series: Tourist Library: 37. Board of tourist industry; Japanese Government Railways, - 1941], there is a special technique used in construction of family crests, called 'reshaping' by the former and 'reconstruction' by the latter: "reconstruction is realized when a motive has its general shape composed of the detail of entirely different motive as, for instance, the crest of a butterfly formed of pine-needles. [...] The fanciful and ingenious forms evolved in this way may be represented by the kasiwa-giri or 'oak-leaf-paulownia', the ogi-bisi or 'fan-lozenge', the matuba-zuru or 'pine-needle-crane', the omodaka-kotyo or 'water-plantain-butterfly', etc." In our case we can call the motif yatsubashi-chocho or 'Iris-and-Bridge—Butterfly'.
