International collections not published in my books. (Toso Soran). Ph. D. Kazutaro Torigoye, 1978, p. 246: "Late Edo. Jiyūgata. Sined: Akasaka Tadanori saku."   The Higo example can be found at Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 69, №56: Sugomori-tsuru sukashi-tsuba (Nesting Carne). Mumei: Matashichi (1st generation), early 17th century.

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'.  

Iron tsuba of quatrefoil form with design of bamboo stems and leaves, and a plank bridge in openwork (sukashi). Hitsu-ana of irregular form. Iron with smooth chocolate patina. Copper and shakudō sekigane. This piece is illustrated in Sasano: Japanese Sword Guard Masterpieces from the Sasano Collection, 1994 on page 295 under № 254 with the following description:

Nishigaki. First generation Kanshiro (died in the sixth year of Genroku, 1693, at the age of 81). Sukashi design: Bamboo (take). Early Edo period, late 17th century (Kanbun / Enppo era). Height: 72.6 mm; Width: 71.5 mm; Rim thickness: .6 mm; Centre thickness: 5.1 mm. Rounded rim. The shape of this sword guard is a quatrefoil and the design is arranged in the form of a saddle flap. Two bamboo trunks with leaves comprise the design. Calm, soothing and sophisticated are the features of this artist in his later years. Such characteristics may remind one of the work of the first Hikozo.

Provenance: Sasano Masayuki collection, № 254. What is interesting, and what had been found by Bruce Kirkpatrick, is that in the earlier photograph of the same piece ['Sukashi tsuba - bushido no bi' by Sasano Masayuki, photography by Fujimoto Shihara, 1972 (in Japanese), page 245, №201] we clearly see kebori - linear carving that decorates the bamboo leaves and the planks of the bridge. The said kebori have totally disappeared between 1972 and 1994. The tsuba became absolutely flat! Now we can only speculate about the reasons for such cruel treatment of the artistically and historically important item.
