• 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'.

  • Ko-kinko ymagane cast tsuba of mokko form (kirikomi-mokkō-gata) with chiseled diaper pattern of double head waves on both sides and a rabbit cast and carved with its eye inlaid in yellow metal (gold or brass) on the face. Fukurin which holds together the sandwiched layers of metal (sanmai) is about 2.4 mm wide. A look-a-like tsub of oval form instead of mokko-gata  is illustrated at Robert E. Haynes's Catalog #3,1982 on page 11, lot 15: "Rare design in style of Sanmai (three layers) / Wasei work. With yamagane core and heavy rim cover. The web plates are carved with double head Goto style waves and the face has a fox. The web plates were riveted at the seppadai.  See Lot 4, page 8. Ca. 1350. Ht. 6.6 cm, th. 3 mm" [underscore mine]. Quality of photo is so poor that I decided not to provide it here. Muromachi (if we follow Robert) or Momoyama period. The Momoyama attribution is mostly based on a fact that "waves and rabbit" motif became most popular in Momoyama times. Size: 68.5 x 59.8 x 4.0 mm. NBTHK Certificate № 423120. This tsuba is listed at Yakiba website with the following passage: "Attributions as well as dating of this type of tsuba has been the subject debate over the years. There are those who believe these type of tsuba to be ko-Mino (early Mino School) tsuba, others believe them to be tachi-kanaguchi tsuba. Still others insist they are simply ko-kinko (early soft metal) tsuba. This tsuba was authenticated and determined to be "Ko-Kinko" by the NBTHK". Oval form tsuba with the same design can be found in this collection - TSU-0323.
