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 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 round form with design of water plantain (omodaka) and wild goose in openwork (sukashi). Slightly rounded, square rim. Copper sekigane. Kyo school. Late Muromachi period: Early 16th century (Tenbun era) [Sasano's attribution]. Height: 76.2 mm. Width: 75.8 mm. Rim thickness: 5.3 mm. Center thickness: 4.5 mm. 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".

"What Sōminis in the East (Edo), Nagatsune is in the West (Kyōto)." “Since Nara period, Japanese fishermen in small boats have used cormorants (u) to catch river fish at night, binding the necks of the birds so that the fish are not swallowed. […] The bird and the work it performs are symbols of selfless devotion to one’s master and keen eyesight.” – from Merrily Baird 'Symbols of Japan.

Diameter: 82.0 mm; Thickness: 2.8 mm Cited from Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 72: "In Japanese art, the appearance of bamboo shoots is often without symbolic meaning. In other cases, however, the shoots are emblematic of Moso (Chinese: Meng Tsung/Meng Zong), a paragon of filial piety who dug through snow to find shoots for his mother. ... especially in miniature art forms, let bamboo shoots alone speak for the full story." The full story is this (See THE TWENTY-FOUR PARAGONS OF FILIAL PIETY [ERSHISI XIAO]):

Tears That Brought Bamboo-shoots From the Frozen Earth: Meng Zong Meng Zong lived during the Three Kingdoms Period of China's past. His father died when he was young, and he and his mother struggled to survive. One winter his mother was stricken with a serious illness, and craved some bamboo-shoot broth as medicine. But in the depths of winter, with snow and ice blanketing the ground, where was anyone to find fresh bamboo shoots, shoots that emerge only in the warm months? Nonetheless, Meng Zong, to avoid disappointing his mother, bravely fetched his shovel and went out into the white landscape in search of bamboo shoots. In the thicket he found only frosted leaves and green stalks coated with snowflakes and ice. Look as he might, there were simply no fresh shoots growing in the winter. The thought of his poor mother lying sick on her bed, waiting for bamboo-broth medicine, made his heartache. Uncontrollably, tears began to fall in rivers to the ground beneath the tall, emerald canes. Even now, as his tears flowed down, he kept a light of faith in his heart. If he was truly sincere in his search, perhaps.... Just then Meng Zong nearly tripped and fell over a sharply protruding lump of earth. He quickly knelt down and knocked aside the dirt with his trembling fingers. How uncanny! Underneath his frozen hands he discovered a bed of fresh, tender bamboo shoots! Overjoyed, he gathered up a coatful and carried them back home. The broth that he quickly set stewing in the pot soon cured his mother's illness. The neighbors, hearing the story, exclaimed that it was the strength of his sincere, unselfish, filial resolve that inspired heaven and earth to respond, and to bring up, out of season, the fresh shoots that cured his mother's disease. Before Meng Zong's prayers generated this miracle, it was normally considered impossible for bamboo shoots to grow in the winter. After the nmiracle took place, however, people were able to gather and to eat bamboo shoots all year round. The winter variety that existed hereafter became known as "winter shoots." The villagers were deeply influenced by Meng Zong's courage and devotion. They renamed the spot where the event took place, "Meng Zong's Bamboo Grove". We can now enjoy bamboo sprouts during the winter as well, and as we do so, it is fitting to recollect Meng Zong's outstanding example of filial respect, and reflect on our conduct as sons and daughter of our parents. A verse in his honor says, His teardrops transformed winter at the roots; Up from the ice crept tender bamboo shoots. Instantly, the winter-sprouts matured; Heaven's will: a happy, peaceful world.
