Edo period, 18th century. SOLD   Height: 98.0 mm, Width: 97.4 mm, Thickness at seppa-dai: 6.0 mm. Weight: 290 g. NBTHK certificate №436696: 'Hozon' attestation. Citing "JAPANESE SWORD-MOUNTS IN THE COLLECTIONS OF FIELD MUSEUM" by Helen C. Gunsaulus, Assistant Curator of Japanese Ethnology. 61 plates. Berthold Laufer, Curator of Anthropology. Field Museum of Natural History, Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p.45: "An unusual group of tsuba popular in the late sixteenth century and afterwards is made up of those guards known as Shingen tsuba, a name which was derived from a sixteenth-century warrior, Takeda Shingen (Takeda Harunobu, 1521-73), who is said to have preferred this style of guard, as it combined strength and lightness. Under the category of "Shingen", four different types abd generally listed, though a fifth appears in the drawings in the Boston Catalogue of Okabe Kakuya "Japanese Sword Guards" (p. 21). It is square, that form which is said to have been used in Ashikaga days for scaling walls, the sword having been set up as a step. [...] The following descriptions include, however, the Shingen tsuba usually met with.

1. So-called Mukade ("centipede") tsuba are made of iron in which a centepede is inlaid in brass or copper wire. Mukade tsuba of Myōchin and Umetada warkmanship have been found with the inscription, "Made to the taste of Takeda Shingen".
2. There are those of solid iron, with need centers of brass, to the edges of which is affixed a weaving of brass and copper wires which is bound to the foundation disk by a rim, usually decorated simply.
3. Another type is of solid iron, bored at intervals and laced with braided or twisted wires of copper and brass.
4. The fourth type is a chrysanthemoid form, chiselled in open work and laced or woven tightly with copper and brass wire."

I believe that my tsuba [№ TSU-0338] belongs to the fourth type. However, this particular specimen does not conform with the description of Shingen tsuba as combining strength and lightness. Its weight is 290 g, which tells us that most probably it had purely decorative function (as most tsuba in Edo period). A somewhat similar design can be found at wikimedia. A look-a-like tsuba is illustrated at Compton Collection, Part II, p.p. 26-27, №54. It is dated ca. 1700. It was in a box with Sato Kanzan inscription, and had NBTHK certificate attesttion of 'Tokubetsu Kicho'. Price realized: $5,280.

Iron tsuba of round form with circular iron wire fastened to the surface with iron and brass staples (mukade-zōgan); brass ring about 2.5 mm wide along the rim with chisel marks. Design repeats on the reverse. Copper sekigane. Early Edo, 17th century. Size: Height: 83.3 mm; width 83.9 mm; thickness at seppa-dai: 4.5 mm. Weight 173.6 g. Design is thought to resemble a centipede. "Centipede-like inlay (mukade zogan) of alternating iron and brass staples produce an appearance that was particularly favored by Takeda Shingen (1521-1573), one of the most powerful warlords of his time. The centipede is sacred to Bishamon (God of War) and especially propitious for a warrior. Shingen type, 16^th century.” [The Peabody Museum collection of Japanese sword guards with selected pieces of sword furniture, by John D. Hamilton. Photographs by Mark Sexton.

Shibuichi Kozuka carved in low relief (takabori, usuniku-bori) and inlaid in gold and silver with design of Shoko, reading by moonlight, thatch, pine rosettes, and fool moon. According to Henri L. Joly [LEGEND IN JAPANESE ART. London, 1908; LIB-1416 in this collection] Shoko was a Chinese student of Taoism who was so poor that he had no money to buy illuminating materials and read by moonlight. Shoko mentioned in the article about another Chinese character - Shaen, who was reading by the light emitted by glow-worms (see page 310). Signed on the back: Haruchika (春親) + kaō. Size: 97.3 mm (H) x 14.8 mm (W). Edo period, mid 19th century. NBTHK Certificate № 449542. Hamano Haruchika from Edo was a student of Haruyuki in 1848-54; Hamano School, Etchū Toyama Branch, according to M. Sesko's "Genealogy", page. 34. Most probably it is his work. Following the MFA data, it is also possible that "our" Haruchika is indeed Nara Haruchika or Tsuchiya Haruchika from Nara School; though I did not hind such artist in Markus Sesko books. However, in his "Toso-Kinko" on page 177 there is certain Shingorō who carried out his business under the name of Yanagawa Haruchika (1791-1857?)  

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 double crossbar and two family crests (hikiryo-ni-kamon) in openwork (sukashi). Squared rim. Copper sekigane. Owari school. Early Edo period: Late 17th century (Kanbun / Enppo era). Height: 80.9 mm. Width: 80.8 mm. Rim thickness: 5.0 mm. Center thickness: 4.6 mm. Provenance: Sasano Masayuki Collection, № 172: "A paulownia and a clover are diagonally opposite two crossbars. This expressive design suggests a Higo origin, but the iron and the finish are certainly of the Owari school. Work of this nature may have been influenced by Hayashi Matashichi (1613-1699)."

Iron tsuba of oval form with design of stylized paulownia (nage-giri) in openwork (sukashi). Leaf veins carved in kebori technique. Rounded rim. Copper sekigane. Unsigned. Attributed to Kanshirō, third generation Nishigaki (1680-1761). Edo period: Early 18th century (Kyoho / Genbun era). Size: Height: 77.8 mm. Width: 71.9 mm. Rim thickness: 5.9 mm. Center thickness: 5.0 mm. Provenance: Sasano Masayuki Collection, № 264: "Nishigaki. Third generation Kanshiro (died in in the eleventh year of Hohreki, 1761 at the age of eighty-two). This oblong shape appears a little amateurish at first, however, it was done intentionally to add flavor to to the design. The neat composition is a feature of the third Kanshiro."  

Copper tsuba of oval form carved in kebori and katakiribori with Tekkai Sennin sitting under bamboo on the face and with a pine tree on the back. Ishime-ji treated surface.

Signed on the reverse: Jōi (乗 意).

Edo period (First half of 18th century). Dimensions: 69.6 x 66.5 x 4.5 mm Sugiura Jōi (杉 浦 乗 意) was a master of Nara School in Edo; he was a student of Toshinaga [M. Sesko, 'Genealogies', p. 32]. "Sugiura Jōi (1701-1761) made many fuchigashira and kozuka, tsuba are rather rare." [M. Sesko, The Japanese toso-kinko Schools].
