• Iron tsuba of round form represents an eight-spoke Wheel-of-the-Law and in the same time (because of the inner shape of cut-outs) - a sixteen-petal imperial chrysanthemum in openwork (sukashi). Decorated on both sides with vines, leaves, and tendrils in suemon-zōgan and sen-zōgan. Spokes and hitsu-ana decorated with rope-like linear brass inlay (nawame-zōgan). A somewhat look-a-like tsuba is referenced in Gary D. Murtha's Japanese Sword Guards. Onin-Heianjo-Yoshiro book on page 61. Mr. Murtha attributes his piece to Heianjo school of Azuchi-Momoyama or early Edo period. However, tsuba in this collection looks older and bolder than the one in his book. It is larger (84 mm vs. his 66 mm), the spokes are longer, the inlay is of better quality, it is relatively thin, with deep black patina, and with the traces of lacquer (urushi). This may indicate that this tsuba belongs to Ōnin school and dates at least to late Muromachi period, ca. 1550, if not 1450 AD. Mid to late Muromachi period (ca. 1450-1550). Dimensions: 84.3 x 83.2 x 3.2 mm "In Japan, the Wheel-of-the-Law is an attribute of such deities as  Senju Kannon, the Thousand-Armed Kannon, and Dainichi Nyorai, the principal deity of Shingon Buddhism [Merrily Baird]. May be used as a family crest (mon).

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.

Weight 82.7 g Inscription on the wooden box reads: "Muromachi period Mumei Zōgan Shingen Tsuba" Muromachi period, 16th century. Age attribution is based on the fact that the core is made of yamagane; later copies of Edo period are usually made of iron. This small and light tsuba was likely mounted on a combat sword, while larger and much heavier woven wire Shingen tsuba of Edo period were of purely decorative purpose. http://varshavskycollection.com/shingen-tsuba/

Size: 80.3 x 78.4 mm; thickness at seppa-dai: 3.4 mm; at the middle: 3.8 mm; before the rim: 2.4 mm, rim: 2.8 mm. Note on design: though this design resembles family crests with oak and mulberry leaves, I believe it's  a melon flower [see Jeanne Allen. Designer's guide to Samurai Patterns.

  • Small iron tsuba for a dagger (tantō), of quatrefoil form (mokkō-gata), with raised rim (mimi), decorated with flat brass inlay (hira-zōgan) to form an abstract design alluding to the mushroom of immortality (reishi).

  • Well-forged iron plate of round shape (maru-gata) is decorated with water weeds or arabesque (karakusa) in flat brass inlay (hira-zōgan) all over and eight family crests (mon) of round form in cast brass with delicate linear carving (kebori) and openwork (sukashi). Crests represent: [at 9 hours] three counter-clockwise commas or swirls (tomoe); [at 10:30] plum blossom (ume); [at 12:00, 1:130, and 7:30] - stylized flower made by cutting out five suhama symblos (flower-shaped suhama); [at 3:00] bellflower (kikyō); [at 4:30] seven-star crest (shichiyō-mon); [at 6:00] cherry blossom (sakura). Brass-trimmed ryo-hitsu. Copper sekigane. Yoshirō school. Momoyama or early Edo period, end of the 16th to first half of the 17th century (1574-1650). Inscription on seppa-dai: 八幡 - Hachiman. Size: height 89.6 mm, width 89.3 mm, thickness at seppa-dai 3,0 mm. Weight 129.7 g. NBTHK certificate № 4007685, June 27, 2015: HOZON (Worthy of Preservation). As for the inscription, Nihonto Message Board blog discussion provides the following explanation of the inscription: "An expression of conviction as to being the best under the sun". On the other hand, there may be more in this confluence of symbols: the tomoe crest at 9:00 is "the kamon of Hachiman, the war god" [Family Crests of Japan; Stone Bridge Press, Berkeley, CA, 2007, p. 108]. The character 八 in the inscription cut stronger than the other kanji, and may be by a different hand in different time. 八 (hachi, eight): "The numeral eight was appreciated because its shape broadens toward the bottom, symbolizing eternal expansion" [ibid, p. 119]. It may be said that this tsuba is dedicated to Hachiman. Other crests (suhama, bellflower, seven-stars, plum and cherry blossoms) collectively allude to "good old times" when Fijiwara and Taira clans were in full bloom. Markus Sesko believes that the inscriptions reads: Hachiman: "the inscription is/was HACHIMAN (八幡), the God of War and a relatively popular inscription for tsuba, swords and armor." Elliott Long and Robert Haynes provide the following explanation of the inscription: "...hachi is correct and represents the name of the HACHI SHRINE. The inscription reads 'YAWATA' which is the name of the mountain in Mino Province where the HACHI Shrine is located". Details on Hachiman Shrine in Yawata (八幡市) can be found elsewhere, including Historical and geographical dictionary of Japan by Edmond Papinot. Van Ham auction house provides the following description: MON-SUKASHI TSUBA. MARUGATA. Japan. Momoyama period. Yoshiro school. Iron with inlays of brass. In hira-zogan technique with kebori engraving eight different family emblems (mon). An old inscription is dedicated to the deity Hachiman. D.4.5mm, Ø 8.3cm. Condition A/B.
