    NBTHK Certificate № 463485. The certificate says it's a Higo School piece. The design was popular in both Akasaka and Higo schools. The Akasaka example: at Kodogu and tsuba.

  • Iron tsuba of round form with design of two paper lanterns in openwork (small cut-outs, ko-sukashi ) outlined with brass wire. The plate is decorated with four concentric rows of brass dot inlay (ten-zōgan), with a brass circular wire inside the innermost row of dots (missing on the back). Hitsu-ana of rectangular form is not outlined with brass wire, which let us suppose that it was cut out at a later date. Copper sekigane. Mid Muromachi period (1454-1513). Diameter: 74.0 mm, thickness: 2.6 mm. Tsuba is illustrated at: 新版 日本刀講座 小道具鑑定編 本間 薫山 佐藤 寒山 : Shinhan Nihonto Koza, Volume VI, Kodogu Part 1. Under supervision of Honma Kunzan and Sato Kanzan. 鍔 無名 応仁 鉄地) 丸形 小透 槌目 真鍮据文 点象嵌 丸耳 : Tsuba with no signature, Ōnin style. Base metal iron (jigane), round shape, small perforations (ko-sukashi), hammering finish (tsuchime). Pre-cast brass inlay (shinchu suemon-zōgan); dot inlay (ten-zōgan); round edge (maru-mimi). English translation of the book indicated above Nihon Tō Kōza, Volume VI, Part 1 by Harry Afu Watson, AFU Research Enterprises, Inc., 1993. Tsuba in question illustrated on page 14 and described as follows: " Tsuba mumei Ōnin. Tetsu ji maru gata ko-sukashi tsuchime shitate shinchū suemon ten zogan maru mimi. Brass suemon". My question remains: why such a text is called 'translation' while it looks more like transliteration of romanization?
  • Iron tsuba of square with cut-off edges form (sumi-iri-kakugata) with lattice design in openwork (sukashi) and pierced center.

    Unsigned. Late Muromachi period, ca. 16th century.

  • Iron tsuba of round form (maru-gata) with 8 openwork petals outlined with brass wire (sen-zōgan) and decorated with brass dots (ten-zōgan), on both sides.

  • Iron tsuba of round form with design of two parallel crossbars and two rings in openwork (sukashi). Rounded square rim. Moderate iron bones (tekkotsu) allover. Copper sekigane. Kanayama school. Momoyama period (or late Muromachi). Size: 74.5 x 74.0 x 5.5 mm. The rings possibly represent the sun and the moon, or the stars. The parallel crossbars may represent the "two stripes" (futatsu biki) family crest (incl. Ashikaga family).
  • Iron tsuba of mokkō form decorated with inome (wild boar's eye) in openwork (sukashi) outlined with brass wire. The plate decorated with 3 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Some dots and the outline of inome on the face are missing.

    Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: 72.1 x 71.3 x 2.3 mm.
  • Kyo school iron tsuba of round form decorated with an eight-plank bridge (yatsuhashi) and irises (kakitsubata) in openwork (sukashi).

    Late Muromachi period, Tenbun era (early 16th centiry).

    Dimensions: 80.0 x 77.2 x 4.1 mm.

    The design alludes to the scene in 'Ise Monogatari', where Ariwara no Narihira being exiled from Kyoto to the Kanto region crossed the eight-plank bridge at Mikawa looking at the irises in bloom and composed a poem expressing his desire to return to Kyoto. A lot of tsuba have been produced with the similar design.

  • Iron tsuba of a spindle shape (tate-itomaki-gata) pierced and inlaid in brass suemon-zōgan with bellflowers, vines and foliage, and a dragonfly in the upper right corner, on both sides. One of the hitsu-ana plugged with grey metal (led or pewter), nakaga-ana fitted with copper sekigane. The shape of the tsuba may be interpreted as  four saddles connected to each other by horse bits. Such a design of sukashi and zōgan is usually attributed to Kaga Yoshirō branch of Heianjo school, active in the second half of the 17th century (c. 1650-1700). Size: 95.9 mm diagonal; 4.1 mm thickness. Tokubetsu Kicho certificate № 332 issued by NBTHK on October 12, 1965.  
  • Iron tsuba of octafoil form with design of rudder (kaji) and lake in openwork (sukashi) outlined with brass wire. Thin plate also decorated with three concentric circular rows of brass dots (nail heads) in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire. Cut-outs for kozuka and kogai probably added later.  Slightly raised rim between the indentations (suki-nokoshi-mimi). The inlaid metal of red-ish hue, so it may be copper, not brass. Sekigane, visible on the NBTHK paper photo, are missing, possibly removed by a previous owner. Muromachi period. Ōnin school. Unsigned. Dimensions: 81.2 mm x 81.8 mm x 2.7 mm. Weight: 79.0 g. Large nakago-ana: 34 mm high and 10 mm wide. NBTHK certificate №455786: Hozon. Note regarding design: it was quite hard to interpret the big oval opening. The first suggestion was 'sea cucubmer', and it was based on a design published by Kazutaro Torigoye [Kodogu and tsuba. International collections not published in my books (Toso Soran), 1978] on page 202: Katchūshi tsuba: Sea cucumber and butterfly. Look and judge yourself:

    Torigoye: sea cucumber and butterfly.

    The second suggestion - 'lake' - came from [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014], page 14 №5:

    Ko-Katchūshi tsuba: Lake and pine.

    Opening on my tsuba looks more like the 'lake'. Also, rudder and lake make more sense than rudder and sea cucumber. At least to me...    
  • Iron tsuba of round form with design of military commander's fan (gunbai) in openwork (sukashi). Square rim. Hitsu-ana plugged with lead or tin. Ko-tosho school. Mid-Muromachi period (1454-1513), Entoku era (1489-92) / Meio era (1489-1501). Height: 80.3 mm, Width: 81.5 mm, Rim thickness: 3.0 mm. Centre thickness: 3.5 mm. Provenance: Sasano Masayuki Collection,  №23 in Japanese Sword Guard Masterpieces from the Sasano Collection, 1994: Ko-tosho. Sukashi design: Military commander's fan (gunbai). Mid Muromachi period. Late 15th century (Entoku / Meio era). The military commander's fan (gunbai) was cherished by samurai warriors. This tsuba is relatively thick, with the large fan nicely positioned on the plate.
  • Iron tsuba of round form with brown patina decorated with the design of a Buddhist temple bell (tsurigane) in openwork (sukashi), with details outlined in brass wire (sen-zōgan), the outer ring  decorated with two rows of brass dots (ten-zōgan), and the bell details carved in sukidashi-bori as on kamakura-bori pieces.

    Ōnin school. Unsigned. Late Muromachi period, 16th century. Dimensions: 88.8 x 88.3 x 3.0 mm. As per Merrily Baird, two legends are usually associated with the image of tsurigane, a large, suspended Buddhist bell: one is that of Dojo Temple (Dojo-ji), and the other is of Benkei stealing the tsurigane of Miidera Temple. Interestingly, this type of bell (tsurigane) is not described as a family crest (mon), while suzu and hansho bells are.
