  • Iron tsuba of round form with design of hatchet executed in openwork (sukashi) and three fan panels motif on both sides carved in low relief (sukidashi-bori). Designs on the fan panels - face: bellflower, plum blossom in mist, grass leaves; - back: clouds, grass, and half plum blossom in mist. Copper sekigane. Koga-hitsu-ana probably cut out on a later date. Kamakura or kamakura-bori school. Edo period. Height: 83.8 mm, Width: 82.2 mm, Thickness at seppa-dai: 3.2 mm. NBTHK certificate № 4005500: Hozon (worthy of preservation).
  • The thin, four-lobed iron plate of brownish color is carved on each side with two concentric grooves in the middle of the web, and with four thin scroll lines (handles, kan) that follow the shape of the rim. The hitsu-ana were added at a later date.  Copper sekigane. Kamakura-bori school. Muromachi period, circa 1400-1550. Size: Height 80.4 mm, width 79.0 mm, thickness 3.2 mm at seppa-dai and 2.7 mm at the rim. Weight: 97.7 g. NBTHK Certificate №4004241: 'Hozon' attestation. As for the motif: the concentric circles is a widespread and generic design. It is described by John W. Dower [The Elements of Japanese Design, 1985, p. 132, #2201-30] as follows: Circle: Enclosure (wa). As a crest by itself, the cirlce carries obvious connotations of perfection, harmony, completeness, integrity, even peace. [...] Ordinary circles are labeled according to their thickness, with terminology ranging from hairline to "snake's eye". The motif that is described by both Compton Collection and R.E. Haynes as "scrolls", presented by John W. Dower as "Handle (kan): Although probably a purely ornamental and nonrepresentational design in origin, over the centuries this motif acquired the label kan, denoting its resemblance to the metal handles traditionally used on chests of drawers. [...] Very possibly the "handle" motif represents an early abstract version of the popular mokko, or melon pattern." Early Chinese Taoists claimed that special melon was associated with the Eastern Paradise of Mount Horai just as life-giving peaches were associated with the Western Paradise of the Kunlun Mountains. [...] A design motif called mokko (also translated as "melon" in accordance with the two ideographs with which it is written) may have nothing to do with the fruit. Mokko designs... are widely used as crests of both private families and Shinto shrines and are repeated as background designs that evoke a sense of classicism" [Symbols of Japan. Merrily Baird, 2001]. There is a look alike tsuba at Dr. Walter A. Compton Collection, 1992, Christie’s auction, Part II, pp. 14-15, №16: The description goes: “A kamakurabori type tsubaMuromachi period, circa 1400. The thin, six-lobed iron plate is carved on each side with a wide groove that follows the shape of the rim, and with six scroll lines and a single thin circular groove. […] The hitsu-ana was added at a later date, circa 1500-1550.  Height 8.3 cm, width 8.6 cm, thickness 2.5 mm. The tsuba was initially intended  to be mounted on a tachi of the battle type in use from Nambokucho to early Muromachi period (1333-1400)”. Sold at $935. And another one in Robert E. Haynes Catalog #9 on page 24-25 under №23: R.E. Haynes description: “Typical later Kamakura-bori style work.

  • Iron tsuba of six-lobed (mutsu-mokkō-gata) form, with six wild boar's eye shape (inome) openings (sukashi). Hitsu-ana and the entire perimeter of tsuba have typical for this school raised rim. Lobes are decorated with landscape motifs in low relief carving (sukidashi-bori). On the obverse: A hut under a full moon, Shinto shrine gates (torii) with pines and a full moon, rocks, a large pine tree, and a temple (pagoda) surrounded by rocks and waves. On the reverse: waves, fishing boat, wild gees in flight under full moon, maple, hexagon (tortoiseshell, kikko) with a dot inside and a dot outside (inclusion/exclusion symbol), and chrysanthemum (the last two may be family crests, mon).

    Compton Collection, part II, pp. 14-15, №17: Kamakura-bori tsuba, ca. 1450.

    NBTHK paper says that the motif is Hakkei (八景), i.e. "Eight Views," so several interpretations are possible (the original Chinese ones, Omi Hakkei, etc.).  However, most likely it is the 'Eight views of Omi' (近江八景  - 'Omi Hakkei'). Why the artist selected a 6-lobed form for depicting 8 views remains unclear, and thus we are in our right to raise the question whether the motif is indeed Hakkei. The term Omi hakkei (eight views of Omi) refers to painting or print sets which illustrate life on the shores of Lake Biwa in Omi (now Shiga Prefecture). The model for such paintings came from China, where, from the eleventh century onward, painters had produced eight views of the Hsiao and Hsiang lake areas of Hunan Province. The themes, which follow the original Chinese models, are: geese descending to land, returning fishing boats, clearing rain, a snow-covered evening landscape, the autumn moon, night rain, a temple bell at evening, and the glow of sunset. Japanese artists have also used the eight-theme approach for other parts of country - including cities - and applied it to subject matter other than landscapes. [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, page 308-9]. Japan Encyclopedia by Louis Frédéric also mentions Omi Hakkei as "Eight landscapes of Omi", and states that this theme was often cited in poetry after 1500. It is likely that the tsuba in focus is designed under the influence of the theme popularity in the 16th century. The theme was effectively exploited by prominent ukiyo-e artists Suzuki Harunobu and Utagawa Hiroshige in the 18th and 19th century, respectively. These are the eight scenes of the theme (see Wikipedia):
    • Returning sails at Yabase (矢橋の帰帆) - Yabase. Yabase is an old harbour on the east side of the lake. Near the Tokaido, it was used for a shortcut to Otsu by boat.
    • Evening glow at Seta (勢多(瀬田)の夕照) - The Chinese Bridge at Seta. The long bridge across the Seta was used by the Tokaido. In the background the "Fuji of Omi", the Mikamiyama. It is just above 400 m, but indeed well visible.
    • Autumn moon at Ishiyama (石山の秋月) - Ishiyama Temple. The Ishiyamadera was located on a hillside next to the Seta River. It got his name form the strange rocks on which it is built, partly on supporting beams. A hut at the upper end of the site allows a view of the lake, and the moon.
    • Clear breeze at Awazu (粟津の晴嵐) - Awazuhara. Awazu is well known for its pine wood, Awazu-ga-hara.
    • Evening bell at Miidera (三井晩鐘) - Mii-dera. Miidera temple was built in the 8th century. Its famous bell is one of the "Three bells of Japan", the other two being those at Byoodo-in, Uji and at Jingoji, Kyoto.
    • Evening rain at Karasaki (唐崎の夜雨) - Karasaki Shrine. Karasaki is a small cape with a single large pine tree, a hitsu-matsu.
    • Wild geese returning home at Katata (堅田の落雁) - Ukimido. Alighting geese cannot be seen always, however the little temple near Katata in the square hōkyō-style, detached from the lakeside, connected by a bridge. The first part of the name uki is the same as in Ukiyo-e, meaning floating. Midō means temple.
    • Evening snow at Hira (比良の暮雪) - Hira Mountains. The Hira mountains on the west side of the lake experience the hard winter, when the winter monsoon brings much snow from the continent.
    In any case, as a conservative, I say that it is a landscape motif and a late Muromachi period work, rather than Omi hakkei motif and a mid-Muromachi work.
  • Iron tsuba of round form pierced with design of paulownia (kiri) in a circle in positive silhouette (ji-sukashi), details carved in low relief (sukidashi-bori). Hitsu-ana were cut later and then both plugged with lead or pewter. Brown patina. The most unusual characteristic of this tsuba is its 'positiveness': the absolute majority of Kamakura-bori tsuba are of ko-sukashi type, i.e. with small openings, presenting the motif in negative silhouette. Kamakura-bori school. Muromachi period (ca. 1450). Size: Height: 85.1 mm, width: 84.8 mm, thickness at seppa-dai: 3.2 mm, at rim: 2.8 mm. Weight: 79.1 g. A similar tsuba is presented at Japanese Swords and Sword Fittings from the Collection of Dr. Walter Ames Compton. Part I. Christie's, New York, March 31, 1992, page 11, №3: "A Kamakura-bori tsuba. Muromachi period, ca. 1450. The round iron plate is pierced with an openwork design of a paulownia crest (kiri-mon), the surface details of which are carved in low relief.

  • Round iron plate of grey colour decorated in low relief (sukidashi-bori) on the face with sea waves (both layered waves, seigaiha, and rough waves, araumi), sago palm (cycas revoluta, sotetsu), presumably orchid leaves (ran) - five of them - hanging from the above, and  reeds (ashi), and on the back with waves (seigaiha only), rocks, chrysanthemums (kiku), clove (chori), reed, and presumably orchid leaves - three of them - hanging from the above. The kozuka-hitsu-ana was probably cut later. The plate is lacking the raised rim, typical for the kamakura-bori school. Muromachi period Dimensions: Height: 76.8 mm, width: 76.1 mm, Thickness at seppa-dai: 3.3 mm, at rim 2.0 mm. Height of nakago-ana: 29 mm. Weight: 82.4 g.

IMPORTANT JAPANESE SWORDS, SWORD FITTINGS AND ARMOR. Auction Monday, November 19th, 1979. Sale # 3063 under lot № 66. It describes the piece as following: “Kamakura bori work of the Muromachi period. Round thin plate with some small iron bones in the edge. Carved with design of plants (sego palm) rocks, and waves on the face. The back has half of two chrysanthemums, waves, clove, and sego palm leaves. The kozuka-hitsu has been added and later enlarged. A good typical example without the rim most have.

  • Mokkō-form (kirikomi-mokkō-gata) iron plate of grey colour decorated on both sides with waves, reeds, cloud, pagoda, and thatched hut in low relief (sukidashi-bori). The kozuka-hitsu-ana is original, the kogai-hitsu-ana probably cut later (lacks raised rim, fuchidoru). Wide (5.7 mm) raised rim of rounded square dote-mimi type, decorated with fine cross-hatching. Momoyama period, 16th century. Dimensions: Height: 75.9 mm, width: 76.4 mm, Thickness at seppa-dai: 2.3 mm, at rim 4.4 mm. Kamakura-bori tsuba of such a form is unusual. The rim is also unusual; it is possible that cross-hatching was done as a preparatory step for damascening, or the the damascening (gold or silver) disappeared with passage of time.
  • Thin iron plate of round form and black color carved in sukidashi-bori with design of rocks, waves, clouds, temple gates (torii), mountain pavilion and 5-storey pagoda on both sides, alluding to Todai-ji temple in Nara. Hitsu-ana pierced later. Very narrow very slightly raised rim. Copper sekigane.

  • Iron tsuba of six-lobed (mutsu-mokkō-gata) form, with six wild boar's eye shape (inome) openings (sukashi). Ryo-Hitsu and the entire perimeter of tsuba have typical for this school raised rim; raised seppa dai. Lobes are decorated in low relief carving (sukidashi-bori). On the obverse: chrysanthemum, Genji mon, waves and rocks, grasses and star, bellflower, star and flower in tortoiseshell (kikko).

    This tsuba, TSU-0401.2019, is the biggest of all three (another mine and the one from Campton Collection). The presence of a flower in a tortoiseshell symbol (crest or mon) on this tsuba alludes to Izumo Shrine. The overall piece, with symbols of grasses, waves, flowers, incense, stars, and flying geese, is full of autumnal connotations.  
  • Iron tsuba of round form, on both sides decorated in low relief (kebori) with a dragon, eyes inlaid in brass. NBTHK: Hozon, № 4011013. Kamakura-bori type of tsuba. Med-Muromachi period, c. 1450.

Obviously, Compton's tsuba has an altered nakago-ana and placed on the photo upside down. Compton's tsuba has a raised mimi, while mine does not.
