Tachi: in Shirasaya with Koshirae (25th NBTHK Juyo Token)
\nSignature: Senjuin
\n\u5343\u624b\u9662<\/p>\n

Sayagaki: Yamato Senjuin. A rare signed work.
\nBlade length: 2 shaku 3 sun 4 bu. Written by Kunzan in the month of Chogetsu, the year of Kinoto-U, Showa (1975)\u3000Kunzan (Kao).<\/p>\n

Koto: Jyo Saku: Yamato
\nWe classify swords into Saijyo Saku, Jyojyo Saku, Jyo Saku, and Regular Saku based on the swordsmith’s skill.
\nAmong Senjuin works, this piece is ranked as Saijyo Saku.<\/p>\n

Habaki: Gold-covered single-layer.
\nBlade length: 70.8 cm (27.87 in)
\nCurvature (Sori): 1.5 cm (0.59 in)
\nMekugi-ana (peg hole): 2
\nWidth at Base (Motohaba): 2.78 cm (1.09 in)
\nWidth at Tip (Sakihaba): 1.59 cm (0.63 in)
\nKasane (thickness): 0.80 cm (0.31 in)
\nBlade weight: 625 grams
\nEra: Early Kamakura period, around the Ken’ei era.<\/p>\n

Shape: The blade is somewhat wide, with deep curvature and a slightly extended kissaki.
\nJudging from the curvature, the blade is considered to retain almost its original ubu form.<\/p>\n

Jigane: Chikei appears, the grain stands out, and utsuri manifests.
\nThe shinogi-ji shows a mixture of itame hada, masame hada, and mokume hada, conveying a sense of great age.<\/p>\n

Hamon: The hamon is suguha.
\nThe nioiguchi is deep, with fine sunagashi and kinsuji working actively throughout.<\/p>\n

Features:
\nThe Senjuin Washu school was not a single swordsmith but is believed to have consisted of several smiths.
\nWhile many mumei attributions to Senjuin are recorded in the Kanto Hibisho, only one signed work is known to exist. That very sword is the piece introduced here.
\nIt appears on pages 407 and 408 of the Kanto Hibisho, Zoku (Sequel).<\/p>\n

According to the book:
\n“The blade is slender with a ko-kissaki, but the koshi-zori is high, with good tapering (funbari), and a high shinogi.
\nThe forging is itame nagare, with masame and chikei mixed in.
\nThe hamon is nie-deki, a chu-suguha with ko-gunome-midare and hotsure mixed in, with sunagashi and kinsuji.
\nThe boshi returns deeply and roundly, with strong nie, somewhat crumbling in character, but with strong hakikake.
\nThe nakago is ubu, with a broken-up upper edge (saki-yabure) and a kurijiri, the ha-side gently rounded, and the yasurime indistinct.
\nThe signature is somewhat buried in rust but is read as ‘Senjuin,’ and as is customary, the chisel strokes are rather thick.
\nFrom the above workmanship, there is no doubt that this is Yamato Senjuin, and the period should be regarded as around the same time as Kanenaga, roughly the mid-Kamakura period.
\nAlthough there is some fatigue, signed Senjuin works are extremely rare, giving this piece high documentary value.”<\/p>\n

This was a favorite of the late Reverend Hashimoto Dokuzan of Shokoku-ji, and we believe it was one of the reverend’s cherished swords.
\nIt is a truly precious signed work.
\nIt is a piece from before the mid-Kamakura period, with a character quite distinct from that of the Bizen smiths.
\nWe highly recommend it.<\/p>\n

Koshirae:
\nTsuba: Mokko-shaped shakudo nanako-ground tsuba carved with clouds and a dragon, highlighted with gold iroe.
\nFuchikashira: Shakudo ground with a dragon in high relief, decorated with gold iroe.
\nKurikata: Shakudo ground.
\nSaya (Scabbard): An exceptionally well-crafted aogai-chirashi saya.
\nMenuki: Dragon in high relief.<\/p>\n

Aoi Art’s Comment:
\nAs you may know, almost all Senjuin works are mumei attributions.
\nWhile many mumei Senjuin attributions are recorded in the Kanto Hibisho, only one signed work exists, and that very sword is the piece introduced here.
\nConsequently, any works evaluated hereafter will have no choice but to refer to and be judged against the mumei attributions.
\nBy using this elegantly shaped, ubu, signed work as a reference for the hamon\u2014particularly by carefully studying its many distinctive features such as the boshi hotsure, the descending hakikake and the character of the hamon, and the niju-ha\u2014we believe everyone can gain a full understanding of what a Senjuin work is.
\nAmong Juyo Token, this can be said to be the oldest and most clearly demonstrated example of a three-character Senjuin signature.
\nBoth the sword and the koshirae have been carefully preserved, and it was most likely handed down by a famous daimyo.<\/p>\n
