\nFeatures: This work is an excellent piece by Ch\u014dunsa\u00ef Emura.
\nUsually he signed simply \u201cEmura\u201d or \u201cEmura saku,\u201d but particularly carefully made works bear the long signature \u201cCh\u014dunsa\u00ef Emura saku.\u201d
\nEmura served as the director of Okayama Prison during the war, and it is said that there was a large-scale Japanese sword production workshop inside the prison.
\nThe makers were selected from among well-behaved prisoners serving long sentences, and under the director\u2019s supervision they devoted themselves to sword production.
\nPolishing was also carried out in the same workshop, resulting in well-polished blades.
\nIn the past, Nagamitsu and Emura were often confused.
\nHe was born in Tokushima Prefecture and died in 1960.
\nHis workmanship differs from that of Nagamitsu and appears to be of even higher quality.
\nI have long paid attention to his works, and while Nagamitsu produced many swords with some variation in quality, nearly all of Emura\u2019s works are above standard, and some surpass even Yasukuni swords in quality.
\nThese works will attract increasing attention in the future.
\nIt is said that the quenching and signature engraving were always performed by Director Emura himself, and the signatures include \u201cEmura,\u201d \u201cEmura saku,\u201d and \u201cCh\u014dunsa\u00eft\u014d Emura saku.\u201d<\/p>\n

Koshirae:
\nTsuba: Suaka plate tsuba carved with birds by the waterside.
\nFuchikashira: Shakudo nanako ground carved with waterside birds and finished with gold iroe.
\nSaya (Scabbard): Black roiro lacquered saya.
\nMenuki: Shakudo ground with high-relief chrysanthemums, finished with gold iroe.<\/p>\n

Aoi Art\u2019s Comment: After a long time, a long-signature Emura blade has appeared.
\nMr. Emura, the director of Okayama Prison, was as described above.
\nTherefore, because polishing was also performed there, many of his works are of high quality and in good condition.
\nThis piece can be regarded as one of Emura\u2019s masterpieces, solidly made, with a particularly gorgeous hamon of deep nioiguchi gunome-midare mixed with choji-midare.
\nThe ashi are gently formed, creating an atmosphere as if drifting in mist.
\nIt is an outstanding work that could easily be mistaken for a high-quality Shinshinto Jyo Saku blade, and if submitted for appraisal, it would astonish the judges.
\nHistorical Background: Made during wartime, and bearing a long signature, it is an especially carefully crafted sword.<\/p>\n
