The jigane features a well-compacted itame-hada with visible chikei. The hamon displays fine, orderly gunome patterns, and the niokuchi is tightly defined. Kin-sen is also visible within the hamon. Although this is an unsigned sword, Sato Kanzan, an authority on Japanese sword appraisal, identified it as a work by Ko-yoshii during the Year of the Rabbit in the Showa era and inscribed the scabbard. The Year of the Rabbit in the Showa era can be presumed to be either 1951 or 1963.\u003c\/p\u003e\n\u003cp\u003eThe Yoshii school is a group of swordsmiths descended from Noritsune, who forged swords on the opposite bank of the Yoshii River in Bizen, across from Osafune Village, from the late Kamakura period onward. Swords from the late Kamakura period through the Nanbokucho period are referred to as “Ko-yoshii.” On the other hand, in December 2023, the Society for the Preservation of Japanese Art Swords certified this as a work by Toshinaga.\u003c\/p\u003e\n\u003cp\u003eToshinaga refers to a school of swordsmiths active from the late Kamakura period through the end of the Edo period in Mino Province (present-day Gifu Prefecture) and other regions. Because the kanji for “Toshinaga” can also be read as “Jumyo” (meaning “long life”), the name was considered auspicious, making these swords highly prized among the samurai class as gifts or celebratory items. While their style draws from the Yamato tradition, they possessed a wide range of techniques. They are characterized by the powerful jigane and hamon typical of Mino-period works.\u003c\/p\u003e\n\u003cp\u003eWhy not add this unique katana, which holds two different appraisals, to your collection?\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBlade length: 72.0 cm\u003c\/li\u003e\n\u003cli\u003eCurvature: 1.6 cm\u003c\/li\u003e\n\u003cli\u003eNumber of Mekugi hole: 2\u003c\/li\u003e\n\u003cli\u003eSakihaba: 19.8 mm\u003c\/li\u003e\n\u003cli\u003eSakikasane: 4.6 mm\u003c\/li\u003e\n\u003cli\u003eMotohaba: 30.4 mm\u003c\/li\u003e\n\u003cli\u003eMotokasane: 6.4 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSignature: No signature\u003c\/li\u003e\n\u003cli\u003eEra: Koto\u003c\/li\u003e\n\u003cli\u003eStructure: Shinogi-zukuri, Iori-mune\u003c\/li\u003e\n\u003cli\u003eJigane:Itame\u003c\/li\u003e\n\u003cli\u003eHamon: Ko-gunome\u003c\/li\u003e\n\u003cli\u003eBoshi: Midarekonde Omaru ni Kaeru\u003c\/li\u003e\n\u003cli\u003eWeight: 710 g(blade only)\u003c\/li\u003e\n\u003cli\u003eNakago: Ubu\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eKoshirae: Shirasaya\u003c\/li\u003e\n\u003cli\u003eOriginal Registration No.: Tokyo 214438\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003ePlease \u003ca href=\"https:\/\/japanesesword.net\/pages\/antique-japanese-sword-katana-wanted-form\" title=\"Please contact us if the katana you are looking for is not listed here\" target=\"_blank\"\u003econtact us\u003c\/a\u003e if the katana you are looking for is not listed here.\u003c\/p\u003e","brand":"TOZANDO KATANA SHOP","offers":[{"title":"Default Title","offer_id":53310758977899,"sku":"C001-ATQSWD-Tokyo214438","price":798000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/2178\/8069\/files\/tokyo214438_mumei_9.jpg?v=1780369700","url":"https:\/\/japanesesword.net\/products\/authentic-koto-era-katara-for-sale-mumei-nbthk-hozon-certificatetoshinaga-tozando","provider":"Tozando Katana Shop","version":"1.0","type":"link"}
