Antique Japanese Sword Katana attributed to Shimada with NBTHK Hozon<\/span> Certificate<\/strong><\/span><\/p>\n \u3010Description\u3011<\/strong><\/span><\/p>\n \u00a0This blade is attributed to the Shimada school. The school was founded by Yoshisuke (\u7fa9\u52a9) in the mid-Muromachi period and continued until the late Edo period. According to the appraisal by the NBTHK<\/span><\/span>, this blade was forged during the Shint\u014d period (1596\u20131780), spanning from the Azuchi\u2013Momoyama period to the mid-Edo period.<\/span> The group of Shimada swordsmiths resided in Shimada city, Suruga province (today\u2019s Shizuoka prefecture). Other famous swordsmiths from this school are Sukemune, Hirotsugu, and Sadahiro.<\/span><\/p>\n \u00a0The first-gen Yoshisuke was active during the Kosho era (1455-57). It is said that the first-gen Yoshisuke was a descendant of Bizen Ichimonji Sukemune, one of the most famous swordsmiths in Japanese history. The first-gen Yoshisuke served a powerful feudal family named Imagawa. It is said that he received his maker\u2019s name \u7fa9 from Imagawa Yoshitada.<\/span><\/p>\n \u00a0Shimada school interacted with other schools in Soshu swordsmiths living near Odawara castle in Kanagawa prefecture. The Suruga domain was vital for strong feudal lords such as Takeda, Tokugawa, and Hojo clan during the Sengoku Jidai (Warring state period: Late Muromachi period). The swordsmiths in Shimada school received many orders from these powerful feudal families. The first-gen Yoshisuke had mastered excellent craftsmanship, and it was passed down to swordsmiths in Shimada school.<\/span><\/p>\n Soshu Den<\/strong><\/span><\/p>\n \u00a0It is said that the generations of Sukemune\u00a0 mastered\u00a0 a particular sword-forging tradition called Soshu Den. Shoshu Den was born in the middle of the Kamakura period. Back then, the Yamato and Yamashiro traditions were highly developed, and there were a few renowned swordsmiths from those regions. However, the sword-forging practice was in its infancy in the Kanto area, where the Soshu region was located.<\/span><\/p>\n \u00a0At the beginning of the Kamakura government, which was established in 1185, the first Shogun, Minamoto Yoritomo, prioritized making a lot of rules to have its political stability. And he couldn\u2019t afford to hire swordsmiths within the same region or train them. Therefore, the Kamakura government originally ordered weapons to the swordsmiths in the other areas, such as Yamato and Yamashiro.<\/span><\/p>\n \u00a0But, since the government was established, the demand for weapons increased exponentially in the government, and they had to figure out how to meet those demands from Samurai who served Kamakura shogunate. Then, the 5th head of the Shogun, Hojo Tokiyori, invited two renowned swordsmiths from other parts of Japan. They were Awataguchi Kunitsuna from Yamashiro province and Bizen Saburo Kunimune from Bizen province. And the 7th-gen Shogun Koreyasu Shino also invited Fukuoka Ichimonji Sukezane from Bizen province.<\/span><\/p>\n \u00a0It is said that those three swordsmiths played an essential role in creating the Soshu Den and making the foundation of the Soshu Den. Also another famous figure in the Soshu den is Intou Kunimitsu, an adopted son of Awataguchi Knitsuna. And Kunimitsu passed his excellent craftsmanship to Yukimitsu, his apprentice. And Masamune, one of the most famous swordsmiths in Japanese history, was an apprentice of Yukimitsu.\u00a0 And Masamune was the one that brought Shoshuden to nationwide fame. The tradition Masamune completed became an example of other swordsmiths who learned Soshu Den. Also, Soshu Den influenced many renowned swordsmiths during the Koto- Shinto era. One of examples is Inoue Shinkai from Osaka and Suishinshi Masahide from Edo.<\/span><\/p>\n <\/p>\n \u00a0This blade is appraised as a Hozon Touken <\/strong>(\u4fdd\u5b58\u5200\u5263) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai: \u65e5\u672c\u7f8e\u8853\u5200\u5263\u4fdd\u5b58\u5354\u4f1a). This authentication paper was only given to authentic Japanese swords, well preserved and high quality with artistic value.\u00a0<\/span><\/p>\n <\/p>\n *Please keep in mind that there are a couple of\u00a0 Kitae Kizu as well as minor crack on the blade. If you like to see the detailed condition, please feel free to contact us.<\/em><\/span><\/p>\n <\/p>\n \u3010Blade\u3011<\/span><\/strong> Hamon<\/strong>:\u00a0<\/span><\/span> Kissaki<\/strong>: <\/span><\/span>Kissaki is the tip\u00a0of the Japanese sword.<\/strong><\/span><\/p>\n Nakago<\/strong><\/span>: Nakago is the tang of the Japanese sword.<\/strong><\/p>\n \u00a0Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.<\/span><\/p>\n <\/p>\n Koshirae<\/strong>:<\/span> Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya (Scabbard), Tsuka (Handle), Tsuba (Handguard).<\/span><\/strong><\/span><\/p>\n \u00a0The primary motif of this Koshirae is the Ry\u016b (\u9f8d, dragon). Throughout the fittings, the classic Unry\u016b-zu (\u96f2\u9f8d\u56f3, dragon emerging from clouds) design is prominently featured.<\/span><\/p>\n \u00a0The dragon is an imaginary creature originating in ancient Chinese mythology and has long been revered as a symbol of auspicious power. Its form is traditionally described as a composite of nine animals: antlers of a deer, a camel\u2019s head, demon-like eyes, a snake\u2019s neck, the belly of a mizuchi (\u86df, a mythical Japanese water creature resembling a horned serpent), fish scales, falcon-like claws, tiger-like paws, and the ears of an ox. Because of this extraordinary and otherworldly appearance, the dragon was believed to reign supreme over all animals.<\/span><\/p>\n \u00a0 In ancient China, the dragon motif was strictly reserved for the emperor, and even details such as its form and the number of claws were carefully regulated according to rank. In contrast, Japanese representations of dragons were not governed by rigid class-based rules. Nevertheless, the motif retained its significance as a universally auspicious symbol, associated with power, protection, and good fortune.<\/span><\/p>\n \u00a0In Japan, dragons have also been venerated as water deities under the belief known as Ry\u016bjin Shink\u014d (\u7adc\u795e\u4fe1\u4ef0, dragon-god worship). As rice cultivation has long been central to Japanese society, water has always been an essential and sacred resource. For this reason, the dragon motif\u2014symbolizing rain, water, and life-giving force\u2014has been deeply familiar to the Japanese people since ancient times.<\/span><\/p>\n <\/p>\n Fuchi-Kashira<\/strong>: A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.<\/strong><\/span><\/p>\n \u00a0This Fuchi-Kashira features a Cloud and Dragon motif (Unryu-zu, \u96f2\u7adc\u56f3), a powerful design symbolizing strength, protection, and divine authority.\u00a0<\/span><\/p>\n \u00a0In Japanese art, the dragon is regarded as a benevolent and celestial creature associated with water, rain, and the heavens, while clouds signify the realm from which divine power emerges. Together, the cloud-and-dragon motif conveys vitality, auspicious energy, and spiritual protection, making it a favored subject among samurai and craftsmen alike.<\/span><\/p>\n \u00a0The material used is shakud\u014d nanako-ji (\u8d64\u9285\u9b5a\u3005\u5b50\u5730). Shakud\u014d is a traditional Japanese alloy composed primarily of copper with a small amount of gold. It is known for developing a rich, bluish-black patina when treated, giving it a deep, elegant finish. The term nanako-ji refers to a finely punched background texture resembling fish roe, often used in high-quality sword fittings to add refinement and visual depth.<\/span><\/p>\n Tsuka and Menuki<\/strong>: Tsuka is the handle of the Japanese sword and Menuki is its decoration.<\/b><\/span><\/p>\n \u00a0<\/span> Tsuba and Habaki<\/strong>: Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.\u00a0<\/strong><\/span><\/p>\n Kozuka<\/strong><\/strong>: Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).<\/b><\/strong><\/p>\n <\/p>\n <\/p>\n Kougai<\/strong>:<\/span> <\/span>Kougai is the equipment for Samurai to arrange or fix his hair style.<\/strong><\/p>\n <\/p>\n Saya<\/strong>: <\/span>Saya is the scabbard for the Japanese sword.\u00a0<\/strong>\u00a0<\/strong><\/span><\/p>\n *Please note that there is a surface wear on this saya.
