Antique Japanese Sword Katana Signed by Minamoto no Masakage with <\/span>Tokubetsu Hozon<\/span> <\/span>Certificate<\/span>\u00a0<\/span><\/strong><\/p>\n \u3010Description\u3011<\/strong><\/span><\/p>\n \u00a0This blade was forged in December 1866 (the 2nd year of the Keio era) by Gotou Minamoto no Masakage (\u4e94\u5cf6\u6e90\u6b63\u9670)<\/strong>.<\/span><\/p>\n \u00a0Masakage was a disciple of Masao Minamoto (also known as Suzuki Masao), a distinguished student of the famous late Edo master Minamoto Kiyomaro, making Masakage effectively Kiyomaro\u2019s grand-disciple. Born as Gotou Koisuke in Etch\u016b Province (today\u2019s Toyama Prefecture), he first studied under Masao in Edo and later refined his skills under Suishinshi Masatsugu. He eventually established his forge in Takada Castle town (Echigo Province), producing blades that met the high demand during the turbulent Bakumatsu era. Masakage is categorized as a swordsmith of the Kiyomaro school; however, with the Meiji government\u2019s prohibition of swords, he had no choice but to abandon his career as a swordsmith.<\/span><\/p>\n \u00a0His signatures include \u201cMinamoto no Masakage,\u201d \u201cMasakage,\u201d \u201cGyokushinsai Masakage Saku,\u201d and \u201cGotou Minamoto Masakage.\u201d Inheriting the brilliant style of the Kiyomaro lineage, Masakage\u2019s swords are regarded as fine works with great potential value for future generations.<\/span><\/p>\n \u00a0Minamoto Kiyomaro (\u6e90\u6e05\u9ebf,<\/strong> 1813\u20131855) <\/strong>is remembered as one of the most outstanding swordsmiths of the late Edo period, often regarded as the greatest master of the Bakumatsu era. He was born into a g\u014dshi<\/em> (\u90f7\u58eb, farmer-samurai) family in Akaiwa village, Komoro domain (present-day T\u014dmi City, Nagano Prefecture). His real name was Yamaura Kur\u014dsuke Tamaki.<\/span><\/p>\n \u00a0Kiyomaro first studied under his elder brother, Yamaura Saneo, before moving to Edo, where he entered the dojo of Kubota Sugane, a martial arts instructor. Kubota soon recognized his true talent in swordsmithing and encouraged him to dedicate himself fully to the craft. Kiyomaro studied ancient masterpieces directly, borrowing swords from retainers, and strove to recreate practical, battle-ready blades.<\/span><\/p>\n \u00a0He strongly embraced the Revivalist Sword Theory (\u5200\u5263\u5fa9\u53e4\u8ad6, Token Fukko Ron), introduced by Suishinshi Masahide in 1826. This movement called for a return to the robust and practical forms of Kamakura-period blades, in contrast to the straighter and less powerful styles of his own day. The influence of this theory was so profound that Japanese swords are now historically divided into \u201cShint\u014d\u201d (New Swords, pre-Masahide) and \u201cShinshint\u014d\u201d (New New Swords, post-Masahide).<\/span><\/p>\n \u00a0Together with Suishinshi Masahide and his disciple Taikei Naotane, Kiyomaro came to be celebrated as one of the \u201cThree Great Edo Masters (Edo Sansaku).\u201d He later established his forge in Yotsuya, Edo, where he developed a distinctive style that fused elements of the S\u014dsh\u016b-den and Bizen-den traditions. His blades, with their brilliant nie<\/em> activity and bold, majestic form, were considered so remarkable that he was hailed as the \u201creincarnation of Masamune,\u201d earning him the enduring nickname \u201cYotsuya Masamune.\u201d<\/span><\/p>\n \u00a0Tragically, Kiyomaro\u2019s life ended in suicide at the age of 42, following a decline brought on by heavy drinking. Despite his short life, his dramatic story and extraordinary craftsmanship cemented his place in history. Today, Kiyomaro\u2019s swords remain among the most highly prized works on the market, admired as masterpieces that embody both the artistry and the spirit of the Bakumatsu era.<\/span><\/p>\n \u00a0Suishinshi Masahide (\u6c34\u5fc3\u5b50\u6b63\u79c0<\/strong>, 1750\u20131825)<\/strong> played an essential role in reshaping the sword-making world of the late Edo period.<\/span><\/p>\n \u00a0During his time, mainstream Japanese swords had become straighter and less robust compared to the masterpieces of the Kamakura era. By studying ancient swords, Masahide felt that something was lacking in contemporary blades. He therefore announced the Token Fukko Ron (Revivalist Sword Theory), declaring that swordsmiths should return to the old ways of forging. This theory deeply resonated with sword makers of the time and eventually became the mainstream of sword-forging.<\/span><\/p>\n \u00a0Masahide also wrote about ten books on swordsmithing and passionately trained many apprentices. Among his most famous students were Chounsai Tsunatoshi and Taikei Naotane, both of whom became renowned masters in their own right. His profound influence made him a central figure of the late Edo revival movement. He is counted as one of the Edo Sansaku (Three Great Edo Masters), together with Taikei Naotane and Minamoto Kiyomaro.<\/span><\/p>\n \u00a0In his biography, Masahide stated that he had forged 369 swords during his career. However, only about 100 of them have been identified in Japan today, most of which are wakizashi. It is extremely rare to find a katana signed by him, making such works highly valuable and historically significant.<\/span><\/p>\n <\/p>\n About late Edo period<\/strong><\/span><\/p>\n \u00a0The Bakumatsu period (\u5e55\u672b) was the final part of Japan\u2019s Edo period, lasting from around 1853 to 1868. It began when American ships led by Commodore Perry arrived in Japan and encouraged the country to open its ports to international trade. This moment was a turning point in Japanese history. Many people in Japan were surprised by Western technology and started thinking about how the country should respond to the changing world.<\/span><\/p>\n \u00a0At the time, there were strong debates between those who supported the traditional Tokugawa shogunate and others who believed Japan needed to modernize and return political power to the Emperor. These disagreements eventually led to conflict and the end of samurai-led government.<\/span><\/p>\n \u00a0Samurai were important figures during the Bakumatsu period. Their swords, known as Katana, were not just weapons but also powerful symbols of their values and way of life. However, as Japan began to build a modern army and adopt new weapons, swords became less common in battle.<\/span><\/p>\n <\/p>\n \u00a0<\/span>It is appraised as a Tokubetsu Hozon Token <\/strong>(\u7279\u5225\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, especially well preserved and high quality with artistic value.<\/span><\/p>\n <\/p>\n *Please keep in mind that there is a couple of Kitae Kizu on the Mune.

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\uff1aKoshirae 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 \u00a0<\/span> <\/p>\n Fuchi-Kashira<\/strong><\/span>\uff1aA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.<\/span><\/strong><\/p>\n \u00a0The motif of this Fuchi-Kashira appears to represent the \u201cSeven Flowers of Autumn\u201d (\u79cb\u306e\u4e03\u8349, Aki no Nanakusa), delicately expressed in fine gold inlay. In Japanese culture, the Seven Flowers of Autumn are deeply associated with classical literature and poetry, especially the Manyoshu (the oldest anthology of Japanese poems). They were admired not for eating but for their beauty and for the way they symbolize the seasonal transition from summer to autumn. By adorning sword fittings with such motifs, samurai not only enjoyed their refined aesthetic but also carried with them symbolic wishes for resilience, purity of spirit, and dignity in life.<\/span><\/p>\n \u00a0The tradition of admiring the Seven Flowers of Autumn was a form of seasonal appreciation. In ancient Japan, people would stroll through flower fields and compose poems (waka and haiku) inspired by their beauty. The origin of this custom is attributed to two poems by the Nara-period poet Yamanoue no Okura (660\u2013733), which are preserved in the Manyoshu. From these verses, the appreciation of the Seven Flowers of Autumn became an enduring part of Japanese seasonal culture.<\/span><\/p>\n Tsuka and Menuki<\/strong><\/span>\uff1aTsuka is the handle of the Japanese sword and Menuki is its decoration.<\/b><\/span><\/p>\n \u00a0The motif of this Menuki is a dragon (\u9f8d, Ry\u016b).<\/span><\/p>\n \u00a0The dragon was originally an imaginary creature from ancient Chinese traditions and myths. It is considered a symbolic beast of auspicious signs. Its body is described as a combination of nine animals: antlers of a deer, the head of a camel, eyes of a demon, the neck of a snake, the belly of a Mizuchi (a Japanese mythical creature resembling a horned, four-legged serpent), scales of a fish, claws of a falcon, palms of a tiger, and ears of a cow. Because of this extraordinary form, the dragon was believed to reign at the top of all creatures.<\/span><\/p>\n \u00a0In ancient China, dragon motifs were used exclusively for the emperor\u2019s clothing, with strict rules regarding the design and even the number of claws. In Japan, however, such rigid regulations did not exist, and the dragon motif was widely used while still retaining its meaning as an all-purpose auspicious design.<\/span><\/p>\n \u00a0In addition, in Japan the dragon is also revered as a water deity, known as Ry\u016bjin Shink\u014d (\u7adc\u795e\u4fe1\u4ef0). Since rice cultivation has always depended on water, the dragon became a familiar and powerful symbol deeply connected to Japanese life and culture.<\/span><\/p>\n Tsuba and Habaki<\/strong><\/span>\uff1aTsuba 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<\/span><\/strong><\/p>\n \u00a0The design of this tsuba\u00a0features a hexagonal geometric pattern crafted using the technique known as sukashi-bori (\u900f\u304b\u3057\u5f6b\u308a, openwork carving). Sukashi-bori involves cutting through the surface of the metal to create open spaces, allowing a hard material like iron to be expressed in a delicate and airy form. Light and shadow interplay through the openings, producing a striking visual effect.\u00a0Beyond its decorative appeal, this technique also served practical purposes, such as reducing the overall weight of the guard and distributing structural stress during use.<\/span><\/p>\n Saya<\/strong><\/span>\uff1aSaya is the scabbard for the Japanese sword.\u00a0\u00a0<\/strong><\/span>\u00a0<\/span><\/p>\n \u00a0<\/span> \u00a0\u00a0NBTHK<\/a><\/span><\/span>, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan. They authenticated the blade on March 10th in the 5th year of Reiwa (2023). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file<\/span><\/a><\/span> for your record if you request.<\/span><\/p>\n Registration Number : Shizuoka 18466<\/span><\/span><\/strong><\/p>\n \u00a0The Board of Education in Shizuoka prefecture issued a registration paper for this sword. It is called Jyu Hou Token Rui Tourokusho (\u9283\u7832\u5200\u5263\u985e\u767b\u9332\u8a3c).
