Antique Japanese Sword Wakizashi Signed by Omi no Kami Tadatsuna with Tokubetsu Hozon<\/span>\u00a0Certificate<\/span><\/span><\/strong><\/p>\n \u3010Description\u3011<\/strong><\/span><\/p>\n \u00a0This blade was signed by Awataguchi Omi no kami Tadatsuna (\u7c9f\u7530\u53e3\u8fd1\u6c5f\u5b88\u5fe0\u7db1) in the 12th year of the Genroku era (1699:early-mid Edo period). The maker\u2019s name Tadatsuna lasted a few generations, and based on the active period of the generations, we believe it was signed by the second-gen. The second-gen Tadatsuna was active in the early-mid Edo period (Late 17th century), and he is one of Osaka\u2019s most skilled and popular swordsmiths in the early Edo period, following Tsuda Sukehiro and Inoue Shinkai. These three sword makers are called Sanketsu of Osaka Shinto.<\/span><\/p>\n \u00a0The second-gen Tadatsuna was born in 1644 as the first son of the first-gen Tadatsuna, who called himself the descendant of Awataguchi Kunitsuna, a famous swordsmith in the early Kamakura period. Father was born in Hyogo prefecture and forged swords in Ushiroyama castle in Mie prefecture. <\/span>Eventually, the first-gen Tadatsuna moved to Settsu province (<\/span>Osaka).\u00a0<\/span><\/p>\n \u00a0The second-gen Tadatsuna’s real name is Asai Mandayu. The swordsmith’s name Tadatsuna lasted three generations, and the second-gen is said to have been the most famous and skilled one. And he was not only excellent at forging swords with different kinds of tempering lines (Hamon) but also excellent at inscribing sculptures on his work.<\/span><\/p>\n \u00a0The second-gen Tadatsuna first signed as Tadakuni(\u5fe0\u56fd). According to his remaining work, he started to forge swords in 1672 and kept creating his blades until he was about 80 years old(1716). He received the honorable title of Omi no Kami during the Enpo era(1673-1680). He changed how he signed and started to write Ikkanshi Tadatsuna (\u4e00\u7aff\u5b50\u5fe0\u7db1) after the second year of Genroku era(1689). <\/span><\/p>\n \u00a0During the early Genroku era, he used \u7e04 letter instead of \u7db1 when signing his creation, but after the mid-Genroku era, he used \u7db1 to sign his blades. Genraoku period lasted 1688-1704.He kept forging swords for about 50 years in his career.<\/span><\/p>\n \u00a0One of Tadatsuna’s works is designated as Important Cultural Property of Japan. His swords are Ryuwazamono and Shinto Jyojyo Saku(Highly ranked swords among Japanese sword experts).<\/span><\/p>\n \u00a0There is one interesting historical incident related to the work of the second-gen Tadatsuna. <\/span>It was March 24th in the 4th year of Tenmei(1784). Sano Zenzaemon, A direct retainer of Shogun, attacked a son of Tanuma Okitsugu, who was the chief minister of the Edo government. Sano used a wakizashi signed by the second-gen Tadatsuna. The son was eventually died, and Sano was ordered to do Seppuku for his misconduct. <\/span><\/p>\n \u00a0Interestingly, since this incident happened, the price of rice decreased dramatically after the sharp rise, which suffered many people. And, people started to worship Tadatsuna’s swords as Yonaoshi Daimyojin, a Great God that makes the world a better place. The Tadatsuna’s popularity skyrocketed, and this incident is much talked about when you learn about the work of Tadatsuna. It is said that only noble high-class Samurai could afford to buy a sword forged by the Tadatsuna during the Edo period.<\/span><\/p>\n <\/p>\n \u00a0It 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 are a couple of Kitae Kizu as well as a tiny chip. If you like to know the detailed condition, please feel free to contact us.<\/span><\/em><\/p>\n <\/p>\n \u3010Blade\u3011<\/span><\/strong> Hamon<\/strong><\/span>\uff1a Kissaki<\/strong>\uff1a<\/span><\/span>Kissaki is the tip\u00a0of the Japanese sword.<\/strong><\/span>\u00a0<\/span><\/p>\n Nakago<\/strong><\/span>\uff1aNakago is the tang of the Japanese sword. <\/strong><\/span><\/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>\uff1a<\/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 \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 This Fuchi-Kashira has a simple, restrained design. A deep black surface is paired with a warm brown area that runs diagonally across it, creating a clean contrast. With no detailed ornament, the finish and the quiet balance of the two tones stand out.<\/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 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 motif of this tsuba is an openwork design of sawarabi-karakusa (\u65e9\u8568\u5510\u8349, bracken-and-arabesque). Thick, vine-like lines flow in a continuous rhythm across the circular frame, creating the familiar movement of karakusa (\u5510\u8349). At several points the tips curl tightly into small spirals, like unfurling bracken shoots (\u65e9\u8568, sawarabi), which gives the pattern a lively, springlike feel. The composition balances bold curves with empty space, so the design reads clearly while still feeling dynamic and organic.<\/span><\/p>\n \u00a0Sawarabi (\u65e9\u8568) means a young bracken fern shoot that appears in early spring. Bracken shoots have a distinctive curled tip, like a small spiral, before they fully open into leaves. In Japanese design, this shape is used as a symbol of spring, new beginnings, and fresh energy, because it suggests something growing and unfolding.<\/span><\/p>\n \u00a0Karakusa is is a pattern in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (\u8513) in Japanese, and it has another pronunciation; \u201cMan.\u201d There is a word \u4e07 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (\u5e2f, belt). The word \u201c\u5e2f\u201d can also be read \u201cTai.\u201d Due to its pronunciation, the term \u201c\u4ee3 (Tai)\u201d is associated. From this word-association game, an idiom \u4e07\u4ee3 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.\u00a0<\/span><\/p>\n Kozuka<\/strong><\/span><\/strong>\uff1aKozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).<\/b><\/p>\n \u00a0<\/span><\/p>\n <\/p>\n Kougai<\/strong><\/span><\/strong>\uff1aKougai is the equipment for Samurai to arrange or fix his hair style.<\/strong><\/p>\n <\/p>\n Saya<\/strong><\/span>\uff1aSaya is the scabbard for the Japanese sword.\u00a0\u00a0<\/strong><\/span><\/p>\n \u00a0This scabbard is covered with black lacquer. Due to its high waterproof effect, lacquer has been used since ancient times in Asia. The blade of a Japanese sword is made of iron, and moisture is the greatest enemy of iron. For the purpose of carrying the blade without degrading it, people devised a method of coating the scabbard with lacquer. To prevent not only moisture but also rain and snow from penetrating the inside of the scabbard, it was necessary to apply multiple layers of lacquer. The Nushi (\u5857\u5e2b, lacquerers) was born precisely because advanced techniques were required to handle the complicated processes.<\/span><\/p>\n Authentication Paper<\/strong><\/span>\uff1aNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1024060)<\/strong><\/span><\/p>\n \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 Feb 21th in the 7th year of Reiwa (2025). 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 : <\/span>Gifu 3024<\/span><\/span><\/strong><\/p>\n \u00a0The Board of Education in Gifu issued a registration paper for this sword. It is called Jyu Hou Token Rui Tourokusho (\u9283\u7832\u5200\u5263\u985e\u767b\u9332\u8a3c).
