Modern Authentic Japanese Sword Tachi Signed by Izu Jyu Yusuishin Sadayoshi<\/strong><\/span><\/p>\n

\u3010Description\u3011<\/strong><\/span><\/p>\n

\u00a0This blade was signed by Izu Jyu Yusuishin Sadayoshi (\u4f0a\u8c46\u4f4f\u6e67\u6c34\u5fc3\u8c9e\u5409) in the 10th year of the Heisei era (1998), when he was 90 years old. Izu Jyu means that he resided in Izu city in Shizuoka prefecture when he forged this blade.<\/span><\/p>\n

\u00a0He was born in Tokushima(one of Shikoku island) in 1908. After finishing his primary education, he left his hometown and started to work at an iron factory in Osaka.<\/span>
\nIn 1928, he started to work for Gassan Sadakatsu(\u6708\u5c71\u8c9e\u52dd) as an apprentice. His master’s father was Gassan Sadakazu(\u6708\u5c71\u8c9e\u4e00), who was designated as a living national treasure in 1906. Sadayoshi started his career as a swordsmith by learning skills from one of the greatest swordsmiths.<\/span><\/p>\n

\u00a0He became an independent sword maker after his master’s death in 1943, moving to Mishima city in Shizuoka prefecture. He used special spring water coming from Mount Fuji to forge his swords. He called himself Yusuishi(A child of Spring Water) and signed this word before his signature(Sadayoshi).<\/span><\/p>\n

\u00a0Sadayoshi was excellent at forging Soshu-Den style swords There are so many great swordsmiths among Gassan school, but Sadayoshi was known as a specialist in forging and tempering.<\/span>
\nGassan school’s origin dates back to the Kamakura period and one of the oldest Japanese swords that even exists today.<\/span><\/p>\n

\u00a0He received awards in many exhibitions and was eventually designated as Mukansa<\/strong> swordsmith by NBTHK(Nihon Bijutsu Touken Hozon Kyokai). He left many great works until he died at the age of 92.<\/span><\/p>\n

\u00a0You can observe his outstanding craftsmanship from this blade and feel the vitality he had. He survived during world war \u2161 and kept forging swords for the rest of his life.<\/span><\/p>\n

\u00a0Based on the registration paper, this blade was created as a Tachi sword. It comes with a Tachi(\u592a\u5200) Koshirae.\u00a0 Tachi was mainly used by an armored Samurai with one hand on horseback from the Heian period (794-1185 A.D.) until the early Muromachi period. TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground. Because of its gorgeous looking, having a Tachi-style sword mounting became a social status among Samurai. We presume this sword mountings are antique ones.<\/span><\/p>\n

*What is Mukansa swordsmith?<\/span>
\n\u00a0It is one of the most honorable titles a modern swordsmith could receive.<\/span>
\nOne with this title could submit his work to the Japanese sword exhibition held by NBTHK(Nihon Bijyutu Touken Hozon Kyokai) without being examined. In contrast, other sword makers need to pass a rigorous test to participate in this event. This fact also suggests he was a great swordsmith in modern times. There are only 39 Mukansa swordsmiths now since the exhibition started in 1955. This exhibition is held by NBTHK once a year, and modern swordsmiths compete for their craftsmanship there.<\/span><\/p>\n

About Modern Swordsmith<\/strong><\/span>
\n\u00a0 There are around 150-200 swordsmiths in Japan today. To legally produce Japanese swords, one needs to pass the national exam given by the Agency for Cultural Affairs(Bunka-Cho) and receive the license. Before taking the exam, one must finish his or her apprenticeship under a licensed master for more than five years.<\/span>
\n\u00a0Those who practice Iaido(\u5c45\u5408\u9053) tend to use those modern swords, and there are modern Japanese sword collectors nationwide.<\/span>
\nThe modern Japanese sword makers are researching old ways to forge swords and trying to recreate ancient style swords. They are the ones who keep the tradition of Japanese history alive.<\/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

Koshirae:\u00a0Koshirae 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

\"\"<\/p>\n

 <\/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 Kabutogane (\u5191\u91d1\/\u515c\u91d1) is a metal fitting that is attached to the end of a handle. And a Sarute\/Sarude (\u733f\u624b) is attached to this Kabutogane. The user of a sword passed the Udenukio (\u8155\u8cab\u7dd2, a cord wrapped around the wrist to prevent a sword from falling out of the hand, mainly used when riding a horse) through this ring. And the Fuchi Kanamono (\u7e01\u91d1\u7269) is also a metal fitting attached to the handle, but on the opposite side of Kabutogane.<\/span><\/p>\n

\u00a0This Kabutogane and Fuchi Kanamono are decorated with the same design. It is a pattern of curved and intertwined vines. This design is called the Karakusa (\u5510\u8349, arabesque) pattern. Other sword mountings and metal fittings of this Koshirae have the same design, such as the Tsuba, Ishiduki Kanamono (\u77f3\u7a81\u91d1\u7269, a fitting attached to protect the distal end of the scabbard), etcetera.<\/span><\/p>\n

\u00a0The Karakusa pattern is a design 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 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 as \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, meaning 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.<\/span>
\n\"\"
\nTsuka and Menuki<\/strong><\/span>\uff1aTsuka is the handle of the Japanese sword and Menuki is its decoration.<\/b><\/span><\/p>\n

\u00a0This Menuki comprises one Kiku (\u83ca, chrysanthemum) and two Kiri (\u6850, paulownia) patterns.<\/span><\/p>\n

\u00a0A long time ago, the chrysanthemum was used as a medicine for obtaining a long life on the continent, and it was brought to Japan with this thought in the Nara period (648-781).\u00a0 Chrysanthemum symbolizes fall, and people have greatly appreciated it since ancient times. As its petals form radially, the chrysanthemum has been likened to the sun. That is why this flower pattern is treated as the symbol of perpetual youth and longevity or good health. The Kiku-no Gomon (\u83ca\u306e\u5fa1\u7d0b) is a kind of chrysanthemum pattern, and it has been used as the crest of the Emperor and the royal family in Japan, so it is well-known as a noble pattern. This Kiku-no Gomon is designed on the scabbard. Please check the enlarged photos of the sheath.<\/span><\/p>\n

\u00a0The paulownia pattern generally comprises three standing straight inflorescences and three leaves. The number of flowers blooming at each inflorescence shows the ranks of this design. It is also famous that one of the most popular Samurais in Japan: Toyotomi Hideyoshi used the Kiri pattern for his family crest. According to a theory, Hideyoshi used Omodaka (\u6ca2\u7009, arrowhead) pattern as his family crest. However, Oda Nobunaga, a well-known military commander in the Warring States period, permitted Hideyoshi to use Kiri design. his family crest is the Go-Shichi-no Kiri Monyou (\u4e94\u4e03\u306e\u6850\u6587\u69d8); Go (\u4e94) means five, and Shichi (\u4e03) means seven. If you focus on the number of flowers of each inflorescence in this Menuki’s paulownia, you will see that the flowers are attached in the order of five, seven, and five. It is more gorgeous than the similar patterns described later and is regarded as a higher-ranking pattern. Chrysanthemum and paulownia, both of which are elegantly made to order with high-class designs.<\/span><\/p>\n

\"\"\u00a0 \u00a0 \"\"
\nTsuba 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

\u00a0This Tsuba is categorized as the Kara Tsuba (\u5510\u9414). This type of Tsuba was initially used for the Kara Tachi (\u5510\u592a\u5200)-style Koshirae. The continental style changed to the Japanese style during the Heian period (794-1185), and it came to be applied to decorative swords for ceremonial purposes. The Kara Tsuba was also called the Hundou Tsuba (\u5206\u9285\u9414) because its shape was similar to the Goto Hundou (\u5f8c\u85e4\u5206\u9285, a type of weight) used in the Edo period.<\/span><\/p>\n

*Please keep in mind that one side of the thin rounded metal is dented due to the damage in the past.<\/span><\/em>
\n\"\" \"\"<\/p>\n

Saya<\/strong><\/span>\uff1a Saya is the scabbard for the Japanese sword.\u00a0\u00a0<\/strong><\/span><\/p>\n

\u00a0As mentioned above, the Kiku-no Gomon is applied to golden paint on this scabbard. It is also called the Kikka-Mon (\u83ca\u82b1\u7d0b) or Kikka-Monsyou (\u83ca\u82b1\u7d0b\u7ae0). This design emphasizes the petals of chrysanthemums, and you would find sixteen petals.<\/span><\/p>\n

\u00a0In the Kamakura period, the retired Emperor Gotoba (\u5f8c\u9ce5\u7fbd\u4e0a\u7687, 1180-1239) was particularly fond of chrysanthemum crests, and subsequent emperors inherited chrysanthemum crests as their own crests. It is said the chrysanthemum motif has been conventionally established as the crest of the imperial family.<\/span><\/p>\n

\u00a0On the opposite side of this scabbard, you would find that the Gosan-no-Kiri Monyou (\u4e94\u4e09\u306e\u6850\u6587\u69d8) is depicted. It is a popular design that the paulownia motif is used. This pattern was once used by the imperial family and people in authority at that time. Today, it is permitted to use by ordinary households and is appreciated as their family crests. According to a tradition, the Houou (\u9cf3\u51f0, Fenghuang, a kind of sacred beast) rests its wings at the paulownia tree; therefore, it has come to be regarded as a sacred plant.<\/span>

Registration Number : Shizuoka<\/span><\/span> 65879<\/span><\/span><\/strong><\/span><\/p>\n

\u00a0The Board of Education in Shizuoka prefecture issued a registration paper for this sword . It is called Jyu Token Rui Torokusho(\u9283\u5200\u5263\u985e\u767b\u9332\u8a3c). Bunkacho(The Agency for Cultural Affairs) acknowledges a Japanese sword with this paper as a work of art.
