Modern Authentic Japanese Sword Tachi Signed by Izu Jyu Yusuishin Sadayoshi

【Description】

 This blade was signed by Izu Jyu Yusuishin Sadayoshi (伊豆住湧水心貞吉) 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.

 He 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.
In 1928, he started to work for Gassan Sadakatsu(月山貞勝) as an apprentice. His master’s father was Gassan Sadakazu(月山貞一), 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.

 He 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).

 Sadayoshi 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.
Gassan school’s origin dates back to the Kamakura period and one of the oldest Japanese swords that even exists today.

 He received awards in many exhibitions and was eventually designated as Mukansa swordsmith by NBTHK(Nihon Bijutsu Touken Hozon Kyokai). He left many great works until he died at the age of 92.

 You can observe his outstanding craftsmanship from this blade and feel the vitality he had. He survived during world war Ⅱ and kept forging swords for the rest of his life.

 Based on the registration paper, this blade was created as a Tachi sword. It comes with a Tachi(太刀) Koshirae.  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.

*What is Mukansa swordsmith?
 It is one of the most honorable titles a modern swordsmith could receive.
One 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.

About Modern Swordsmith
  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.
 Those who practice Iaido(居合道) tend to use those modern swords, and there are modern Japanese sword collectors nationwide.
The 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.

NakagoNakago is the tang of the Japanese sword.

 Japanese 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.

 

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).

 

Fuchi-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.

 The Kabutogane (冑金/兜金) is a metal fitting that is attached to the end of a handle. And a Sarute/Sarude (猿手) is attached to this Kabutogane. The user of a sword passed the Udenukio (腕貫緒, 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 (縁金物) is also a metal fitting attached to the handle, but on the opposite side of Kabutogane.

 This 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 (唐草, arabesque) pattern. Other sword mountings and metal fittings of this Koshirae have the same design, such as the Tsuba, Ishiduki Kanamono (石突金物, a fitting attached to protect the distal end of the scabbard), etcetera.

 The 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 (蔓) in Japanese and has another pronunciation; “Man.” There is a word 万 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read as “Tai.” Due to its pronunciation, the term “代 (Tai)” is associated. From this word-association game, an idiom 万代 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.

Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 This Menuki comprises one Kiku (菊, chrysanthemum) and two Kiri (桐, paulownia) patterns.

 A 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).  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 (菊の御紋) 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.

 The 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 (沢瀉, 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 (五七の桐文様); Go (五) means five, and Shichi (七) 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.

   
Tsuba and HabakiTsuba 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. 

 This Tsuba is categorized as the Kara Tsuba (唐鐔). This type of Tsuba was initially used for the Kara Tachi (唐太刀)-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 (分銅鐔) because its shape was similar to the Goto Hundou (後藤分銅, a type of weight) used in the Edo period.

*Please keep in mind that one side of the thin rounded metal is dented due to the damage in the past.

Saya Saya is the scabbard for the Japanese sword.  

 As mentioned above, the Kiku-no Gomon is applied to golden paint on this scabbard. It is also called the Kikka-Mon (菊花紋) or Kikka-Monsyou (菊花紋章). This design emphasizes the petals of chrysanthemums, and you would find sixteen petals.

 In the Kamakura period, the retired Emperor Gotoba (後鳥羽上皇, 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.

 On the opposite side of this scabbard, you would find that the Gosan-no-Kiri Monyou (五三の桐文様) 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 (鳳凰, Fenghuang, a kind of sacred beast) rests its wings at the paulownia tree; therefore, it has come to be regarded as a sacred plant.

Registration Number : Shizuoka 65879
