Antique Japanese Sword Wakizashi Signed by Masahiro with NTHK Kanteisho Certificate
【Description】
Summary
This blade was signed by Masahiro (正弘). And according to NTHK that authenticated this blade, it was made during the Eisho era (Late Muromachi period : 1504-1521). There were a few swordsmiths who used Masahiro as their maker’s names during this time and NTHK thinks it was made by Soshu Masahiro (相州正弘). This swordsmith is not the same as Masahiro (正広) while the pronunciation is the same. Soshu is the name of the province located in today’s Kanagawa prefecture.
When this blade was forged, Japan was in the warring state called Sengoku Jidai where there were so many rivalry and wars between regional feudal lords. It is possible this blade was owned by a Samurai who participated in one of the warfare back then. We believe it would be nice to have a piece that was forged in the warring state period.
This blade is categorized as a Koto blade. The swords made between the Late Heian Period towards the end of the Warring States (930-1595 A.D.) are called KOTO (古刀: Old-Sword) in Japanese. Those swords were likely to be used in real lives of Samurai, so their designs had to fit the way they used the sword. The blacksmithing technique wasn’t fully developed yet in this era, so the KO-TO blades contain gold, silver, and other metals, making the surface pattern of Koto intricate and beautiful.
Sunnobi Tanto (寸延び短刀)
In Japanese sword terminology, this blade is categorized as a Wakizashi because its cutting edge length is more than 30 cm long. However, it is much shorter than the average Wakizashi sword. And it is very close to the Tanto sword. This Tanto is called Sunnobi Tanto, a Wakizashi sword whose cutting edge is very close to the category of Tanto (Cutting edge less than 30 cm). And it must have been used as a Tanto back in the day.
What is Tanto?
It was initially used as a supplemental weapon for Samurai on horseback, who used a pole weapon or long sword in the Kamaura-Muromachi period. Samurai aimed at an unprotected area of his enemy’s armor with Tanto while having to fight with close distance.
TANTO was named accordingly, depending on how you carry it, such as HUTOKORO-GATANA (懐刀; Stomach-Sword) or KOSHI-GATANA(腰刀; Waist-Sword) or elsewise. TANTO was also a gift for a bride from her family in a traditional Japanese wedding, as it is believed that TANTO would be divine protection from evil power.
Soshu Den
Swordsmiths residing in Soshu province used 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.
At 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’t 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.
But, 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.
It 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. 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.
【 Blade】
Cutting Edge Length(Nagasa)： 32.0 cm (12.6 inches)
Curvature(Sori)： 0.3 cm ( 0.12 inches)
Hamon：
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
Jimon(Jihada)：
visible steel surface pattern created by folding and hammering during forging process
Nakago：Nakago 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).
According to NTHK, which appraised this Koshirae, it was made in the late Edo period.
Fuchi-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
This Fuchi Ksahira has different designs on each part. A kind of flower (probably chrysanthemum) patterns and Karakusa (唐草, arabesque) pattern are engraved on the Fuchi part. The Karakusa design is a pattern in which vine stems, and leaves 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. On the other hand, the Kashira part depicts a landscape. Although most colorings have already faded due to aging, golden colorings that seem to be brass inlays add decorativeness to this work.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
This Menuki depicts a man crossing a bridge, probably on the back of a horse or ox. It is a design that we could feel the connection with the landscape engraved on the Kashira part mentioned above.
Tsuba and Habaki：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.
You would find the figures of two Chou (蝶, butterfly) on the front of this Tsuba. People preferred the butterfly pattern due to its growth process, beauty, and auspiciousness among the various animal patterns. A larva becomes a chrysalis, and it grows up into a butterfly. Since this insect changes its looks, it symbolizes being reborn; therefore, Samurai loved this design. In this way, butterflies are seen as symbols of human life, death, and resurrection and are said to house the souls of the dead.
It is said that the butterfly pattern has been used since the Heian period (794-1185). This design was brought from the continent to Japan, and people introduced it in various fields. As proof of this, butterflies have also appeared in stories, such as the Heike-Monogatari (平家物語, The Tale of the Heike). This insect design gradually began to be used as a family crest, and it spread nationwide by being used by the Taira (平) clan. Taira-no Kiyomori (平 清盛, 1118-1181), who was the leader of the Taira family, used the Agehachou (揚羽蝶, swallowtail) crest. That is, it was treated as a symbolic design of the Heike (平家). According to a theory, about 300 Samurai used this motif for their family crests in the Edo period. It tells us the deep relationship between butterfly patterns and Samurai culture.
Kozuka：Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).
A Kogatana (小刀, small knife) is stored in the Kozuka. The surface of this Kozuka is decorated with the Nanako-Ji (魚子地) technique. This process makes a uniform minimal protrusions pattern by hitting the Nanako-Ji Tagane (魚子地鏨, a chisel for this technique) on a metal surface. This decorative technique is often seen on sword mountings. About the design, fishing tackles and a shrimp figure are engraved on it. For more information, please check the description of the scabbard.
Saya： Saya is the scabbard for the Japanese sword.
*Please keep in mind that there is a very tinny crack on this Saya. If you like to see the detailed condition please feel free to contact us.
The design of Kojiri (鐺, the metal fitting that protects the tip of a scabbard) of this scabbard is an Ebi (海老, shrimp).
Judging from the physiques of shrimps designed on these sword mountings, we believe these shrimps are the Iseebis (伊勢海老, spiny lobster). According to a theory, Japanese people already ate shrimp in the Heian period (794-1185). However, it was an expensive ingredient for ordinary citizens, so only the nobility and high-class people could enjoy it. People started using shrimp as a good-omen pattern and appreciated designing it for their family crests in the Muromachi period (1336-1573).
In the Samurai’s society, as shrimp is covered with a hard shell, it was thought that a shrimp represents the figure of a brave Samurai who wears armor. It has the meaning that wishes the fate of a Samurai will last for a long time. Shrimp has been likened to an older adult because of its long feelers. Also, shrimps actively jump even though they are bowed. That is the reason why the shrimp pattern is treated as a symbol of perpetual youth and longevity. This animal shed its molt several times to grow up; therefore, some people have considered it is a symbol of success in life.
