Antique Japanese Sword Katana Signed by Yasuyoshi with Tokubetsu Hozon Certificate
This blade was signed by Bushu Jyu Yasuyoshi (武州住安儀), who was especially active during the Enpo era (Early Edo period: 1673-1681). Bushu Jyu means that he lived in Bushu domain (today’s Tokyo). He was an apprentice of Yamato no Kami Yasusada (大和守安定), one of the most famous swordsmiths in the early Edo period.
It is said that Yasuyoshi regularly did Daisaku for his master, Yasusada. That means that his master highly acknowledged Yasuyoshi’s craftmanship. Daisaku is a regular act where an apprentice or a child of the swordsmith signed his master’s name with his master’s permission or forged a blade on behalf of the master. That is also why there aren’t many remaining blades signed by Yasuyoshi, who dedicated his career to helping his master.
We also presume that Yasuyoshi might have received his sword maker’s name “安(Yasu)” from Yasusada.
Yamato no Kami Yasusada (His master)
Yamato no Yasusada belonged to Kishu Ishido School, one of Ishido school’s branches. Ishido school was initially founded by Sukenaga, an offspring of Ichimonji Sukemune, who had created Fukuoka Ichimonji school in Bizen province(Today’s Okayama prefecture).
During 1492-1501 (Mid Muromachi period), Sukenaga and his school moved from Bizen province to Omi province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido.
As of the early Edo period, many Ishido swordsmiths in Omi province moved to other parts of Japan. Four major branches flourished: Edo, Osaka, Kishu(Wakayama prefecture), and Chikuzen(Fukuoka prefecture). Following this trend, Yasuhiro, a prominent figure in Omi Ishido school and the father of Yasusada, moved to Kishu province from Omi province. It is said that Yasuhiro was the founder of Kishu Ishido school. In his early career, Yasusada served Kishu domain with his father.
In the third year of the Shouho era (1646), Yasuhiro and Yasusada moved to Edo city. Since then, Yasusada lived in Edo city, working under prominent swordsmiths, such as the third-gen Yasutsugu and Izumi no Kami Kaneshige.
Considering Yasusada was a renowned swordsmith, letting Yasuyoshi forge blades on his behalf, we believe Yauyoshi was also a high-skilled swordsmith. This blade also comes with beautiful auspicious dragon-themed sword mounting.
This blade is appraised as a Tokubetsu Hozon Token(特別保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, especially well preserved and high quality with artistic value.

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).
Fuchi-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
The whole sword mounting has dragon design. Initially, the dragon is an imaginary creature found in ancient foreign traditions or myths. Furthermore, it is regarded as a symbol of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is the Mizuchi (蛟, a mythical animal in Japan that looks like a snake and has a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
As mentioned above, this Menuki’s motif is also the dragon. The entire of this Menuki is colored with golden paint and remains this coloring relatively in good condition. In Japan, there is a belief that worships a dragon as a water god. Since rice cultivation has flourished in this country, water is always an essential resource. Therefore, the dragon motif has been familiar to Japanese people for a long time. Understandably, this dignified beast motif is seen in many sword mountings. It shows lots of Samurais appreciated this design.
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.
Oval-shaped Tsuba that has Kozuka and Kougai holes. Golden coloring is applied to the outline of the Tsuba, Kozuka hole, Kougai hole, and clouds. It seems dragons’ bodies were also initially colored with the same color. This Tsuba has the signature of Ichiryu Tomoyoshi (一柳友善), whose name lasted 6th generations from the Edo period to Taisho period. Tomoyoshi was a famous metal worker in Mito domain (today’s Ibaraki prefecture). The most famous one is 4th generation.
Saya： Saya is the scabbard for the Japanese sword.
Raden technique is applied on this Saya. It is a kind of decorative technique that is often used for traditional craftworks. It uses the pearl part of seashells and put it into the engraved surface of lacquer or wood. Thanks to its iridescent luster, it gives a luxurious look to works.
Authentication Paper：NBTHK TOKUBETSU Hozon Certificate for the blade (No. 1009897)
