Antique Japanese Sword Katana Signed by Shinano Kami Nobuyoshi with NBTHK Hozon Certificate
【Description】
This blade was signed by Shinano Kami Minamoto Nobuyoshi (信濃守源信吉), who was active during the early Edo period (1644-1673) in Yamashiro province (Today’s Kyoto prefecture). Shinano Kami is an honorable official title given by the imperial court for his excellent craftsmanship. The signature also says that this blade was made from western carbon steel called Nanban Tetsu (南蛮鉄). Foreign carbon steel was very expensive back then and either swordsmith or the person who ordered it wanted to be pround of the social status by inscribing this fact.
Shinano Kami Nobuyoshi was allowed to inscribe a chrysanthemum emblem, which is the symbol of the Japanese emperor. His sword-forging technique was so great that the emperor licensed him to use this emblem, which was quite honorable for any swordsmiths. His son, Echizen no Kami Rai Minamoto Nobuyoshi, was also allowed to inscribe a chrysanthemum emblem.
The generations of Nobuyoshi belonged to Kyoto Mishina school. Mishina school was created by the first-gen Mutsu no Kami Omichi (陸奥守大道), also known as Kanemichi. It is said that initially, Kanemichi was from Mino province, exclusively forging blades for Shingen Takeda, a famous feudal lord. Later on, he moved to Kyoto by bringing his four sons and founded his school in Kyoto. Four sons were Iga no Kami Kinmichi(伊賀守金道)、Izumi no Kami Rai Kinmichi(和泉守来金道), Tanba no Kami Yoshimichi(丹波守吉道) and Echu no kami Masatoshi(越中守正俊). His sons and Shinano Kami Nobuyoshi were known as Kyoto Gokaji(京都五鍛冶), prestigious swordsmiths forging in Kyoto in the early Edo period. Mishina school was prosperous throughout the Edo period and spread to other parts of Japan, such as Osaka. The superb craftsmanship of the Mishina school was passed down for generations.
This blade is appraised as a Hozon Touken (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, well preserved and high quality with artistic value.
*Please keep in mind that there are a couple of minor Kitae kizu on this blade If you like to know more details, please feel free to contact us.
【Blade】
Cutting Edge Length (Nagasa): 69.6 cm ( 27.4 inches)
Curvature (Sori): 1.7 cm (0.67 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).
Fuchi-Kashira: A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
This Fuchi Kashira seems to be made from brass. About the design, you would find a Kawasemi (翡翠, kingfisher). The figure of an adorable kingfisher resting its wings on a branch of a plant growing near the water is engraved. This Fuchi Kashira has an elegant depiction of a natural landscape.
Kingfishers are migratory birds that come to Japan from spring to summer and leave Japan in the fall to migrate to their wintering grounds. This bird is also called the jewel of the forest due to its beauty. In addition, because it does not miss its target prey, it is considered an auspicious bird for achieving goals and praying for victory.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Seeing from the gaps of the Tsukamaki thread, we estimate the motif of this Menuki is the Hana Guruma (花車). We could find cherry blossoms, chrysanthemums, peonies, and other flowers. The Hana Guruma is the Gosho Guruma (御所車) decorated with various flowers. The Gosho Guruma is a commonly used term for the Gissya (牛車, oxcart). The Hana Guruma has the role of inviting the gods, bringing them closer, and the wish to ask for much happiness. Although most of the coloring has already faded due to aging, it seems golden paint was initially applied to this Menuki. We hope you enjoy the changes that have taken place over the years.
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.
This Yotsu-Mokkou-shaped brass Tsuba has Kozuka and Kougai holes. We estimate the motif of this Tsuba’s symmetrical design is leaves of the Kiri (桐, paulownia). Usually, this plant motif has been depicted with its flowers. The number of blooming flowers at each inflorescence means the ranks of this design. 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 holy plant. While it is unclear whether these auspicious meanings inspired the design of this Tsuba, it is an elegant piece of work.
Saya: Saya is the scabbard for the Japanese sword.
Authentication Paper: NBTHK Hozon Certificate for the blade (No.3032442)
