Antique Japanese Sword Katana attributed to the first-gen Kunisada with NBTHK Hozon Certificate
【Description】
This blade is attributed to the first-gen Izumi no Kami Kunisada. Kunisada, also known as Inoue Yoshihiro. He was born in the 17th year of Tensho era(1589) in the southern part of Miyazaki prefecture(Kyushu island). Later on, he moved to Kyoto and became an apprentice of Horikawa Kunihiro, one of the most famous swordsmiths in the early Edo period(early 17th century). He also learned the sword-forging technique from a senior apprentice, Echigo no Kami Kunitomo. Kunisada moved to Osaka in 1620 after his master, Kunihiro, was deceased. He became an independent swordsmith in Osaka city.
Kunisada was trusted by the third-gen head of Obi domain(Miyazaki prefecture), Ito Sukehisa, and Kunisada was able to receive the title of Izuminoakami in 1623 because of Sukehisa’s support.
He is known as one of the most influential swordsmiths to make Osaka a famous place for sword-forging in the early Edo period. Osaka was the center of business back then. Many renowned swordsmiths moved to Osaka to meet the demand from high-class Samurais.
His son Inoue Shinkai is also a well-respected swordsmith and trained many apprentices who later became famous swordsmiths. Inoue Shinkai also signed Kunisada at the beginning of his career. To distinguish Kunisada and his son, the first-gen is called Oya Kunisada(Father Kunisada). The second-gen is called Shinkai Kunisada. He died at the age of 63 in 1652.
His blades are known as Owazamono, extremely sharp blades. He is one of the most famous swordsmiths in Osaka during the early Edo period. It is said that Horibe Yasube(堀部保兵衛), one of famous 47 Ronin used one of Kunisada’s work.
The blades forged by the first-gen Izumi no Kami Kunisada are categorized as Osaka Shinto. Shinto is Japanese Sword terminology that refers to the swords forged during 1596-1781. The blades made in the Osaka area during this period are called Osaka Shinto. There are many famous swordsmiths in this Osaka Shinto era. After Hideyoshi Toyotomi built Osaka castle, Osaka city flourished as a castle town and became the business center. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Ikanshi Tadatsuna(Awataguchi Omi no Kami Tadatsuna), Inoue Shinkai, and Tsuda Sukehiro are the most famous among many swordsmiths.
One of the most notable characteristics of Osaka Shinto is its beauty in Jigane. Jigane is a visible steel surface pattern created by folding and hammering during the forging process), which made it possible by the location of Osaka. Osaka had close access to the Tamahagane(special carbon steel to make Japanese swords) production sites. The swordsmiths residing in Osaka were able to get high-quality carbon steel from these sites.
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.
【Blade】
Cutting Edge Length (Nagasa): 69.6 cm (27.4 inches)
Curvature (Sori): 1.2 cm (0.47 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.
Based on its metal color, we think this Fuchi Kashira is made from brass. And about the design, it seems to be influenced by continental culture. On the Kashira part, you would find the figures of two men. One is a man with a long beard wearing a helmet, and the other is a man dressed like a civil servant bringing a box. It is unclear whether they are famous figures in history or characters in a story, but their clothes are continental. And they seem to be having a military council or something.
If you focus on the Fuchi part, you will see a long spear and a Gunpai (軍配, Sumo referee’s fan today) are designed. The Gunbai is a tool that is related to the Samurai culture. After the Ohnin-Bunmei era (応仁・文明年間, 1467-1487), military commanders used Gunbai-Uchiwa (軍配団扇) to encourage their subordinates by using it. Also, it was used for ordering the arrangement of an army: For example, the placement of troops, the date and time of the advance, and retreat.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Aoi (葵) leaves are designed on this Menuki. It is a plant in which each stem branches and has characteristic heart-shaped leaves. Although some colorings have faded due to aging, it seems golden paint was initially applied to these Menukis. This plant pattern is famous for the family crest of the Tokugawa family, who governed the Edo Shogunate. It has also been used for the crest of the Kamo shrine in Kyoto prefecture. As mentioned above, the famous Shogunate family, the Tokugawa family, had their family crest with three leaves of Aoi due to their relationship with the Kamo shrine. Since its leaves have a habit of always facing the sun, and the word “Aoi” is taken as action “Aogu (仰ぐ, looking up)” for the sun, people thought the Aoi pattern would bring good fortune.
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 Tsuba has a symmetrical design. By using openwork boldly with bold curved lines instead of gold or silver decoration, its design is simple but never plain. We would say this Tsuba looks elegant thanks to these engravings.
Saya: Saya is the scabbard for the Japanese sword.
Authentication Paper: NBTHK Hozon Certificate for the blade (No.3020047)
NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan. They authenticated the blade on Feb 25th in the 31st year of Heisei (2019). They appraised it as Hozon Touken, the blade worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
