Antique Japanese Sword Katana Signed by Kashu Ietsugu with NBTHK Hozon Certificate
【Description】
Summary
This blade is attributed to Kashu Ietsugu (加州家次), a swordsmith active during the late Muromachi period (early 16th century). The term Kashu (加州) refers to the province now known as Ishikawa Prefecture (石川県), historically called Kaga Province (加賀国).
Ietsugu lived and worked in this province, crafting swords as his livelihood. During his time, Kaga Province was under the rule of the Maeda clan. The Maeda family originally served as retainers of the Oda clan , which governed Owari Province (尾張国, modern-day Nagoya in Aichi Prefecture). The Maeda clan’s rise to power began with its first leader, Toshiie Maeda, who advanced through the ranks of samurai society to become the feudal lord of Kaga Province.
Toshiie Maeda governed a domain famous for its vast rice production, known as Hyakuman Goku, symbolizing wealth sufficient to feed one million people. Under Toshiie’s leadership, the Maeda clan became one of the most influential samurai families in history, maintaining strong ties with both Oda Nobunaga (織田信長) and Hideyoshi Toyotomi (豊臣秀吉).
Tachi Koshirae
This blade is stored in 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.
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 few noticeable Kitae Kizu on this blade. If you like to see the detailed condition, please feel free to contact us.
【Blade】
Cutting Edge Length (Nagasa): 68.6 cm ( 27.0 inches)
Curvature (Sori): 2.0 cm (0.78 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.
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. In addition, the Fuchi Kanamono (縁金物) is also a metal fitting attached to the handle, but on the opposite side of Kabutogane. These parts correspond to the Fuchi Kashira (縁頭) in Katana Koshiraes (刀拵).
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The Menuki features a dragon, a powerful and revered symbol in Japanese culture. In Japan, dragons are often associated with water and rainfall, signifying their role as guardians of rivers, seas, and skies. They are seen as benevolent creatures that bring prosperity, good fortune, and protection. Additionally, the dragon is a symbol of strength, wisdom, and authority, embodying a mystical power that transcends human limitations. As a mythical creature deeply rooted in Japanese folklore and traditions, the dragon is often considered an auspicious emblem that wards off evil and ensures harmony.
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 the same motif, paulownia (桐, Kiri), as the Fuchi Kashira. Also, this Tsuba has a shape which is similar to a Yotsu-Mokkou (四ツ木瓜) shape, which is a circular design with indentations along the edges. It is also made of iron, which makes it strong and durable.
If you focus on the four corners, you will find a heart-mark hole at each corner. On this Tsuba, you could find eight heart marks in total on each side. This heart mark-shaped design is the Inome (猪の目, boar’s eyes) pattern. It has been used since ancient times. Some people believed the Inome pattern would bring good luck and protect people from evil spirits or fire.
Saya：Saya is the scabbard for the Japanese sword.
*Please keep in mind that there are a few traces of the restoration on this Saya.
We estimate the surface of this Saya is decorated with double-flowered plum (八重梅, Yae-Ume). The Yae-Ume tree, celebrated for its profusion of layered blossoms and graceful appearance, is cherished as an ornamental plant. Its deep connection to Japanese traditions stems from its symbolic representation of “longevity,” “vitality,” and its remarkable ability to bloom even in the harsh cold of late January. These qualities have established it as a quintessential emblem of celebration and good fortune, alongside pine and bamboo in the classic trio known as “Sho Chiku Bai” (松竹梅).
