Antique Japanese Sword Katana Signed by Yasuuji with NBTHK Hozon Certificate
This blade was signed by Sashu Jyu Yasuuji (佐州住康氏), who was active during the early Edo Period (1684-1688). Sashu is also known as Sado island, which lies off the coast of Niigata Prefecture. Yasuuji was originally from Mino province (Today’s Gifu prefecture).
The MINO swordsmiths style, also known as MINO-DEN, basically has the TOGARI(Pointed shapes protruding from the Hamon )in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868).
MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area.
Mino is located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had a reputation for their practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. The tradition of excellent sword forging skills had been passed to the Edo period. And during the Edo period, many swordsmiths in Mino province moved to other part of Japan, looking for better job opportunities. Yasuuji is a good example.
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 black rust on this blade. If you like to see the detailed condition, please feel free to contact us.
Cutting Edge Length (Nagasa): 69.0 cm ( 27.1 inches)
Curvature (Sori): 0.9 cm (0.35 inches)
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process.
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 is decorated with lots of Botan (牡丹, peony) flower patterns. While some colorings have already faded due to aging, it seems golden paint was initially applied to these flowers. Peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a kind of good-omen motif; people regarded it as a rich harvest sign. As mentioned above, a peony is called the Botan in Japanese. When we write this flower’s name in Japanese, its second letter means mountain hermit medicine to give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Seeing from the gaps of the Tsukamaki thread, you would find an animal-designed Menuki is attached to each side of the handle. These two have different fur patterns, and the one with the striped pattern is probably a tiger. And the other animal with spotted fur is the Karajishi (唐獅子). The Shishi (獅子) means a lion in Japanese, and the Karajishi is a lion brought from the continent to Japan in the Toh period (唐, Tang dynasty, 618-907). The Karajishi typically has curly hair for its head, neck, body, and tail. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and the Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Karajishi originates from the Komainu (狛犬, stone guardian dogs that exorcize evil spirits).
Now, when we look at the entire handle, we realize the design of this Menuki and the Fuchi Kashira we mentioned earlier make a classical theme called the Botan-ni Karajishi (牡丹に唐獅子), which is a combination of peonies and Karajishis. There is a Houwa (法話, Buddhist monks tell the story of Buddhism in an easy-to-understand manner) that treats a Karajishi and this flower. The lion is called the king of the beasts. However, even this invincible animal has only one fear: a bug in the lion’s body. This pest grows in the lion’s hair, eventually breaking the skin and biting the flesh. Nevertheless, it dies if it is exposed to be the night dew of a peony. Therefore, the lion rests under peony flowers at night, looking for a haven. This story might have inspired the selecting of sword mountings of this Koshirae.
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 oval-shaped Tsuba has a symmetrical design. Its Mimi (耳, edge of a Tsuba) is framed with a thin metal plate. This decorative process is called the Fukurin (覆輪), and one of its purposes is to add beauty to works. In addition, it has practicality, such as preventing the wear of the edge part. Also, it prevents wear and tear on the Kimono if the edge damages it by touching the cloth. This Tsuba is composed of a smooth iron plate, except for the openwork of straight line patterns, and there are some rust spots here and there due to aging, giving it a tasteful feel.
Saya: Saya is the scabbard for the Japanese sword.
Authentication Paper: NBTHK Hozon Certificate for the blade (No.3014654)
