Antique Japanese Sword Katana Signed by Bishu Osafune Sukesada with NBTHK Hozon Certificate
【Description】
This blade was signed by Bishu Osafune Sukesada (備州長船祐定) in the 10th year of the Eiroku era (1567: Late Muromachi period). Bishu, also known as Bizen, is the name of the province located in Today’s Okayama prefecture. Osafune is one of the most prosperous schools in this province during the Muromachi period. Sukesada is his maker’s name.
Those who forged swords in the Bizen province (Okayama prefecture) at the end of the Muromachi period (1492-1569 A.D) are called Matsu Bizen (Matsu means the end). Sukesada school was one of the most famous schools, and it flourished for generations among Osafune schools (The head branch). There were various styles forged by the generations of Sukesada during this period. Approximately 60 swordsmiths used Sukesada as his maker’s name in the Samurai history. In that sense, the swordsmith’s name “Sukesada” worked as a kind of brand that attracted many Samurai.
The swordsmiths in Bizen produced many swords during the Muromachi period as it was in the middle of the Sengoku period (Warring state period). The demand for weapons increased among strong feudal lords. It would be nice to have a piece forged in the warring state period when there was so much rivalry between warlords. It was possible that this blade was ordered by a Samurai and he might have carried it in a battlefield.
This History of Bizen Osafune School
It is said that Osafune school was founded by Mitsutada (光忠), who was active during the mid-Kamakura period. Bizen Osafune school was the biggest one of all other schools in Bizen province, and they received many orders from feudal lords or renowned Samurai. They were called Osafunemono and were beloved by Samurai warriors.
Among the swordsmiths who belonged to this school, Nagamitsu, Sanenaga, and Kagemitsu are known as Osafune Sansaku, the three renowned Osafune swordsmiths. There are also four other prominent swordsmiths who were from Bizen Osafune school. They are called Osafune Shiten-no, the four masters of Osafune school. Their names are Nagamitsu, Kanemitsu, Nagayoshi, and Motoshige.
BIZEN is located near the Chugoku Mountains, where iron sands, one of the essential materials for making Japanese swords, were abundant. Furthermore, BIZEN swordsmiths had close access to the Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths forging high-quality refined blades. We presume BIZEN was quite active in sword-forging from ancient times. It is said that BIZEN DEN was created by groups of swordsmiths there during the late Heian era (Late 12th century). These ancient swordsmiths in Bizen province are called Ko-Bizen (Old Bizen) swordsmiths. By inheriting the sword forging techniques from Ko-Bizen swordsmiths, the Bizen Osafune school flourished from the mid-Kamakura period.
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 visible Kitae Kizu on this blade. If you like to see the detailed condition, please feel free to contact us.
【Blade】
Cutting Edge Length (Nagasa): 69.2 cm ( 27.2 inches)
Curvature (Sori): 1.1 cm (0.43 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.
On this Fuchi Kashira, you would find several drop-shaped objects are carved. We estimate these are the Houju (宝珠, ball fulfills desires), which is one of the elements of Takaradukushi (宝尽くし) theme. It is a combination of treasures. For example, the Kakure-Mino (隠れ蓑, straw raincoat) and the Kakure-Gasa (隠れ笠, hat that hides face) would protect us from danger or illness. The Chouji (丁子, precious medicine, fragrance, dye) is a plant, and it represents happy marriage, good health, and longevity. The Uchide-no-Koduchi (打ち出の小槌, mallet of good luck) would fulfill one’s wish, or defeat one’s enemy. It is well-known that the Daikokuten (大黒天, god of wealth), who is a member of the Shichifukujin (七福神, the Seven Gods of Good Fortune), brings this mallet. The Makimono (巻物, scroll) is a book that gives us much information; therefore, this motif symbolizes knowledge and wisdom. The Gunbai (軍配, Sumo referee’s fan today) would settle the battle. The Fundou (分銅, weight) is the symbol of wealth. The Takaradukushi Zu is a design that combines these various types of treasures, and a Houju is included in this theme.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
While we cannot see the entire shape of each Menuki, we think these are the motifs that relate to religious scenes. For example, please focus on the upper Menuki. We could find a bell with a string. According to the Wakun-no Shiori (和訓栞, Japanese dictionary in the late Edo period) written in 1777 during the Edo period, a bell was given its name because of its “Suzushii (すずしい, cool)” sound. And it was said that if you struck a bell, it would have magical power to exorcise evil spirits. Bells have been used as a ritual tool for a long time.
As mentioned above, bells have been used to ward off beasts and evil spirits, and at shrines, they are also used to call out to the gods. It is also said that it has been involved in people’s lives since ancient times, as it is used to communicate with enemies and allies.
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.
An aggregate of small circles composes this Tsuba’s shape. There is a crest that has the same look with it. It is called Hoshi Mon (星紋, star) or Kuyou Mon (九曜紋). Each circle represents a star. Stars have been worshipped as a holy existence that controls fate. Since each star moves in a fixed orbit, people could know the position during hunting or voyages or know the agriculture season. That is, stars have a deep relationship with people’s daily life. With time, stars came to be treated as a design, and some people arranged it for their family crests.
There are various types of Hoshi Mon, such as three stars, seven stars, and nine stars as this work. Three stars design is called Mitsu-Boshi (三つ星) in Japanese, and it means Kachi-Boshi (勝ち星, winning star). For warriors who lived on the battlefields, it is understandable that many Samurais loved such an auspicious motif. For example, Date Masamune (1567-1636), one of the famous warlords, used Kuyou Mon for his family crest.
Saya: Saya is the scabbard for the Japanese sword.
