Antique Japanese Sword Katana Signed by Osafune Sukesada with Hozon Certificate
This blade was signed by Bishu Osafune Sukesada (備州長船祐定). 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.
It 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, especially well preserved and high quality with artistic value.
Cutting Edge Length (Nagasa): 61.8 cm (24.3 inches)
Curvature (Sori): 2.6 cm (1.02 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.
It seems the surface of this Fuchi Kashira was initially decorated with the Nanako-Ji (魚子地) technique. This process makes a uniform minimal protrusions pattern by hitting the Nanako-Ji Tagane (魚子地鏨, a chisel for this technique) on a metal surface. This decorative technique is often seen on sword mountings.
You would find various types of plants are designed on this Fuchi Kashira. The Aki-no Nanakusa (秋の七草, the seven herbs of fall) and chrysanthemums are often seen in autumn plant designs. Although some colorings have already faded due to aging, we could see golden paintings applied to these motifs. And chrysanthemum pattern is the common design of sword mountings of this Koshirae.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The design features chrysanthemums floating on the surface of the water. We would say it is a kind of Kikusui Mon (菊水紋). It depicts chrysanthemum flowers floating in running water. Since a long time ago, the Kikusui Mon has been known as a design that represents longevity based on a foreign legend. It says we could extend our lifespan by drinking water flowing from the chrysanthemum colony. Therefore, people treated this design as a kind of good luck motif. It is said this pattern started to be used in the Kamakura period (1185-1333), and some families, including Samurai families, used this motif for their family crests. In this work, its shape does not seem to have been specifically designed as a family crest. However, the meaning implied in the design might be shared.
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 decorative appearance. Many chrysanthemum flowers are designed to fill the screen. Each petal and even the veins of the leaves are finely carved; this Tsuba shows the careful work of the metalworker. A long time ago, the chrysanthemum was used as a medicine for obtaining a long life on the continent, and it was brought to Japan with this thought in the Nara period (648-781). Chrysanthemum is one of the flowers which symbolizes fall, and people have appreciated it since ancient times. As its petals form radially, the chrysanthemum has been likened to the sun. That is why this flower pattern is treated as the symbol of perpetual youth and longevity or good health.
As with the other sword mountings mentioned above, chrysanthemum patterns are incorporated into metal parts of this Koshirae. We feel the taste of the former owner of this sword from here. We hope you will enjoy the Koshirae with the beauty of the blade.
Saya: Saya is the scabbard for the Japanese sword.
Authentication Paper: NBTHK Hozon Certificate for the blade (No. 3029345)
