Antique Japanese Sword Katana Signed by Bishu Osafune Sukesada with NBTHK Tokubetsu Kicho Certificate
【Description】
This blade was signed by Bishu Osafune Sukesada (備州長船祐定) during the 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.
*Please keep in mind that there are a couple of visible Kitae Kizu on this blade. If you like to know more detailed condition of the blade, please feel free to contact us.
【 Blade】
Cutting Edge Length(Nagasa)： 75.1 cm ( 29.5 inches)
Curvature(Sori)：1.51 cm (0.59 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
Kissaki: Kissaki is the tip of the Japanese sword.
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 motifs of both sword mountings, this Fuchi Kashira and the Menuki we will mention later, are related to birds. On the Kashira part, you could find the figure of a bird standing on a rock in the waves. A scene of waves crashing into each other is depicted throughout this piece. The bird’s eyes, legs, and water splashes are decorated with gold coloring here and there.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The same as the Fuchi Kashira, each Menuki’s motif is a bird. The design depicts a bird with a large cock’s crest spreading its wings in flight. While we are unsure about the kind of these birds, we estimate that a bird familiar to Japanese people was modeled here.
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.
We think this Tsuba is composed of two classical theme: Botan Karakusa (牡丹唐草), and Karajishi Botan (唐獅子牡丹). The former is a combination of Botan (牡丹, peony) and Karakusa (唐草, arabesque), and the latter is a combination of Karajishi (唐獅子) and peonies. On the front of this Tsuba, we could see the figures of animal-like figures, and the Karakusa pattern is engraved around them. On the other hand, the backside of this Tsuba is decorated with a large flower pattern.
Firstly, we focus on the Botan Karakusa pattern. Peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a 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 Kanji characters, its second letter means mountain hermit medicine that would give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity.
The Karakusa pattern is a design in which vine stems and leaves are twined to make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Among the Karakusa patterns, the Botan Karakusa pattern has been favored as a representative design of Karakusa patterns since the Muromachi period.
About the Karajishi, 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 Kara-Jishi originates from the Komainu (狛犬, stone guardian dogs that exorcize evil spirits). There is a Houwa (法話, Buddhist monks tell the story of Buddhism in an easy-to-understand manner) that treats the 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 and eventually breaks the skin and bites the flesh. Nevertheless, it dies if it is exposed to the night dew of a peony. Therefore, the lion rests under peony flowers at night, looking for a haven. This Tsuba’s design might have been quoted from this story.
Saya： Saya is the scabbard for the Japanese sword.
