Antique Japanese Sword Katana Signed by Bishu Osafune Sukesada with Tokubetsu Hozon Certificate
This blade was signed by Bishu Osafune Sukesada (備州長船祐定) in August, the 12th year of the Eisho era (1515: Late Muromachi period). Bishu（備州）is a larger area in today’s Okayama＆Hiroshima prefecture. Bishu consists of Bizen(備前), Bitchu（備中） and Bingo (備後). Osafune is the school’s name located in Bizen province. 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 high-class Samurai and he might have carried it in a battlefield.
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 Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths to forge 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 after the late Heian era(Late 12th century ).
This blade is relatively short but has no trace of getting shortened (Suriage) in the past. Considering these facts, we believe this blade was primarily made for one-hand combat. The user could hold this sword with one hand, a popular way to fight during the late Muromachi period.
This blade is appraised as a Tokubetsu Hozon Token(特別保存刀剣) 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.
*Please keep in mind that there are a couple of minor Kitae Kizu on this blade. If you like to know the detailed condition, please feel free to contact us.
Cutting Edge Length(Nagasa)： 66.0 cm( 26.0 inches)
Curvature(Sori)： 2.27 cm( 0.89 inches)

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.
Peonies are designed on this Fuchi Kashira, and golden paint is applied to these flowers. This coloring adds decorativeness to this work. Each flower is engraved carefully, and its elegant figure is depicted gorgeouslly. 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. Peony is called “Botan” in Japanese. When we write this flower’s name in Japanese, 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.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Each Menuki is an element of the Takaradukushi (宝尽くし) pattern. It is the combination of several treasures. Some people believed these treasures would bring good fortune. The upper Menuki, this motif is probably the Kinnou (金嚢); it is a bag to store treasures. A theory says it has been regarded as a money charm. The lower side Menuki, you would find an Uchide-no-Koduchi (打ち出の小槌, mallet of good luck) and coins. It is believed that this mallet would fulfill one’s wish, or defeat one’s enemy. The former owner of this Katana might have chosen such auspicious designs wishing to grasp luck with money.
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.
Aorigata (障泥形) Tsuba made from iron. This Tsuba’s theme is the Karakusa (唐草, arabesque) design, and Karakusas are inlaid with gold. It is a pattern in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (蔓) in Japanese, and it has another pronunciation; “Man.” There is a word 万 (it is also read Man), which means thousand. In the Karakusa pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read as “Tai.” Due to its pronunciation, the term “代 (Tai)” is associated. From this word-association game, an idiom 万代 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.
This Tsuba was appraised as a Hozon Tosogu on Dec 22nd in the 21st year of the Heisei era (2010). According to the certificate, this Tsuba has the Koudai Higo (後代肥後)-style.
Saya： Saya is the scabbard for the Japanese sword.
The Sagari-Fuji (下がり藤: Wisterias) pattern is designed on this Saya. As wisterias have strong fertility and grow being entwined with other trees, people regarded this flower as a symbol of longevity and prosperity for future generations. Also, its Japanese name Fuji (藤) is likened to another word Fushi, which is written as “不死,” which means immortality. According to a theory, that is why the Fujiwara (藤原) family, who reached the height of glory in the Heian period (794-1185), used this motif for their family name and family crest.
Authentication Paper：NBTHK TOKUBETSU Hozon Certificate for the blade (No. 1014687)
NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan. They authenticated the blade on Feb 25th in the 3rd year of Reiwa (2021). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society.
