Antique Japanese Sword Katana Signed by Yokoyama Sukenari Hozon Certificate 

【Description】

Summary

 This blade was signed by Bingo Fukuyama Jyu Yokoyama Sukenari (備後福山住横山祐成) during the Tenpo era (1830-1844): the late Edo 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). And, bingo is the place Sukenari lived when he forged this blade. Fukuyama is the name of the village in this area. Yokoyama is the school to which he belonged. The headquarter of this school is Osafune school.

Yokoyama school is one of the most renowned schools in Bizen province during the late Edo period. Yokoyama Sukenari originally lived in this area, belonging to this school to improve his craftsmanship. He was invited by Abe clan to move to Fukushima village in his career. There was a record of Sukenari doing a Daimei for Sukenaga, one of the most prominent figures in this Yokoyama school.  Daimei is a regular act where an apprentice or a child of the swordsmith signed his master’s name with his master’s permission, being involved in a sword-forging. We believe Sukenari worked for Sukenaga, and his level of craftsmanship must have been closed to his master.

About Sukesada school

Sukenari’s ancestors dated back to Sukesada school, one of the most famous schools, and flourished for generations among Osafune schools (The head branch). There were various styles forged by the generations of Sukesada during the Muromachi-Edo period. There were about 60 swordsmiths who used Sukesada as his maker’s name in Samurai history.

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. However, The sword-forging tradition of Bizen province almost disappeared because of the disastrous flood of the Yoshii River (1591), which was close to Osafune school. Even after everything was destroyed, there were few remaining swordsmiths. One of them was a group of swordsmiths who signed Sukesada. The main member of the school was Yokoyama Fujishiro Sukesada, the fourth head of Sukesada School. And one of his children was Shichibei no Jyo Sukesada (七兵衛尉祐定). They became one of the pioneers that revitalized the sword-forging business in Bizen province. Sukenari was a descendant of this Sukesada.

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.

 

Tachi Koshirae 

 This blade is stored in Tachi(太刀) Koshirae. Tachi was mainly used by an armored Samurai with one hand on horseback from the Heian period (794-1185 A.D.) until the early Muromachi period. TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground. Because of its gorgeous looking, having a Tachi-style sword mounting became a social status among Samurai. 

 

  It is appraised as a 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, well preserved and high quality with artistic value.

 

*Please keep in mind that there are a couple of small Kitae Kizu on this blade. If you like to know the detailed condition, please feel free to contact us.

Kissaki: Kissaki is the tip of the Japanese sword.

 

NakagoNakago 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-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.

 This Fuchi Kashira and the Kojiri (鐺, the metal fitting that protects the tip of a scabbard) have the same style. It seems these metal fittings were made from copper, and golden paint was applied to their surface. While some paints have already faded due to aging, this coloring plays a role in adding decorativeness to this handle, which looks gorgeous.


Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 A dragon is the motif of this Menuki. The same as the Fuchi Kashira, golden paint was applied to each dragon. Initially, dragons were imaginary creatures found in ancient foreign traditions and myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, the belly is the Mizuchi (蛟, a mythical animal in Japan that looks like a snake and has a horn and four legs), scales are fish, claws are falcons, palms are tigers and ears are cows. A dragon was thought to reign at the top of all animals because of its odd appearance. Based on our experiences, there are lots of dragon-designed sword mountings. It shows that many Samurai warriors favored this dignified beast motif.

 Among dragon-designed Menukis, we often find dragons who bring a ball-shaped object in their hands based on our experience. This item is the Nyoi Houju (如意宝珠, Cintāmaṇi), a fantasy jewel that fulfills any desire and gives out treasure, clothes, food, and drinks. Moreover, it heals illness and suffering, removes evils, purifies muddy water, and prevents disasters. It is said this magical item is taken from the brain of the dragon king. In this way, dragons are cherished for their auspiciousness.

   
Tsuba and HabakiTsuba 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 Tsuba has a Yotsu-Mokkou (四ツ木瓜) shape. Its Mimi (耳, edge) is finished thicker than the other parts. The entire surface is colored with golden paint, and several plant motifs are designed on this work: Kiri (桐, paulownia), Sakura (桜, cherry blossom), and Karakusa (唐草, arabesque). These plants have been treated as auspicious motifs.

 The Kiri pattern generally comprises three standing straight inflorescences and three leaves. The number of blooming flowers at each inflorescence means the ranks of this design. The Gosan-no-Kiri (五三の桐) pattern is a popular design that the paulownia motif is used. According to tradition, the Houou (鳳凰, Fenghuang) rests its wings at the paulownia tree; therefore, it has come to be regarded as a holy plant. Cherry blossom is one of the seasonal things of spring, and Japanese people have appreciated this plant for a long time. A theory says that the god of grain exists in cherry blossoms. Therefore, this flower pattern has been treated as the symbol of a plentiful harvest. The Karakusa pattern is a design in which vine stems and leaves are twined and make curves. Since ivy has a strong vitality and grows without interruption, people regarded this design as a symbol of prosperity and longevity.

 In addition, you would find the combination of nine circles mark with plant designs. It is called the Hoshi (星, star) pattern or the Kuyou (九曜) pattern. As its name implies, 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 suitable position during hunting, voyages, or the agricultural season by seeing stars. 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. The Kuyou pattern is one of them. There are various types of Hoshi Mon, such as three stars, seven stars, and nine stars. Three stars design is called the Mitsu-Boshi (三つ星) in Japanese, and it means the Kachi-Boshi (勝ち星, winning star). For warriors who lived on the battlefields, it is understandable that many Samurai warriors favored such an auspicious motif.

Saya Saya is the scabbard for the Japanese sword.
