Antique Japanese Sword Tanto Signed by Tsuguyoshi with NBTHK JUYO TOKEN Certificate
【Description】
Summary
This blade was signed by Bitchu no Kuni ju Tsuguyoshi (備中国住次吉), dated to the 5th year of the Enbun era (1360, mid-Nanbokucho period), according to its NBTHK appraisal. Bitchu corresponds to today’s Okayama Prefecture. Tsuguyoshi was one of the most prominent swordsmiths of the Aoe school during the mid-Nanbokucho period.
Aoe school was founded by Yasutsugu (安次) during the late Heian period (Early 12th century), and it was located in today’s Kurashiki town, Okayama prefecture. In Bitchu province, there were two prestigious schools during that time. One is Aoe school, and the other is Seno school, established by Noritaka (則高). Aoe school was prosperous from the late Heian to the late Nanbokucho period.
Aoe school is divided into three categories in Japanese sword terminology depending on the period. When the blade is from the late Heian-mid Kamakura period, it is called *Ko-Aoe (Old Mihara). It is called Chu Mihara(Middle Aoe) for those forged in the mid Kamakura-early Nanbokucho period. Finally, Sue-Aoe (Late Aoe) is used for the late Nanbokucho period or later. Based on the inscription on the tang, we believe it is categorized as Chu Aoe or Sue Aoe.

One of the most famous figures in Aoe school is Moritsugu, who trained Sadatsugu, Tsuguie, and Tsunetsugu. These three swordsmiths were famous for Gobankaji (御番鍛冶). Gobankaji is a unique system created by the retired emperor Go-Toba (後鳥羽上皇), who was enthusiastic about the Japanese sword-forging. He summoned twelve of the finest swordsmiths nationwide, and one swordsmith forged a blade for the emperor each month. Tsuguyoshi was the son of Tusuguie, who must have mastered superb craftsmanship.
Bitchu 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 Takahashi River, where they could find water and charcoal. This geological location contributed to the swordsmiths forging high-quality refined blades.
When Aoe school flourished in the Nanbokucho period, Japan was tumultuous because the imperial court was split into two sides(south and north). There were many conflicts, and many Samurai were deployed. The Aoe school must have dedicated itself to forging high-quality blades for those Samurai who fought in battles. It is said that they were land owners and Samurai as well. They served the southern imperial court, which ended up losing the battle against the northern imperial court. After the southern side was lost, the school’s property was ended. However, the descendants of a member of Aoe school established another school called Mizuta school in the Muromachi period, and lasted during the Edo period.
What is Tanto?
Japanese swords under the blade length of 30cm (11.6 inches) are generally called TANTO, and sometimes TSUBA(鍔; Hand-Guard) is not attached to the TANTO. It was easy to carry and convenient for close combats. It was initially used as a supplemental weapon for Samurai on horseback, who used a pole weapon or long sword in the Kamaura-Muromachi period. Samurai aimed at an unprotected area of his enemy’s armor with Tanto while having to fight with close distance.
TANTO was named accordingly, depending on how you carry it, such as HUTOKORO-GATANA (懐刀; Stomach-Sword) or KOSHI-GATANA(腰刀; Waist-Sword) or elsewise. TANTO was also a gift for a bride from her family in a traditional Japanese wedding, as it is believed that TANTO would be divine protection from evil power.
Appraisal
This blade is appraised as a JUYO TOKEN (重要刀剣) 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, exceptionally well preserved and of high quality with artistic value. JUYO is one rank higher than Tokubetsu Hozon. To be eligible for a Juyo Token, it needs to be appraised as a Tokubetsu Hozon Token first. It is extremely rare for an antique Japanese sword to be appraised as JUYO TOKEN, and it is highly desirable among Japanese sword collectors.
*Please keep in mind that there is a couple of Kitae Kizu on this blade. If you like to know the detailed condition, please feel free to contact us.
【Blade】
Cutting Edge Length (Nagasa): 27.1 cm (10.6 inches)
Curvature (Sori): 0.2 cm (0.07 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.

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.
We believe the theme of this Fuchi Kashira is Seashells (貝尽くし, Kai Dukushi).
This pattern is a combination of different types of seashells. It is often designed with a seaside scene or wave pattern. You would feel the refreshing atmosphere of summer. Bivalves, especially clam, its shells cannot be combined with any other clam’s frame; therefore, its pattern represents happy marriage.
Seashell is called Kai (貝) in Japanese. Because of its pronunciation, the seashell has another meaning. There is a word Yarigai (やりがい, worthwhile). As a part of this word has the same accent as Kai (貝 is read Gai in some cases), Japanese people found this meaning. Also, since seashells are hard and combine only with their pair, people thought it represented a robust defense. Due to these meanings that inspire warriors who go to the battlefields, Samurais might have loved this motif.

Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The theme of the Menuki is Karajishi (唐獅子, lion).
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, as seen on this work. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Karajishi is the origin of Komainu (狛犬, stone guardian dogs that exorcize evil spirits). It shows this animal motif has been familiar to Japanese people since ancient times.

Habaki:Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.

Kozuka: Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).
The theme of this Kozuka seems to be Ume (梅, Japanese apricot blossom). Japanese apricot blossoms begin to bloom in winter that snow still covers its tree so that people thought this flower tells the arrival of spring. Same as cherry blossom, it has been appreciated for a long time in Japan. People enjoy its adorable petal shape and scent, gracefully branched tree, and compose many poems. As it comes out in the cold season, it symbolizes the power of perseverance and vitality.

Saya: Saya is the scabbard for the Japanese sword
This saya features a decorative lacquer technique known as Fuemaki-nuri (笛巻塗). The name literally means “flute-wrap lacquer” and refers to a method in which thin cords or strings are wrapped around the scabbard before being coated with multiple layers of lacquer. Once dried and polished, the surface reveals a textured, ridged pattern reminiscent of the wrapping on a traditional Japanese flute (fue, 笛).

Lacquer box (Tanto box): A traditional lacquered container designed for the storage or ceremonial presentation of distinguished tanto
The theme of this lacquer box is the Aoi-Karakusa (葵唐草). Aoi (Asarum caulescens, 葵) is a plant pattern in which each stem branches and has characteristic heart-shaped leaves. As its leaves have a habit of always facing the sun, and the word “Aoi” is taken as “Aogu (仰ぐ, looking up)” for the sun, people thought the Aoi pattern would bring good fortune.
Karakusa (Arabesque) 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 ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read “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.

Authentication Paper: NBTHK JUYO TOKEN Certificate for the blade (No. 7728)
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 October 18th in the 59th year of Showa (1984). They appraised it as JUYO TOKEN, the blade exceptionally worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
