Antique Japanese Sword Katana Unsigned Ko-Uda with NBTHK Tokubetsu Hozon Certificate 

【Description】

This blade is attributed to the work of Uda school by NBTHK, which authenticated this blade. While the certificate doesn’t mention when it was forged, NBTHK appraises it was made in the Kamakura-Nanbokucho period (Approx. 1299 – 1393). We made a phone call to NBTHK to confirm it.

Uda is a prestigious school that flourished during the Nanbokuchoto-mid Muromachi period(approx. 1334-1491). It was founded by Kunimitsu(国光) in the late Kamakura period. The school was located in Etchu province in Toyama prefecture today. Kunimitsu was originally from Yamato Uda Gun(大和宇多郡), located in Nara prefecture but moved to Etchu in the late Kamakura period(1299-1333) with his apprentices including Kunifusa(国房), and Kunimune(国宗).
Uda school was famous for producing practically designed blades, which were desirable during Nanbokucho- Muromachi period. Among other schools in the Hokuriku region(the northwestern part of Honshu), Uda school was the most prominent school.

When the Uda school flourished in the Nanbokucho period, Japan had a tumultuous time because the imperial court was split into two sides(south and north). There were so many conflicts, and many Samurai were deployed. The trend in battlefields was to use a surprisingly long sword. This trend continued until the early-mid Muromachi period. This blade doesn’t look long now, but we assume it used to be quite a long sword based on the tang’s shape, meaning it was shortened a few times in the past.

There are two categories in the work of Uda school. One is called Ko Uda(Old Uda), and the other is called Uda. Ko Uda swords were forged during the late Kamakura period to the Nanbokucho period. Uda blades were forged during the Muromachi period. This blade is categorized as a Ko-Uda blade.

This blade is appraised as Tokubetsu Hozon certificate issued by NBTHK. This authentication paper was only given to Japanese swords, especially worth preserving by Nihon Bijutsu Touken Hozon Kyokai(the Society for the Preservation of the Japan Art Sword). It has beautiful Suguha tempering line with vivid Jihada. It accompanies with gorgeous sword mountings.

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(Sabbard), Tsuka( Handle), Tsuba(Handguard).

 

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

 Ume (梅, Japanese apricot blossom) decorates this Fuchi Kashira. Furthermore, Matsuba-Mon (松葉文, pine needles pattern) is also designed. These plants are inlaid with silvery metal. Japanese apricot blossoms bloom in winter that snow covers its tree. So that people thought this flower tells the arrival of spring. Japanese people appreciate this flower for a long time. 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.

 About Matsuba-Mon, even if the pine needles fall, the roots of the two leaves are firmly connected and do not separate. Therefore, this plant motif has been treated as a lucky charm. Due to this idea, it also represents happy marriage. There was a famous Shogun who cherished this design. Tokugawa Tsunayoshi, the 5th Shogun of the Tokugawa Shogunate, used Matsuba-Mon as his Sadame-Mon (定め紋, Shogun or Daimyo set their own pattern).  

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

 As we could see its characteristic elongated body, it might be a dragon that is the motif of this Menuki. Initially, it is an imaginary creature found in ancient traditions or myths. Furthermore, it is 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, belly is Mizuchi (蛟, mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. Also, in Japan, there is a belief that worships dragon as a water god and is called Ryujin Shinkou (竜神信仰). Since rice cultivation has been flourished in this country, water is always an essential resource. So that the dragon motif has been familiar with Japanese people since a long time ago, we would like to guess that it might be a reason why this beast pattern is often found even in sword mountings.
   
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 is made from iron and has Kozuka and Kougai holes. Since it does not have metal inlay decoration or a complex engraving design, we hope you would enjoy the texture of the iron material itself. Also, Inome (猪の目, boar’s eye) pattern decorates its four corners. Inome pattern is used since ancient times, and it looks similar to the heart mark. Some people believed that this design works as an amulet to protect us from evil spirits or fire. Also, it is said it would bring good luck. This pattern is often found in traditional Japanese architectures such as shrines or temples and used Gegyo (懸魚, decoration under the roof, where the roof is jointed) or metal fittings for hiding timber joints.

Saya Saya is the scabbard for the Japanese sword.  

KougaiKougai is the equipment for Samurai to arrange or fix his hair style.

 The dragon wraps around the sword. It seems the motif of this Kougai might be the Kurikara Ken (倶利伽羅剣, the sword that Fudo Myo-O brings his right hand). It is said the Kurikara Ryu (倶利伽羅龍) changed its figure to this fire. It is said Fudo Myo-O (不動明王) brings this sword. Fudo Myo-O is a protective god in Buddhism, particularly Japanese Shingon Buddhism. This god was also known as a god of wars.
