Antique Japanese Sword Katana attributed to Kouda with Tokubetsu Hozon Certificate 

【Description】

Summary

 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.

 

  It 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 few visible Kitae Kizu on this blade. If you like to know the detailed condition, please feel free to contact us.

【 Blade】
Cutting Edge Length(Nagasa)73.3 cm ( 28.8 inches)
Curvature(Sori) 1.8 cm ( 0.7 inches)

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 has a unique design. It has irregular patterns with a complex mixture of stripes and spots. It seems to be that multiple layers of different metals are folded on each other, creating a design that looks like the cross-section has been carved out.

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

 The Tonbo (蜻蛉, dragonfly) is the motif of this Menuki. The mottled pattern on the wings is somewhat similar to the design of the Fuchi Kashira. This insect has been inhabited for a long time ago in Japan. As they bag preys quickly, its heroic figure was sometimes the object of belief. During the Warring States period, the dragonfly was called the Kachimushi (勝ち虫, winning insect) because of its fearless character; it moves only forward, not backward. Above all, the dragonfly pattern combined with the iris flower or the arrow was favored. Allow was one of the Samurai’s primary weapons. The iris flower is called the Shoubu (菖蒲) in Japanese, and there is the word Shoubu (勝負), which means battle. So, “Shoubu” (菖蒲, iris flower) and Shoubu (勝負, fight) those two words have the same pronunciation; therefore, the iris flower pattern reminds Samurai battlefields.
   
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. 

 Yotsu-Mokkou-shaped iron Tsuba that has Kozuka and Kougai holes. Its origin is the shape of eggs in a nest. When a quince (it is written 木瓜 in Japanese) is cut into round slices, its cross-section looks similar to this shape; therefore, it was named Mokkougata Tsuba. Yotsu-Mokkougata (四ツ木瓜形, a combination of four Mokkou shapes) Tsuba is often seen, same as this Tsuba.

 About the design, a mesh pattern is engraved on the entire surface. This type of tracery is categorized as the Yabane Ajiro (矢羽根網代) and is one of the most famous netlike patterns. Yabane (矢羽根) is feathers attached to the back of an arrow to make it fly straight. Many Samurai loved the arrow pattern as an arrow goes forward powerfully. Since ancient times, arrows have been used as a weapon, which is the original purpose of this item. Additionally, each home displayed decorated arrows wishing it would exorcize evil spirits in the house. This talisman is called the Hama-Ya (破魔矢) in Japanese, and this custom is still kept today.

 Although most of the colorings have already faded due to aging, you could find several plants are depicted on this Tsuba. For example, bamboo (or bamboo grass) is designed at the lower side of the front. Bamboos grow neatly towards the sky, and it is vital so that this motif represents nobility and strength. According to a foreign legend, Houhou (鳳凰, Fenghuang) eats bamboo fruits; therefore, bamboo has been considered a sacred plant. Also, as it keeps its green color even in cold winter, people thought the bamboo pattern shows eternity and longevity.
 

Saya Saya is the scabbard for the Japanese sword.  

* Please keep in mind that there is visible trace of restoration near the Koiguchi area. If you like to see the detailed condition, please feel free to contact us.
