Antique Japanese Sword Katana Signed by Enju Kadokuni with Tokubetsu Hozon Certificate 


 This blade was signed by Kikuchi Jyu Kadokuni (菊池住門國). NBTHK certificate mentions it is categorized as Sue-Enju, meaning the blade was made during the early-mid Muromachi period. (Mid-15th century). Kikuchi Jyu signifies that Kadokuni resided in Kikuchi city in Higo province (today’s Kumamoto prefecture) when he forged this blade. The back of the tang says it was made in August, an auspicious day.

 He belonged to the school named Enjyu (延寿) school. Its founder was Enjyu Kunimura (延寿国村).

Enju School and Its Founder (Enju Kunimura)
 Enju(延寿) is the prestigious school name that especially flourished during the late Kamakura period-Nanbokucho period(Early-Late 14th century). Enju school was founded by Kunimura(国村), who is said to have been the grandson of Rai Kuniyuki, one of the most famous swordsmiths from Yamashiro province(Today’s Kyoto prefecture).

 Kunimura and his apprentices moved from Kyoto to Higo province(Today’s Kumamoto prefecture on Kyushu island) after being invited by the Kikuchi clan, who had an influential power in that region. It is said that the 10th head of the Kikuchi clan, Kikuchi Takefusa(菊池武房), had to find skilled swordsmiths who could forge strong swords to combat the Mongolian army. Back then, Japan was targeted by the Mongolian emperor, and Kyushu island was where the battle occurred twice(1274 and 1281). Kikuchi Takefusa brought Kunimura and his apprentices from Kyoto to prepare for the second attack from the Mongols. Since then, Kunimura and his sons served as Okakaekaji for this clan, exclusively forging swords for the Kikuchi clan, which ruled the Higo province back then. All the swordsmiths from the Enju school used the letter “国” (Kuni) for their maker’s name, such as Kadokuni.

 The descendant of this school founded the famous sword school named Dotanuki(同田貫). And there are descendants of the Enju school’s swordsmiths throughout the Edo period. That means Enjyu school has over 500 years of its history. Enju Kadokuni also kept the tradition of the sword-forging alive in Higo province during the Muromachi period.

 The name “Enjyu” is written as 延寿 in Japanese. If you translate the word literally, it means extending life span, which was construed as good luck among feudal lords. Therefore, swords were presented among Samurai as good gifts back then.

 Enju swordsmiths active during the Kamakura-Nanbokucho period are called simply Enju, while those who forged blades during the Muromachi period are called Sue-Enju. Kadokuni is categorized as a Sue-Enju swordsmith.


  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 is a relatively noticeable Kitae Ware on the Shinogi part of the blade. If you like to make sure of its condition, please feel free to contact us.

【 Blade】
Cutting Edge Length(Nagasa)69.9 cm(27.5 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.

 Waves and waterwheels are designed for this Fuchi Kashira. Gold is applied to these waterwheels and waterdrops. This Fuchi Kashira depicts the scenery of people’s lives. The waterwheel was developed as a familiar tool for daily life, and its design was often used for Kosode (小袖, a kind of traditional Japanese costume) in the Edo period. The Tsuchi (槌, hammer), which is similar to the Hishaku (柄杓, ladle), began to be drawn in the early Edo period. The waterwheel on which the hammers are drawn is called the Tsuchi Guruma (槌車). Since a hammer is a tool for hitting stakes, and “hit” is said Utsu (打つ) in Japanese, it is likened to the figure of a Samurai who hits the enemy. Hitting enemy is expressed Teki-Wo Utsu (敵を討つ) in Japanese.

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

 The figure of the Kani (蟹, crab) standing on a water plant is the motif of this Menuki. Crab’s body and waterdrops are painted with golden color. As crabs walk sideways, they were compared “Oukou Kunshi (横行君子),” which means to stick to one’s intention against authority. Samurais might have felt the strong will that they would not bow before power from this motif.
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 antique Tsuba has Kozuka and Kougai holes. It has a texture like a rock surface due to its uneven surface and slightly irregular shape. About the design, you would find a crab and a Tonbo (蜻蛉, dragonfly). We think the crab is aiming to cut the dragonfly’s body with its scissors. The dragonfly does not seem to be able to see the crab, and it appears that he has not yet noticed the crisis approaching himself. It is a scene with disturbing tension.

 Dragonfly has been inhabiting since a long time ago in Japan. As they bag preys quickly, its heroic figure was 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 pleased. Allow was one of the Samurai’s primary weapons. 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 Samurais battlefields.

KougaiKougai is the equipment for Samurai to arrange or fix his hair style. It is stored in the Kougai Hitsu (groove of the sheath of the Japanese sword).

A kind of plant is designed for this Kougai. Its flower shape looks similar to poppies. Its petals are colored with silvery paint, and leaves and a bud are colored with golden paint. The fading of the colors tells us that this tool has a long history and was often used.

Saya Saya is the scabbard for the Japanese sword.
