Antique Japanese Sword Katana Signed by Echigo Koku Kanenori<br> NTHK Kanteisho Certificate


 This blade was signed by Echigo Koku Kanenori (越後国兼則), who was active during the early Edo period (Early-Mid 17th century).  Echigo Koku is the name of the province located in today’s Niigata prefecture. 

 Kanenori originally belonged to Echizen Shimosaka school located in Echizen province (today’s Fukui prefecture). The maker’s name Kanenori (兼則) lasted many generations from the early Muromachi period to the Edo period.

 The first-gen Kanenori is known as the founder of San-Ami school, one of the seven most famous schools in the Mino province (Gifu prefecture). The first-gen Kanenori forged swords during the Oei era (1394-1428). There are records where swordsmiths who signed as Kanenori moved to Echigo, Echizen, and Owari to meet the demand of strong Samurai after the Edo period. This Kanenori was one of them.

Echizen Shimosaka School

 It is said that the first-gen Yasutsugu was the founder of the Echizen Shimoasaka school. He was born in Shimosaka town in Shiga prefecture at the end of the Muromachi period (Late 16 century ). He built his career there until the beginning of the Keicho era(1596). However, he moved to Echizen province due to the relocation of the lord he served. He eventually was noticed and supported by Matsudaira Hideyasu, the third son of Tokugawa Ieyasu, who was the founder of the Edo government.

 Hideysu was the feudal lord of Echizen province during the early Edo period. With the support of Hideyasu, the first-gen Yasutsugu was able to establish the Echizen Shimosaka school. And his school’s fame became nationwide. By Hideyasu’s recommendation, the first-gen Yasutsugu became Okakaekaji for the Tokugawa shogun family, meaning that he exclusively forged swords for the Shogun family. Yasutsu was acknowledged by the first and second Tokugawa Shoguns, Tokugawa Ieyasu, and Tokugawa Hidetada.

 The first-gen Yasutsugu received 康(YASU) from Tokugawa Ieyasu and changed his maker’s name. He was also allowed to inscribe the holly oak symbol(family crest of Tokugawa) on the tang. The school flourished during the Edo period and trained many skilled apprentices. We believe Kanenori mastered superb level of the craftsmanship by belonged to this school. 

 Echizen province was prosperous during the Edo period, being ruled by the Echizen Matsudaira clan, a direct retainer of Tokugawa clan who ruled the Edo government. Many skilled swordsmiths moved to Echizen from different regions because of high demand among Samurai who lived there. Among them, there were many renowned swordsmiths who were originally from the Mino province (Gifu prefecture). They are called Echizen Seki swordsmiths.


*Please keep in mind that there are visible Kitae Kizu and black rust on the blade. Also, there is a couple of small chips near the Kissaki (tip). If you like to see the detailed condition, please feel free to contact us.


【 Blade】

Curvature (Sori): 1.51 cm (0.59 inches)

Nakago: Nakago 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-Kashira: A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.

 This Fuchi Kashira and the Tsuba we will mention later, both sword mountings are decorated with the same beast motif: dragons. While some colorings have already faded due to aging, golden paint is applied to these dragons. 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. The dragon was thought to reign at the top of all animals because of its odd appearance.

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

 The upper side Menuki, it is challenging to judge the motif of this Menuki by seeing from the gaps of the Tsukamaki thread. On the other hand, the lower side Menuki’s model is a man who brings a bow. He seems to hold a bow in his left hand and a stick-shaped weapon in his right hand, and his expression and posture suggest that he is probably running. The upper side Menuki is only partially visible, and we now estimate its model is an Oni (鬼) being chased by a man. Oni is a monster with a human body, horns, and fangs. They are usually harmful to people. However, they are sometimes helpful existence. This Menuki might have inspired some stories or folk tales.

Tsuba and Habaki: Tsuba 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. 

 The same as the Fuchi Kashira, this Tsuba’s design is related to the dragon motif. On this Tsuba, you would find the figures of two dragons on each side. They are arranged in a circle on the screen, as if chasing each other’s tails. Among dragon designs, there is the Ameryu/Amaryu (雨竜) motif. It is a kind of dragon who controls the rain. It is believed that an Ameryu would make rain in the proof when God is blessed. A theory says an Ameryu is the young figure of a dragon. This creature has been thought to be a small spirit who lives in forests. As mentioned above, their appearance has a similarity to a dragon. That is why they are sometimes depicted with a charming look compared to other kinds of dragons. Moreover, snake worship was common in Japan because the serpent deeply relates to the water god’s faith. It might be the reason why Japanese people love the Ameryu pattern.

Saya: Saya is the scabbard for the Japanese sword.
