Antique Japanese Sword Katana Signed by Kuniteru with Tokubetsu Hozon Certificate 


This blade was forged by Izumi Daijyo Fujiwara Kuniteru(和泉大掾藤原国輝) in Iyo province during the Tenmei era(Late Edo period:1781-1789) according to the NBTHK’s appraisal.
The swordsmith’s name Kuniteru lasted a few generations. Based on the appraisal, we believe it was signed by the seventh-gen Kuniteru, who was the last one.
Izumi Daijyo is the name of the title given to this swordsmith from the first gen. Iyo province is located in today’s Ehime prefecture(Shikoku island). Kuniteru school was a prestigious school that lasted from the early late Edo period (Mid 17th century- Late 18th century).

The first-gen Kuniteru was an apprentice of Sanko Nagakuni, forging swords in Akino province(Hiroshima prefecture). After being hired by Kato Yoshiakira, the head of the Matsuyama clan, Nagakuni moved to Iyo province, and Kuniteru followed him. However, Nagakuni eventually left Iyo province, but Kuniteru stayed in the region. Later on, Kuniteru received Izumi Daijyo in the 9th year of the Kanbun era(1668). Since then, each gen of Kuniteru received this title in their career. The most famous generations were the first, second, and seventh generations.

This blade has a groove, which enhances its aesthetic beauty. And, it comes with beautiful Fuchi Kashira, Tsuba, and Menuki(decorative sword mountings).

This blade 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.

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.

A kind of bird is designed for this Fuchi Kashira. Copper is hollowed out in the shape of birds, and the color of the material at the bottom of the Fuchi Kashira is visible. These birds might be the Houou (鳳凰, Fenghuang). The Houou is a member of four fantasy animals, which is called “Shirei (四霊)” with Kirin (麒麟, Qilin), Kame (亀, Turtle), and Ryu (龍, Dragon), and it is a god beast looks like a combination of chicken and peacock. The Houou was considered an auspicious sign in ancient China, and it was believed that the Houou would show up when the brilliant emperor appeared. People appreciate its graceful shape in Japan. According to a theory, Houou’s body matches the celestial body: its head was considered to be the sky, its eyes to the sun, its back to the moon, its legs to the earth, and its tail to the planet. Therefore, some people thought the Houou would connect this world and the heavens.

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

This Fuchi Kashira’s motif is the Kara-Jishi (唐獅子). The gold-colored metal is applied to them and makes a gorgeous look for this work. Comparing these two Kara-Jishis, it seems they see each other. They are engraved in semi-three-dimensionally so that they look very vibrant and lively. Shishi (獅子) means a lion in Japanese, and the Kara-Jishi is a lion brought from the Continent to Japan in the Toh period (唐, Tang dynasty, 618-907). The Kara-Jishi typically has curly hair for its head, neck, body, and the tale. In Buddhism, the Kara-Jishi is regarded as a symbol of wisdom, and Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, Kara-Jishi originates from Komainu (狛犬, stone guardian dogs that exorcize evil spirits).

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 Tsuba that has a Kozuka hole. Mokkou shape, its origin is a figure of eggs that are rest 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 (a combination of four Mokkou shapes) Tsuba is often seen as this work is categorized.

This Tsuba’s edge is framed with a glossy metal plate that imitates a rope-like pattern. It seems the golden metal was initially applied to this plate part. This decorative technique gives the Tsuba a gorgeous beauty. It also has practicality, such as preventing the wear of the edge part. Also, it prevents the wear and tear of the Kimono (着物, traditional Japanese costume) if the edge damages it by touching the cloth.

The Ougi (扇, fan) is the principal motif of this Tsuba. Since a cloud pattern surrounds fans, they are cut off in these clouds’ shapes. Each fan is decorated with different designs. For example, if you focus on the upper side one, you will find maples flowing into the water; it shows us a quaint autumn scene. The fan design has been favored as an auspicious pattern that represents development and prosperity. A fan has a characteristic shape that is called Suehirogari (末広がり) in Japanese. Based on the idea that this shape implies a perspective of the future, people appreciate this design. The fan pattern also represents wealth because it was once available only for high-ranked people.

Saya Saya is the scabbard for the Japanese sword.
