Antique Japanese Sword Katana Signed by Fujiwara Kunimasa with Tokubetsu Hozon Certificate 


 This blade was signed by Yoshu Fujiwara Kunimasa (予州藤原国正), also known as Suruga no Kami Fujiwara Kunimasa. According to its NBTHK Tokubetsu Hozon appraisal, it was made during the Shinto era (Early-Mid Edo period). Yoshu, also known as Iyo province, was the name of the province located in today’s Ehime prefecture.

 The maker’s name Kunimasa lasted a few generations from the early-late Edo period (Early 17th-Late 19th century). Based on the characteristic of this blade, we assume it was forged by the first-gen Kunimasa, who was active during the early Edo period (early-mid 17th ).

 The birth name for the first-gen Kunimasa was Nishimoto Ichiemon. He was initially from Tosa province (Today’s Kochi prefecture) and moved to Uwajima domain in Yoshu (Ehime prefecture).

 In the 5th year of the Kei-An era (1653)Kunimasa started to serve Date Hidemune, who controlled Uwajima domain. Hidemune was the first son of Date Masamune, one of the most famous feudal lords during the warring state period. And, Kunimasa became a Hanko (藩工), exclusively forging blades for this domain.

 In the middle of his career, he went to Edo city to become an apprentice for Yamato no Kami Yasusada, one of the most renowned swordsmiths during the early Edo period. He was able to master excellent craftsmanship from Yasusda and received the honorable official title of Suruga no Kami in the 4th year of the Kanbun era (1664). After finishing the apprenticeship, he moved back to Iyo province. He died in the second year of the Houei era (1705).

 The maker’s name Kunimasa lasted a few generations until the end of the Edo period. According to available records, his son became the second-gen Kunimasa in the 10th year of the Genroku era (1697). And the 8th generation Kunimasa is said to be the last one, and he was active during the Genji era (1864-1865).


  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.

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.

 Dragons are designed on this Fuchi Kashira. It seems golden paint was initially painted on several parts, such as dragons’ eyes, claws, and beards. This coloring makes a color contrast of gold and black. Originally, a dragon was an imaginary creature found in ancient foreign traditions or myths. Furthermore, it is regarded as a symbol 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. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. The dragon motif is often seen in sword mountings. It shows that many Samurai favored this dignified beast design.

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

 We cannot see the details and the entire shape of this Menuki due to the Tsukamaki thread. It is challenging to determine what the motif is. We think one side is probably the figure of a horse riding on clouds. And on another side Menuki, we could find an object which could be seen a sword. We estimate that a Samurai was initially engraved on this side. Horses have been active on battlefields for a long time.

 After the age that Samurai appeared, wearing large armor or performing archery riding a hose became martial arts. Equestrian tactics became the pillar of military action and security activities. According to a theory, that is why the Japanese sword began to have a curve to make it suitable for slashing (the Japanese sword was straight in the beginning). In this way, horses were closely related to Samurai; therefore, it is understandable that it was incorporated into sword mountings’ designs.

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 oval-shaped Tsuba has an ornamental appearance thanks to gold-color decoration. Golden metal was applied to Kozuka and Kougai holes. In addition, the Mimi (耳, edge of Tsuba) is framed with the same golden metal. It is a processing method that combines both aesthetics and practicality to prevent damage.

 About the design, this Tsuba depicts a scenery of a battlefield. You would find figures of Samurai warriors on the front. They were clad in armor. And they glared at each other with a sense of tension as if they were about to slash. The brave figures of warriors who risk their lives on the battlefield are expressed on this small screen.

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1017738)

  NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan. They authenticated the blade on Jun. 3rd in the 4th year of Reiwa (2022) . They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
