Antique Japanese Sword Katana Unsigned Kashu Iekatsu with NBTHK Hozon Certificate


This blade is attributed to work of Kashu Katsuie, a reknown swordsmith from Kaga province(today’s Ishikawa prefecture).

The swordsmith name “Katsuie” (勝家) lasted several generations from the middle of the Muromachi period to the early Edo period (1450s-1650s). The first generation Katsuie was originally from Mino province(today’s Gifu prefecture). However, he and his apprentices moved to Kaga Koku(Today’s Ishikawa prefecture) in the middle of the Muromachi period(1450’s). They founded a Darani(陀羅尼) school after being hired by the monks who lived there.

Later on, from the second generation, Katuie started to serve a famous feudal clan, Maeda clan. It was honorable for any swordsmiths to serve a feudal clan exclusively.Maeda clan was originally a retainer of Oda family, who ruled Owari province. (today’s Nagoya area in Aichi prefecture). The first head of the Maeda clan was Toshie Maeda. He climbed the social ladder of Samurai society, and he became the feudal lord of Kaga Province(today’s Ishikawa prefecture). He had a vast rice fief that fed 100 million grown-up adults, which is called Hyakuman Goku. The Maeda clan was one of the most influential families in Samurai history. Toshie Maeda had a close tie with Oda Nobunaga and Hideyoshi Toyotomi.

Based on this blade’s characteristic, we estimate that it was forged by early-gen Kashu Katsuie in the late Muromachi period, when there was fierce rivalry between strong feudal lords. This period is also known as SENGOKU JIDAI.

You can see three holes on the tang(handle), which signifies the blade was shortened at least twice since the sword was forged. We assume it used to be a relatively long sword. We also believe that the signature was cut due to the blade’s adjustment, and it appears to be the Mumei(Unsigned) blade.

This sword has a Hozon certificate issued by NBTHK. This authentication paper was only given to Japanese swords, worth preserving by Nihon Bijutsu Touken Hozon Kyokai(the Society for the Preservation of the Japan Art Sword). The blade also comes with a beautiful set of Katana style Koshirae.

NakagoNakago is the tang of the Japanese sword.

Japanese swordsmiths left the black rust on the tang on purpose to prevent red rust while the tang is in its handle. And the discoloration of the tang was created over time, which is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

【Other Details】

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Sabbard), Tsuka( Handle), Tsuba(Handguard).


Fuchi-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt. 

 According to its signature, this Fuchi Kashira was made by Yanagawa Naomasa (柳川 直政); who was the second of Yanagawa school. He worked actively in the middle of the Edo period (1681-1780). He learned under Yoshioka Inabanosuke (吉岡 因幡介) and Yokoya Soumin (横谷 宗眠). Naomasa was good at the sacred animal motifs engraving with the Takabori technique on the Shakudou (赤銅, the mixture of copper and gold) material.

 Karajishi (唐獅子) is designed for this Fuchi Kashira. Shishi (獅子) means a lion in Japanese, and Kara-Jishi is a lion brought from China 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, 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).
Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 Two men are designed. One of them is colored with gold, and the other one is colored with silver. Perhaps they each have a sword, and it seems they are just trying to defeat the other. The details such as facial expressions or wrinkles of their clothes are engraved elaborately. You would enjoy its maker’s thorough work. 

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. 

 Circle-shaped Tsuba made from iron. A golden metal was applied in Kozuka and Kougai holes; it gives a gorgeous appearance for this work. Flower patterns are designed. Each of them has five petals in double. The Karakusa (唐草, arabesque) pattern surrounds these flowers. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. If you focus on the center part of this Tsuba, you will find that it is signed. Although its signature has already worn down due to aging, we could read three letters on the left side of Nakagoana (茎穴, the center hole of a Tsuba). It is written as “駿河作 (Suruga Saku)”; it means Suruga made this Tsuba. We could not assert definitely, but there was a Tsuba maker family whose family name was Suruga. This school initially did well as an armor maker, and later they moved to Bizen (備前, today’s Okayama prefecture) and worked for the Ikeda family. So we would speculate that this Tsuba was possibly made by one of this school’s makers.  

SayaSaya is the scabbard for the Japanese sword.
