Antique Japanese Sword Katana Signed by Yasutsuna with Hozon Certificate
This blade was signed by Awa no Kami Yasutsuna (阿波守康綱), who belonged to Kishu Ishido school. He was active in sword-forging during the Kanbun era(early Edo period: 1661-1673). He was an apprentice of the first-gen Bitchu no Kami Tachibana Yasuhiro.
Kii koku is the name of the province located in Wakayama prefecture today. He is known as one of the most famous swordsmiths from the Kishu Ishido school during the early Edo period. There was also a record of Yasutsuna forging in Osaka.
Ishido school was initially founded by Sukenaga, an offspring of Ichimonji Sukemune, who had created Fukuoka Ichimonji school in Bizen province(Today’s Okayama prefecture).
During 1492-1501(Mid Muromachi period), Sukenaga and his school moved from Bizen province to Omi province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido. It was common for a swordsmith to name add where he lived to his maker’s name back then.
As of the early Edo period, many Ishido swordsmiths in Omi province moved to other parts of Japan. There are four major branches: Edo, Osaka, Kishu(Wakayama prefecture), and Chikuzen(Fukuoka prefecture). Omi Ishido school was the origin of whole other Ishido branches that flourished during the Edo period.
Following this trend, Bitchu no Kami Tachibana Yasuhiro, the master of Yasutsuna, moved to Kishu province from Omi province. It is said that Yasuhiro was the founder of Kishu Ishido school. Yasutsuna and his master forged swords near Wakayama castle in Kishu province. Judging from the fact that Yasutsuna worked for this skilled master, his craftsmanship must also have been excellent.
This blade is appraised as a Hozon Token(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, well preserved with artistic value.

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 has a simple look and has a beautiful reddish-gold color. Although it does not have engraved motifs such as animals or plants, this coloring makes enough its decorativeness. And its simple design matches well with other sword mountings of this sword. Also, if you focus on the surface of this Fuchi Kashira, you will find it has a rough surface. Please enjoy these details.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Golden Menukis are seen from the gaps of the Tsukamaki thread. Regarding their elongated bodies, we think dragons are the motif. Initially, the dragon is an imaginary creature found in ancient 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, belly is the Mizuchi (蛟, mythical animal in Japan which looks like a snake and have 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.
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.
Circle-shaped Tsuba that has a Kozuka hole. If you focus on its surface, you will find that thin lines are engraved with a file, and these lines are radiated from the center of the Tsuba. Most of these straight lines are not clearly seen now due to aging. However, we hope you will enjoy it as an antique texture. This type of line carving technique is called as the Amida-Yasuri (阿弥陀鑢), because these lines look similar to the halo of Amida Nyorai (阿弥陀如来, Amitabha Tathagata).
Two different flower petals are designed for this Tsuba: cherry blossom and Japanese apricot blossom. Both of them have been cherished in Japan since ancient times. Cherry blossom is one of the seasonal things of spring. A theory says that the god of grain exists in cherry blossoms. Therefore, this flower pattern has been treated as the symbol of a plentiful harvest. And Japanese apricot blossom symbolizes the power of perseverance and vitality as it comes out in the cold season.
There are two Habakis for this blade. One is for Shirasaya and the other is for Koshirae. The Habaki below is for Koshirae.
Saya： Saya is the scabbard for the Japanese sword.
