Antique Japanese Sword Katana Signed by Hizen Koku Yoshikane with Tokubetsu Hozon Certificate
This blade was signed by Hizenkoku Yoshikane (肥前国吉包) during the late Edo period (Bakumatsu era). Hizenkoku is the name of the domain in today’s Saga prefecture. Yoshikane belonged to Tadayoshi school and is known as an apprentice of the 8th-gen Tadayoshi (8th head of the school).
It is assumed that Yoshikane dedicated his career to helping the 8th-gen Tadayoshi (his master) with his highly skilled craftsmanship. There aren’t many remaining blades made by Yoshikane. However, Yoshikane was one of the most skilled sword makers in Hizen domain during the late Edo period, aside from the 9th-gen Tadayoshi and Yoshimune. Those three swordsmiths are known as Hizen Sanmeiko (Three prominent swordsmiths in Hizen domain ) during the Bakumatu era (the end of the Edo period).
According to available records, Yoshikane forged blades for Shima Yoshitake and Eto Shinpei, both of whom were Samurai participating in Sagano no Ran (佐賀の乱), a civil war that happened in the 7th year of the Meiji era in Saga domain to protest against the newly founded Meji government. Based on this fact, the blades forged by Yoshikane were demanding and popular among Samurai warriors in Hizen during the late Edo period.
The founder of Tadayoshi school
The first-gen Tadayoshi was born and raised in the Saga domain. In 1596, under the domain’s order, he went to Kyoto to learn the sword-forging technique from Umetada Myojyu(埋忠明寿), one of the greatest swordsmiths in the early Edo period. He improved his craftsmanship and returned to the Saga domain two years later (1598). The first head of the Nabeshima clan, Nabeshima Katsushige, appreciated the work of the first-gen Tadayoshi very much. Then, Katsushige appointed him as his Okakaekaji, a swordsmith who exclusively forged swords for a specific domain or clan. And Tadayoshi started to stay near Saga castle, which is the headquarter of the Nabeshima clan. And, he founded Hizen Tadayoshi school, which trained more than 100 swordsmiths during the Edo period. Yoshikane is one of them.
The swordsmiths in the Hizen province worked under the auspices of the Nabeshima clan such as Yoshikane. They could produce beautiful Jigane-patterned blades, also known as Hizen To, using and mixing carbon steel made in western countries. Hizen Koku had been flourishing by international trading. The geographic location of this domain made it possible to have easy access to western carbon steel.
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.
*Please keep in mind that there are a couple of Kitae Kizu and black rust on this blade while they are all minor. If you like to know the detailed condition, please feel free to contact us.
Cutting Edge Length(Nagasa)： 66.2 cm (26.0 inches)
Curvature(Sori)： 1.3 cm (0.51 inches)
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process

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.
The surface of this Fuchi Kashira is worn, so currently, it is challenging to see its detail. We assume a combination of a dragon and clouds is engraved on it. Initially, the dragon was an imaginary creature found in ancient foreign traditions or 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 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.
Clouds bring rain and snow, and their movements significantly affect the day’s weather. Due to its supernatural power, a theory says that gods, spirits, and dragons dwell in the clouds. In Japan, a religion worships the dragon as a water god. It might be one of the reasons why this combination design is often seen even in sword mountings.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Chrysanthemums are the motifs of this Menuki. Golden paint was applied to their petals and remains relatively in good condition. A long time ago, chrysanthemums were used as a medicine for obtaining a long life in the continent, and it was brought to Japan with this thought in the Nara period (648-781). The chrysanthemum symbolizes autumn, and people have greatly appreciated it since ancient times. This palnt has been likened to the sun as its petals form radially. That is why this flower pattern is treated as the symbol of perpetual youth and longevity or good health.
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.
This Tsuba is decorated with auspicious theme. A landscape is depicted on its front. We could find a classical design called the Ichi-Fuji Ni-Taka San-Nasubi (一富士 二鷹 三茄子, one Mt. Fuji, two hawks, and three eggplants).” In Japan, these are considered auspicious signs if they appear in the first dream of the new year. There are several theories as to why these motifs were chosen. A view says that it is because Tokugawa Ieyasu (徳川 家康, 1543-1616), who opened the Edo Shogunate, loved Mt. Fuji, falconry, and the first eggplant of the season. It is also said that each object’s name compared to a good meaning word as follows: Fuji (富士) and Buji (無事, safe, safely), Taka (鷹) and Takai (高い, high), and Nasu (茄子, eggplant) and Nasu (成す, make, achieve). This Tsuba’s maker might have incorporated this design because of his wishes for the success of his essential work or his desire for a successful career.
On the backside of this Tsuba, Japanese letters are engraved. They are arranged one letter at the top, bottom, left, and right. And if we rearrange them according to the actual words, it could quote the following expression: 長命富貴 (Choumei Huuki). It means one must live a long life, have wealth, and have a high social status. The letter “富” means having a lot of assets. And the letter “貴” means high status.
Saya： Saya is the scabbard for the Japanese sword.

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.
