Antique Japanese Sword Katana Signed by Hizenkoku Yoshikane with
Tokubetsu Hozon
Certificate
【Description】
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). Judging from the back of the signature, it was ordered by a man named Saneyori (実従). When you find the order’s name in the signature, it is called Chumon Uchi. We assume this man was a Samurai in Hizen Koku.
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 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.
Hizen Domain
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.
