Antique Japanese Sword Daisho(Katana&Wakizashi) Signed by Kunisada with NBTHK Tokubetsu Hozon Certificate 


These Katana& Wakizashi were signed by Kawachi Daijyo Fujiwara Kunisada(河内大掾藤原国定) in Aizu province (today’s Fukushima prefecture) during the early Edo period(Kanbun era: 1661-1673). Kunisada belonged to Aizu Kanesada school, one of the most prestigious schools in the region, flourishing during the Edo period.

Aizu Kanesada school was founded by Kanesada, who had forged swords in Mino province(Today’s Gifu prefecture) until the Keicho era(1596-1615). This Kanesada was the grandson of Noshu Izumi no Kami Kanesada(濃州和泉守兼定), a renowned swordsmith in Mino province.

Kanesada relocated to Aizu from Mino to serve Gamo Ujisato(蒲生氏郷), a powerful feudal lord who worked for Oda Nobunaga. And, Kanesada founded Aizu Kanesada school there.
Aizu Kanesada school lasted 11th generations by the end of the Edo period. Kunisada, who signed this Katana& Wakizashi was a younger brother of the third-gen Aizu Kanesada(Nyudo Kanesada).

What is Daisho?
Daisho is a pair of two Japanese swords Samurai carried. During the Edo period, having Daisho in public places was considered social status for Samurai. Furthermore, Samurai were required to wear them under the law back then. Daisho is written as 大=Big and 小=Small. Dai part means Katana, and Sho part means Wakizashi. 

These Katana& Wakizashi blade are 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.

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.
