Special feature: Miyoshi Nagamichi, born Miyoshi Toshiro lived at Matsuyama
in Iyo province is a grandson of Nagakuni. Nagakuni was a retained
swordsmith of Kato Yoshiaki. Nagakuni and his son Masanaga, the
father of Nagamichi went along with the Kato family when they moved
to Aizu in O-shu province in 1627. Nagamichi was born in 1633 who
was called Michinaga in his youth. Accepting Mutsu-Daijo in 1659, he
changed the name to Nagamichi. Mr. Asaemon Yamada, known as a
famous cutting tester ranked Nagamitsu Saijo-Owaza-mono in his book as one of twelve excellent swordsmiths at the point of
sharpness. Quite a few swords forged by Nagamichi survive with the result of the cutting test.
Nagamichi the First passed away in 1685, aged 53. The workmanship of this katana
shows a strong resemblance to Kotetsu who is a representative swordsmith of Edo-shinto.

From Aoi Art: Miyoshi Nagamachi was welcomed by Aizu samurai. The long way is
Nagamichi received the tremendous evaluation of the samurai of the 　
Aizu clan
It is the most highly evaluated swordsmith
As a result of his efforts to always produce sharp swords, he was evaluated by the samurai of the Aizu clan. In this work, there are small forging cracks on the blade near the Monouchi area on the back, but it is not noticeable and there is no problem.
By all means, we recommend the masterpiece called Aizu Kotetsu.
