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.

Quite a few swords forged by Nagamichi survive with the result of cutting test.
