Features:
Jirōtarō Naokatsu was a swordsmith born in Yamagata. He moved to Edo and studied under Naotane, who was also from Yamagata. He subsequently married Naotane's daughter and became his adopted heir. Like his master, Naokatsu was retained by the Akimoto family, the lord of Yamagata clan.
It is believed that during Naotane's later years, Naokatsu produced many substitute works on his behalf. Naotane passed away in 1858, and Naokatsu died the following year. As a result, relatively few works by Naokatsu are known today.

Koshirae:
Tsuba: iron base carved with chrysnthemum and paulownia.
Fuchi: Shakudo base
Kashira: made of horn
Menuki: a design of a figure and a dog.
