Historical Background: In 1818, during the reign of Tokugawa Ienari, the 11th shogun of the Edo shogunate, the era name was changed from Bunka to Bunsei following the enthronement of Emperor Ninko.
This period saw the maturation of Bunka-Bunsei culture, with active cultural and artistic activities among the common people.
Generally, ura-mei inscriptions such as “A date in August, 1818” are rarely seen on Naminohira works; however, this sword bears such an inscription.
For this reason, it can be considered a rare piece.
