Previous answer is
Mumei(Unsigned) (Aoe).
無銘(青江)

Features: This Aoe work is solidly built, heavy in weight, and a healthy sword.
It has recently been designated as Juyo Token.
From the extended kissaki, it is likely judged as a work of the Nanbokucho period.
Aoe is a school that continued from the Kamakura period (1185–1333) into the Nanbokucho period (1336–1392).
The sayagaki bears the inscription “Aoe Tsunetsugu” and appears to date from the early Showa period (1926–1989).
We have rarely seen such a solidly constructed piece, and the workmanship is excellent.
