The first generation was active at Nanbokucho period.
There is only few works with the signature, such as two generation(parent and son) Kuniyasu, Morishige, Morihiro and others.
There is also Shigekuni and Kuniyuki in the same generation.
Koshirae : Japanese Army Koshirae
From Aoi Art : Chiyoduru’s works are popular for marriage and celebration because of the auspicious name.
Daimyo feudal loads gave Chiyozuru’s works to their serrvants
as gifts and the servants kept them as heirlooms.
I imagine that a father put this heirloom blade into this Japanese
Army Koshirae for his son leaving for battle.
