On October 2, Genna 6 (1620), he was granted the honorary title of Echigo no Kami. He passed away in Nagoya on July 11, Meireki 2 (1656) at the age of 76.
Despite its impressive length, this blade is exceptionally well balanced and free from any awkward proportions, displaying outstanding workmanship.
