During the late Kamakura period, there lived a famous swordsmith known as Masamune whose renown as a swordsmith was so great that even long after his passing the term “Masamune” was used to describe any fine sword. Even today, the Masamune Prize is awarded to swordsmiths of outstanding skills in their craft. In Yasuji Murata’s cutout animation The Monkey Masamune a humble messenger is rewarded with the gift of a Masamune sword when he saves the life of a monkey and her child.
