He was a very caring person and has collected the prisoners who deserve sympathy to make swords.
He was popular among the prisoners and the swords were made in serious manner.
In the neighborhood, there was a place for swords to be polished as well.
At the mean time, Nagamitsu, the head guard at the time, also made sword but Emura made better swords and done better polishing.
