Mark with Japanese mark: 野村正光 "Nomura Masamitsu" | #433301

野村正光 "Nomura Masamitsu". This mark comes from a "tsuba", a sword guard designed to protect the hand from contact with the blade and an opposing sword. It was made by Masamitsu, who worked as a "soukenkinkou" in the Nara line of the Nomura house. Soukenkinkou is the Japanese name for metalworkers who design accessories for bladed weapons.
