Kaganoi Shigemochi (加賀井 重望, 1561 – August 27, 1600) was a Japanese samurai of the Azuchi-Momoyama period, who served the Oda clan. He ruled Kaganoi Castle. During the Battle of Komaki and Nagakute, Shigemochi fought under his father Shigemune, who was attached to the forces of Oda Nobukatsu. Soon after, Kaganoi Castle was surrounded by the forces of Toyotomi Hideyoshi; Shigemune surrendered, and Shigemochi was employed by Hideyoshi as a messenger, receiving a stipend of 10,000 koku. He also possessed a blade made by Muramasa, which Hideyoshi bestowed on him in 1598.
