岩松家純
A Muromachi-period warrior descended from the Nitta clan. In 1469 he built Kanayama Castle, moved in, and reunited the divided Iwamatsu family.
A ground-breaking ceremony for Kanayama Castle was held on February 25, 1469, and that August Iejun left the Uesugi camp at Ikarako (now Honjo, Saitama) and moved into the new castle. He died in 1494 at the age of 86.
