Terumasa Nanjo (南條輝正) is Kinzo Ushiromiya's attending physician and long time friend. He was previously a medical practitioner on Niijima, however he has since mostly retired and left his hospital in the hands of his son, Masayuki Nanjo.

Background
During World War II, Kinzo Ushiromiya brought Beatrice Castiglioni to Nanjo's hospital. After this meeting, Kinzo and Nanjo became close friends. Due to his knowledge of the West and a common appreciation towards chess, Nanjo is one of the very few people Kinzo has ever opened his heart to.
