The first superintendent of the Hsi-Kou Health Care Center (Songshan Sanatorium) was Yoshizawa Takanosuke, who was succeeded by Shimomura Hirojiro. For the 30 years of the Period of Japanese Rule, Songshan Sanatorium had 7 superintendents, some of whom had served for 9 years and some had only 1 year. However, no records could prove the length of their services. In 1945 (the 34th year of the Republic of China), the Government reorganized the institution and renamed it the Taiwan Provincial Songshan Sanatorium. On July 23, 2013 (the 102nd year of the Republic of China), when the Bureau of Health and Welfare was upgraded and renamed into the Ministry of Health and Welfare in accordance with the order of the Executive Yuan, the Sanatorium was officially renamed into Chest Hospital, Ministry of Health and Welfare.
