Masako Ogawa (小川 正子, Ogawa Masako, March 26, 1902 – April 29, 1943) was a Japanese medical doctor who worked at the Nagashima Aiseien Sanatorium. She wrote a book, "Spring in a small island" in 1938, about her experiences in persuading leprosy patients in remote areas of Japan into hospitalization. It created a sensation in Japan, and was made into a film. She was criticized for accelerating the "No leprosy patients in prefecture" movement and giving an impression that leprosy is to be feared.
