光田健輔
Among the Japanese prefectures, leprosy had the highest incidence in Okinawa Prefecture in 1925, 1935 and 1940. The Okinawa Government was inconsistent concerning the establishment of leprosaria. In 1931, Miyako Hoyoen Sanatorium was established on Miyako Island, but it was met with strong opposition from the mainland Okinawans. Rioting and burning of houses of leprosy patients occurred. With the help of various organizations and individuals such as Kensuke Mitsuda and Fumio Hayashi, the Kunigami Airakuen, now the Okinawa Airakuen Sanatorium, was established due to the efforts and leadership of Keisai Aoki.
