光田健輔
Born in 1874 in Tokyo, she began to work for leprosy patients in 1901. Kensuke Mitsuda made a special leprosy ward called "Kaishun Byoshitsu" in "Tokyo Metropolitan Yoiku-In" which was established by Tokyo City (director was Eiichi Shibusawa) in 1901 and she became the nurse in charge of the ward. At that time she helped Kensuke Mitsuda to do autopsy late at night. At the start of Zensho Byoin, Tama Zenshoen Sanatorium, she was made the top nurse in 1909. She became the nurse director of the sanatorium in 1924. At the start of the Zensho Hospital, there were only 3 physicians and five nurses. She devised a portable boat-like bathtub for washing leprosy patients and her devotion and treatments of patients by the Mitsuda fashion were well appreciated. She retired in 1936 and died in 1947. Her photographs were found in a book entitled "The 120 year history of Kouyama Fukusei Byoin". In another book, Fumio Hayashi wrote a chapter on Ishiwatari with admiration when she retired.
