The Girls' Division of Okinawa Normal School and the First Okinawa Prefectural High School for Girls were also known as "Himeyuri no Gakuen". In July 1944, the students, who were supposed to spend their summer vacations at home, were called back to school to prepare for the coming war and to fulfill their duties as subjects of the Imperial State. The fate of the girls and teachers awaited them as the American army attacked.
