What is the main setting of the book, The Girl With the White Flag?

The setting of Tomiko Higa's book "The Girl with the White Flag" is that of the island of Okinawa, on the southern tip of Japan. Okinawa is described as tranquil and beautiful, making the impact of war that much more jolting and disconcerting. Okinawa is one of the costliest battles for Japanese forces in World War II, and the death and destruction that follow occurs on a massive scale. Okinawa is where Tomiko Higa was born and grew up, and so her experiences of the war on the island are dutifully recorded in her book.
