In recent years, with the territorial dispute between China and Japan, the research on Okinawa's national subjectivity and cultural themes and its achievements have been increasing in China. However, research on post- World War II Okinawa literature is still not mature. The theses, which analyze Okinawa’s history, religion, folklore, culture, and even the potential consciousness of Okinawa, people since ancient times from the perspective of post- World War II Okinawa literature is especially rare. When we study the post- World War II Okinawa literature, it is important for us to ignore Oshiro Tatsuhiro (1925-2020), the first Okinawa writer, who won The Akutagawa Prize, the highest honor in Japanese pure literature. Oshiro Tatsuhiro's literature not only records the relationship between China and Ryukyu with a strong sense of history and humanistic sentiment, but also is praised because of his distinctive Okinawa character, and it also has its own place in the field of "Japanese literature." In a sense, we can also refer to the literature of Oshiro Tatsuhiro as a cross-nation and mixed literature.
