With the advent of the modern state, the concept of a“motherland” has been becoming a crystal clear notion to many people around the world. However, sometimes it is not the case for some people, including not only the emigrants, but also the peripheral people who have never left their hometown. As a semi-independent kingdom influenced hugely by China and then Japan for centuries, Ryukyu experienced the earth-shaking “modern impact” in the late nineteenth century. It brought unexpected difficulties to the self-identity formation for the local people, and created an inconceivable and dramatic effect on the notion of“motherland” in Okinawan society. The“modern impact”includes two aspects. Firstly, with changing the name from Ryukyu to Okinawa, the timely annexation by Japan in the end of the pre-modern era made “Ryukyuan Consciousness”lose her opportunity to develop into “Ryukyuan Nationalism”. Secondly, the thorough Japanization policy carried out through Okinawa at the time restructured the culture and identity of the area. In search of the identity for themselves, a unique phenomenon manifested itself in the society of Okinawa for the last hundred and twenty eight years. Such characteristic which is rarely seen in other areas is the alternative repetition of two waves of identity emphasizing Okinawan identity on one hand and stressing on becoming a Japanese people on the other. Furthermore, the paradoxical phenomenon on “motherland” in Okinawa is exactly a story telling the violent structure of a modern nationstate, and also the restriction of assimilation.
