Since islands of Okinawa was incorporated into Japan, many Okinawan people have been in a little difficult position. For example, the migrants from Okinawa in the cities of mainland Japan (Hondo) were often discriminated in the employment opportunities. And because islands of Okinawa was ruined in World War II, many Okinawan migrants were left in the mainland, and they had to live in the postwar severe situation. In this paper, I will examine the urban lives of Okinawan migrants in Hyogo prefecture (especially postwar Amagasaki, Takaradsuka, Itami and Kobe city) and their various forms of networks, groups and places to live in and to resist oppressed situation. The association of people from Okinawa prefecture (Okinawa-Kenjinkai-Hyogoken-Honbu) was one of the most cohesive group, it was made by `Okinawa' as a social category and as a symbol of concentration for some social and political purposes. In Amagasaki and Takaradsuka city, these cohesions like Kenjinkai had made it possible for some assemblymen who were native of Okinawa to win the local elections, for example. When the people who lived in the concentrated areas had some political purposes, these areas became the cohesive places to resist their opponents. But these cohesions were ad hoc. Because each migrants lived in different geographical and social context, their each individual living strategies and tactics were complicated, and each migrants had extended their own personal networks which included neighbors who were not native of Okinawa. So even in their concentrated areas, their individual social and political senses were not always in unison. Okinawan migrants had become urbanites in urban settings. It is said that discrimination in the employment opportunities was to some extent eased in the high-growth period, so their lives have changed for the better. And the main role of Kenjinkai have become enhancing mutual friendship.
