For a three week period from July 1, 1976, a field research was conducted in three rural villages (Takara, Ishikawa, and Oku) of the Okinawa main island to ascertain the conditions of diffusion of various innovations. The subjects emphasized in this report are the followings : Subject 1 : The speed of diffusion of innovations. Subject 2: Factors peculiar to Japan conducive for diffusion. Subject 3: Relativity of standard of measurement predicting innovation. Subject 4 : Expansion of marital mobility and stability of those brides being married in. Subject 5 : Interaction of two value perceptions relating to the holding of Ocean Exposition 1975. For each of the above subjects, the following generalizations will be presented. Generalization 1: The commencement of innovation adoption is earlier in villages near a city than in remote villages, Generalization 2 : In a situation where a child raised in povorty leaves the village and acquires an income outside of the village, the parent-child bond becomes a factor for diffusion of a particular innovation in the village. Generalization 3: For prediction of innovation, some absolute standard cannot be used for its measurement but a relative stdndard should be used. Generalization 4: Women of marrying age do not desire to remain in their village but prefer to find a mate outside the village. In remote villages undergoing population out-migration, there is almost no case of bride coming in; in villages near a city, the location of nativity of the incoming bride is on an expanding trend, but as an innovation them- selves, the brides, inspite of the village solidarity favoring exclusionism, are managing to gain stability. Generalization 5: When a forced innovation as the Ocean Exposition 75, the justification of which rests in the fact of it being an important governmental project, is established with the villagers having have to sacrifice their traditional way of life, interaction between the concept favoring exchange of values on the part of those promoting the project and that emphasizing villagers' notion of "lye" as derived from their view of traditional values on the part of those having to cooperate can be seen.
