It will be considered from the perspective of network rent using a case of Cooperative Del Sole in Goshogawara-shi, Aomori prefecture. The study was carried out with a complex combination of action research, participant observation and literature review, detailing the process by which these organizations were formed and developed, with an overview of the organization, the reason for launching the organization, the situation prior to launch, and an overview of current business and their progress organized into a time series. As a result of the case study, 1) network rent clearly contributes to ensuring the continuity of the business, 2) the rent of social embeddedness becomes the basis of creation of other rents, 3) social enterprises not only accept rents but also create them, and distribute their rents to the participants of networks in order to manage to make them more involved in networks, 4) social enterprises were supported by intermediaries, and 5) the building and application of a network evolve through the accumulation of small successful experience.
