Abstract
Referring to the theory of organization, this paper seeks to examine the strategy adopted by Japanese Co−operatives against the changing market condition. Solicitation low price is quite understandable, but is not successful in that the amount of purchase per member has become stagnant. Implications to be lessened are the following:1. Co−operatives must consider not only lowering supply cost through reconstruction of operation but also strengthening cohesion by members to co−operatives which is the main advantage as enterprise against Plc. 2.There exists loyalty to co−operatives among members, which can be expected to make up the reliable base of co−operation.
