This study examines the introduction of the “middle voice” into the research on the leaders of community development, based on a review of studies outside the field of architecture and urban planning that use the middle voice. As a result, we were able to accumulate theories for the construction of a methodology for describing and analysing the formation process of motives and activity opportunities of the leaders of community development, such as a different perspective from ‘will = initiative’ in the formation of motives and activity opportunities, and the grasp of indirect and medium- to long-term influences.
