Abstract
In Niigata City, Niigata Prefecture, excellent results were obtained after agricultural land was integrated for use by leading farmers who made the most of the cropland intermediary management program. In this study, we clarified the development process of large-scale paddy farm management and the integration process of agricultural land as recently seen in Niigata City. We found that （1） the development of large-scale paddy farm management took place as a result of collaborations among small and medium-sized farms in rural communities covered by the program and the support of various agriculture-related organizations, and （2） integration of agricultural land was achieved because the collaborating farms' corporation had a large share of agricultural land in rural communities, forcing the communities to conform to agricultural land use adjustments made by the corporation.
